Basement Waterproofing For Your Leaky Basement? We Can Help!

Recent Post

Leakages over the top of foundation walls can lead to significant issues in your basement, including mold growth, structural damage, and dampness. Identifying these leaks early and addressing them promptly is crucial to maintaining a dry and safe home.

Identifying Leakages

Leakages Over Top of Wall

Leakages at the top of foundation walls can be caused by several factors. Here’s how to assess and identify potential issues:

1. Foundation Grading Issues
  • High Soil Grade: If the soil around your foundation is higher than the foundation itself, it can create pressure that forces water through weak spots between the top of the wall and the sill. Proper grading is essential to ensure water drains away from the foundation.
2. Water Pooling
  • Clogged Drains: Poor grading and clogged drainage systems can cause water to pool around the foundation, leading to leaks.
  • Faulty Downspouts: Incorrectly installed or malfunctioning downspouts can direct water towards the foundation rather than away from it.
  • Defective Structures: Problems with decks, exterior features, or heavy rainfall can exacerbate water pooling issues.

Solutions to Foundation Wall Leaks

Addressing leakages over the top of foundation walls involves several strategies to prevent water ingress and protect your home.

1. Correct Grading
  • Regrade Soil: Adjust the soil around your foundation to ensure it slopes away from the building. This prevents water from accumulating and causing pressure against the foundation walls.

2. Improve Water Drainage
  • Extend Downspouts: Ensure downspouts direct water away from the foundation. Consider installing extensions if necessary.
  • Install Effective Drainage Systems: Create or upgrade drainage systems around your home to redirect water away from the foundation. This may include French drains, sump pumps, or surface drains.

3. Waterproofing Solutions
  • Exterior Waterproofing: Apply waterproof membranes or coatings to the exterior foundation walls to prevent water from seeping through.
  • Interior Waterproofing: Use interior drainage systems and sealants to address any leaks that might occur inside the basement.

4. Repair Foundation Walls and Cracks
  • Crack Repairs: Address any cracks or damage in the foundation walls with professional repair techniques. This includes injecting epoxy or polyurethane to seal cracks and prevent further leakage.
About Us

Why Addressing Foundation Leaks is Essential

Failure to address leaks over the top of foundation walls can lead to:

  • Mold and Mildew Growth: Excess moisture creates an ideal environment for mold and mildew, leading to health hazards and further property damage.
  • Structural Damage: Prolonged exposure to water can weaken the foundation, leading to more serious structural issues.
  • Increased Costs: Unresolved leaks can result in higher repair costs and more extensive damage over time.

I used Aquatech to install a sump pump and do some interior basement water proofing one year ago. When I needed another pump installed, I have called Aquatech again. Crew of two - foreman and another worker arrived promptly, within a week, in time as promised. All work was done promptly and with high degree of quality. Crew was friendly and very diligent. Sump pump performes beautifully and everything was clean and tidy.

I had some increasing leaks in my basement this last rainy season. I got a very reasonable quote from Aquatech as there were about 17ft of area that needed to be addressed. Bob and Vlad arrived bright an early and got to work, they protected all areas of my backyard (gazebo and bbq etc) and got to work. Everything was cleaned up and put back and gravel laid back with my steps and stones leveled back. All repairs completed, and I'm very impressed and would gladly recommend them for your waterproofing needs. Thanks guys !!

Excellent execution just as promised. Alex and Alex finished our project very quickly and neatly. We couldn't even tell that they were there. All aspects of the contract were observed, professional and prompt communication and customer service. Price was not the cheapest nor the highest, but considering the importance of this operation, we didn't want to choose just a random person. Overall, we were very satisfied and highly recommend Aquatech.

I highly recommend AquaTech Waterproofing!! They do excellent work! It was a pleasure dealing with the company, right from obtaining the quote from Shawn, to the team doing the work. Shawn listened to all of my concerns about water leakage, offered solutions, & quoted a very fair price to resolve the problem. The men doing the repairs (Eugene and Michael) were very polite to deal with, hardworking, & left everything looking good & very tidy, as mentioned on the company website.

AquaTech was referred to me by my sister. She had need of their services 2 years ago & had experienced the same quality workmanship & customer service I received.

The repairs Aquatech made will give me peace of mind that I won't be experiencing flooding in my basement any longer!

I recently had Aquatech Waterproofing come by to assess a flooding issue in my basement, and I was truly impressed by their honesty and professionalism.

Shawn, the technician who came to my home, could have easily given me an expensive quote to re-dig and reinstall the drain and window well. Instead, he gave me an honest and straightforward diagnosis — explaining that the real issue was grading around my home. He told me that with proper water management and redirecting the downspouts, the flooding problem would resolve itself.

That level of integrity and expertise is rare and admirable. Because of this experience, I would trust Aquatech completely for any waterproofing work in the future. If you’re looking for a company that values honesty, customer trust, and real solutions over just making a sale, Aquatech is the one.

