Waterproofing your founda on should be a high priority for every homeowner. If you are considering waterproofing your home, it is important to inves gate and determine what system will be most effec ve. In this guide, we will help you determine the most important differences between exterior and interior waterproofing systems, so you can make an informed decision regarding your home s basement and founda on water concerns. How Our Exterior Water Proofing System Works: Founda on waterproofing is a significant investment; therefore, it is important to choose the system that will protect and add value to your home. Nevertheless, there are as many systems and methods as there are companies who install them. Our innova ve exterior water proofing system is guaranteed to redirect water away from your home s founda on and crawlspace.

Step 4: U lizing our patented and effec ve method, we install a drainaige system that directs water away from your home. Step 5: We backfill the trench with gravel. According to North Carolina Building Code, gravel and granular material are the best and only method for backfill that prevents water issues. *See diagram on last page Excerpt from North Carolina Building Code regarding founda on and Backfill: The provisions of Table are only applicable where the following condi ons are met: 1. The founda on wall does not exceed 8 feet (2438 mm) in height between lateral supports, 2. The terrain surrounding founda- on walls is graded to drain surface water away from founda on walls, 3. Backfill is drained to remove ground water away from founda on walls, 4. Lateral support is provided at the top of founda on walls prior to backfilling, 5. The length of founda on walls between perpendicular masonry walls or pilasters is a maximum of three mes the basement wall height, 6. The backfill is granular and soil condi ons in the area are nonexpansive, and 7. Masonry is laid in running bond using Type M or S mortar.

Direc ng groundwater and rain runoff away from your home, is the only way to effec vely prevent basement and founda on water issues. How Interior Water Proofing Systems Work: Interior waterproofing systems address water issues from within your basement. Generally, they u lize French drains to move the water to a sump pump, where it is then exited from your home s basement or founda on. Contractors install drainage pipes under your home and near trouble spots in your founda on walls. Though interior systems are typically less expensive than tradi onal exterior systems*, there are several important factors to consider: Interior systems allow water to penetrate your home s founda on. The sump pump must remain opera onal at all mes. If a pipe or drain fails, you may not realize it un l there is significant water damage. Interior systems do not address humidity issues. Any moisture remaining can lead to the development of mold Interior systems allow the water to pass through your founda on walls and into the block cores. These systems use weep holes that are drilled near the base of the wall to drain the water into a plas c gu er system that sits on top of the foo ng inside the founda on wall. The weep holes cannot drain 100% of the water, because the mortar droppings inside the block cores are not pitched toward the holes. As a result, moisture collects inside the weep holes and remains inside the block wall un l it becomes stagnant, growing mold, and corroding the base of the founda on wall. *Park s System is comparable in cost and o en less expensive than interior systems.
