What is Slab Leak Detection?
Slab water leak detection uses advanced leak locating equipment to detect and diagnose hidden leaks below the foundation of your home or commercial building. Undetected slab leaks can cause more than simple water damage. A leak can progress from simple water flow to foundation erosion quickly. Prevent structural damage due to slab instability by finding and fixing slab leaks quickly, with the use of advanced leak detection technology.
Uses of Slab Leak Detection
- Leaks that connect your building pipes to city water supplies
- Leaks on sewer lines and septic tanks
- Leaks from hose and landscaping hook-ups
- Line locations of utilities like electric and gas
- Leaks inspections for insurance and home purchase
- Hidden Leaks under concrete slabs and driveways
How Does Slab Leak Detection Work?
Slab leak detection is used to check ground lines with ultrasonic technology in conjunction with infrared detecting equipment. Tracer gas is injected into piping areas identified as a potential risk and then analyzed by a computer. This analyisis is done not once but up to three times to verify exactly what is happening within the pipelines. Often this process will detected additional leaks than those initially suspected, allowing you to fix problem early and minimize potential property damage.
Slab leaks are a risk in any foundation, especially with the frequent rainfall from the Pacific Northwest adding to any pre-existing moisture issues. Since these leaks often cannot be detected until extensive damage is already done, it’s important to call in professionals as soon as a leak is suspected to proceed with immediate repair.
