Newmarket Basement Waterproofing & Foundation Crack Repair
Historic downtown is the most famous landmark in Newmarket
A wet basement caused by a leaking foundation crack often causes stress and costly damage for Newmarket homeowners. The good news is that most cracks, in poured concrete foundations, can be sealed quickly, effectively, and at a reasonable cost – typically starting around $745 for a standard interior crack injection, in a matter of a few hours.
Since 2002, AquaGuard Injection & Waterproofing® has been helping Newmarket homeowners keep their basements dry with professional Foundation Crack Repair and waterproofing solutions backed by a long-term warranty.
Foundation cracks are common and often found at the corners of basement windows
Basement Crack Repair in Newmarket
Most foundation cracks in Newmarket homes develop because of normal concrete shrinkage during curing or minor foundation settlement over time. The clay soils common throughout Newmarket retain water long after heavy rain and spring snowmelt. When water surrounds the foundation, it finds its way through existing cracks and leaks into the basement. Left unrepaired, even a small crack can allow significant water infiltration and lead to staining, damaged drywall, mould growth, and other costly repairs.
Our team repairs foundation cracks from either the interior or the exterior, depending on your foundation type and the location of the leak.
- Poured concrete foundations – typically repaired from the inside using injected resins.
- Concrete block foundations – repaired from the outside by excavating and waterproofing the foundation wall.
Interior Crack Injection (Poured Concrete Foundations)
For poured concrete foundations, our Foundation Crack Repair process uses high-pressure polyurethane injection to permanently seal leaking cracks from inside the basement. We inject an expanding polyurethane resin into the crack under pressure, allowing it to penetrate the full thickness of the foundation wall. As the resin expands, it fills the crack and creates a long-term waterproof seal that prevents water from entering the basement.
Because the polyurethane travels completely through the wall to the outside, excavation is unnecessary in most situations. The primary exceptions are when a crack is completely inaccessible from inside the basement because it is located behind a fireplace, shower, electrical panel, built-in cabinetry, or another permanent obstruction.

Learn More About Foundation Crack Injection
Many homeowners are surprised to learn that not all foundation crack repairs are performed the same way. The success of a repair depends on correctly identifying the cause of the crack, selecting the appropriate injection material, and ensuring the repair seals the full thickness of the foundation wall.
At AquaGuard Injection & Waterproofing®, we specialize in high-pressure polyurethane foundation crack injection for poured concrete foundations. This method permanently seals most leaking shrinkage and settlement cracks from inside the basement without excavation, making it one of the most effective and economical repair methods available.

Why homeowners in Newmarket choose crack injection
In many instances homeowners are unaware of the presence of cracks in their foundations and many basement leaks are discovered quite by accident.
When homeowners discover a wet carpet in their basement or a puddle of water, they typically want to get the problem fixed as rapidly and as cheaply as possible. The urgent nature of many basement leak repairs and the unplanned maintenance expense make basement crack injections a popular choice for Newmarket homeowners. Most homeowners choose Foundation Crack Repair using polyurethane injection because repairs are completed in just a few hours and typically cost far less than excavation. This allows for the prompt scheduling of crack sealing appointments and keeps repair costs low, as the cost of crack injection is far less than exterior foundation crack repairs requiring excavation.
Exterior Crack Repairs (Block Foundations)
For homes in Newmarket with block foundations, basement wall cracks are repaired from the exterior. This repair involves excavating the affected wall down to the footing, filling the crack with hydraulic cement, applying an elastomeric rubber waterproof coating, and installing a protective membrane to direct water towards the weeping tile. This ensures long-term protection against water entry through the foundation crack.
The only way to effectively seal a leaking concrete block foundation crack is to excavate and waterproof the crack on the outside
