Frequently asked questions

Both terms are used for a cap at the top of a masonry pillar. This range consists of concrete four-way caps. Confirm the finished pillar dimensions and the selected cap size before ordering.

Rectangular caps are offered in the sizes already produced. Send your measurements to check the existing range; manufacture to any arbitrary dimension is not promised.

Ask Ristone to confirm the actual profile of the selected piece. The generated detail image is illustrative and does not establish the presence of a drip groove on the product supplied.

Ristone manufactures these concrete products using a controlled production process. Long-term behaviour also depends on transport, installation and use. Mechanical impact, unsuitable handling or incorrect installation are examples of situations in which cracks can occur. Follow the handling and installation instructions; any reported problem is assessed individually before its cause is established.

The sloping geometry helps rainwater run off and reduces the possibility of water standing on the surface. Check the finished wall or pier width, cover dimensions, overhang and construction layout. Select the profile against the actual project dimensions.

Ristone pier caps are intended for outdoor use, with a hydrophobic treatment in the concrete mix to reduce water absorption and help lower the risk of freeze-thaw deterioration. On a UK or Irish garden or entrance pier, correct installation should let rain run off the sloping cap faces without standing on the pier top. Follow the applicable installation instructions. No frost-resistance class or freeze-thaw cycle count is declared; confirm suitability for the exposure of your project before ordering.

The listed Ristone three-way coping pieces are 500 mm long. The quoted width and length are piece dimensions. Longer runs use multiple pieces; joints, end conditions, end gaps and cuts are worked out separately for each wall section before ordering. Pieces of 1,000 or 2,000 mm are not in the current range.

That gives a nominal length comparison only. Record individual runs and agree joint widths, ends and the cutting layout before the order quantity is confirmed.

The historic range also lists straight-profile pieces in 500 mm lengths. Keep the profile explicit in your enquiry and ask Ristone to confirm the current piece and dimensions.

Use a stable, clean and properly prepared support, fixing materials suitable for exterior use and correctly formed joints. Follow the applicable installation instructions. If coping comes loose, Ristone assesses the cause before recommending a remedy.

Ristone coping is intended for outdoor use. A hydrophobic treatment within the concrete mix reduces water absorption, helping to lower the risk of freeze-thaw deterioration. For an exposed UK or Irish boundary wall, follow the installation instructions and ensure rain can run off the sloping faces rather than pond on top of the wall. No frost-resistance class or freeze-thaw cycle count is declared; check the available product information against your project requirements before ordering.

As a guide, 30–50 mm on each side of the finished pillar, depending on the shape of the cap and how it is fixed. The final size is confirmed with the quotation.

After. Measure the finished pillar, including render, stone veneer or brick slips. If the cladding goes on later, add its thickness and the adhesive layer to each face.

Yes, on a quotation basis. Transport, customs duties and import VAT are paid by the buyer. Products are made in Romania and quoted per order, depending on product, quantity and destination.

No. Amsterdam C54 is cast in concrete with additives. The face dimensions in the historic catalogue are 305 × 75 mm, with a thickness of 15 mm.

Send the wall area, openings and corner lengths, the substrate, the shade you prefer and the delivery destination. Current packing, availability and price are confirmed in the quotation.

Confirm the model code (Belgrad C60, Berlin C84, Oxford C69 or Ribe C05), colour sample, current dimensions and packing, joint width, corner detail and documents required for your intended use.

No. Berna C82 is cast in concrete with additives. The face dimensions in the historic catalogue are 240 × 70 mm, with a thickness of 15 mm.

Send the wall area, openings and corner lengths, the substrate, the shade you prefer and the delivery destination. Current packing, availability and price are confirmed in the quotation.

No. Bristol C25 is cast in concrete with additives. The face dimensions in the historic catalogue are 220 × 45 mm, with a thickness of 15 mm.

Send the wall area, openings and corner lengths, the substrate, the shade you prefer and the delivery destination. Current packing, availability and price are confirmed in the quotation.

No. Corby C58 is cast in concrete with additives. The face dimensions in the historic catalogue are 210 × 60 mm, with a thickness of 14 mm.

Send the wall area, openings and corner lengths, the substrate, the shade you prefer and the delivery destination. Current packing, availability and price are confirmed in the quotation.

These are concrete brick slips, rather than full bricks or fired clay slips. Select the model and ask for the information applicable to your intended installation.

The common product data lists C60M corner pieces for Belgrad and C05B corner pieces for Ribe. Confirm current availability and the corner detail for your installation.

Brick slip quantity calculations take an approximately 10 mm joint into account. Confirm the current box count and installed coverage before ordering. The convention is not confirmed uniformly across the range, and Oxford packing must be confirmed in the quotation.

