About his

Screw piles are mini piling contractors in north west generally created from architectural steel. The tremie technique of placing concrete involves reducing a pipeline to the base of the excavation, the pipe end at the top of the excavation is connected to a concrete receptacle. The hoper and also the pipeline are then billed with the damp concrete mix. The pipe is after that slowly lifted out of the excavated hole, putting concrete as it goes. Throughout the training process, concrete is continuously renewed to the receptacle in order to keep the system completely charged.
