What Causes Basement Wall Cracks?

Why you Need Basement Crack Repair?

The basement, because of its below-grade position, is vulnerable to water seepage. Statistics show that 90% of basements will eventually leak for various reasons, such as:

Foundation cracks, form tie holes, blocked weeping tiles, drain back up and e.c. Water seepage will cause substantial damage to the house if not addressed in time.

The extra moisture encourages the growth of mold and fungus, which can cause serious health concerns.

Additionally, the structure of the entire house is at risk. This is why proper waterproofing of the basement is essential – the sooner the better.

Are Basement Leaks Common in Toronto & GTA?

Major Concern for the New Home Owners

Did you know that basement leaks are the leading, major complaint from new homeowners?

According to Tarion Ontario New Home Warranty Program, if you signed an Agreement of Purchase and Sale for a new home and gave your builder a deposit, Tarion’s two year warranty program protects against water penetration through the basement or foundation walls.


High-quality basement waterproofing plays a crucial role in protecting your property. Nowadays, foundation waterproofing in new houses is done during construction. However, tar is still used as a foundation sealant, and this is wrong. Tar rates as damp proofing, not waterproofing, and will fail eventually.

We use only high-quality materials like Aqua-Bloc, Blueskin WP-200, and DELTA MS and we take the time that is required to provide you with the best possible result. When it’s done by Aquamaster it is done right. All our work comes with 25-year warranty which is transferable to subsequent owners.

Whether it’s a basement leak, drain or plumbing issue, contact us today and schedule a free, no-obligation assessment. Our experts will diagnose the problem and provide you with efficient solutions at the most affordable prices.

What Our Clients Say?


Stephanie G.

Residential Client

I used Aquamaster for two separate home waterproofing projects and I was extremely satasified with their work and price. Their team are highly skilled, thorough and were able to complete the 10.5 hour job in one day. They were even kind enough to seal my window frame after I noticed a minor leak. I would highly recommend Aquamaster for all your waterproofing and plumbing needs.

The Aquamaster team is absolutely fantastic! They went above and beyond to diagnose and correct the problem that I had with my basement plumbing caused by old pipes and persistent tree roots. I used them once in 2012 and in 2020. I cannot say enough good things about this team - Highly recommend.

Aqua Master quoted me a very fair price for waterproofing and finshed the job ahead of schedule. We haven't had any water issues in our post-war hm since then. Highly recommend this business for its professionalism and quality of work. Hire with confidence!
