Description

Product overview
  • SOMTUBE® FTB and DRAINTUBE® FTB are composite drainage elements designed to drain water from the subformation level beneath concrete slabs, replacing traditional granular sub-bases and angled drains.
  • Designed for continuous operation in the groundwater table; requires connection to a network of drainage trenches and a discharge point (lifting unit).
  • The needle-punched geotextile combined with a polyethylene film enables pouring a concrete slab directly onto the product without risk of geotextile clogging by concrete laitance.


Applications
  • Under-slab drainage for industrial and commercial floors, buried structures and any construction requiring groundwater control.


Certifications
  • SOMTUBE® FTB: technical certificate validated by CCFAT.
  • DRAINTUBE® FTB/FTP: specifications validated by SOCOTEC; FDES and CSTB technical approval available for certain references.


Key benefits
  • Up to 45% reduction in installation time.
  • Drainage, mechanical protection and water barrier in a single product, reducing the number of installation layers.
  • Flexible, lightweight design for easier installation in corners and confined spaces.
  • No slab drying time required; economical—no granular drainage layer needed at the bottom.
  • Can be installed horizontally or vertically on various substrates; contributes to carbon footprint reduction.
  • Stable after backfilling—no uprooting risk.


Installation & compatibility
  • Must be connected to a network of drainage trenches and a discharge/lifting unit.
  • Suitable for permanent exposure to groundwater; compatible with direct concrete pouring thanks to the polyethylene film.
  • Can be dimensioned by an accredited design office to match site constraints.
