4SP Group has years of experience and has plenty of resources, skills and expertise to assist in projects of all kinds from conception to completion. Our professional team is involved in the successful installation of piles using various methods and techniques. With the joint effort of our team, we provide great products, excellent service and management across the construction sector.
Our bored pile foundation is typically used for the foundation to withstand strong, vertical loads. It transmits the weight to the rock layers with appropriate bearing capacity and reduces the structural settling. We have divided the bored pile construction into two phases; drilling and construction. Under the supervision of open bored piling contractors, our team firstly removes soil during the drilling phase to make a hole of desired depth and diameter, while reinforced concrete is poured in situ during the construction phase.

Open bore piling being used for years, is utilised both by small and large-scale construction projects with varied types of ground substrate. Our piling company provide integrated steel and concrete solutions producing less vibration, making it retrofit for all kinds of building structures.
Open bore piling works well with cohesive soil. Our advanced augers are driven into the strata while reaming out the soil. Once the desired depth is reached, augers are removed, leaving an open hole. We use steel reinforcement for strong and firm foundations before pouring the concrete.
Our advanced rigs are cost-effective for usage on wide open sites with cohesive grounds, as well as chalk and some sands. Smaller models are appropriate for interior use. Because rotary augers produce less vibration, they are appropriate for usage near buildings or subterranean services. It is also feasible to use these rigs for down-the-hole hammer drilling, which allows piles to be secured in rock or dense material.
Rotary bored piling removes debris and dirt using state-of-the-art rigs and specialised drilling equipment such as buckets and augers. Our bored piling contractors use the tools to repeatedly dig the earth, eliminate soil and insert piles to the desired depth.
When the ground condition is weak, a temporary and permanent casing is employed to allow the piles to be bored without collapsing the earth. The ground is unstable along the whole pile length due to groundwater incursion or deeper lose ground. Our professionals use full-depth casing or drilling fluid to level the ground.
Following are the main benefits of bored piles or drilled shafts when compared to conventional footing or other types of piling.
