Isolation and waterproofing of foundations

Accueil » Isolation and waterproofing of foundations

Infiltration in the walls, flooding in the basement, uplift of foul smell, apparent mold, crack on the façade of the building… All these signs can be the result of a non-waterproof foundation sensitive to the upwelling of the water by capillarity.

Feeling of cold glass, explosion of energy expenditure, high heating consumption, air current in a room… Insulation prevents thermal shocks and coldness, but insulating materials do not stop as a bulwark against upwelling and cracking.

Insulation and waterproofing require two different and associated techniques to enable quality foundations

Our team of building experts is able to advise you on best practices in basement insulation and foundation sealing.

The difference between insulation and waterproofing of foundations

In new construction or renovation, the installation of insulating materials does not play a sealing role.House insulation

In order for the foundations to be waterproof and to avoid moisture rises in the walls, a waterproof membrane and drainage system must be put in place. The French drain andwaterproofing prevent the rise of water by capillarity in the walls and infiltration through the flooring. Avoiding this prevents the appearance of moulds harmful to the health of the inhabitants (respiratory problem, allergy, eczema on the skin …).

At the same time, the installation of insulating materials in the basement is very important. But you should know that insulation does not play a watertight role.

The function of insulation:

  • Prevent heat loss
  • Regulating indoor temperature
  • Avoid condensation
  • Be a bulwark against outside noise

Usually, the foundation sole is deep enough to be protected from the cold. When this is not the case, the insulation of the building prevents the thermal shock that causes cracks in the foundations and walls. This temperature difference can crack the concrete and increase the condensation on its surface and thus its porosity.

The different waterproofing materials for foundations

Projected membrane, self-stick membrane, honeycomb membrane, what can you choose to waterproof the foundations? Answer from your foundation expert below…

The honeycomb membrane

Composed of several small air alveoli, this semi-rigid plastic material (polyethylene) is effective. This honeycomb mat is ideally placed between the waterproof membrane and the embankment. Metal solins will be placed on the membrane to hold everything in place. It is a solution that reinforces the waterproofing of foundations.

A waterproof membrane

The Quebec Building Authority proposes the application of a waterproof coating in the form of a bituminous layer or rubbery coating.

This kind of protection can be found in several   forms:

  • Projected membrane
  • Self-stick membrane
  • Manually applicable membrane (trowel)

The three solutions are recommended to ensure good insulation and waterproofing of the   building:

  • A waterproof membrane to protect concrete
  • A honeycombed draining mattress to release hydrostatic pressure
  • A French drain at the sole to carry and drain standing water

Isolating the basement

Regardless of the type of foundation, the material for the structure does not have enough insulating capacity to keep a basement warm during the winter. Efficient insulation is essential for significant energy savings. There are several types of insulating products.

Polyurethane squirt

This concrete-powered product provides high protection and acts as a barrier to steam and air. It is particularly effective in specific and hard-to-reach locations.

Insulating panels

These Styrofoam leaves provide thermal protection and are resistant to water and moisture. Easy to install, they are often placed between the foundation and the interior finish. We sometimes place these leaves on a sole that is not deep enough to be protected from the cycle of freezing and thawing.

Insulating form

This technique is used for new constructions. It consists of using a special formwork that has an insulating capacity. Usually the formwork is completely removed when the concrete is hardened, but in the case of an insulating formwork it is left in place as it represents thermal protection.

A   question? Need a professional   opinion? Our foundation experts from Gatineau to Montreal answer all your requests. Our team travels quickly throughout the Quebec region to make an accurate diagnosis of the building and a free and personalized submission.

We offer solutions tailored to your needs with the best waterproofing materials for sustainable and sustainable construction.

Questions sur la réparation de fondation à Gatineau

Faut-il quitter les lieux durant les travaux?

Non il n’est pas nécessaire de quitter lors des travaux. Bien qu’il soit possible qu’une tranchée profonde surlonge tout le périmètre de votre maison durant les réparations, nous avons des installations sécuritaires pour que vous puissiez rester à la maison. Des rampes d’accès sont installées afin de permettre au client d’entrer et sortir à leur guise.

Peut-on baisser le taux d’humidité dans un sous-sol en réparant la fondation?

L’imperméabilisation et la pose d’un drain français protègent en effet votre sous-sol de l’humidité. Si la ou une des sources d’humidité  provient d’une faille de votre mur de fondation, la réparer va contribuer à régler le problème.

Les membranes installées par VOPAA inc. ont des propriétés imperméables et pare-vapeur afin de garder un sous-sol bien au sec. Sachez qu’un taux élevé d’humidité contribue à la formation de moisissure qui peut causer des problèmes de santé importants.

 

Vous pouvez toujours vérifier d’autres éléments tels que la plomberie et les fenêtres qui peuvent également représenter la cause d’une forte présence d’humidité dans l’air.