The products are intended for exterior use and the concrete mix includes a hydrophobic treatment to limit water absorption. Reduced absorption helps reduce the risk of freeze-thaw deterioration. Correct installation and avoiding standing water matter; no frost-resistance class is declared.

Products are cast in moulds to nominal model dimensions. Small dimensional variations can occur during casting and curing. Check the pieces and trial the alignment before installation, allowing for the specified joints. Differences beyond acceptable variation must be assessed before fitting; no numerical tolerance is declared.

Mineral pigments are incorporated throughout the concrete mix and have good stability in light and weather. Surface appearance can evolve with sunlight, moisture, deposits and use. Subtle shade changes do not automatically mean the product has lost its properties.

Paid samples can be supplied depending on the product and availability. Sample cost and delivery are quoted before confirmation, including separate transport pricing for UK and Irish enquiries. For large orders, deducting the sample cost from the order can be considered.

Lighting, screen settings, texture and photographic conditions can change how the shade appears. Colour is incorporated through the concrete using mineral pigments. Small batch-to-batch variations are possible; for large areas, order the required quantity from one production batch where possible.

Very thin slips, approximately 7–10 mm, can crack during handling and transport. Inspect on receipt, photograph damage, record it on the transport documents and report it to Ristone. We assess each case and decide the solution after checking the cause: a top-up, replacement or another solution. Any allowance is confirmed in the quotation.

No. Oliva C66 is cast in concrete with additives. The face dimensions in the historic catalogue are 225 × 55 mm, with a thickness of 13 mm.

Send the wall area, openings and corner lengths, the substrate, the shade you prefer and the delivery destination. Current packing, availability and price are confirmed in the quotation.

No. York C61 is cast in concrete with additives. The face dimensions in the historic catalogue are 230 × 65 mm, with a thickness of 20 mm.

Send the wall area, openings and corner lengths, the substrate, the shade you prefer and the delivery destination. Current packing, availability and price are confirmed in the quotation.

No. Amsterdam C54M, Bristol C25M, Belgrad C60M and York C61M are monocomponent, one L-shaped piece. Ribe C05B is bicomponent, two pieces assembled at the corner.

Measure external corner height in metres and identify the corner-piece height in the model sheet. The sheet does not give a pieces-per-metre figure; the quantity, joint layout and pack rounding must be confirmed in the quotation.

Agree the corner detail according to that model's installation instructions before ordering. Berlin, Berna, Corby and Oliva have no corner piece listed. Oxford also has no corner listed, and its packaging must be confirmed with Ristone using the current sheet.

The installation order and course layout follow the chosen model's installation instructions, confirmed with Ristone before work starts. Request these instructions with the quotation.

Yes. Establish the cladding and adhesive thickness on each face, then size caps and coping from the finished dimensions.

For four fully exposed faces, use 2 × (width + depth) × clad height. Deduct hidden areas and record external corner heights separately.

No. It is a finish. Waterproofing, its junctions and the suitability of the substrate must be resolved in the project design.

The combination can be considered, with model and substrate suitability checked first. Include the different finish thicknesses when sizing caps and coping, and compare samples together.

It depends on the slip size and the joint. With a 10 mm joint, a 240 × 65 mm slip needs about 53 per m² and a 240 × 73 mm slip about 48. Use the formula 1 ÷ ((length + joint) × (height + joint)), with all sizes in metres.

With the joint, because the joint takes up part of the wall. Then check how coverage per box is stated: some figures are the net slip area, others include the joint. Dividing a wall area by a net figure gives too many boxes; dividing a net area by a figure that includes the joint gives too few.

On a relevant building as defined in regulation 7(4) of the Building Regulations 2010 (broadly, a building that has a storey at least 18 m above ground and contains one or more dwellings, an institution or a room for residential purposes), materials in the external walls must achieve Class A1 or A2-s1, d0, subject to the exemptions in regulation 7(3). Ask for the product's classification document before specifying it; Ristone confirms which documents exist for each product.

Yes, on a quotation basis, depending on product, quantity and destination. Transport, customs duties and import VAT are paid by the buyer.

Clay slips are fired ceramic, either cut from facing bricks or made as thin units; concrete slips are cast from pigmented concrete in moulds. Compare them on size, weight per m², corner pieces, colour range and the documents available for the exact product.

Ruppik’s article in Zi 8/2015 described ceramic slip declarations using EN 14411 and EN ISO 10545 tests and discussed EN 771-1 where a slip is part of a facing brick. It is historical context, not a current rule for every clay slip. Ask the supplier which current declaration basis applies to the exact product.

On a relevant building as defined in regulation 7(4) of the Building Regulations 2010 (broadly, a building that has a storey at least 18 m above ground and contains one or more dwellings, an institution or a room for residential purposes), materials in the external walls must achieve Class A1 or A2-s1, d0, subject to the exemptions in regulation 7(3). Ask for the product's classification document before specifying it; Ristone confirms which documents exist for each product.

