House expansion on foundations in Gatineau

Accueil » House expansion on foundations in Gatineau

A house expansion that requires the construction of deep foundations should be considered a major construction site, nothing to do with a renovation.

The technical stakes are immense and the responsibility of the manufacturer very committed.
The extension of the house that will come out of the ground must be solid, its foundation watertight, its floor drained and perfectly linked to the foundation of the existing part. 

Needless to say, the choice of company is a key decision

  • Has 20 years of experience
  • Expert in foundations of all types
  • Managed more than 150 construction sites across Quebec 

 

Expanding your home on solid   foundations: why?

You can expand your house:

  • Adding a floor (attic layout or one-storey construction)
  • Digging a basement
  • By making an extension such as a garage, a shed
  • By building a terrace or patio extension on piles or on a concrete slab

The home expansion that brings the most saving of living space in square feet is one that relies on new foundations capable of supporting several levels of construction.  

Baseneon expansion

That said,   home expansion which brings the largest living space remains the one that includes the construction of new foundations. In this case, in fact, the space saving   is possible on two or even three floors.

Beyond the robustness and living space acquired, the foundation house expansion brings enormous added value to the home.

 

What cost, what price for a house extension on foundations?

 

Because every house is different, no expansion project ever looks the same. The year of construction, the buildings, the expansion project itself involve specific and specific solutions for each project.

The cost variables involved in the foundation extension submission   are:House expansion price

  • Excavation work, 
  • The pouring of concrete,
  • The integration of the existing structure with the new one (including the architect’s study), 
  • The installation of French drain
  • Post-earthwork landscape 

These construction parameters themselves depend on physical, environmental and legal factors.

  • The study of the structural engineer; 
  • City/hydro building permits and permits; 
  • The general logistics required for the site;
  • The type of soil to manage
  • physical space available for equipment to work (public space and neighbourhood management) 

Although we do not do any such work, you can get   advice from our a foundation specialist in Quebec.

  

Possible subsidies 

Expansion work is eligible for financial assistance, see this article.

 

 

The steps of a house extension project on foundations 

Your project manager will take into account and obtain permits related to your work according   to:

  • The Building Act
  • City regulations
  • The building code
  • Workplace safety
  • And even Hydro Quebec regulations when you work close to the public road.

 

Many laws and regulations come into play in this type of heavy work, obtaining permits is a job in its own right. 

These technical and administrative steps contribute to the logistics of the work, they are the necessary legal preliminaries because this type of construction cannot suffer from improvisation or amateurism.

 

What kind of foundation is best for your enlargement?

Expanding his house we have seen, can technically be considered in different ways. It depends on the destination of the living space volumes created, the new useful spaces.    

Possible types of   foundations:

  • Deep, semi-deep foundations

the more often suited to home enlargement,   this type of foundation is the main topic of this article. They will seek their support, their stability   at five / seven meters, (Up to 12 m) depending on terrain). Pressed piles can replace the sole to support the load. 

These foundations are the most expensive of course.

Setting up foundation piles

  • Superficial foundations.  

Suitable for lightweight constructions only, the cast soles are necessarily wider than the supported element. Professionals have a choice between two types

  1. Insulated soles that often form the foundations of poles
  2. Shooting soles used to build concrete block walls. The spinning soles spread the loads over a larger one avoiding the sinking of the construction.

To build on these foundations the soil must be very stable and its support layers are located less than 1m deep.

 

  • Special 

    Foundations on write off 

     

    A raft is a flat slab that covers the entire built surface (or even, will be wider with its console) on low-bearing ground, it forms the foundation itself and assumes not very heavy built loads. 

    the soil should be well   drained.

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.
