The Eurovent GEOU 20 drainage foundation foil made of high-density polyethylene (HDPE)characterized by parallel 20 mm dimples. Foil is designed for use as vertical and horizontalwaterproofing layer in buildings. The product is extremely resistant to compression and itslarge dimples increase the drainage performance. In addition, the foil also forms a layer ofthermal and acoustic insulation. The product is resistant to acids, alkali, solvents, bacteria,funghi as well as damage caused by roots.
The Eurovent GEOU 20 drainage foundation foil is designed for use as vertical insulation of foundationfoils, especially recommended for application at in-depth engineering in underground railways andtunnels, underground parking lots and other similar constructions which require reliable protectionand drainage. Higher dimples increase the draining surface. The foil proves an excellent solution forsecuring constructions where there is not enough room to establish the formwork – it is suitable forinstallation between the shotcrete and the final concrete wall. Horizontal applications includeprotection against penetration of water in buildings where deep foundations are exposed to the riskof temporary fluctuations of subsurface water levels. In such cases, it is laid with a slope between thefoundation slab and the screed or concrete screed.
