Water Line Reroute in Grand Forks
Rerouting abandons the leaking line under the foundation and runs a new line through the attic or walls. This avoids breaking concrete and removes the risk of future leaks under the slab. We typically use PEX for reroutes because it is flexible and resists corrosion. Drywall openings are kept small and neat for easy patching.

Post-Tension Slab Leak Repair in Grand Forks
Many newer homes are built on post-tension slabs with steel cables under high tension. Cutting into these slabs requires care and scanning to avoid hitting a cable. We use ground-penetrating radar or other scanning methods before opening the floor. When risk is too high, rerouting the plumbing is usually the safer option.
Basement Wall Sealing and Waterproofing in Grand Forks, ND
For homes with basements in Grand Forks, ND, wall leaks can be a significant concern. We offer comprehensive basement waterproofing services, including interior and exterior sealing. This may involve applying waterproof coatings, sealing cracks with polyurethane or epoxy, or setting up interior drainage systems. These measures stop water from penetrating porous concrete and masonry, keeping your basement dry and healthy.
Direct Foundation Leak Repair in Grand Forks, ND
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, dig down 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.
Copper Pipe Leak Repair in Grand Forks, ND
Many older homes in Grand Forks, ND have copper water lines beneath their foundations, which can corrode over time due to soil conditions or water chemistry. Many rural homes get water from private wells or rural water systems, and iron and sulfur odors are common complaints. When these copper pipes develop pinhole leaks or cracks, they require specialized repair. Our technicians repair or replace sections of damaged copper piping, ensuring a durable seal that withstands pressure and ground movement and helps prevent future leaks.

For extensive foundation leak repairs, especially those involving structural changes, re-piping, or significant excavation, a permit may be required by local building codes. HPN Plumbing will help determine if a permit is needed for your specific repair and assist with the application process to stay in compliance.
