Basement Underpinning Toronto

Eliminate foundation concerns and embrace structural integrity with our specialized underpinning services. Secure your home’s base, unlocking the potential for expanded living spaces and increased property value.

What is Basement Underpinning?

Basement Underpinning – the process of strengthening and stabilizing basement foundations, which is used for older buildings built on problematic soils or those that have started to crack over time, by removing the soil and installing new supports under the foundation.

Thus, thanks to the underpinned basement, you:

  • Increase the value of the property.
  • Increase the durability of the house.
  • Create a dry and comfortable space in the basement.
  • Protect your house from structural damage caused by groundwater.

If you’re thinking about basement underpinning in Toronto, consult with the qualified professionals at Quality Age Build. We will assess your needs and recommend the best course of action.

Understanding Basement Lowering

Basement Underpinning and Basement Lowering are two different but important processes that aim to improve a home in different ways.

Basement Lowering can transform a basement into a functional space. Instead of storing things or junk in it, you can install radiant floor heating, replace outdated plumbing, make repairs, and get:

  • A gym.
  • A room for games.
  • An entertainment area.
  • Office space.
  • An additional cozy room.

How does the Basement lowering process work? To do this, specialists remove excess soil underneath by making an excavation. This allows them to create a support level lower than the existing footings and then add new foundation walls, concrete floors, and concrete slabs and pour concrete. The piers, in particular, provide support for the new foundation, ensuring stability and preventing further subsidence.

Advantages of Choosing Our Basement Lowering

Many homeowners are unaware of the numerous benefits of basement lowering Toronto, so they don’t think about the opportunities it can open up for them. Here are just a few of the main benefits you can expect if you choose our services.

Increased Living Space

Gain additional square footage to create new rooms to suit your needs. Set up a home office where you can work productively from the comfort of your own home, add a room where guests can stay comfortably during visits, or increase storage space by creating an additional pantry or dressing room. Anything is possible!

Enhanced Property Value

Getting more living space makes your home more competitive in the property market. Potential buyers are willing to pay more for homes with more rooms and more usable space. What’s more, an increase in the market value of your home is a strong argument for a loan or mortgage.

Improved Basement Height

Completion of the basement lowering process ultimately gives you a feeling of freedom and comfort due to the increased distance from the concrete floors to the ceiling. So forget about cramped and limited space! Instead, the visual perception of the room is significantly improved, making it more spacious and bright.

Better Moisture Control

Lowering the basement significantly improves ventilation, which leads to lower humidity levels. This, in turn, creates a healthier microclimate, prevents the formation of mold and mildew, and makes the basement more comfortable, making it suitable for creating livable space, recreation areas, or offices.

Increased Natural Light

Thanks to Toronto Basement lowering, it becomes possible to install larger windows, which gives more natural light. This makes the basement floor both more cozy and saves energy, as the need for artificial lighting is significantly reduced during the day. Plus, natural light has a positive effect on mood, reducing stress and anxiety.

Energy Efficiency

Better insulation and natural light combine to reduce energy costs. As the basement is lowered in Toronto, the area for thermal insulation increases. This leads to less heat exchange with the ground, which in turn reduces heating costs in winter. It also creates the opportunity to install radiant floor heating, which is one of the most efficient and cost-effective heating methods.

Customizable Design Options

With a renovated space, you have a chance to create it from scratch, carefully considering functionality, style, and design. Let your imagination run wild and create a space that is not only practical but also unique, reflecting your personal touch.

Utilizing Your Basement After Lowering

As we’ve already mentioned, implementing underpinning projects can transform it from a simple warehouse space into something much more. Here are some ideas on how you can use your renovated space.

Wine cellar

Many people dream of having a comelier’s corner where they can store their wine collection and taste it with friends. Unfortunately, there is often not enough space to make this dream come true. The basement can be the perfect place for this.

However, you will need to obtain permits and licenses and make sure that the basement complies with building and fire safety regulations.

Why is Basement Underpinning Important?

Only some people consider the basement an additional living room or a relaxing space. Usually, it’s used as storage for rarely used items. This is typically due to limited space, the absence of windows, and low ceilings. In such cases, the underpinning Toronto cost can be well justified because it provides an additional room without the need for expensive additions!

