EXPRESS BETON B-50 447
Fast-setting, highly durable concrete mortar, reinforced with basalt fibers.

Specialized high-strength concrete. Used for underfloor heating, distribution layer, thermal insulation and as a floating undercoat. Designed for terraces and balconies, and for fixing fence posts and making concrete elements. Primer for ceramic tiles, panels, parquet floors. Water resistant, frost resistant.

Used as a base in a floor heating system, floating on thermal insulation, separating layer and linked with a bed.

B-30 quick-setting concrete is also intended for screeds and substrate levelling layers. It is especially recommended in areas where the setting rate is of particular importance (corridors, passageways etc.).

Suitable for anchoring fence piles.

Minimal layer thickness: base binding with the groundwork > 25 mm, base on separating layer > 35 mm, base floating on the thermal and/or acoustic insulation layer > 40 mm, anhydrite base in the floor heating system -> 45 mm (external diameter of the heating element + thickness of the layer above heating elements min. 30 mm).
