GPR + EM dual technology. Every service has dedicated pages for all 47 BC cities (e.g. https://leak.ca/services/private-utility-locating/vancouver). - Key fact: BC One Call marks public utilities only to the property line; private-side services are the digging party's responsibility — the core gap private utility locating closes. ## Aerial inspection (10 services × 47 BC cities) - [Aerial Inspection Hub](https://leak.ca/services/aerial-inspection): Drone-based contact NDT — ultrasonic wall thickness (EN 12668-1/ISO 16831), high-temperature UT to 260 °C, EMAT (ASTM E1816-18), coating DFT, pulsed eddy current for corrosion under insulation — plus radiometric thermal programs (640×512, NETD ≤50 mK): roofs, solar farms, BESS, façades, industrial assets. No scaffolding, rope access, or shutdown. Transport Canada-certified RPAS pilots. City pages at https://leak.ca/services/aerial-inspection//. ## Drone leak investigation (10 services × 47 BC cities + 14 property types) - [Drone Leak Investigation Hub](https://leak.ca/services/drone-leak-investigation): Aerial leak detection across BC — radiometric thermal (640×512, ≤50 mK) + RTK photogrammetry, confirmed by ground acoustic crews. Services: underground water main leak surveys, reservoir & dam seepage detection, stormwater pond/outfall surveys, water tank & standpipe inspection, district energy loop surveys, irrigation leak mapping, podium/plaza deck investigation, post-storm portfolio triage, pipeline right-of-way screening, moisture orthomosaic mapping. City pages at https://leak.ca/services/drone-leak-investigation//; property-type pages at https://leak.ca/services/drone-leak-investigation/property/. - [For Commercial](https://leak.ca/services/drone-leak-investigation-for-commercial): Portfolio programs — roof baselines, deck investigation, storm triage, insurer-grade documentation. - [For Government](https://leak.ca/services/drone-leak-investigation-for-government): Municipal water infrastructure — NRW targeting, dams/dikes reconnaissance, GIS-ready deliverables, procurement-ready. - [Drone Leak Detection Guide](https://leak.ca/guides/drone-leak-detection): Complete pillar — radiometric physics, honest limits, costs ($750–$3,500 typical), fly-vs-walk decision rules. - [Drone vs Manual Roof Inspection](https://leak.ca/compare/drone-vs-manual-roof-leak-inspection): Drone survey vs walk-on IR vs roofer visual — coverage, evidence grade, and when each wins. - Key fact: distribution utilities commonly lose 10–30% of treated water to leakage; aerial thermal screening compresses kilometres of network into ranked suspect zones for acoustic ground confirmation. - Key fact: aerial leak detection is a screening layer — Leak.ca confirms findings with its own ground crews (acoustic correlation, probing, flood testing) before anyone digs or cuts. ## EM Scan & Line Locating + GPR (dual-method private utility locating) - [EM Line Locating Hub](https://leak.ca/services/em-line-locating): Electromagnetic line locating paired with Ground Penetrating Radar — the dual-method private locate. EM traces conductive lines (metal pipe, cable, tracer-wired plastic); GPR images the non-conductive plastic and clay EM can't see. 8 EM techniques each with 47 BC city pages: active line locating (direct connection/clamp), passive sweep (power/radio), inductive locating, sonde drain & duct tracing, tracer-wire locating & install, cable & sheath fault locating, depth estimation & mapping, and the combined EM + GPR utility clearance survey. - [EM + GPR for Pros](https://leak.ca/services/em-gpr-locating-for-pros): Private locating built for the trades — excavation contractors, plumbers, electricians, directional drilling, general contractors, landscapers, fencing & deck, foundation & piling, engineers & surveyors, utility & telecom crews. Each trade has its own playbook at https://leak.ca/services/em-gpr-locating-for-pros/. - [EM Line Locating Guide](https://leak.ca/guides/electromagnetic-line-locating): Complete pillar — active vs passive, the three signal-application modes, sonde, tracer wire, depth, and why EM is always paired with GPR. - [EM vs GPR Locating](https://leak.ca/compare/em-vs-gpr-locating): What each method finds and misses — and why a complete locate is both. - Key fact: EM finds only CONDUCTIVE lines (metal, tracer wire); bare plastic and clay are invisible to EM and require GPR or sonde tracing — which is why a defensible locate is dual-method. - Key fact: BC One Call marks public lines to the property line only; private services beyond it (the lines most digs strike) require a private EM + GPR locate. - Key fact: active locating applies a signal by direct connection, signal clamp (for live cables), or induction (where no access point exists); passive locating detects existing power/radio signals. ## Advanced & specialty detection methods - [Tracer Gas Leak Detection](https://leak.ca/services/tracer-gas-leak-detection): Safe hydrogen forming-gas (5% H₂ / 95% N₂) introduced into the isolated line escapes at the leak and is detected at the surface — pinpoints pressurised, plastic, low-flow, under-slab, and mechanical-piping leaks that acoustic methods can't hear. Pairs with helium for ultra-sensitive work. - [District Energy & Thermal Loop Leak Detection](https://leak.ca/services/district-energy-leak-detection): Buried hot-water, glycol, and chilled-water distribution mains for campuses, hospitals, civic precincts, and energy utilities — aerial thermal screening + ground confirmation.

