Manchester Commercial Slab & Under-Floor Leak Detection
Locating pressurized lines leaking under commercial slabs, basements and lower levels, so the floor is opened at one spot with the rest of the building in use.

Property managers, boards and owners in Manchester call us for commercial slab leak detection when a persistently wet hallway, utility room or lower, or when a slab line that has failed before. On multi-family along Mile Hill Drive the lines are long, the drawings are missing, and fill and beach deposits on Colchester Drive hides the water. We're down Mile Hill Drive from Port Orchard, with the gear on the truck.
The job on Manchester properties
The order matters: listen through the slab, then open one spot, then patch and reopen. On the fuel depot's adjacent properties near Mile Hill Drive the second step is the long one, because hardpan up Mile Hill and the length of the private system set the pace. The result is one opening in the slab, not and written report with photos.
A water bill that climbs with no exterior is the other common trigger on the fuel depot's adjacent properties. We listen through the slab, which on a Manchester site through hardpan up Mile Hill usually takes an overnight visit, then open one spot and patch and reopen. The owner ends up with written report with photos they didn't have before.
What's under Manchester's larger sites
What we know about Manchester's larger properties: manchester's commercial and community properties sit on the Rich Passage bluff and in the village near the state park, on Manchester Water District meters, with lines that run downhill toward the beach. On waterfront community properties on Rich Passage near the village we plan for till bluff above Rich Passage and for a system with no drawing.
We trace the line down the slope and pinpoint acoustically, then dig at the break rather than at the bulkhead where the water showed up.
Multi-family along Mile Hill Drive and small commercial in the village in Manchester share the same vulnerability: a private system in till bluff above Rich Passage with no drawing and a master meter that only reports totals. Commercial slab leak detection turns that into floor patched and area reopened and a located problem near Colchester Drive.
One crew, start to finish
On small commercial in the village near Manchester State Park we've done commercial slab leak detection after hours with the site taped and lit, pumps running, and residents told what to expect. Down Mile Hill Drive from Port Orchard, and the report with photos goes to the board or owner the next morning, along with a candid note about the rest of the system under clay seams and seeps on Beach Drive.
