There seems to be some confusion about the role of grading for a basement that is prone to leaks. In our experience, if you already have water entering your basement, then: raising the grade alone will do little to stop it from happening again.
Did you know that water can move underground and still create hydrostatic pressure against an unprotected foundation? This often happens when the ground becomes saturated, such as during early spring or after heavy precipitation. Climate change is also causing more frequent heavy rainfall events in the Kingston area.
Adding more fill against your foundation can increase lateral pressure on exterior walls. When combined with poor drainage and over-compacted soil, foundation walls can become overloaded and begin to fail by bowing inward or cracking due to excessive pressure.
In Kingston, this risk is even higher because of the heavy, expansive clay soil that absorbs water and becomes extremely heavy when saturated. The added weight can exceed what your foundation was designed to handle.
Loyalist Waterproofing Services stop basement leaks properly by carefully excavating affected areas and making permanent repairs to foundation walls. Installing an air-gap membrane ensures proper separation and drainage of wet soil, protecting your foundation long-term.
Our multi-stage approach guarantees that water can no longer enter your basement again.
