Micro-Aid SP is an admixture designed specifically for use in soldier pile grout. It provides all of the properties required for soldier pile grout: improved workability, water retention and strength reduction. Fluid grout is easy to pump and place. Water retention keeps the mix water in the grout, so it stays fluid long enough to drop steel beams, even in challenging, sandy, free-draining soil conditions. Strength reduction is the product of the low cementitious content and 10-15% air generation which can reduce strength to under 500 psi. Micro-Aid SP is the all-in-one solution for challenging soldier piles.
