Drainage geocomposite DRAINTUBE® FTB

with mini-drainspolypropylenefoundation

DRAINTUBE® FTB is designed for draining water from the subformation level, under the concrete slab to replace traditional draining subbases (granular materials and angled drains). This system can operate continuously in the phreatic table. It must be connected to a network of drainage trenches and a discharge point (lifting unit). The polyethylene film makes it possible to pour a slab directly onto the product with no risk of clogging the geotextile due to concrete laitance. Certifications : DRAINTUBE® FTB is subject to a technical certificate validated by CCFAT (Commission in charge of technical advice).
