During heavy rains or snowmelt water accumulates around the foundations of houses. Water pressure on the foundations causes water infiltration or absorption of water by the concrete. The evacuation of this water is essential, otherwise the concrete will inevitably deteriorate due to excess humidity and water infiltration in the basement.
In recent years, during the winter, it rains during the day and at night the water freezes. This phenomenon forms ice dams around the house as well as along the intersections with the joints of the brick walls and patio doors. In addition, the floor is covered with a layer of ice and in both cases, the water cannot drain away. Unable to evacuate, it infiltrates through the first joint or crack it encounters.
If you notice the following symptoms
○ Water infiltration or wet concrete
○ Persistent excessive humidity (above 55% in summer)
○ Efflorescence (traces of white powder)
○ Bad smells or humidity insects
○ Mushrooms and/or mold at the bottom of the walls
○ Black streaks on wood and paper on the back of the gypsum board
○ Degradation of foundation walls (chipping, crumbling)
One or more deficiencies are most likely the cause.
○ Water infiltration through cracks
○ Dry joint, construction joint, wood in concrete, etc.
○ Lack of perimeter drain for footing drainage (often ignored before the ’70s)
○ Existing drain ineffective or non-compliant
○ Reverse drainage slopes
○ Make all corrections of anomalies (cracks, holes, joints)
○ Epoxy and polyurethane injection
○ Installation of waterproofing membrane
○ Drainage trench
○ Window well
○ Mold treatment
○ Trench drain
○ Drain box
○ Sump pump
○ Check valve
○ Heating cable
