Piling is a type of ground treatment which is driving a pile into the ground below ground level. Except sheet pile, other piles like concrete pile, timber pile, steel pile, bored pile are used to transfer the building load to the ground. It’s used to strengthen the soil so that the ground able to support the load of the building. While sheet pile is usually used to support lateral load and act as a supporting wall.

There is a lot of different types of piles in the market, many other type of piles have been occurred in the market and still increasing due to improvement of piling technology. Driving method, type of piling machine, procedure of piling are all take into consideration in choosing type of pile.

Length Of Pile

Normally the length of the pile can be 3metres, 6metres, 9metres and 12metres. The depth of piling to be driven into the ground is depending on the condition of ground. If a length of 3m, 6m, 9m, or 12m pile is not enough to support the load of building, another 3m, 6m, 9m, or 12m pile will be joint to the first pile and continuously until it’s strong enough to support the load of building. Or so, the first pile or we called it as “starter pile” will be driving in until it can’t be driven in anymore.

Precast And Cast-In-Situ Pile

Pile can be done in precast concrete pile or cast-in-situ concrete pile. Normally precast concrete pile is used for building work or we can known it as spun pile or RC square pile (Reinforcement concrete square pile). While cast-in-situ concrete pile is used for bridge work or we can known it as bored pile because bridge work has a larger load compare to building work.

Nowadays, piling work is an important ground supporter and is a must to be used on construction unless the condition of soil is hard and strong enough to support the load of building.
