Overview

Concrete Alloy Techslate Stone-Look Flooring

The look of polished concrete in a Swiss-made 7.5 mm click plank that is waterproof, fireproof and quiet underfoot. Concrete Alloy delivers the cool, urban character of raw concrete without the cold, hard slab. Each 920 mm x 460 mm (36 7/32 in x 18 7/64 in) plank is finished with direct, lightfast digital printing and a micro-bevelled edge, so the surface keeps its colour even in sun-drenched rooms, rated above 7 on the 8-point lightfastness scale. Under the surface, this is mineral flooring, not laminate. A highly viscoelastic intermediate layer sits over a mineral carrier plate, with a GREEN Sound impact underlay bonded to the back. The result is a floor that is 100% water resistant, shows 0% thickness swelling after 24 hours in water, and carries an A2fl-s1 fire rating. That mineral core also makes it remarkably stable: dimensional movement is under 0.03%, which allows installations of up to 1,000 square metres without expansion or separation joints. Planks click together with the Uniclic profile and float over the subfloor, above grade, on grade or below grade, including over electric or hydronic radiant heat. With Class 33 commercial durability and the KORUS wear surface, Concrete Alloy is built for cafes, offices, salons, retail shops and busy family homes alike. When a floor reaches the end of its service life, it can be dismantled and 100% recycled through a second-life process.

Why this floor

  • Waterproof mineral construction: 100% water resistant with 0% thickness swelling after 24 hours (EN 317).
  • Fireproof: A2fl-s1 fire classification (EN ISO 9239-1), the top rating for a flooring product.
  • Quiet: approx. 19 dB impact sound improvement from the integrated GREEN Sound underlay, plus 35% in-room sound improvement (IHD-W-31).
  • Commercial Class 33 and residential Class 23, with AC5 abrasion resistance (over 10,000 cycles, WR4) under the KORUS wear surface.
  • Exceptional stability: under 0.03% dimensional change, so up to 1,000 m2 can be laid without expansion joints.
  • Sun-safe decor: lightfastness above 7 on the 8-point ISO 105 scale keeps the concrete tones true in bright rooms.
  • Healthy indoors: emissions below 100 ppm per AgBB, backed by a Green Guard Gold certificate.

Common questions

Common questions

Can I install this over in-floor radiant heat?
Yes. Concrete Alloy is compatible with electric, hydronic and underfloor heating systems, and its low thermal resistance of approx. 0.05 m2 K/W lets warmth pass through efficiently.
How does it handle below-grade and other damp locations?
Yes. It is approved for below grade, on grade and above grade installation, is 100% water resistant, and shows 0% thickness swelling after 24 hours (EN 317), so moisture-prone spaces are not a problem.
How does it hold up to pets and heavy traffic?
Very well. It carries commercial Class 33 durability, AC5 abrasion resistance (over 10,000 cycles), R 10 slip resistance and grade 5/5 stain resistance, and rolling chair casters leave it unmarked. It is used in airports, hospitals, restaurants and retail shops.
How is it installed?
It floats over the subfloor using the Uniclic click-lock profile, with no glue or nails. Thanks to dimensional stability under 0.03%, areas up to 1,000 m2 can be installed without expansion or separation joints. Plan for about 10% overage when ordering.
