Basement underpinning is the way to change the unusable space of your basement into a livable one. This is done by lowering the basement. If you plan to underpin the basement, here is how it is done. You can read more about the process here budgetreno.ca/basement-underpinning-toronto/
- Demolition Work:
Most of the homes have underutilized basements, because of the low ceiling which can make it feel cramped. The basement is usually used as a storage area. Underpinning will help to transform the space into usable. The process starts by removing all the items from the basement. Following this, the demolition work begins. The existing floors, walls and all other finishes are demolished. The basement is made clear.
- Removal of Concrete Floor:
The transformation begins by removing the existing concrete floors. Removing the concrete floors isn’t easy. If the flooring is more than 4 inches in thickness, power tools are used. The contractor will start by breaking the edge piece or expanding a crack, this will give an idea about the thickness of the floor. It will help to determine the type of reinforcements required.
- Soil Excavation:
After the concrete slab has been removed, the next step is clearing the area by removing the soil. Basement underpinning involves increasing the height of the basement. For that to happen a lot of soil needs to be excavated. The dirt is removed with the help of several methods. The contractor can use a conveyor belt or a wheelbarrow to carry the soil out of the basement.
- Underpinning Sections:
Proper engineering and city-approved drawings will be acquired at this stage. The basement will be divided into verticals. and the sections will be marked as 1,2,3 and 4 over and over again. The number sign towards where the same numbered section would be excavated. It is these sections, that make up for the structural integrity of the underpinning.
- Inspection:
Underpinning needs to be done properly. Otherwise, it can compromise the home’s integrity. Regular inspections are carried out at various stages to ensure that the weight-bearing columns are not compromised. A licensed engineer or city inspection will have to sign off on the work done through the excavation process. It will help you be sure that the basement lowering has been done according to the codes. - Drains:
Basements are prone to water than any other room in the house. This step involves installing a drainage system.
- Waterproofing and Gravel:
Water coming in from the outside is not the only issue. The groundwater can also seep up and cause damage. Hence, it is essential to have proper waterproofing.
- Radiant Floor Heating:
The basement receives very little heat from the sun, and it can be a tad bit expensive to heat it up. One of the best ways to deal with it is by installing an underfloor heating system.
- Concrete Slab:
Once the electrical and sewer lines are in place, it is time to pour the concrete. After that, a screed board is used to smoothen out imperfections. Jitterbug tools are used to bring water, sand and cement to the surface that helps to ensure a smooth concrete surface.
