Grout Injection Push Pier
Hydraulically Driven Push Piers Combined with Compaction Grouting
Our injection underpinning push piers are the perfect union between compaction grouting and our standard push piers. These piers are initially pushed to bedrock, sufficiently supporting the weight of the structure. Grout is then pumped through the machined threaded hole in the bracket top plate and into our patented perforated pipe, allowing grout to flow out, filling voids and compacting surrounding soils, securing the pier in place.
