When you see sink holes forming on the outside of your foundation this is evidence of moving soil. Oftentimes, sink holes are pathways through the soil that allow dirt and mud to access interior waterproofing systems. This dirt/mud quickly compromises waterproofing systems with blocks and clogs leading to greater water penetration.
