Exterior Systems require that the basement walls are excavated all the way down to the footer. If found damaged, we can repair, re-align or replace the drain-tile. If the basement wall has bowed due to age or ground pressure, demolition and rebuilding are completed without delay. New Tuf-N-Dri waterproofing is installed with a drainage panel and the excavation replaced. We offer a transferable lifetime warranty on our repairs and the intergrity of the waterproofing system.
