Stone Foundation Waterproofing
Stone foundations are the most common for homes built before 1915. These foundations are a lot thicker than the block/poured foundations that are used today. Over time saturated soil causes damage to the mortar that holds the stone in place. Once moisture penetrates through the foundation it not only erodes the mortar but can also cause movement in the stones from the pressure of frost heaving in the cold weather. This can cause large holes to form in the foundation when the stones release from the wall. This will allow water to pool in the holes and slowly deteriorate the mortar holding the foundation stones together. In most cases some stones may need to be reset in their original places.
This method restores and waterproofs stone foundations.
This method requires the excavation of land in the affected area to the bottom of the foundation. Once the foundation is exposed it is then cleaned and reinforced with a new age hard mortar. Then the foundation is waterproofed to stop any moisture from causing damage. This will prevent any of the stones from shifting and causing major damage to the foundation in the future. In most cases any concrete above grade that sits close to the ground will deteriorate like around window frames, ledges and corners. This will require some parging to restore the top exposed part of the foundation and the overall look of your home.
Weeping Tile Drainage System
It is important that this type of foundation has a proper drainage system to help prevent water from sitting up against the foundation and causing damage. The weeping tile drainage system is installed on the exterior of the foundation below the footing and is connected to an interior sump pit. The water is collected into the sump pit and then removed by the sump pump.
