Slab push piers work like any resistance end-bearing pier in that it does not rely on skin friction to produce support. Much like with any structure installation, the entire slab acts as the reaction force. The resistance slab pier is installed using a grid pattern. After installing the piers, the slab load is transferred across the piers uniformly and evenly by activating the hydraulic rams simultaneously.
When to Use a Resistance Pier Slab
So, when do you use a resistance pier slab? Primarily anytime you have a slab that needs to be lifted and stabilized due to failing soil conditions that are too weak to support the slab. Installation is accomplished inside the structure through an eight-inch core drilled access hole. These piers install quickly due to their minimal set-up time making the resistance slab pier a low cost and time-efficient solution.
