Basement Underpinning/ Lowering Toronto

Basement underpinning is one of the few investments with the highest returns for any homeowner. This home improvement project helps you to convert your crawl space or an impractical basement to a functional, livable space.

This can be used by homeowners as an additional living space or could be rented out as a separate unit and would thus be a potential source of income. Whether you decide to use it for your own needs or rent it out, it can definitely increase the market value of your home.

Basement Underpinning/Lowering Toronto

Most frequently, basement underpinning can be carried out at properties with insufficient headroom. The process of basement underpinning is basically the lowering of the basement to increase the height of the basement’s ceiling. With this it becomes more airy and has more light which makes it livable and adds a great additional space for your home. It is a highly complex task and requires expertise. But if it is done properly, it can be completed with minimum disruption to the homeowners. We have basement underpinning specialists at Concrete Master. Our team has carefully devised a multi stage process and will take care of all details during each stage of the project.


Before starting the process, we will present you with a detailed plan of new floors and structural modifications involved. We will engage an engineer and an architect at the planning phase so that they can properly plan your new space and get necessary permits to begin the work. Underpinning process involves moving and extending the load bearing walls under the house, therefore it is important that we fulfill the legal requirement and get the right permits and municipal approvals prior to starting the process. Please note that no project will be carried out without the required permits and stamped architectural/engineering drawings.


After obtaining the necessary permits, preparations are made for the actual underpinning job. This involves rerouting of the connections to your furnace so that heating pipes are not affected in the process. In order to prevent disruption and damage, the existing plumbing and wiring has to be rerouted as well. Temporary support structures such as vertical jacks have to be installed to ensure that the structure of the house remains stable during the basement underpinning construction. First step is to remove the existing concrete floor and excavate the soil to a certain required level.


Next step is the underpinning process. The perimeter of the basement is divided into 3 equal sections. Then, each section is dug out and filled with concrete one by one. During the process a two inch gap is left between the newly poured concrete and original foundation which is filled with non-shrink grout. The process is repeated for all three sections. Once your new foundation walls are in place, you can remove your old plumbing and replace it with new plumbing. The new plumbing rough-ins will help you in creating your desired space. We will then install a basement waterproofing system to ensure that your basement stays dry, this may include internal weeping tiles, waterproofing membrane and sump pump. Then, we will place six inches of gravel throughout the basement and pour in the new concrete floor evenly on it. Once the concrete is dry your basement is ready.
