HydroTrace supports construction & civil across Gauteng with technical diagnostics, underground infrastructure investigation, trenchless pipe rehabilitation support and utility mapping services.
Undetected underground leaks can result in structural deterioration, escalating municipal costs, operational disruption and long-term infrastructure instability.
Recurring blockages, root intrusion, collapsed drains and displaced joints require CCTV inspection before excavation or replacement decisions are made.
Utility locating and GPR scanning help reduce excavation risk before drilling, trenching, coring or civil construction begins.
Infrastructure failures in operational facilities can interrupt tenants, staff, customers and critical site operations.
Typical diagnostic situations encountered on construction & civil projects across Gauteng. Each situation is handled diagnostic-first to minimise excavation and avoid repair scope errors.
Before trenching, piling, drilling, coring or boring on any site, buried services must be located and marked. Electromagnetic location plus GPR scanning identifies water, sewer, stormwater, telecoms, fibre and electrical services within survey reach.
Brownfield projects and renovations frequently uncover drainage that doesn't match the as-built drawings. CCTV inspection and dye/smoke tracing verify the actual layout and condition before designing connections or modifications.
Post-installation CCTV inspection of new gravity sewers and stormwater lines documents installation quality and identifies any defects requiring rectification before handover or sign-off.
Same-day or next-day utility location is usually achievable within Gauteng. Larger scope work, including full-site GPR surveys, is scheduled to suit the construction programme.
Electromagnetic location accuracy depends on the type of service and ground conditions. Typical depth indication accuracy is within around 10–15% on accessible metallic and traceable services; GPR adds non-metallic detection capability within reach of the antenna.
Yes. Located services are marked on site (paint or pegs as appropriate) and a written report with photographs is provided for the construction file.