In the Ristone range, Belgrad has a one-piece corner and Ribe a two-part corner. For Oxford and Berlin, ask how corners are finished before ordering.

Only if the insulation system is designed for a tile or stone finish. Systems with renderings and systems with discontinuous claddings, such as stone, are assessed under different European Assessment Documents. Ask the insulation system's supplier for the assessment and instructions that cover a cladding finish.

It depends on the model. From Ristone's product data, its concrete stone cladding weighs about 20 to 49 kg per m², before adhesive. Compare the figure for your chosen model with the limits of your substrate or insulation system.

Natural stone slabs for cladding are covered by EN 1469 and vary in colour and pattern from block to block. Concrete stone cladding is cast in moulds from pigmented concrete, with defined shades and data per model. Compare weight, corners, colour and documents rather than the label.

Yes, on a quotation basis, depending on product, quantity and destination. Transport, customs duties and import VAT are paid by the buyer.

No. D70 is a concrete product with a wood-effect surface. Pine and oak refer to the catalogue finishes, not the material.

The historic catalogue lists D70 at 720 × 225 mm and 35 mm thick. Confirm the current dimensions and the intended use before ordering.

A vehicle-load capacity and slip-resistance rating are not established in the available product information. Ask Ristone to check the proposed use before specifying the product.

The stepping stones are intended for pedestrian use. We do not have a confirmed slip-resistance test result. Check the proposed application and conditions of use with Ristone before choosing. Clean with water and a mild detergent; avoid aggressive methods and acids without checking compatibility. Maintenance and any additional protection should be agreed for the selected product.

Ristone stepping stones are intended for outdoor use. The concrete mix contains a hydrophobic treatment that reduces water absorption and helps lower the risk of freeze-thaw deterioration. For UK and Irish garden paths, follow the installation instructions and provide drainage through the bedding so water does not collect beneath the stones or pond on their surface. Ask for installation guidance for your ground conditions. No frost-resistance class or freeze-thaw cycle count is declared.

The factory and sales point described here are in Bacău, Romania. No UK office or showroom is listed. Contact the manufacturer directly to discuss your project.

Send the product or model, quantities or measurements, and the delivery country and town. If you need help with quantities, include the finished support dimensions, openings and corners as relevant.

Delivery to the UK and Europe is assessed for each enquiry, according to the products, quantity and destination. Transport, timing and receiving arrangements are confirmed in the quotation. The buyer pays transport, customs charges and import VAT for UK deliveries.

No. G70 is decorative cladding made of concrete with additives, with a solid-wood look, 720 × 225 mm and 10 mm thick. It is not a ceramic or porcelain tile.

No. G70 is 10 mm cladding; D70 is a 35 mm garden stepping stone. The wood effect does not make them interchangeable, so state the intended use in your enquiry.

The catalogue sheet lists indoor and outdoor use, in Pine (G70/P60) and Oak (G70/S30). Confirm the substrate and exact use with Ristone before ordering.

The buyer pays transport, customs duties and import VAT for UK deliveries. Confirm the applicable arrangements, transport quotation and import charges before ordering.

No fixed lead time is published. Timing depends on the products, quantities and destination and is confirmed in the quotation.

Unloading arrangements depend on the transport and site access. The customer must provide vehicle access and the people or equipment needed to unload unless these are included in the transport quotation. Report damage on receipt with photographs and notes on the transport documents, in accordance with the applicable conditions.

Small shade differences between batches are possible. Order the full quantity for one surface together where possible and keep the model, colour and invoice details for later enquiries.

Ristone does not recommend periodic repainting without a technical reason. The colour is part of the concrete, although subtle shade changes can occur with exposure.

For its products, Ristone recommends gentle cleaning with a soft brush. Collect loosened salts, and ask Ristone before using chemicals or treating deposits that do not brush off.

Do not use acids without checking compatibility with the particular product. Test any approved treatment in a small inconspicuous area, follow its application instructions and assess the finish after it has dried.

Send the finished pillar dimensions, finished wall thickness and clear length of each wall run, or cladding areas with openings and corner heights. Ristone checks the quantities before confirming the order.

Batch reservation and phased delivery can be considered after the quantity and programme have been checked. Neither is guaranteed automatically.

List the required documents in the enquiry. Availability is checked for the particular product before the quotation; documents that do not exist are not promised.

Divide each wall run by 500 mm and round up for a first estimate. The final count depends on joints, end gaps, cuts and whether suitable offcuts can be reused.

Agree the joint width and end gaps with Ristone and the installer for the chosen model. There is no universal joint width in this calculation.

Only if its length, edges and profile orientation suit the next position. Ristone and the installer check this in the cutting layout.

