Our Waterproofing Materials & Advanced Technology

At Waterproofing4Less, we use only the highest-quality materials and cutting-edge diagnostic tools:

01     Aquabloc 720-38

Superior waterproofing with low VOC content, outperforming traditional tar-based sealants.

02      Infrared Cameras & Moisture Meters

Detect hidden water damage not visible to the naked eye.

03     Drain Camera Equipment

Used to inspect underground pipelines for cracks or blockages.

04     We Follow All Bylaws & Permit Requirement

Many contractors skip utility locates, leaving homeowners liable for damages. We ensure Hydro, Gas, Bell, Rogers, and other underground utilities are properly located before excavation, saving you from fines up to $12,000.
