Recommended Waterproofing Services For Ajax Homes
What The Age Of Your Foundation Says About Your Waterproofing Service
- Homes Built Pre-1970: Making up approx 12.5% of Ajax homes, foundations are likely to be concrete block or older stone/rubble (especially pre-1945), which are highly susceptible to water seepage through mortar joints. Recommended services: Exterior Waterproofing and Foundation Crack Repair.
- Homes Built 1971–1990: Approx. 32.2% of Ajax homes, foundations are more likely to be poured concrete, but the quality of original drainage and exterior waterproofing may be failing due to age. Recommended services: Exterior Waterproofing, Foundation Crack Injection, and Interior Drainage/Sump Pump Systems.
- Homes Built Post-1991: Approx 41.1% of Ajax homes, foundations are primarily poured concrete. Vulnerabilities are less about the material and more about urban flooding from heavy rain overwhelming sewer/storm drains. Recommended services: Interior Waterproofing (Trenching), Sump Pump Installation, and Backwater Valve Installation.

Basement Waterproofing Rebates In Ajax
Save Money On Your Water Damage Protection Services!
Due to the City of Ajax’s growing concern about flooding, the government has started offering waterproofing rebates to protect private properties throughout the city.
The Durham Region Loan Program provides residents of Ajax with an interest-free 3-year loan for up to $3,000 for the installation of flood protection devices like a backwater valve or sump pump.
- A backwater valve is crucial for protection against sewer backup – a common issue in high-risk, urban areas like Ajax.
- A sump pump is essential for managing groundwater and weeping tile drainage to prevent hydrostatic pressure from cracking the foundation.
For more information and application forms, see The Durham Region Loan Program here. For assistance with your application, call DGI! Our local waterproofing contractors can help you navigate the process.