We live in an older house and our basement started to leak every time it rained. We were worried about mold build up on the drywall and how it would impact the foundation, so we reached out to a few companies for quotes. Aquatech was friendly, had great reviews, and gave us the best price! They were professional, worked quickly, and were able to complete the entire sump pump installation and waterproof our entire basement in 1 day. I would highly recommend this company to anyone looking to waterproof their basement!

After a leak in our basement we found that we had 7 cracks in our poured foundation, several of which had started leaking. Shawn came out promptly to assess the situation and the work that was needed. He provided a quote quickly. Once we were ready to go ahead with the work, he was able to have a team start reasonably fast. The guys worked long - sometimes nearly 12 hour days. It took 7 days to have the house completely waterproofed on all three sides and completely replaced the drainage at the footing and the window wells. The guys were courteous and friendly, cleaned up after themselves and didn’t disturb our neighbours. Should we find ourselves in a home requiring waterproofing again, I wouldn’t hesitate to reach out to Aquatech again. Thank you!

I enjoyed the sales process with Shawn. It was easy to work with him and he gave me a fairly priced quote. The crew on site were efficient, organized and left the property clean.

AquaTech was the only company that returned my calls in a timely fashion when I had a crawlspace flood recently. They came and did the waterproofing work, and kept me informed during the process. They were very accommodating, and great at proposing solutions when problems arose. Everything looks tidy and professionally done. I would recommend AquaTech for any waterproofing work.

I recently used Aquatech to do interior waterproofing of our basement. I could not be happier with their service. The sales process was very professional with a no-pressure approach and the salesman, Eugene, worked with me to fit within our budget. He was extremely responsive to questions as well. The construction crew, led by Slava, were very professional and polite. They made a mess and it was bad since it had rained very hard on them while they worked. They did not complain and cleaned up my basement so it was spotless - I didn't have to tell them to do this! Their work was very good and could not be happier! I highly recommend using Aquatech.

Terry is very knowledgeable and provides all options with full and detailed explanation. I even asked for drawings (as I’m very visual) and he enthusiastically did it for me. You feel confident he is looking after your best interest. He also explained how I can do some additional things myself to improve water drainage on the outside and save money. The work was fairly prized and professionally done. Alex and Yevhen were friendly and worked fast, clean and efficiently.

Waterproofed! Took a bit to get a date sorted because of how busy they were, but got a date within 3 weeks of our consultation. Luckily we weren’t in an emergency type of rush. Great price and even better work!

Absolutely thrilled with the job these guys completed on our 74 year old home in Hamilton! It was a HUGE undertaking and they did it in 3 days! These men work very hard and leave the place spotless until they come back the next day! Some evenings they were here until 9 pm! They were polite, respectful and extremely neat!!! Our sales rep Richard was very professional and extremely knowledgeable in the field! He listened and executed the work we asked for! We highly recommend them and their final price was fair and reasonable for the thorough job they did! We welcome a dry basement finally! Now we can start planing for those renovations and a new cosy basement for grandchildren!!!! Thank you for the great job!!!

Had the basement done from the inside, with the few recent heavy rain storms combined with a damp ground. Everything worked well, the sump pump kicked in and dispersed the water out of the house as planned and designed.
The pump isn’t loud, they also completed the city of Toronto sump pump rebate for me.
When the crew was here I requested a longer discharged pipe outside from the house and they accommodated with no problems.
The pricing was slightly better than the other 3 quotes I received.
Terry did an excellent job communicating and answering any concerns I had after the job was completed.

Aquatech was wonderful right from the first contact to having Richard come out and give us a very complete and detailed quote to the two man crew who were here exactly on time and completed the day hours ahead of time. All the locates were taken care of and within a week of contacting them the job was completed. The workman did a fabulous job and were very respectful of our property. They reviewed the scope of the work before they started and asked if we had any questions. When the work was complete it was difficult to see where they had worked and dug the trench. Everything was tidier than before they started. We are very impressed and in a world where household repair companies can be less than favourable, Aquatech stands head and shoulders above any of them. We would highly recommend this company. We also have a life time transferable warranty too. Bravo. We will definitely be telling all the people we know about our wonderful experience. Thank you.

We had a flood disaster the day after we got the keys for our new home. Aquatech Waterproofing responded to my request for help quickly and came to access the damages the same day. They gave us several options for repairs as well as prevention that were fairly priced and a quick turnaround time. They executed our chosen plan quickly and did a beautiful job. They have been very responsive, answering questions about the products we chose and we recommend them to anyone that needs quality work done in a timely manner. Very compassionate and empathetic for our situation as well.

EXCELLENT experience. Andrew was the first one to arrive and was extremely kind and helpful. Igor and Basil joined Andrew a few minutes later and all three of them worked very hard and finished this massive job in one day. These are some of the hardest workers I have ever seen. There were no hassles or surprises and Andrew, Igor and Basil were very skilled and courteous. Also, Nico was VERY flexible with our constant changes of plans and was very accommodating and understanding. An excellent experience all around - could not recommend more highly!

Much thanks & appreciation to Slava & his hardworking crew for their excellent job excavating, installing weeping tiles & pipe, repairing cracks, waterproofing, and backfilling the 7'-deep trench 27' along the full side of our home.
