LDJ Heavy Diesel Service was founded to keep the mining and construction industries moving with top-tier maintenance and repair solutions. With 25+ years of combined experience in our leadership team, we specialise in exploration drill rigs, blast hole overburden drills, and top hammer drills, ensuring maximum uptime and performance for our clients.
