Wet/saturated soil creates Hydrostatic pressure that pushes water through cracks or holes in your basement walls or floor.
Exterior Waterproofing is the application of a sprayed, troweled, applying rubberized membrane or an asphalt coating to the foundation wall.
A perforated drainage system installed beside the foundation footing collects water from around the footing which channels the water to the main drainage or sump pump system.
A dimpled waterproofing membrane is then fastened to the foundation wall which protects the wall against moisture or common soil conditions and also gives moisture a path down to the weeping tile.
One foot of three quarter inch gravel is then placed over the weeping tile which will filter water into the drainage system.
