Exterior Basement Waterproofing Markham
The exterior basement waterproofing method needs excavation and exposing of the foundation wall. We clean and inspect the outside of the wall for any cracks. Once excavated, we seal the walls with waterproofing membrane and weeping tiles or new drainage is positioned on the side of the footing. The final step is that we check the weeping tile connection to the drain or sump to ensure it is working perfectly.
Interior Basement Waterproofing Markham
The interior basement waterproofing process is for those who do not want to disfigure the outside appearance of their house. It ensures that landscaping is not harmed in any way. In this method drip moldings and wall vapor/barriers/retarders are installed to collect water seeping from wall cracks and other wall defects of the foundation. The water is directed to a drain which directs itself to a sump pump and finally the sump pump helps the water to flow out of the basement.
