What you need to know when looking for a piling contractor
Piling is a specific trade in the construction industry and is essential to building since it creates the support or base needed for a structure to stand. This is done by setting deep foundations in the ground for any form of construction work. Wood, steel or concrete can be used for piling. It is important to choose the materials you will use for piling because you need a sturdy foundation for your structure.
What to consider when hiring a piling contractor
Piling deals with the ground where a structure is going to be built on, so it is important to have a full understanding of the ground conditions on site. Contractors need to have sufficient knowledge of geotechnical reports (or soil reports) in order to be able to fully assess the land that they will be handling.
Once the ground has been assessed, it's time to pick the type of piling to be used. Below is a list of different piling types:
- Screw - also known as a screw pile, this involves huge screw-like pipe or pole which is drilled on to the ground.
- Sheet piling - instead of pipes, huge steel sheets are driven into the ground. This helps with earth retention and is mostly used as an excavation support technique.
- Bored piers - this involves digging out (or boring out) a hole on the ground, then filling this hole with concrete.
- Anchoring - this is done by driving a pipe at an angle instead of straight down the ground.
- Driven piles - this is the most basic type of piling with pre-formed piles made out of steel or concrete.
- Friction piles - this type of piling needs a lot of contact between the soil and the pile. This usually runs long and deep into the ground.
- CFA (Continuous Flight Auger) - this uses a continuous flight auger drill which drills the ground while taking out the soil without removing the auger from the hole. This type of piling is quick, cheap and is the quietest compared to other types. CFA is usually utilised on loose ground.
Equipment used in piling
Piling utilises a number of equipment, including the following:
- Impact hammer or Pile driver - a type of equipment which uses a pounding motion to drive a pile or pipe into the ground.
- Vibratory hammer - with the use of vibrations, this equipment loosens the soil while driving a pile into the ground which reduces the resistance of the ground, making it easier to drive the piles in.
- Drills - a type of equipment that drills holes on the ground where concrete is poured in to make a pile.
How much would it cost to hire a piling contractor?
