INNOVATION.

Utilised a concrete pour system to eliminate horizontal joints This had a positive impact Quality wise and the finish product reflects this.
The construction methodology implemented by Galldris eliminated the requirement of substantial size propping installation - and its installation risks – along with the risk of working at height while constructing these slabs.
Along the pit road channels, “U” bars were replaced by continuity systems of reinforcement “conty bars”.
Strong input from Galldris in regards to temporary works throughout the project. In particular, to the bogie drop pit where the suspended slabs were poured first before digging of the actual pit.
