Rising damp treatment
Decontaminating walls, and indoor air. Improving thermal efficiency of walls.
Stopping rising damp
Barrier, layer and screen against migrating damp, these moisture treatments, combined or on their own, are to stop capillary absorption from soil moisture (rising damp or laterally migrating damp).Before the installation of this moisture treatment, the salpeter contaminated coatings are to be purged and the joints to be bared.
Installation of the dampness treatment
- Treating rising damp with Domosec barrier
First of all, the wall is drilled with two lines placed holes at its base. Then, our hydrophobic resin, bactericide and fungicide is injected into the wall.
- Treating migrating damp with Domosec layer
After the wall beneath the outside ground level being drilled, our hydrophobic resin, bactericide and fungicide is injected into the wall.
- Treating migrating damp in three dimensions with Domosec screen, patent filed by Domosystem
After the wall beneath the outside ground level being drilled, our hydrophobic resin, bactericide and fungicide is injected into the wall. The installation of the Domosec screen is conducted in accordance with the terms of patent application 0215236.

The following steps are identical for each of the three dampness treatments.
Wall drying by evaporation
The time required to evaporate the water in the masonry varies from six to eighteen months depending on:- the thickness of walls,
- the uniformity of masonry,
- the air permeability of the inner cladding and structure,
- the conditions for ventilation and heating.
Ad hoc ventilation is essential: stale air prevents the natural evaporation of moisture.
Check of the water content of the treated walls
The efficiency of the moisture treatment is then checked with reference to the allowable water content, up 5% from the wet mass. The control method used is through reaction in samples taken in the treated walls: the moisture in the sample reacts with the calcium carbide, producing acetylene gas, and the resultant pressure is used as a measure of moisture.Repairing the coatings
After dampness treatment and result check, the injection holes are sealed by the contractor (the customer's choice) who follows the terms described below.Seals, paints, and coatings that allow for the permeability of water vapor 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.
Domosystem is committed to its customers (moisture treatment guarantees).

Indoor air quality training
Health and productivity of staff? Air quality in tertiary buildings?
High environmental quality of buildings?
HEQ, this process integrates "global cost": apprehending the life cycle of buildings is a work of anticipation.
It results in:
- reduced exploitation costs,
- environmental and social benefits…
A HEQ operation will perform even better since the project vision is actually shared by all –designers, builders, owners, operators, occupiers-.
Air quality? Energy efficiency?
Reconciling the two upstream avoids the costs related to amendment works after building or refurbishment: work costs, social costs –health, absenteeism- and environmental impacts.
Exploitation mode and ways of life have a notable share in “global cost”.
