Rock Breaking Contractor in Christchurch

Rock breaking is an important task in fields like municipal engineering, mining, quarrying, and road excavation. Rock breaking may sound like a rugged and rustic job, but in reality it’s a highly technical process and requires both professional and scientific expertise.

Conducting blasts to break rock is an age-old procedure that’s almost obsolete at this point. This is because the process creates vibrations in the surrounding areas, often resulting in dangerous fly rocks and fly stones, while also producing toxic gases.

Though blasting is practised in situations where other methods won’t work, innovation in the field of rock breaking has led to the introduction of many other much safer methods that get the job done without damaging side-effects.

These new and improved methods for rock breaking reduce vibrations and eliminate fly stones and toxic gases from the process, while also ensuring cracks don’t develop post-blast. To employ the latest rock breaking methods on your project, hire Steve Mallinson Contracting for rock breaking in Christchurch and the surrounding areas.

Foundation Waterproofing Services in Christchurch

When it comes to professional construction work, some projects require waterproofing before the concrete foundation is laid. This process is common in urban locations where the water table is high, especially with buildings that are prone to foundational water seepage due to their proximity to marshy soil, or the presence of a river nearby etc.

In the past, the only solution to this problem was to use sheet membranes, however experience shows they were not able to effectively keep the seepage at bay over the long-term. Nowadays, waterproof concrete offers a superior solution. An expert in foundation waterproofing can provide you with a convenient solution for waterproofing the base of any building. Trust Steve Mallinson Contracting for any and all needs related to foundation waterproofing in Christchurch and the surrounding areas.
