Concrete chute type Betonform made of high-quality, armoured and vibrated concrete with the following quality requirements: medium concrete compressive strength 50 N/mm2 (500 kg/cm2), flexural strength, breaking load 12500 N (1250 kg). Water impermeability: maximum water penetration depth at the surface: 12 mm according to DIN standard 1048 (frost resistance).

Surface in exposed aggregate concrete or sanded according to the Betonform colour table. The inner concave portion of the chute has the dimensions 30x100x3 cm, is smooth and can be finished with transverse incisions for water drainage.

Slabs Type Betonform, square, made of high quality, vibrated and pressed concrete with the following quality requirements: medium concrete compressive strength 50 N/mm2 (500 kg / cm 2), bending strength (plate 50 x 50 x 5 cm), breaking load 12500 N (1250 kg). Water impermeability: maximum water penetration depth at the surface: 12 mm according to DIN standard 1048 (frost resistance).
Surface in exposed aggregate concrete or sanded according to the Betonform colour table. The structure of the slabs consists of two layers: an outer layer of 15 mm - the granulometry depends on the desired surface - and a second layer, a mixture of sand, gravel and cement in 1-15 mm particle size.