One of the primary building standards for a house is an 8-inch foundation thickness. When looking at an unfinished basement, it may seem like the space is quite roomy. Yet, when you consider the installation of the ceiling, floors, and various mechanical systems, the room shrinks significantly. Of course, raising the above-ground structure, which is the house, is not feasible without massive investment. Therefore, an alternative option is lowering the basement. It is essential to hire competent professionals to execute basement lowering projects according to standards to avoid costly revisions, saving money and stress.

Our Basement Underpinning Process

We understand how labor-intensive and challenging the basement reinforcement process can be, not to mention the required skills and knowledge. That’s why such work should be done exclusively by competent and experienced specialists. To perform basement underpinning in Toronto, it’s not enough to simply deepen the existing floor in the basement, as this can pose a risk of damaging the existing structure. Qualified professionals know that it’s necessary to excavate space for the foundation and create a new one beneath the existing one. This kind of construction can support the overall weight of the building.

Our company’s professionals first thoroughly analyze the foundation and the surrounding areas. This allows us to determine construction standards and the requirements for the work. It’s very important at the start of the process to understand how much depth is permissible for this specific basement area, the sequence of plumbing and repair work, and whether a change in the location of electrical wiring is possible.

Do you want to have a better understanding of the step-by-step process? We’ll be happy to explain it to you below!

Clearing the Space

Often, the potential of basement spaces in Toronto homes is not fully utilized by their residents. Low ceilings are often to blame, making basements suitable only for storing rarely used items. Thanks to Toronto underpinning, the basement can be transformed into an additional fully functional space. The work begins with clearing out all belongings and then demolishing walls, floors, and finishes. This is necessary to prepare the space for contractors since a cleared area provides a better view of the layout and ways to modify it.

Strengthening Basement Sections

Once you have architectural drawings and permits from city authorities, your basement will be conditionally divided into vertical sections, usually labeled 1, 2, 3, and 4. These sections indicate the areas that need to be excavated. These sections form the structure of the basement’s foundation. After these sections meet the standard, they are filled with concrete at the agreed-upon lowered level.

Excavation of Soil

After removing the concrete slabs from the basement, soil excavation beneath the foundation begins. This increases the basement’s height, implying a substantial amount of work that likely requires special equipment. To efficiently remove excavated soil from the basement, belt conveyors or wheelbarrows can be used. The choice of soil removal method depends on access to the basement.

Demolition of the Concrete Floor

Transforming the basement requires the removal of existing concrete structures. It’s no secret that the demolition of such structures is a laborious and meticulous process. The most challenging part is removing concrete slabs – for this, professionals first need to identify the utilities’ locations and measure the existing floor’s thickness. Additional equipment may be required to facilitate the demolition process if it’s more than 4 inches thick or reinforced. The thickness and type of reinforcement can be determined from the broken edges.

Interim Inspection

Conducting inspections at each stage of the work is crucial to prevent threats to the overall building’s integrity. The integrity of the walls or load-bearing columns is vital for the successful outcome of the basement underpinning Toronto process. To guarantee compliance with basement lowering standards, a licensed engineer or city inspector signs off on the completion of the work. We collaborate closely with licensed engineers who perform regular inspections at each stage. So, you can rest assured that the work is carried out in accordance with the approved project and established standards.

Installation of Drainage System

You probably know that basements are more prone to water accumulation than any other part of the house. Therefore, after laying the foundation, it’s necessary to install a robust and reliable drainage system. After discussing all possible details and options with you, we will connect new drains and ensure they function as intended by testing their ability to drain under pressure. This allows us to ensure that there are no potential leaks and that all plumbing connections work as they should.

Installation of Waterproofing Systems

Water leaks from below ground level are just one of the problems you need to address. Groundwater and rainwater can also seep from below the ground, causing damage to the integrity of your basement. Waterproofing is the next step to combat water leaks. Before backfilling with gravel over the soil, our team installs a waterproof delta foundation, ensuring you never have to deal with water leakage problems in the basement.

