What is Leak Detection?

Escaping water travels along the pipe bedding and surfaces well away from the break, or drains into a storm line and never shows at grade at all — which is why a wet spot is a poor guide to where to dig. Leak detection traces the line first, then narrows the loss with ground microphones, correlators, hydrophones that couple into the water column at hydrants and valves, or tracer gas where the pipe material damps sound. The output is a marked point on the surface, so the excavation is sized to the repair rather than to the search.

What Markham Clients Get Out of It

• One excavation at the pinpoint instead of chasing a run of pipe
• Works where nothing shows at grade — most losses never surface
• Correlators and hydrophones recover signal that plastic pipe absorbs
• Tracer gas as a fallback that does not depend on pipe material at all
• Post-repair verification on the isolated section before it goes back in service

Leak Detection in Markham Conditions

Markham sits in a humid continental climate, with winter ground freeze reaching 48 inches — frost changes what ground penetrating radar returns, and it stops paint from bonding, so cold-season work leans on recorded offsets and coordinates. Local ground: Clay, Loam. Soil conductivity is the variable that decides how much of a locate radar can contribute, because conductive ground absorbs the radar pulse instead of reflecting it. Primary industries — construction, telecommunications, utilities — drive steady demand for leak detection across the York County area.

Ontario One Call (1-800-400-2255) requires advance notice — confirm the exact period with them before any excavation in Ontario. That notification is free and it is separate from leak detection: it brings out the member facility owners to mark the lines they own, and stops at the meter or the right-of-way. Wait for every member to respond before ground is opened.

When Markham Clients Use Leak Detection

• Municipal water main and distribution leak surveys
• Non-revenue water and minimum night flow investigations
• Private service line leaks between the meter and the building
• Slab leak pinpointing under residential and commercial floors
• Irrigation mainline and zone leaks on farms, parks, and courses
• Yard and building gas line leak checks past the meter
• Post-repair verification and pressure testing of isolated sections

What a Leak Detection Quote in Markham Depends On

Locating is quoted per job rather than off a rate card, because the work is a search and a search scales with the site rather than with the clock. On a Markham job, the things that move the number are how much ground has to be covered, how many targets are in play, whether there are meters, valves, risers, or panels a transmitter can be clipped to, what the lines are made of, what the local ground (clay, loam) does to the instruments, and whether you need surface marks or a record you keep.
