Excavating down to the footer of the home in the affected area is the first step in Exterior Waterproofing in Knoxville homes. 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. 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. Bituthene 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.
