The renovation of one of the roofs of the company Innovation Trading and Services.
Initially made of sprayed polyurethane, this roof only allowed the mechanical fixing of the waterproofing membrane.
A 300gr geotextile was unrolled on the whole roof (chemical separation) covered with a SIKA 15G membrane (1.5mm) mechanically fixed on the concrete support.
This fixing technique guarantees the stability of the waterproofing without risk of uncoupling it.
