iHow this is made

This summary is generated from the verified data on this profile: services, service area, credentials, warranty terms and the company's Google review record. It is reviewed by an editor before publishing and refreshed whenever the underlying data changes. Nothing here is asserted that is not stated elsewhere on this page.

Editorial Standards

Groundworks Foundation Repair Calgary works out of a branch at 5555 80 Avenue SE in the Great Plains area, and its crews handle basement waterproofing, foundation repair, crawl space repair, concrete lifting and radon mitigation. The company says Calgary's expansive clay soils and freeze-thaw cycles put heavy pressure on foundations, which is the problem most of its waterproofing work starts from. Interior drainage, sump pumps, wall vapor barriers and dehumidifiers are part of the basement line, and quotes and financing options come out of a free inspection. Hours run from 5 am to 9 pm on weekdays, 6 am to 9 pm on Saturday and 8 am to 9 pm on Sunday. Groundworks Foundation Repair Calgary holds 4.8 from 890 Google reviews, read October 20, 2026, and reviewers repeatedly praise clean job sites and crews that explain each step.

Editorial Review

Our Take on Groundworks Foundation Repair Calgary

Groundworks Foundation Repair Calgary pairs a large review base with a service mix that fits Calgary's clay and freeze-thaw conditions. Crews are praised by name for tidy work and clear explanations. The trade-off is that it is a branch of a larger company, and warranty terms are not spelled out online.

    Exceeded expectations. Tasks were to lifted and and level 65 year old concrete side walk; lift apron concrete to meet front steps to the home which had sunk about 4 inches making the last step down 4 inches too high and a hazard. Patch cracks in oversized driveway. Leah who was the foreman was communicative throughout and the work was completed at the estimated cost. It was tiny favourite part of renovations to the property. Leah gets ⭐️⭐️⭐️⭐️⭐️ !! DZ Edmonton AB

    Absolutely disgusting experience with the call assistant, she wasn’t able to explain the appointment system, was very rude and dropped the phone. Wouldn’t come back for sure

  • Denise LeBlanc5.0

    I recently had Laven and Oluwatosin here from Groundworks to install a weeping tile system to replace mine that failed. The pre-install inspection was so thorough as was the explanation of system and how it works after completion. Took less time than originally expected, both were punctual and called ahead, respectful of my home with thorough clean up afterwards. Certainly gives me peace of mind should we ever have another record rainfall event, hopefully not. Groundworks is lucky to have Laven and Tosin and I'd recommend them and Groundworks. Thank you Denise 😊

    We had Groundworks complete our interior weeping tile this week, and the entire experience was honestly excellent from start to finish. Denis was wonderful to work with during the estimate and planning process. He was knowledgeable, straightforward, and gave us very competitive pricing. They were also able to get us booked in sooner than we expected, which was a huge bonus. Groundworks also manages and services our sump pump, so having one company we trust to look after both the sump pump and weeping tile gives us a lot of peace of mind. The work itself for the interior weeping tile took two days, and Walter and Alexander were fantastic. They were kind, respectful, communicative, and incredibly mindful of our home throughout the process. The work involved them being inside and Walter and Alexander kept everything pristine and made the interruption to our day as minimal as possible. You could tell they genuinely respected our home and wanted to do things properly. It is not often that a major home repair feels this smooth and well managed. We really appreciated the professionalism, attention to detail, and care from everyone involved. I would absolutely recommend Groundworks to anyone needing this type of work done.

    We have had exceptional service with Groundworks Calgary for many years. We just had the foundation for our front steps reinforced. What a difference this has made. We were pleased with the whole process. From the time of the inspection and estimate and then with Yughurtha and Abdi who performed the work. They were excellent!

Company Background

About Groundworks Foundation Repair Calgary

Calgary's expansive clay soil swells when it is wet and shrinks when it dries, and winter frost heave adds another round of pressure on foundation walls. Groundworks Foundation Repair Calgary builds its basement and foundation work around that problem. The branch operates from 5555 80 Avenue SE in the Great Plains area, with Mike Aasen listed as general manager, and it serves Calgary, Cochrane, Lethbridge, Medicine Hat and other southern Alberta towns.

Waterproofing here means interior drainage, sump pumps, wall vapor barriers and basement dehumidifiers, plus a product the site calls FreezeGuard. The company also repairs foundation cracks and walls, stabilizes crawl spaces, lifts sunken concrete and installs radon mitigation. Its site says the Alberta operation grew out of Clarke Basement Authority, PolyLevel Alberta Corp. and Doug Lacey's Basement Authority of Calgary, and that the team is employee-owned. It cites more than 30 years of experience, but no founding year for the Calgary branch.

Reviewers give the clearest picture of how jobs go. One homeowner credits Tosin and Leonid with reworking a basement that had three sump pumps and cutting it to two. Another names Oleksandr, Daniel and Yevgen for breaking out a concrete slab, handling surprises under it, and walking through a final review. A third praises Chris for acting as the single point of contact on a multi-trade job. Not everything is smooth, since one crew ran into unexpected conditions under the slab, though the reviewer said they were dealt with. Groundworks Foundation Repair Calgary has 4.8 from 890 Google reviews, read October 20, 2026.

This company suits homeowners who want one contractor for water, cracks and radon in the same visit, and who like a free inspection before any price. It suits less well anyone who wants a small owner-run shop, since this is a branch of a larger Canadian company. Alberta has no trade-specific waterproofing licence, so ask about business licensing and permits instead. Before booking, ask what the written warranty covers and whether it transfers to a buyer, get the scope and price in writing, and check the business through the City of Calgary business licence and building permit lookup, Alberta Safety Codes permits, and Alberta Consumer Protection business licensing.
