What customers like the most about Level IT Foundation Repair and Waterproofing is that it conducts thorough inspections to determine the root causes of water leaks. At least, that’s what reviews such as these have said:

“We had some questions about a crack and leak in our foundation, Mariano arrived and talked us through our concerns. He was very knowledgable and helped us assess not only the concerning areas but around the entire house. When he left we had a good idea of what actually needed to be done and we were very pleased. Great to see a company assessing if something actually needs to be done instead of doing the work anyways just to get a profit. Thanks so much!!”—Alicia Yaremko

“We had a leak in our basement where we discovered this had happened before, prior to us owning the house. The previous home owner’s fix had now failed and we needed a sure-fire solution to ensure this wasn’t going to happen again.  Unsure of how to deal with the issue, we ended up speaking with many different companies for possible solutions. Of the many people we talked to, Level IT (Mariano) was the only one that spent a great deal of time with us explaining the issues, causes, and how to correct it. He made sure we understood the scenario 100%, which gave us great confidence to go ahead with them. Their workmanship and tidy jobsite after Day 1 had me thankful we hired them. Never had we had a contractor tidy up their space like they did. No joke, brought a tear to my eye because I was so impressed with their work ethic. Everyone on their team (Mariano, Maximus, Cormack, Lisa etc.) were professional, diligent, fair, and thorough, ensuring we were completely satisfied with the job. Highly recommend you use Level IT for your foundation work.”—Chant Hew

Exterior Waterproofing vs Interior Waterproofing

In general, there are two types of waterproofing methodsinterior waterproofing and exterior waterproofing.

Interior Waterproofing

For interior waterproofing, you’re simply rerouting the leaking water outside of the house. This technique usually involves the use of coatings and sealants to repair cracks on your foundation.

Installing sump pumps to pump out the water flowing inside is also an interior waterproofing method. Waterproof paint is also beneficial.

Before installing and applying any of these waterproofing techniques, you’d need to find the source of water and moisture.

Exterior Waterproofing

On the other hand, exterior waterproofing is a method that focuses on blocking water and preventing leaks altogether. This method is a combination of eavestroughs, gutters, french drains, and drain tiles that’ll carry water away from your house’s foundations.

By keeping water away, exterior waterproofing thus keeps the foundations dry. It thus prevents any damages and leaks.

So, if you ask us, we would definitely choose the exterior waterproofing method as it really keeps water away instead of just controlling the water that comes in. But do know, this option is costly.

However, if you already have existing sump pumps and are simply thinking of upgrading their capacity, then you can still stick to your interior waterproofing plan.

Drainage solutions

You can also use drainage solutions, such as a dry well installation, to prevent water from seeping into your foundations.

Causes of Basement Flooding

It’s also important to understand how homes acquire water damage. Here are the different causes of basement flooding that you should watch out for:

  • Surface water runoff
  • Groundwater swelling
  • Drainage failure
  • Broken or clogged pipes
  • Improperly installed downspouts, gutters, and pipes
