A revolutionary French Drain

Drenotube is the instant, pre-assembled French Drain available in UK through Wallbarn.

This new, ultra-lightweight drainage product means constructing underground drainage is made easier, faster and safer.

Improve drainage and prevent surface flooding around foundations and concrete structures, for road building, sports grounds without the heavy lifting. The days of inserting pipes, wrapping them up and covering with stones or shingle are over. Take the effort out of drainage.


  • Road construction

  • Walkways
  • Sports fields
  • Agriculture
  • Riding arenas and gallops
  • Around foundation walls
  • Gardens
  • Retro-fitting to areas with a high water table

The perorated drainage tube has been covered with polystyrene pellets which makes the tubes very lightweight. One person can easily carry a 6 metre length. The pellets are wrapped in a geotextile fabric and covered with strong netting. Ground water rises up during peak times and collects in the perforated pipe, running out of the system towards the drain.

Each piece can be laid by hand and connected easily together to form a land-drain as long as is required.

Key advantages include:

  • Lightweight
  • Much faster installation
  • Far safer
  • Less machinery required
  • Optimum drainage
  • Stronger, healthier plants
  • Accessible and installable for hard to reach areas
  • Ingenious clip system to fit multiple lengths together
