• Rising damp - Saltpeter
  • Drying out of damp basements
  • Condensation - Mould
  • Dry rot treatment
  • Wood insects treatment
Rising damp coming from the ground degrade the walls of your basements and ground floor: the paint peels off, the ceilings crumble, a deposit of salt appears …

Hydrotec offers you a solution by injection and application of a surface protection. Your walls become dry and healthy for an unlimited period. And as proof, we offer you a 30-year warranty!

The walls against the ground become damp from contact. Moisture and salts slowly degrade them. One solution is to create an internal casing (with or without a draining trench) and a draining membrane on the ground.

Our exclusive Hydro+ casing solution is guaranteed and has been proven since 1988.
For reinforced concrete structures (basements, car parks), resin injections are done in addition to the casing.
Depending on your situation, it will be possible to position, after making an external trench, a waterproof membrane between the wall and the ground. 10 years warranty

Hydrotec Traitement de la condensation et des moisissures
Are spots invading your walls behind the furniture, in the corners or around the windows? It is probably mould caused by condensation problems.
This may occur due to ventilation problems or insulation defects causing thermal bridges.
To effectively combat condensation and mould, Hydrotec installs a range of ventilation devices (single MCV and dual frequency DFV ventilation systems).
We also insulate facades to eliminate thermal bridges and the inconveniences associated with cold walls (solid walls).

Elimination de la mérule et protection des charpentes
A genuine calamity and danger for your home, dry rot is a fungus that develops in the presence of moisture and cellulosic material (usually untreated wood, cardboard, etc.). It particularly likes unventilated, hot, humid and dark places. In the event of an attack by dry rot, Hydrotec prepares the site, treats the fungus and proposes rehabilitation work: repair of the floors, repair of the ceilings, replacement of stairs, etc.