Use the pier-cap, coping-stone and brick-slip pages for the relevant catalogue details. The technical data page explains which current documents and packing information to request before specification.

Ristone can organise deliveries to EU countries and to the UK, depending on product, quantity and destination, on a logistics quotation. Send your postcode and quantities and you receive the cost and conditions before you confirm.

Small quantities can be considered, depending on the product and availability. There is no single minimum for all products; for small quantities Ristone quotes packing and transport separately, so you can decide whether it makes sense.

Check the goods on arrival, photograph any damage and note it on the transport documents before signing, then send the photos to Ristone. Each case is assessed and resolved, for example by topping up the quantity or replacing the damaged pieces.

Test centre positions on the ground with the people who will use the path. Spacing depends on their steps, the slab orientation and the route. There is no universal comfortable gap.

If the first and last slab centres are at the route endpoints and the target centre spacing is 700 mm, rounding to 14 intervals gives 15 slabs, with actual spacing about 714 mm. Confirm that adjusted spacing on site.

The historical D70 sheet describes pedestrian paths. Do not specify vehicle traffic without explicit technical confirmation from Ristone.

No. The historical G70 sheet describes a 10 mm thick facing product. D70 is a 35 mm thick slab. Confirm the current intended use and installation requirements for each product separately.

These photographs were supplied by Ristone. We do not arrange visits to customers’ properties; telephone ahead for a factory visit.

Ask for photographs of the model and colour you are considering. These images do not identify an exact model or shade; check your choice against a sample.

Send photographs and details so the situation can be assessed individually. Ristone distinguishes possible product defects from damage caused by external factors, impact, accidents or weather events. The solution is determined after the cause is identified, in accordance with the warranty conditions and applicable law.

Confirmed orders are followed through preparation and dispatch. If a situation may change the original timing, Ristone informs you in advance, explains the situation and gives an updated estimate. Transport updates are based on confirmations from the carrier.

Payment terms are agreed when the order is confirmed, according to the products, quantity and delivery arrangements. For made-to-order products, the quotation sets out the deposit and balance terms. Payment for factory collection is confirmed before collection.

Products carry statutory rights and guarantees under applicable law. Report a possible non-conformity with photographs and order details for assessment. Returns and surplus pieces are considered according to the order type, product characteristics and applicable legal provisions.

Use the contact details on the website for questions about your order, payment, production or delivery. Enquiries are passed to the responsible person. Ristone checks the order situation and explains the steps needed to resolve it.

Prices are provided on quotation. The final quotation identifies the products, quantities, unit prices, total value and delivery conditions. Transport and any logistics costs are communicated separately before order confirmation.

There are no fixed thresholds across the range. Pricing depends on the product, model and quantity; commercial terms for larger orders can be negotiated individually. Transport is calculated separately according to quantity, weight, palletisation and destination.

Check the substrate compatibility, exposure, fixing method and installation materials for the selected model before fitting. Products should not be used in applications for which they were not designed or verified. The complete limits of use have not yet been established; ask about your proposed application before specifying.

Installation is carried out by the customer or their building team. Ristone provides technical information and recommendations on compatible materials, substrate preparation, adhesives, joints and installation stages. Confirm the instructions available for the selected product.

You or your chosen carrier can collect from the factory in Bacău, Romania, with prior booking by telephone. Confirm product availability, order preparation and collection arrangements before travelling or sending your carrier.

We confirm receipt of your request. For standard quotations, we aim to reply within 24 working hours. For complex projects, large quantities or delivery outside Romania, including the UK, Ireland and other EU countries, the response time varies and is communicated to you. This is a response-time objective, not a contractual deadline or guarantee.

Under Regulation (EU) No 305/2011, it is the manufacturer's document stating performance against essential characteristics where a harmonised standard covers the product or a European Technical Assessment has been issued for it, subject to the regulation's exceptions. The new framework uses a declaration of performance and conformity. Ask for it with the quotation, for the exact product you are buying.

Regulation (EU) 2024/3110 applies in its main part from 8 January 2026, but product families move to it one by one. A product covered by a standard cited under the old Regulation (EU) No 305/2011 in principle stays under the old rules until a new harmonised standard is cited. Ask the supplier which framework applies to their product.

Ristone confirms with each quotation which documents exist for each product. Ask for them with your enquiry. Nothing about a product's classification is assumed from a photo or a catalogue line.

Great Britain has its own product marking and building rules. Ask your specifier or building control which documents your project needs, and ask Ristone which documents exist for the product before you order.

Current technical sheets and DoP or CE documents have not been supplied for publication here. A Declaration of Performance or CE documentation is not confirmed here for each product. Ask Ristone for the documents available for the selected product; their applicability and content are checked per product against your project requirements before ordering.

No. No fire classification is declared on this site. Ask for the applicable product documentation and have it checked against the project requirements.
