Waterproofing & Damproofing

GUTTABETA T20 GARDEN

Gutta® T20 garden provides a draining membrane with a water reserve for roof gardens through the small 20mm cups formed by the knots. This “reservoir effect” regulates the water accumulation, preventing an accumulation of heat. The holes are spread over the sheet so as to ensure aeration to the roots of grass and plants. Water in excess is drained away through the holes percolations through the air space formed by the knots and the waterproof. By using this product it is not necessary to use aggregates on the terrace or on the roof to create drainage, which reduces the imposed loading on the structure.
