Terrace Slab WORK White 90x90 cm Concrete Look Rough 20 mm R11 Rectified

Stepping outside without leaving the style of your interior behind. The terrace slab from the WORK collection brings the calm, clear aesthetic of concrete outdoors, in a format that covers generous surfaces with quiet elegance.

Concrete Look in Large Format, White and Textured Surface

The rough, matt surface in fresh white feels timeless and open. The subtle colour variation (V2) gives the surface a natural depth. At 90x90 cm, the square slab makes a clear statement, whether as a terrace covering or across larger outdoor areas. Rectified in production, it can be laid with tight grout joints for a clean, precise joint pattern.

Made for Outdoor Use

With a thickness of 20 mm and slip resistance R11, this slab is designed for outdoor applications. The stoneware is frost-resistant and meets abrasion class PEI IV. Due to the large format, we recommend an uncoupling mat as well as using a levelling system during installation. For terraces, we recommend professional installation with a suitable drainage system.

Frequently Asked Questions

Is this terrace slab really suitable for outdoor use?

Yes. With a thickness of 20 mm and slip resistance class R11, this slab is specifically designed for outdoor use. It is also frost-resistant. For a reliably safe installation, we recommend professional laying with a drainage system.

What does slip resistance R11 mean in everyday use?

R11 means the surface provides additional grip even when wet. This is especially important on terraces or outdoor areas used during rain. The rough surface texture further supports this property.

Why is an uncoupling mat recommended?

With large-format tiles like this 90x90 cm slab, temperature fluctuations and subfloor tension can cause cracking. An uncoupling mat significantly reduces this risk and is therefore strongly recommended during installation.

What does rectified mean for a terrace slab?

Rectified tiles have precision-cut edges that allow installation with very narrow grout joints. The result is a uniform, straight joint pattern that makes a significant visual difference, especially with large formats.

Which installation systems are suitable for this slab?

The use of a levelling system is recommended when laying this slab to achieve an even result. Installation should be carried out professionally by a qualified tradesperson.
