After the metal is set into your drill hole it can be encased in concrete, This can be what makes the power of the pile. Not like other larger diameter piers, the power of the micropile will come totally from the grout to soil bond or “side shear”.
Alternatively, any other ideal system which include filling the bore with coarse mixture up to the desired height of about 1m and filling it subsequently with cement grout can even be proposed.
