How can I dry out a damp wall?

Why combat damp in walls?

Dampness inside homes is a real scourge that needs to be dealt with properly. Dampness causes a great deal of damage in the home, weakening the structure of buildings and causing aesthetic damage to walls. The presence of damp in walls can also lead to the appearance of saltpetre and mould, which are dangerous to health. What’s more, the presence of damp in a home leads to higher energy consumption, so it’s in your interest to limit its presence in the walls.

What causes damp in walls?

In a poorly insulated home with a water-logged environment, damp can appear in a number of ways:

• Seepage through façades and roofs
• Condensation
• Rising or capillary humidity

Capillary damp is undoubtedly the most damaging type of damp in a home. When the soil is very watery, poorly sealed and porous walls will suck up the water present in the soil and gorge themselves with moisture. It is therefore more difficult to treat this problem, as the entire thickness of the material is affected.

How can I effectively dry out damp walls?

Dampness in walls is a major problem, but fortunately there are solutions available to professionals to combat it effectively. The Groupe Berkem offers a whole range of products to treat damp and all the problems it causes: the Xilix Blockaqua range, the Xilix Blockaqua range and the Xilix Blockaqua range.

Groupe Berkem treatments for damp walls

The Groupe Berkem offers the Xilix Blockaqua range for effective moisture control. These products create continuous, watertight barriers. These formulas are developed using silane/siloxane resins and are injected directly into the heart of walls affected by damp.

• Xilix Blockaqua is a ready-to-use formula
• Xilix Blockaqua cream is a ready-to-use, highly concentrated water-repellent cream. This cream is used on sites with a high level of humidity.
• Xilix Blockaqua C is a concentrated formula that must be diluted with water before use.

This range of products can be used whatever the nature and thickness of the wall to be treated.

Additional Groupe Berkem treatments for damp walls

To further protect walls, Groupe Berkem also offers a range of complementary products to protect walls against damp. These products are applied to the outside of walls, unlike the previous products.

• Xilix Blockaqua Salt is a penetrating product designed to treat salts that appear in the presence of high humidity. This product purges the wall of hygroscopic salts and prevents them from developing.
• Xilix Blockaqua Hydro is a formula that protects walls against splashes of water and other aqueous substances such as oil and organic substances. This product is based on silanes/siloxanes and has the advantage of not altering the colour of the wall being treated.

This complementary range of products provides optimum effectiveness against damp in walls. Ideally, Blockaqua products should be combined as required.
