Hidden beneath this Ladson home's foundation, deteriorating PVC connections were causing mysterious water loss that puzzled the homeowner for months. The joints had separated due to ground shifting and age-related brittleness in the plastic. Our crew accessed the affected area and rebuilt the connections using proper solvent welding techniques and support brackets. These types of repairs require understanding how different materials respond to stress and environmental conditions. By addressing the root cause rather than just symptoms, we ensured the repair would last for decades. Complex pipe repair situations benefit from experienced troubleshooting and proven repair methods.
