Non-woven drainage membrane TERAPRO® BAT

with mini-drains

Waterproof geocomposite, terapro® BAT , is placed horizontally around buildings, protecting grounds sensitive to water, limitating the phenomenon of clay swelling by pushing the seepage back toward a drain. Advantages ● terapro® BAT is rotproof in the soil, and is easy and quick to install, being single-piece: the waterproof sheet is protected on both sides by punctureresistant geotextiles joined together in the factory, which do not slip relative to one another during backfilling, Detailed description ● the product consists of needle-punched, nonwoven polypropylene punctureresistant protective geotextiles of 300 g/m² mass per unit area, joined in factory by a hot-melt process to a waterproof polyethylene sheet. Assembly of the waterproof polyethylene sheet should be feasible by hot air gun and with an automatic machine. T h e d y n a m i c p u n c t u r e resistance in accordance with ISO 13433 must be less than 1 mm, and the static puncture resistance greater than 3.6 kN.
