Waterproof and Backfill with Drainage Aggregate

What happens here

Lay down a layer of tar paper or a similar waterproofing membrane against the exterior foundation wall, covering the repaired section. This membrane acts as a barrier against moisture. Carefully cut the membrane to fit around any obstacles, such as pipes or protrusions, ensuring full coverage. After installing the membrane, backfill the trench with free-draining aggregate, such as gravel. This gravel layer facilitates drainage, preventing water from pooling against the foundation. The backfill should be extended along both ends of the garage wall to ensure proper gravity drainage. The gravel is transferred by hand using a wheelbarrow.

Goal: Create a waterproof and free-draining exterior for the foundation.
