Drain Line Leak Under Foundation in Mount Pleasant, SC
Leaks in drain lines under the foundation can be harder to detect because they are not under constant pressure. We use camera inspection and hydrostatic testing to locate cracks and separated joints. Repairs may involve tunneling, cutting the slab or pipe lining. We explain the trade-offs of each method.
Direct Foundation Leak Repair in Mount Pleasant, SC
When the leak is in an accessible spot and the rest of the pipe is in good condition, direct repair is often the most economical choice. We cut a small opening in the floor, excavate to the pipe and replace the damaged section. The soil is compacted and the concrete is patched to match. Flooring can then be restored by your flooring contractor.

Advanced Leak Detection Technology in Mount Pleasant, SC
The ability to accurately locate a foundation leak is essential for an effective repair.

Copper Pipe Leak Repair in Mount Pleasant, SC
Many older homes in Mount Pleasant, SC have copper water lines beneath their foundations, which can corrode over time due to soil conditions or water chemistry. Most municipal water in South Carolina comes from rivers and reservoirs, so it tends to run soft and leaves less scale than in many other states. When these copper pipes develop pinhole leaks or cracks, they require specialized repair. Our technicians fix or replace sections of damaged copper piping, ensuring a durable seal that holds up to pressure and ground movement and helps prevent future leaks.

Foundation Leak Detection in Mount Pleasant
Accurate detection is the most important step in foundation leak repair. We isolate hot and cold lines and pressure test them to confirm a leak exists. Then we use acoustic listening equipment and electronic line tracing to find the exact spot beneath the foundation. Thermal imaging helps confirm hot water leaks by showing warm spots on the floor.
