Rising damp treatment

Decontaminating walls, and indoor air. Improving wall thermal efficiency.

Stopping rising damp from soil for healthy buildings

The Domosec horizontal barrier is to stop capillary absorption from soil moisture.

Above ground damp walls

Installed above the ground level, this barrier can be combined with the patented screen against migrating damp.

Horizontal rising damp treatment

Firstly, the wall beneath the outside ground level is drilled.
Then, our bactericide, fungicide and hydrophobic resin is injected into the wall.

Wall drying by evaporation

The water evaporation time from the masonry varies from eight to eighteen months depending on:
- the thickness of walls,
- the homogeneity of masonry,
- the air permeability of the inner cladding and structure,
- ventilation and heating conditions. Ad hoc ventilation avoids stuffy air and allows moisture evaporation.

Damp check of the treated walls

The effectiveness of the rising damp treatment is then checked by measuring water content by total mass (up to 5% maximum).
The control method used consists in collecting samples from the treated walls: the sample moisture reacts with calcium carbide, producing acetylene gas, which pressure is converted in water content.

Repairing the coatings

After dampness treatment and damp check, the injection holes are sealed by a contractor (the customer's choice) who follows the terms described below.
Seals, paints and coatings that allow water vapour permeance should be used. Natural lime wash adheres to this principle. The coating is placed according to the requirements of DTU 26.1. The interior finishes (plaster or lime) should not exceed 1.5 cm thick.
