Featured Project

Exterior Waterproofing of Basement in North York

In North York, Alterra Landscaping successfully undertook the waterproofing of a leaky basement with a comprehensive approach. The project involved excavating the area to a depth of 6 feet. To establish an effective waterproofing system, we installed the Hydro Guard rubberized membrane, an air-gap drainage membrane, and a drainage tile. This strategic combination ensures robust protection against water infiltration, creating a durable barrier to safeguard the basement from leaks and potential water damage.

Homestars Review
Old driveway of 1200 sq ft was removed. Driveway was excavated to a depth of 18". New base material was installed and properly compacted. New interlock pavers were expertly installed (flat side to side, top to bottom). Project completed within 5 days and on budget. Very professionally done

Frequently asked questions

What is the difference between dampproofing and waterproofing for basements?
Dampproofing is a basic moisture control measure, whereas waterproofing involves a comprehensive system to prevent water penetration. Dampproofing is less robust and doesn't provide the same level of protection as waterproofing.
How is a water test conducted for assessing basement leaks from the outside?
We conduct a water test by turning on a hose and placing it against the area of the home's foundation. This helps determine if there is a foundation leak causing water to enter from the outside.
What are the steps involved in exterior basement waterproofing?
The process includes locating the breach in the foundation, excavating and exposing the footings, removing and replacing old weeping tile, cleaning and inspecting foundation walls, applying rubber and polyethylene membranes, installing gravel over weeping tile, and backfilling and compacting the area. This comprehensive approach ensures effective waterproofing and prevents further water penetration into the basement.
