CFA/Secant Piles/ Grout Injection Piles
MGI has the capability of constructing grout injection piles from 300mm to 1200mm in diameter and up to 20m in depth. We construct either individual grout injection foundation piles, contiguous pile walling or secant piled walls. The vast majority of our grout injection piling is carried out in sandy or wet soil conditions in which grout injection piles are specified to prevent the holes from collapsing. We have five grout injection rigs ranging from a 20t mini rig for restricted access situations to our 60t drilling rig. Our grout injection rigs are capable of drilling into low and medium strength rock.
