Service 01
Lead serviceDrilling and blasting is our main trade. We plan, drill, charge and fire controlled blasts for rock excavation on road, foundation, trench and site development work.
Much of our work is close to houses, open roads and power lines. Every blast follows a written design and is fired by a licensed shot-firer, with explosives supplied from our own licensed stock.
Applications
Our method
Our engineer inspects the rock, nearby structures, utilities, access and drainage, and records what must be protected.
A written blast design is prepared for the site and checked against the protection needs found in the survey.
The design is signed off, required permits are confirmed and the police and neighbours are informed before work starts.
Holes are drilled, measured and logged against the design. Any change is recorded before charging.
Explosives are issued from licensed stock, recorded and loaded by licensed staff only. Mats are placed where required.
The exclusion zone is cleared, sentries are posted, warnings are sounded and the licensed shot-firer fires from a safe position.
The area is checked for misfires before the all-clear. Results and monitoring readings are recorded and shared with the client.
