FOR EASY-CARE OUTDOOR LIVING.
ON-TREND. DISTINCTIVE. EXTRA-THICK.
ROUNDED PEBBLES. FINE-GRAINED MATRIX. EXTRA-THICK PORCELAIN STONEWARE.
Gravel Blend‘s surface finish is modelled on conglomerate rock, with a fine-grained matrix and river-pebble inclusions. Is a naturally occurring type of stone that has formed over the course of millions of years since the Alps began to take shape.
Gravel Blend combines the primeval impression of ‘conglomerate‘ with the utility of an easy-maintenance, non-slip outdoor surface. In a distinctive 2 cm extra-thick 40 x 80 cm stone block format.
AS "EASY" AS IT IS "EFFECTIVE".
STRÖHER terrace slabs feature Extrutec® Hardglaze 3 glaze. This special hard glaze improves not only the slip resistance in wet conditions, but also the ease of maintenance of the patio slabs; this is already outstanding due to the production process, which involves an extrusion procedure i.e. being drawn from a damp clay rather than being pressed from dry clay powder.
Extrutec Hardglaze seals the very last pores on the ceramic body, with the high-fire sintering at 1200°C having already provided a nearly perfect seal. So the last chance for moss, algae and insects to find a place to thrive is eliminated. Ströher remains soiling-resistant and environmentally friendly even in the face of grease, red wine, damp or other challenges. As cleaning chemicals are not necessary. Warm water is sufficient.
AS "SAFE" AS IT IS "SIMPLE".
Ströher terrace slabs are made from a robust 20 mm solid mass, which provides the necessary weight when laid loose. In the case of permanent installation, the highly structured reverse-side texture also provides the necessary adhesive strength.Ströher terrace slabs are ideal both for renovations as well as for the new construction of terraces, balconies, roof terraces, paths and driveways. Wherever the flooring has to cope with high loads, static challenges and problematical substrates. Ströher terrace slabs can be laid permanently orloose like natural stone or concrete.
