Can I live in my home during basement slab replacement?

In most cases, yes, but access to the basement will be limited. Keep in mind there will be some noise, dust, and other temporary disruptions. So, if you prefer a quieter, more peaceful space, it might be a good idea to stay elsewhere while the work is underway.

Will a new basement slab help with moisture issues?

Absolutely. We always replace the old basement slab with a new, more durable one that’s properly installed and sealed. This significantly improves moisture control and drainage. If requested, our team can also add interior basement waterproofing for long-term protection against leaks and dampness.

Are any permits required for basement slab replacement in Ontario?

Yes, basement floor replacement needs to follow local building codes and requires the right permits to meet Ontario standards. But there’s no need to worry — our team has years of experience handling this and takes care of all the paperwork for you.

When and Why You Need a Basement Slab Replacement

A slab basement is a type of foundation where a solid concrete slab is poured directly onto the ground. This slab supports your entire home, providing strength and stability. Over time, its integrity can be affected by things like:

Moisture
Settlement
Structural damage, and more.

When basement slabs become damaged, they need to be replaced; otherwise, they become a threat to the strength and stability of your whole home. Basement slab replacement involves removing the old slab and installing a new one to restore your basement’s function and durability.

Benefits of Basement Slab Replacement Services in Toronto

If you want to boost the safety, value, and comfort of your Toronto home, basement slab replacement services are an excellent choice. Give your lower level a fresh start and enjoy:

Enhanced Structural Integrity

A new, solid basement slab strengthens your foundation and helps prevent future settling or cracking.

Better Moisture Control

Old slabs can let moisture seep in. A new, well-sealed slab protects your basement from leaks and mold.

Lower Future Repair Costs

On-time basement slab replacement can help you avoid bigger repairs down the road, saving both money and hassle.

Peace of Mind

With a solid, secure basement floor, you’ve got one less thing to stress about, especially with the Toronto lifestyle.

Common Methods for Basement Slab Replacement in Toronto

At first glance, all concrete basement floors in Toronto homes might look the same, but they’re not. Every basement slab is unique, with its own size, age, condition, and structural details. That’s why our team takes a tailored approach to every basement slab replacement. Here are the most common methods we use:

Full Slab Removal and Replacement

We fully break up and remove the existing concrete slab, then excavate the soil beneath it to prepare for a new foundation. This lets us fix any issues with the subsoil or drainage and properly compact the base using crushed stone or gravel. A vapour barrier (polyethylene sheet) is laid over the prepared ground before pouring a new concrete slab.

Adding a New Slab Over an Existing Slab

In some cases, removing the existing slab isn’t an option due to ceiling height or structural limitations. In this case, we pour a new slab over the old one, including the installation of a vapour barrier. This method can help improve floor evenness, but may raise the overall height and cover existing structural elements.

Slab Levelling and Repair

Sometimes your concrete basement floor just needs repair. We often use polyurethane foam or cement-based grout for this: the expanding material is injected under the slab to lift and stabilize areas that have settled or cracked. To fill concrete cracks, we typically use epoxy resin, which helps restore the structural integrity effectively.

Check out our recent projects and see that our experience speaks for itself. We perform each underpinning and waterproofing with the utmost care and attention to details.
