The foundations of a house: essential for a good one structure 

You have heard that the geographical area that you appreciate and towards which you would like to settle does not offer soil that allows the installation of traditional house foundations. You are afraid that these will be too deep and require specific studies with higher costs to pass on to your mortgage.

To  build a classic or passive house, a  preliminary study of the land  is essential , it allows you to analyze the nature of the soil and anticipate the any ground movements or structural reinforcements necessary for the proper location of the house. 



What are the foundations of a house? 

Are you looking to build your house? After several appointments, you now know that the foundations of your future home are essential for its solidity and stability. Pour éviter d'avoir d'ici quelques années des infiltrations, tassements et fissures structurelles,_cc781905-5cde -3194-bb3b-136bad5cf58d_the foundations must be carried out in the rules de l'art. 

There is, in fact, always someone who knows someone who had to dig and implant house foundations up to 10, or even 15 meters deep_cc781905 -5cde-3194-bb3b-136bad5cf58d_! Because it is true that depending on the nature of the ground, the foundations can go down deeply to ensure the durability of the house!

To be sure to  control your construction project, it is necessary that you are aware of the nature of the land you plan to buy or that you already own. It is quite possible to lay the foundations of your house yourself, regardless of the nature of the ground. But depending on the geological context, the house foundations must be more or less reinforced, more or less deep and you are playing with the lifespan of your structure!

The foundations of a house  allow the construction to be implanted in the ground. Carried out after the smoothing of the ground, they must be preceded by a study of the ground, to analyze at what depth they must be built. They make it possible to ensure the stabilité  of your house and to avoid its subsidence.

The nature of the terrain affects the depth of the foundations, but also the type of construction. Thus a  timber frame house   will require shallower foundations than a traditional construction type house. This is due to the weight and volume of concrete or wood to enter the work.

Digging deep foundations to build a house can exponentially increase the total budget ranging from 5,000.00 francs This is therefore   very important information to have when choosing your land.


What foundations for your house and at what price? 

Usually the  depth of house foundations  for land of a stable nature is about sixty centimeters on average. The height and price of the foundations of a house can particularly  vary depending on many factors:

  • la nature de votre terrain : un expert géologue ou géotechnicien, analyse la nature of the soil in order to be able to provide a study and recommend a foundation depth as well as reinforcement diameters. The more stable the ground, the shallower the foundations. These can go down to several meters if the geological nature of your land does not lend itself to it,

  • le type de construction choisie: in fact, timber frame houses are much lighter than concrete block houses. They do not require particularly deep foundations (except in the case of unstable ground). The two-storey house foundations  are designed to support the most important structure to be supported.


How to build the foundations of a house?

When the ground has been smoothed by several  earthworks steps, the next step concerns the foundations of the house. From the plan of the house,  trenches  must be marked on the ground at the locations of the future exterior walls.

We're talking about excavations : these should be twice as wide as your intended wall width. If your wall is about twenty centimeters wide (classic breeze block 20x20x50cm), then the average width of the trenches will be 40 cm.

It's a long-term job and it is necessary to rent equipment  to be able to move forward. A mini digger is a minimum and many extra arms too. If no soil study has been carried out beforehand and you rely on the seller's statement concerning the nature of the land, it is possible that all the savings made by doing your own house foundations will be swallowed up in a few years, if the foundations were not deep enough.

Indeed,  cracks,  subsidence, landslides, can cause considerable damage to your house, even making it uninhabitable._cc781905-5cde-3194- bb3b-136bad5cf58d_

Digging house foundations is not trivial and the structure of your house resting on this base, it is necessary to start on the right foot! foundations at professionals near you and compare the prices!

The excavations dug, the bottom must be lined with stone, and clean concrete must be poured before the installation of the iron reinforcements, the dimensions of which are given by the geological study. -3194-bb3b-136bad5cf58d_

You can then pour the footing and then pour the foundations. 

Be aware that it is important not to work and pour house foundations in freezing weather.  Le  drying time is 21 to 28 days. 


  • Direct foundations (shallow foundations)

  • Block foundations (bricks)

  • Foundations sur  Footings and stringers (less material but more expensive due to the use of more concrete and reinforcement

  • Foundations on piles or wells (for foundations that are too deep)
