We offer the design and installation of the following ground engineering techniques.
Our designs are carried out by qualified, experienced engineers to comply with the current codes of practice and standards as appropriate to the contract. Our techniques ensure we focus on safety and quality. Using our specialist minipiling rigs, we can adhere to your project-specific restrictions and deliver on your requirements.
Drilled micropiles are constructed using bespoke hollow-threaded steel bars that are simultaneously drilled and grouted. These piles are generally between 150 mm and 300 mm in diameter and installed using powerful minipiling rigs weighing between 2.5 and 10 tonnes.
This technique is particularly effective where rock penetration is required or where cobbles, boulders and mass concrete are in the overburdened material. The components are generally between 200mm and 450mm in diameter and installed using pneumatic hammers mounted on minipiling rigs, typically weighing between 4.5 and 12 tonnes.
Rotary bored minipiles are suitable in most ground conditions; therefore, they are the most versatile regarding an engineer’s specification. These components are generally between 300mm and 750mm in diameter and installed using powerful high torque minipiling rigs typically weighing between 4.5 and 18 tonnes.
Piled retaining structures are required for a variety of applications to support excavations for basements and infrastructure in temporary and permanent situations. These structures are generally constructed using rotary bored or drilled techniques in a contiguous or secant configuration or in a king post system.
