Smart move checking before you dig! Striking a main water line or hitting hidden cables with a post-hole digger is a total nightmare. When we built our timber deck over in Kensington, we used https://leaksrus.com.au/service-areas/ for a full ground scan. Besides their standard leak detection work, they actually specialize in underground pipe and cable locating using non-invasive scanning technology. They service all across Sunshine, Braybrook, Flemington, and the surrounding suburbs. The tech mapped out our whole underground utility layout, marked the exact line paths on the ground, and even found a tiny weeping joint near our outdoor tap that we didn't know about. Super accurate work and saved us from a massive potential repair bill!
