Client: Sirius Remediation
Contract: Breakout
Webfell Minerals were awarded the contract for the concrete breakout on the former Wellman Graham Works, Gloucester. Some 20,000m? of reinforced concrete slab and roadways, ranging from 150mm to 300mm in depth, were broken out at 300mm centres.
Sometimes known as rubblising, this enables the slab to be easily excavated, loaded into dumptrucks, taken to a primary crusher and then crushed to make a fill material, which then can be re-used on site.
The work was carried out with one Guillotine Breaker, with a 2.4m blade weighing 5.75 tonnes. This method is fast, clean and cost effective.
The concentration of breaking effort and energy ensures that debonding of concrete from reinforcement occurs, enabling both mesh and bar reinforcements to be removed relatively cleanly from broken concrete. This method of breakout is far quicker and more economical than any conventional methods.
