Basement Waterproofing: A Necessity for Every Building

Waterproofing foundation walls is a crucial step in the construction or renovation of a building. This process aims to protect the basement walls from moisture that can come from the soil and cause structural damage to the building.

If the waterproofing is not optimal, or if the drainage system is inadequate, it can lead to water intrusion, mold growth, and more serious problems. This step is often overlooked, but is extremely important.

Where Does the Moisture Threatening Your Foundations Come From?

Waterproofing foundations represents a significant investment that protects your property and well-being. It improves comfort for residents and ensures a healthy environment by preventing moisture from entering.

Many factors contribute to problems in concrete foundations. Soil type, humidity, freeze-thaw cycles, cracks in the concrete, inadequate drainage, and the building’s construction year are some of the most common factors.

In some cases, the nature of the soil itself can be a risk factor. Clay soil, for example, absorbs and retains water. This can cause significant moisture increase at the base of foundation walls, resulting in cracks. Even small cracks become real entry points for water infiltration.

It is also important to know that a failing drainage system only makes the situation worse. When it no longer functions properly, due to clogged drains, damaged pipes or improper installation, excess water can accumulate around the foundation, causing further issues.

When Water Infiltrates: Possible Consequences

Water entering a building’s foundation can cause many problems or aggravate existing ones. While foundation damage and structural or financial concerns are often discussed, the health risks to occupants should also be considered.

The freeze-thaw cycle in winter also exacerbates this phenomenon: water inside cracks freezes and expands as it solidifies, widening the fissures considerably and allowing more water to penetrate. Fortunately, these problems can be avoided with proper exterior waterproofing as well as an optimal drainage system.

Effectively Protecting Your Home

Keeping your foundations dry and free of water and moisture is essential. To achieve this, several methods and techniques are available to ensure optimal results. These include installing waterproof membranes, injection products, and various waterproof coatings.

At Béton Fondation Plus, we have opted to install a Delta-drain membrane, specially designed for structures below ground level. This membrane offers excellent performance in preventing water infiltration, especially during temperature changes and heavy rain, both common in Quebec.

We then apply an additional foundation membrane that protects the foundation from potential moisture damage. Featuring a honeycomb design, it controls water flow and continuously directs it toward drainage pipes, while also relieving hydrostatic pressure.

This work should not be taken lightly and requires specific expertise. To ensure your foundations are properly waterproofed, it is necessary to hire a company specializing in this area to do the job properly and in accordance with industry standards. A diagnostic assessment will be carried out, highlighting potential risks, the condition of existing installations, and more.

Maintaining a Functional Drainage System

To keep your foundations dry, it is essential to have a functional drainage system in place. Better known as a “French drain,” this type of installation is mandatory in Quebec when building new homes. It plays a key role in proper water drainage, helping reduce water accumulation near foundation walls and ensuring water is properly evacuated at ground level.
