Basement Exterior Waterproofing
Basement exterior waterproofing involves excavating down to the footer of the home in the affected area of the home. Once we have exposed the work area, we clean the foundation wall and footer to prepare the damaged area for an asphalt material called Blackjack or like type product. This is generously rolled on or brushed on to seal the pores in the block. Next, we apply a second asphalt based material called Bituthene or like type material. This material comes in rolls and adheres to the Blackjack material on the foundation wall. Then we install a protective flex board called Hydroduct over the Bituthene in order to protect it from gravel and dirt. Finally, we back fill the trench using gravel and dirt and create a positive slope away from the house to promote proper drainage.
