Toronto is a dynamic, diverse metropolis where modern high-rises and historic homes coexist. However, the city's heavy seasonal rains, rapid snowmelt, and aging infrastructure present unique challenges for homeowners—leading to basement flooding, water intrusion, and drainage issues. At Waterproofing4Less, we specialize in comprehensive basement waterproofing and drainage solutions designed specifically for Toronto properties. With over 25 years of local expertise, award-winning service, and more than 750 positive reviews, our high-performance systems protect your foundation, preserve indoor air quality, and deliver lasting peace of mind in the Greater Toronto Area.
At Waterproofing4Less, we use premium materials and cutting-edge technology to deliver optimal performance
We use this premium water-based, low VOC waterproofing product, which outperforms traditional tar-based sealants by forming a durable, flexible barrier that effectively prevents water intrusion
Our toolkit includes infrared cameras to detect hidden wet areas, moisture meters to measure unseen moisture levels, and drain cameras to inspect pipelines and sewers for blockages or damage.
We rigorously adhere to all bylaws by calling utility locates (for hydro, gas, Bell, Rogers, etc.) before excavation. This critical step prevents accidental utility damage and protects you from fines up to $12,000.
Our professional team uses these tools to ensure that we only perform work that is truly needed—never recommending unnecessary repairs for profit.
We provide a dual approach that addresses both interior and exterior waterproofing, along with specialized services such as sump pump installation, backwater valve installation, and drain repair & replacement.
Protect work areas with tarps and remove wall coverings to expose concrete, cinder block, or brick surfaces for accurate assessment.
Excavate a precise trench along the wall following detailed diagrams and properly dispose of all debris.
Install the Delta MS drainage membrane (drilling through blocks if necessary) and integrate Big O weeping tile with a filter into the drainage system.
Encase the weeping tile in gravel, backfill and re-cement the floor, then remove all tarps and thoroughly clean the area.
Safeguard the surrounding landscape with tarps and excavate down to the footing level to expose the foundation.
Clean the wall, grind out cracks into a V-shape, repair with hydraulic cement, and apply a parging mix for optimal surface readiness.
Apply a high-quality layer of Aquabloc 720-38 to form a superior waterproof barrier, then reinforce with fiber mesh and an additional 4mm poly layer for extra protection.
Install a new Big O weeper with filter, encase it with ¾” clear gravel, perform required utility locates, and backfill and compact the soil for a finished, compliant installation
