Groundforce's MegaBrace system has been used to support two large excavations for a new recycling plant in Chirk, Wrexham.

The shoring supplier, working for main contractor DJ Construction, designed a propped cantilever solution to support the 24m by 12m by 3. 6m deep and 15m by 13. 8m by 6m deep sheet piled excavations.

The modular design meant components could be easily handled, allowing the system to be installed within a day.

The props were positioned above ground to ease excavation, with minimal cross strutting to maximise the clear workspace. The smaller excavation was strengthened with four braces across each corner, while the longer pit was given extra lateral support by a single 10m long hydraulic strut at the midway point.

Chipboard manufacturer Kronospan is developing the site into a hi-tech facility to recycle logs and timber residue into chips for manufacturing.

The processing machine is over 80m long and must be mounted on strong foundations capable of withstanding heavy vibrations.

Work began on the £700,000 contract in May and it is scheduled to finish in August.