What it means (many BC utilities run AMI smart metering that flags 24-hour continuous flow), the free 5-minute meter test, the inside/outside split test, precise leak pinpointing, and documentation for leak adjustment applications. City pages at https://leak.ca/services/city-water-leak-notice/; sector playbooks for residential, commercial, and governmental properties. - [City Water Leak Notice Guide](https://leak.ca/guides/city-water-leak-notice): Complete pillar — responsibility split at the meter, common culprits in probability order, adjustment program mechanics, 12 FAQs. - Key fact: in most BC municipalities the utility owns up to the meter; the property owner owns everything past it, including the buried service line — which is why the city notifies the owner. - Key fact: many BC utilities offer a leak adjustment (partial bill forgiveness) for promptly repaired, documented leaks — policies vary by municipality; a dated detection report plus repair invoice is the standard evidence package. - Key fact: the most common notice culprits, in order: buried service line leaks, running indoor fixtures, irrigation failures, slab leaks, pool auto-fill systems. ## Municipal water main leak detection (8 services × 47 cities + 16 region programs) - [Municipal Water Main Hub](https://leak.ca/services/municipal-water-main-leak-detection): Network-scale leak detection for BC water utilities — acoustic water main surveys (±0.5 m correlation pinpointing), leak noise logger programs (2–4 a.m. listening windows), district metered area (DMA) / minimum night flow analysis, step testing & zone isolation, trunk & transmission main methods (low-frequency, sparse access), hydrant & valve appurtenance surveys, active water main break location, and full non-revenue water (NRW) programs. City pages at https://leak.ca/services/municipal-water-main-leak-detection//; region pages at https://leak.ca/services/municipal-water-main-leak-detection/region/ (16 BC regions). - [Municipal Guide](https://leak.ca/guides/municipal-water-main-leak-detection): Complete pillar — correlation physics, PVC/AC challenges, night flow analysis, real vs apparent losses, program sequencing, costs. - [Noise Loggers vs Acoustic Survey](https://leak.ca/compare/noise-loggers-vs-acoustic-survey): Permanent loggers vs lift-and-shift campaigns vs crew surveys — loggers RANK, crews PINPOINT. - Key fact: water utilities commonly lose 10–30% of treated water to leakage; a single 1 L/s leak wastes over 31 million litres per year. - Key fact: water main breaks rarely sit under where water surfaces — escaping water travels along pipe bedding, sometimes tens of metres; acoustic correlation before excavation is how crews dig once. - Key fact: real losses (leakage) and apparent losses (meter under-registration, billing gaps) require entirely different fixes — an AWWA M36-style water balance splits them before budget is spent. ## Concrete scanning (12 services, 6 with 47-city coverage) - [Concrete Scanning Hub](https://leak.ca/services/concrete-scanning): Pre-coring clearance, post-tension cable mapping, rebar & conduit locating, void/thickness verification, parkade deck condition — 1.6 GHz GPR, one-sided access, no radiation, same-visit drilling clearance. - [GPR vs X-Ray comparison](https://leak.ca/compare/concrete-scanning-vs-xray): The 95/5 rule — when radar wins (almost always) and when radiography is genuinely warranted. - [Concrete Scanning Guide](https://leak.ca/guides/concrete-scanning): Complete pillar — accuracy (±5 cm), depth (≤45 cm at 1.6 GHz), PT-vs-rebar identification, costs ($350–$1,500), 12 FAQs. - [For Contractors](https://leak.ca/services/concrete-scanning-for-contractors): Same-visit scan-and-drill workflow, per-location documentation, account terms. - [GPR vs Chain Drag](https://leak.ca/compare/gpr-vs-chain-drag-parkade): Parkade deck assessment — existing delamination vs predictive corrosion mapping. - [Concrete Scanning Cost in BC](https://leak.ca/guides/concrete-scanning-cost): Pricing guide — $300–$1,500 typical single visit, day rates, drivers, ROI vs a $20K+ strike. - [Concrete Scanning Depth & Accuracy](https://leak.ca/guides/concrete-scanning-depth-accuracy): Technical guide — ~30–45 cm depth at 1.6 GHz, ±cm lateral, depth estimate ±10–15%, what GPR can/can't see. - [GPR vs Cover Meter (Rebar)](https://leak.ca/compare/gpr-vs-cover-meter-rebar): A pachometer measures shallow cover; only GPR sees conduit & post-tension to clear a core. - [GPR vs Impact Echo (Slabs)](https://leak.ca/compare/gpr-vs-impact-echo-slab): Imaging vs sounding — GPR maps & clears, impact echo grades delamination; often used together. - [Scanning for Anchors & Dowels](https://leak.ca/services/concrete-scanning-for-anchors-dowels): Clear rebar/PT/conduit before every fastener and post-installed rebar hole. - [Scanning for Solar & Rooftop Equipment](https://leak.ca/services/concrete-scanning-for-solar-rooftop): Clear the full anchor grid on post-tensioned roof/podium/parkade decks before racking goes down. - [Post-Tension Scanning Before Coring](https://leak.ca/guides/post-tension-scanning): Safety guide — tendons carry 15–20 t;
