Subterranean Service Locations WA (SSLWA) was established in August 2015 in Geraldton WA.  Peter Henderson & Derek McShane (Managing Directors) created SSLWA to facilitate the growing Civil Construction industry throughout the Mid-West & North West.  They sought to fill a niche in the local market as there was no solely dedicated underground service locating company based in the Mid-West.  Their need to protect existing underground services from damage was a key component in the company’s establishment.


From this they expanded, with the help of their clientele base, into new service installations, damage investigation & baseworks.  SSLWA offer their services throughout the entire state of Western Australia.


SSLWA is an equal opportunity company that values its employee’s contributions to its success & expansion
