In a low fold the wall on the uphill side holds back everything the slope above sheds.
A house sitting in one of the low folds around Sunny Side is at the bottom of a drainage path, and any buried wall on the uphill side is holding back soil that the whole slope above keeps recharging.
Piedmont clay keeps that water in place once it arrives, so the wall carries the load for weeks at a stretch. That is what produces the horizontal cracking and the inward curve we get called about.
The most effective single step here is uphill. A cutoff drain across the high side removes the volume before it reaches the wall, and on this terrain it discharges by gravity. Perimeter drainage handles the remainder, and bracing sized from the measured deflection holds the wall.
The scope is fixed before we start on a Sunny Side home, so nothing gets added once the crew is underneath.

Trench Guys came to my home and corrected a sagging kitchen floor. They did a great job and guarantee their work for 10 years! I absolutely will be calling them anytime I need help.
I don't usually write reviews but John and his crew are absolutely awesome. They did my crawl space encapsulation. I got other quotes - don't waste your time with the other guys. Outstanding service at an incredible price!
Thank you Trench Guys for repairing our foundation. John gave our home a thorough inspection and explained the process so we knew exactly what the problem was and our options. They worked hard and were friendly and knowledgeable.
