Dubai: Property developer Nakheel says it has completed more than half of the ground improvement works at The Palm Jebel Ali.
The company is currently using a technique known as vibrocompaction, where specially designed vibrating probes increase the bearing capacity of the soil, making it ready for construction.
The work aims to ensure that no land subsidence can take place in the future.
Currently 18 vibroprobes are being used at the site, each weighing approximately 2,600 kilograms and capable of up to 1,800 revolutions per minute, resulting in a force of 30 to 50 tonnes, Nakheel said.
"The process ensures that the reclaimed land mass of The Palm Jebel Ali is strong enough to build buildings of significant height," said Marwan Al Qamzi, managing director, The Palm Jebel Ali.
Describing the process, Al Qamzi said the long, hollow probes go through the entire depth of reclamation until they penetrate the seabed's hard layers at average depths of 15 metres.
During this process, the combined action of vibration and the jetting of water rearrange loose sand grains into a compact state.
Sand is then added from the ground surface to fill the space created by the vibrator and to ensure that any soft layers on the sea bed are densified.
