Exterior Basement Waterproofing
Does your basement leak during heavy rain?
One of the best waterproofing solutions to prevent seepage of water into your home, and fix basement leaks, is exterior/external waterproofing.
How it’s done
This repair is done from the outside of your home by excavating the ground surrounding the foundation, replacing weeping tiles (if necessary), and utilizing moisture-proof rubberized materials and drains to redirect water away from foundation walls and prevent further seepage.
How are cracks waterproofed?
Hydrostatic pressure
Hydrostatic pressure is the build-up and pressure of groundwater on your foundation, that causes water seepage through cracks in your basement floor or walls. Prime Waterproofing’s method prevents water from penetrating the foundation by reducing the hydrostatic pressure build-up.
Basement window wells
If you have near-grade basement windows, then water may be building up around your basement window wells, which can cause leakage through the windowsill.
Brick or block foundation walls
Brick or block foundation walls contain mortar joints and air pockets that allow water pooling and then inevitable water flow through the crevices of your walls.
Deterioration of the waterproof sealer located on the ‘sill’
Deterioration of the waterproof sealer located on the ‘sill’ – which is where the top of your foundation meets the bottom of your bricks.
Benefits of Exterior Waterproofing
- It eliminates moisture problems, maintains air quality, and keeps your basement dry and free from possible mould. Since the water is dealt with from the outside, it never comes into the home.
- It prevents mould, musty smells, and possible allergic reactions.
- Increases structural strength, preventing cracks from hydrostatic pressure and shifting floors.
- Peace of mind that your home, furniture, and finishes are protected during heavy rainfalls, floods or melting snow.
- It provides a liveable space that isn’t damp.
- Increases your property value, as water and moisture issues may decrease the value of your home.
