CAPILASIL® is a range of colourless water repellents for walls and frontages developed to achieve maximum protection against surface or rising damp problems.

Cleaning up the building with a water repellent treatment is one of the first steps in a renovation project. CAPILASIL® water repellent treatments allow your “hydrophilic” materials to become “hydrophobic” while maintaining their permeability to water vapour.

Depending on the needs and the nature of your humidity problems, the formulations of the CAPILASIL® range vary to offer maximum success to your frontage remediation, terrace and rising damp projects.

CAPILASIL®, your water repellent solution against humidity

The CAPILASIL® range of water-repellent allows you to start your projects on the right footing with dry and healthy spaces. Thanks to walls and frontages treated against humidity, you are free to consider all types of developments and renovations.

The benefits of CAPILASIL® water repellent solutions

Protects exterior walls from driving rain.

Prevents frost damage and therefore the risk of cracking.

Allows materials to continue to “breathe” and therefore limits condensation dampness inside.

Induces heating savings because dry materials offer better thermal insulation than wet materials.

Reduces moss and mildew formation and prevents efflorescence.

Keeps frontages clean.

Prevents salts from appearing

Surface humidity

Surface humidity

Our surface water repellents have been designed to treat most surfaces made of porous materials (walls, joints, etc.). CAPILASIL® solutions offer an exceptional water vapour permeability and ensure the waterproofing of treated materials.

Brick, concrete, stone or even wood: whatever the type of surface to be water repelled, there is a suitable CAPILASIL® solution.

Protection of frontages by impregnation



CAPILASIL® solutions dedicated to surface water repellency are easily applied by pouring or brushing, from bottom to top.

A “fresh on fresh” application is recommended in most cases. This is the method that allows the best penetration of the product, because the second application makes the previous one penetrate deeper into the surface. The deeper the penetration, the longer the life of the treatment. We offer a 10-year warranty on frontages (see our terms).



The formulations of CAPILASIL® solutions vary according to the nature and porosity of the surface. Our teams are available to advise you on the best solution according to your sanitation and dampness treatment project for your frontages and terraces .

Product tested by the C.S.T.C. for surface water repellency (Report HD-340/133-83).



All CAPILASIL® solutions are available in 5 and 25 litre drums. Consumption varies according to the porosity of the surface, from 0.2 to 0.5 L per m˝.

For specific cases, do not hesitate to ask us for advice, our experts are here to help you.

Rising damp

Rising damp

This type of dampness is caused by water absorption through capillary action.

When the capillaries are thin, moisture migrates slowly, but the pressure is high and the rise is significant, up to two metres high. When the capillaries are larger, moisture migrates more quickly, but the pressure is lower. Rising damp generally ranges from 80 centimetres to one metre high.

The CAPILASIL® solutions are applied by injection and form a hydrophobic barrier at the bottom of the walls. In aqueous or solvent phase, they allow the drying and protection of walls against rising damp.

Wall treatment by injection



The CAPILASIL® water-repellent solutions are applied by means of an injection pump (rental is possible) and according to a specific method.

Practical studies prove that the treatment of buildings against rising damp by injection with the CAPILASIL® water-repellent solutions more than 40 years ago is still effective and will remain so for a long time. With treatment and injections carried out in accordance with our technical data sheets, your buildings are protected and remain healthy in the long term.



The CAPILASIL® water-repellent solutions, whether in solvent or aqueous form, are formulated from oligomeric siloxanes with high concentrations of active ingredients. This product has a hydrophobic action, excellent penetration power and very good activity, even in the presence of harmful salts such as nitrates, with a “hardening” agent.

We also offer solutions for treating wood against moisture by impregnation.



The CAPILASIL® solutions are available in 5 and 25 litre drums. Consumption is 1.5 to 2 litres per running metre and per 10 cm of thickness.
