Chance Helical Pulldown Micropile

The CHANCE Helical Pulldown Micropile works two-fold to develop capacity. Utilizing capacity gained by the end bearing on the helices and the skin friction developed by the grout column, the Helical Pulldown Micropile can develop both Tension and Compression capacities in upwards of 200 ton (400 kip). The grout column is delivered using the grout's own hydrostatic pressure head and fills in the void created by the displacement plates as the helical pier is "screwed" into the soil.
