Dr. Canalisation Vendée
Experts in pipe lining in the Vendée and Pays de la Loire regions.
Pipe rehabilitation without excavation work
In the Vendée region, the clay-limestone subsoil shifts with the seasons: it swells with winter rains and shrinks in the summer. These movements weaken underground pipes, which eventually crack or become dislodged. Add to that the roots of oak and poplar trees that seep into even the smallest cracks, and you end up with pipes that need to be replaced.
Pipe lining solves the problem without excavation. A flexible resin liner is inserted into the existing pipe through an access manhole. The liner is then cured in place using UV polymerization. The result is a brand-new, smooth, and watertight pipe molded inside the old one.
There are some telltale signs: persistent sewer odors in the house or yard, standing water around a manhole, an unusually green patch of grass over a pipe (a sign of a leak), backflow in the bathrooms after heavy rain, or a failing sewer system inspection during a sale. In all these cases, a camera inspection can confirm the actual condition of the pipes.
Yes, and this is one of the most common issues in the Vendée region, especially with oak, poplar, and willow trees growing near pipes. Sébastien starts by cutting away the roots with a cutting robot, then installs the lining sleeve. The hardened resin creates a watertight barrier that the roots can no longer penetrate. It’s a permanent solution, not just a quick fix that merely postpones the problem for a few months.
That is precisely its strength. The resin liner has a certain degree of flexibility that allows it to absorb minor ground movements without cracking, unlike rigid clay or concrete pipes. It has a service life of over 50 years, even on shifting ground.
The price varies depending on the length of the pipe to be treated and its diameter. There is no set price list, but as a general rule, you’ll save between 30% and 50% compared to a traditional replacement involving excavation and site restoration. Sebastien will provide you with a detailed, free estimate after the camera inspection, with no obligation.
Hiring a contractor from Nantes or Angers for tree pruning in the Vendée means incurring travel expenses and dealing with longer turnaround times. Sébastien is based in the region. He’s familiar with the soil in the Vendée, the local tree species that pose problems, and the types of homes found from the bocage to the coast.
