Mircropiles are small diameter piles, generally 300mm or less in diameter, and may be useful for carrying (a) small compression loads or (b) uplift loads or (c) for earth retention where enough area is not available for normal earth retention systems. Micropiles may also find use in low headroom applications. Ammico has extensive experience in installation of micropiles in various types of ground conditions.

Soil nailing and shotcreting may be an economical solution for stabilization of rock excavations against local failure in medium to strong rocks where such rocks are generally stable under a vertical cut or under a slope close to vertical. Jet grouting can be a useful method for ground improvement in certain types of soils.
