Helical Pier
Helical Piers Drilled Into Competent Soil
Helical piles are ideal in situations where push piers may not be indicated due to the depth of the load bearing strata. Helical plates are welded on to a strength testing center shaft which is then "screwed" into the substrate below. This process ensures that the soil integrity remains undisturbed and the structural load is adequately transferred from the foundation to pier and then on to the welded plates below.
