Piled Foundations
A pile is a type of foundation commonly used in property construction. Piles are used as a substitute for other foundation methods when earth around the property isn’t strong enough to support conventional foundations. Piles are used to stack up more layers of soil and keep them walled in, providing a firmer base.
In the past piles have been made from wood and other naturally occurring materials. Modern piles are made using reinforced concrete and pre tensioned concrete.
Excavation Retention System
To facilitate the construction below the ground level, suitable type of excavation systems are employed.
The selection of the system is dependent on a number of factors mainly
Depth of excavation
Water table level
Soil condition
Nature of structure to be built below the ground level
Al Nuaimi Foundations & Concrete has the capabilities to install excavation retention systems to facilitate excavation up to 40 meter below the ground level by deploying any of the following types of systems:--.
Diaphragm walls.
Secant pile walls
Contiguous pile walls
Sheet pile Wall
Soldier Pile Wall
Tie back grout anchors are to be used to achieve greater depth of excavation in conjunction with any of the above mentioned systems
Dewatering The object of groundwater dewatering and control is to prevent an excavation below the natural water table and to achieve a groundwater control policy at the construction sites using dewatering techniques in order to maintain as safe and stable working environment as the excavation is in the dry, nevertheless, preventing water pressure from causing damages to foundation formation level(s). In general this can be achieved by physical blocking (e.g. Cut-Off Walls) of the excavation area sides (perimeter) and/or by pumping the groundwater out of that excavation site (e.g. Well Points) forcing the water table to drawdown. The principal methods of groundwater dewatering and control used by the department are:
