Locating, mapping and drainage investigation across Gosford, Wyong and the Central Coast. No job too small. No project too large. From small contractors to major infrastructure.
The Central Coast sits between the Hawkesbury sandstone plateau and the coast, with Gosford, Erina and Terrigal on sandstone and sandy soils and the Tuggerah Lakes and Wyong flats on low-lying alluvium with a high water table. Radar reads well on the plateau and shorter in the wet lowlands; the lakeside suburbs carry shallow stormwater and sewer networks that flood and corrode, which is where much of the drainage investigation work comes from.
Electricity is Ausgrid, water and sewer are Central Coast Council rather than Sydney Water, gas is Jemena in the serviced areas and stormwater belongs to the council. The M1 Pacific Motorway, the Pacific Highway and the Main North rail line are Transport for NSW corridors, and the Gosford hospital and CBD renewal, the Warnervale and Wyong growth areas and the steady coastal rebuilds are the typical jobs. The Coast is about an hour from our Lindfield office up the M1.
The same accredited crew and AS 5488-2022 report across Central Coast and NSW, whether it's a single locate or a tier-one program.
Detection, tracing and marking of underground services using electromagnetic and ground-penetrating radar, to the accuracy each site demands.
Engineering-grade utility survey and drafting to AS 5488-2022, delivering 12D/DWG models, BIM-ready 3D strings and GDA2020 deliverables.
Safe vacuum potholing to positively identify services and achieve the highest Quality Level (QL-A), without damaging the asset.
GPR concrete imaging before cutting, coring or drilling. Locates rebar, post-tension cables, conduits and voids. Radiation-free, no site shutdown.
Push-rod and crawler camera inspection, connectivity mapping and condition reporting for pipes up to 2 m in diameter.
USTs, concrete substructures, voids and rock seams, plus unmarked-grave, forensic and archaeological investigations.
Central Coast Council, through its own water and sewer business. Its plans and standards differ from Sydney Water's and our surveys are delivered to its requirements.
On the sandstone around Gosford, Erina and the Peninsula, yes. In the low wet ground around the Tuggerah Lakes and Wyong the water table shortens the radar reach, so EM tracing and potholing carry more of the locate.
Yes. CCTV inspection, connectivity mapping and condition reporting of the lakeside stormwater networks is regular work for council and private clients.
The Central Coast is around an hour from our Lindfield office via the M1, and standard jobs are usually scheduled within a few business days, with 24/7 emergency call-outs.
