Commercial Waterproofing Experience

Toronto is a mix of historic buildings and new builds; however, both are susceptible to a catastrophic leak. Historic buildings in the core are especially at risk due to poor waterproofing technology. Waterproofing measures in the 1800s and at the turn of the 19th usually consisted of tar and no Bituthene membrane, which can wreak havoc on the structural integrity of the building over time if it has suffered numerous leaks. An exterior waterproofing solution, consisting of an excavation, and the installation of a Bituthene membrane and a weeping tile is the proven solution to preserving your commercial property as well preserve its value if you sell in the future. This is because real estate agents can identify past water damage and potential buyers will shy away, potentially forcing you to sell under your listing because the property will be seen as a liability.

City Wide Group is the GTA’s premier commercial waterproofing specialties for buildings of all sizes. Owners and managers of strip malls/plazas, institutions (hospitals, retirement homes, etc), historic commercial buildings (banks, churches, energy buildings), and retail spaces have relied on City Wide Group for decades and can service your property too in a timely and professional manner.

  • Before any digging gets underway, The City Wide Group ensures all utility services are informed and the dig site is clearly marked.

  • We first reveal the foundation’s walls and base, giving them a good clean to guarantee that the new concrete will bond well.

  • To deal with any cracks or openings in the foundation, we fill them with a specific type of cement before applying a fresh concrete layer over the entire area.

  • We then secure the foundation with a RUBBER BITUTHANE MEMBRANE for waterproofing, covering both the wall and its base.

  • Additionally, we attach a DELTA MS plastic mat along the foundation wall down to the base, aiding in water drainage.

  • New weeping tiles are installed to divert water from the foundation, surrounded by clean ¾” gravel to ensure proper drainage.

  • The dug-out soil is then replaced and compacted firmly to avoid any future ground movement.

  • After the work is finished, we thoroughly clean the site of any construction debris.

  • To wrap up, we repair and reinstate any outdoor spaces and landscaping that were affected by our work.