Installation of Insulation Systems and Warm Floor

Since the basement is literally «underground», sunlight does not reach it, making it constantly damp and cold, not to mention the concrete slabs that form the basis of the floor. An excellent solution for improving the basement is the installation of warm floors, which will spread warmth to other parts of the space. What does this give you? At the very least, you can finally forget about humidity problems and, as a result, the appearance of dangerous mold in the basement.

Installation of Sump Pump and Sump Pit

Due to heavy rainfall, the city’s drainage infrastructure may struggle to handle the volume of stormwater, which can lead to flooding and basement inundation. To prevent this, it is recommended to dig a sump pit and install a sump pump before pouring the concrete floor slabs.

Final Pouring of the Basement Concrete Floor

Once all plumbing and electrical systems are installed, our specialists pour concrete. Beneath the concrete is a layer of gravel, covered with a sheet of waterproofing to prevent moisture from reaching the floor slab. Then, any defects in the slab are corrected using leveling, followed by cleaning and the final cleanup of the space.

Increasing Your Home’s Strength

Learn More

Before lowering the basement, all load-bearing structures are removed, and the concrete floor is dismantled. This allows you, together with the experts from Quality Age Building, to determine whether the foundation of your home was correctly laid and whether it has sustained any damage due to climate changes, repairs, or wear and tear. Identifying such issues allows for their rectification, thereby strengthening the structural integrity of your home. This way, you can ensure the safety of your family.

The cost of basement underpinning per square foot$80
The cost of excavation (per linear foot)$450
The cost of drawings and building permitfrom $2,500 to $4,500

Factors Influencing the Cost

1. The area and linear footage of the unstable foundation

As the size of the basement increases, so do the costs of the basement underpinning Toronto. This is due to:

  • The need for more materials such as bricks, concrete, rebar, and waterproofing.
  • More work, including digging, installation of support structures, the area to be poured with concrete, and finishing.

In addition to the total area, it is critical to take into account the linear meters of non-load-bearing and load-bearing walls that need to be supported. This affects the number of concrete footers, columns, or posts, as well as the complexity and cost of the concrete work and the overall basement underpinning.

2. Accessibility for excavation

Limited access to the exterior of the house significantly increases the cost of Toronto underpinning due to the difficulty of hand digging, the need for special equipment, and the difficulty of removing debris.

3. Soil type

Soil that is difficult to dig, such as rocky or clay, requires more time and effort, which can lead to structural problems. Wet soil, prone to flooding or with a high water table, requires installing waterproofing and an additional drainage system. All this increases the cost of basement underpinning.

Therefore, it is important to conduct a soil composition analysis on your site before starting a basement underpinning Toronto project to take into account all potential costs of solving foundation issues.

4. Equipment required and amount of manual work

The choice of equipment has a significant impact on the overall cost of basement underpinning projects. In general, there are two types of equipment:

  • Standard: shovels, picks.
  • Special: hydraulic jacks, excavators, drilling rigs.

Standard equipment is cheaper but requires more manual labor, which leads to higher labor costs. Special equipment significantly speeds up the underpinning project saves time and money, but renting or buying it can significantly increase the total cost of basement underpinning.

6. Condition of the foundation

The condition of the foundation has a significant impact on the cost of the Underpinning in Toronto project. A damaged, old, or poor-quality foundation will require additional foundation repairs, reinforcement, or replacement, which will significantly increase the overall cost.

Therefore, it is recommended that you thoroughly assess the condition of your home’s foundation before you begin to take into account all potential costs in the basement underpinning process.

5. Availability of water

If the basement space is prone to flooding, you will need an additional weeping tile system, drainage systems, and pumps, which will significantly increase the total cost of the basement underpinning project. High groundwater levels also complicate basement underpinning works and require additional measures to protect the foundation from moisture.

Even high humidity in the basement can indicate problems with the waterproofing system that need to be addressed before starting basement underpinning work.

8. Location of the object

The cost of underpinning projects can vary depending on the location of the building due to labor availability, competition, local building codes, etc.

For residents of Toronto, structural engineers at Quality Age Build offer favorable prices. We have many years of experience in this region and understand the legal nuances and market conditions.
