Slab Leak Detection and Repair in Dover
Slab leaks are common in homes built on concrete foundations, often caused by shifting soil or corroded pipes underneath. Our technicians use non-invasive methods like electronic leak detection and hydrostatic pressure testing to find these hidden leaks. Once located, we can perform targeted repairs, either by slab tunneling or direct access, minimizing disruption to your home. We work with many pipe materials, including copper, PEX, and PVC, providing a durable repair for your Dover property.
Advanced Leak Detection Technology in Dover, DE
The ability to accurately locate a foundation leak is essential for an effective repair. GNV Plumbing invests in advanced leak detection technology, including high-frequency listening devices and specialized camera inspections, to pinpoint leaks with precision. This technology allows us to identify the exact location of the break, whether it's a small pinhole or a major burst, cutting down on invasive searching and repair costs for our Dover, DE customers.
Drain Line Leak Under Foundation in Dover, DE
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 find cracks and separated joints. Repairs may involve tunneling, cutting the slab or pipe lining. We walk you through the trade-offs of each method.
Tunneling for Foundation Leaks in Dover, DE
In some cases, the best way to repair a foundation leak is by tunneling beneath the slab. This method lets our plumbers reach the damaged pipe directly without breaking through your home's interior flooring. GNV Plumbing is experienced in safe and efficient tunneling, limiting disruption to your Dover, DE home and ensuring a complete repair of the damaged pipe section.
Slab Leak Detection & Repair in Dover
Slab leaks are known for being difficult to detect, often showing quiet signs like warm spots on the floor or a sudden jump in your water bill. GNV Plumbing uses acoustic and infrared technology to accurately locate these hidden leaks under your concrete foundation. Once identified, we offer tailored repair solutions, whether it's a spot repair, re-routing, or pipe bursting, to restore your plumbing system in Dover without extensive damage to your property.
Post-Tension Slab Leak Repair in Dover
Many newer homes are built on post-tension slabs with steel cables under high tension. Cutting into these slabs takes 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.
PEX and PVC Foundation Leak Repair in Dover
Modern homes often feature PEX or PVC plumbing, which, while durable, can still develop foundation leaks due to ground movement or poor installation. GNV Plumbing has the tools and expertise to repair leaks in these plastic piping systems. We use proper fusion and solvent welding techniques to ensure strong, leak-proof connections, restoring the integrity of your plumbing system beneath your Dover foundation.
Direct Foundation Leak Repair in Dover, DE
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.
