Why Use Displacement Piles?
Are you wondering how best to lay the foundations for your next building project? If you’re hoping to minimise congestion onsite and reduce the amount of spoil material generated during the construction process, it may be worth considering displacement piles.
What Are Displacement Piles?
Displacement piles represent a method of pile boring that does not require soil removal. It involves the use of specialist drilling tools that displace soil laterally in the direction of the bore walls. Once the displacement pile operation is completed, the drilling tool and string are extracted from the ground and fresh concrete is poured via an internal hollow pipe. This concrete is then reinforced using a steel cage to ensure maximum strength and longevity.
What Are The Advantages Of Displacement Piles?
An increasing number of project managers, architects, construction professionals, and housebuilders are selecting displacement piles as their preferred method of piled foundation.
Reasons Include:
1. Minimum spoil material generation
Only around 1.25m² of spoil material is created per 450mm-diameter pile. This means that fewer workers are needed on-site to clear excavated spoil and therefore congestion is reduced, thereby speeding up the building process. With landfill and muck away costs increasing year on year this system is the system of choice.
2. Minimal vibration during the execution of piles
Minimal vibrations mean work is minimally disruptive and as quiet as possible, reducing the burden on surrounding residents and workers.
3. Higher bearing capacity compared to large diameter bored piles and continuous flight auger piles
This is good news if you have a large job on your hands that requires urgent completion.
4. Reduced concrete consumption
Displacement reduces concrete overbreak, Reduced concrete means you can save money and the planet while avoiding wastage.
5. An impressive daily production rate
Displacement piles are suitable for users keen to improve the efficiency of their pile design, speeding up the foundation laying process and improving surrounding ground strata.
6. The piles are delivered by medium-large-sized rig models
The rigs used in displacement piles are robust and capable of carrying out even the most challenging of jobs on different types of soil.
