Excavations are necessary for construction of firm foundations for the buildings. Deep excavations are very challenging as groundwater is prone to become an obstruction during the excavation progress.
When a leading contractor in Dubai was looking for a perfect dewatering sub-contractor for controlling ground water for the construction of a luxury hotel where an excavation of over 16 meters was required, Khansaheb Sykes was approached to control the water levels.
Deepwell dewatering is the most suitable method for controlling groundwater for excavations which are deeper and are not possible to be dewatered by installation of WellPoint’s. Our experts have installed gravity drainage system which is connected to the permanent deep well pumping station.
Considering the size of the plot, the dewatering is being carried out phase by phase. The first phase for excavation of lift pit area 1 has been successfully completed and connected to the permanent pumping system.
Once all drainage systems are dewatered, our engineers will withdraw the temporary installed deep well systems inside the plot area and the permanently deep well systems which are installed within the diaphragm wall will handle everything after that.
The installation of gravity drainage system is an added advantage as there will be no opening in the raft, the civil contractor doesn’t need to make any opening in the raft, making the drainage system full proof.
