UHPC tiles: frequently asked questions
Quick answers to the questions architects, designers and contractors ask most. Follow the links for detailed guides.
The material
- What is UHPC?
- Ultra-high performance concrete: a dense, fibre-reinforced cementitious material with very high strength and durability, allowing thin tiles and panels.
- How is UHPC different from normal concrete?
- It uses fine particles, a very low water content and fibres, giving much higher compressive and flexural strength and very low porosity.
- Is UHPC the same as GRC/GFRC?
- No. Both are fibre-reinforced, but UHPC has a denser, stronger matrix. GRC is often used as a thin skin on a frame.
Performance
- How much do UHPC tiles weigh?
- Roughly 2.4–2.6 kg/m² per millimetre of thickness, so about 24–26 kg/m² at 10 mm. Always use the manufacturer's data.
- How thin can UHPC tiles be?
- Commonly 8–20 mm depending on size and use; facade panels are sized by structural calculation.
- Are UHPC tiles fire-resistant?
- UHPC is mineral and many products achieve high reaction-to-fire classes, but check the classification report for the exact product.
- Can UHPC be used outdoors?
- Yes. Its low porosity typically gives excellent freeze–thaw and weather resistance. Confirm test results for your climate.
- Are UHPC floor tiles slippery?
- It depends on the finish. Textured, sandblasted or honed finishes give higher slip resistance for wet or external areas.
Installation and care
- How are UHPC tiles installed?
- Interior tiles are usually bonded with flexible adhesive; facade panels are mechanically fixed to a subframe; terrace tiles often sit on pedestals.
- Do UHPC tiles need sealing?
- Often yes, particularly in kitchens, bars and bathrooms. Follow the manufacturer's recommended sealer.
- Can UHPC tiles be cut on site?
- Usually with diamond tools, although factory cutting gives the cleanest edges.
Cost and our service
- How much do UHPC tiles cost?
- Prices vary with size, thickness, finish, customisation and quantity. UHPC is generally premium versus porcelain and often competitive with stone once installation is included.
- Is your service free?
- Yes, for architects, designers, specifiers, developers and contractors. Manufacturers pay us when introductions lead to business.
- How quickly will I hear back?
- We aim to review briefs promptly; matched manufacturers then contact you directly about samples and pricing.
