Basement Underpinning

If you are looking to increase the living space within your home, consider a basement underpinning in Toronto with Elite Construction and Renovations. Why move to a new neighbourhood or house with more room when you have the available space under your feet?

Whether you want to be able to use the extra space for a family recreation room, guest quarters, or as potential rental income, we can make your vision come to light! 

As one of the leading underpinning companies in Toronto, Elite Construction and Renovations has the expertise and manpower to ensure all details of this complex process are completed with minimal disruption to your household. 

What Is Basement Underpinning?

Basement underpinning is a way of lowering the basement floor of a house. Using an engineered plan, the structural integrity of the house is kept intact as the floor is excavated deeper into the ground. 

By physically lowering the floor, your home will obtain a larger living space without building an addition on top of the house. This increases the basement ceiling height by opening up the entire underneath to become a larger area of space.

Steps for Basement Underpinning

Underpinning entails several complex steps, all of which require the planning and execution of certified engineers, architects, and skilled labourers. Here at Elite Construction and Renovations, we have the experience, tools, and knowledge to ensure all structural modifications are done properly. 

We work with the homeowner to plan and prepare the site before any demolition work begins. 

Demolition

Before work begins, all portable items are removed. Demolition entails sectioning off portions of the basement to ensure the structural integrity is maintained throughout the underpinning process. 

Each section is demolished one at a time until the proper water drainage is installed. The onsite engineer will mark off which sections should be demolished. The heavy concrete is removed with the use of tools and state-of-the-art equipment that our team members are trained in using. 

Soil Extraction

With extracting the soil, the depth depends on the original planning by the homeowner and the engineer and architect. Lowering the basement can be done several feet beneath the existing foundation floor. 

Inspections

Throughout each underpinning stage, inspections will be done by the qualified team at Elite Construction and Renovations as well as by your city’s building inspectors. Our experts ensure the integrity of the house is not compromised. The various levels of demolition and soil excavation can cause issues if not attended to properly.

Waterproofing

Once the demolition and soil extraction are completed, the focus turns to waterproofing the entire basement. Through age and damage from fluctuating temperatures and environmental elements, the basement is a common place for water to seep in from the ground or leak through the pipes. 

A flood-proof drainage system will be installed and connected to prevent any water issues in the months and years to come. It is an excellent time to have a sump pump system installed in basements where flooding has been an issue in previous years. Testing of the new drains and all plumbing will be performed before work continues with gravel being laid. 

Insulation

One of the big advantages for underpinning a basement is the opportunity to have the new living space properly insulated. While the extra floor space adds more livable area, the basement can have a drafty damp feeling, even with a makeover. 

Adding insulation and underfloor heating, like the popular radiant floor heating system, can improve the living conditions, regardless of the intended room use. A well-heated basement can also help with keeping the floors on the main floor warm.

Laying New Slab

Once the plumbing, electrical, water drainage, and sewer lines are attended to, the next step is laying the new concrete slab. A waterproof liner will protect the concrete from the underlying gravel. The knowledgeable team at Elite Construction and Renovations will ensure the concrete is poured correctly and that it results in a smooth surface that is durable and long-lasting.
