Pieresearch Centraligner™ Pier Sleds

Pieresearch Centraligner™ Pier SledsRebar cage alignment in drilled shafts, drilled piers, caissons, cast-in-drilled-hole piling and cast-in-place pile.

Without proper alignment, the rebar cage cannot perform the function for which it was designed. Proper positioning helps protect against long-term corrosion of the rebar. Faulty alignment can cause foundation failure, which often leads to issues of contingent liability. Because the rebar cage cannot be inspected or tested after the concrete is placed in the drilled shaft, the cage must be aligned properly the first time.

Often spacers, such as rocks, bricks, or sticks are used in an attempt to properly space the cage within the shaft. Usually these devises fail to stay attached to the cage and tend to gouge the side of the shaft, causing debris to clutter the shaft's floor.
PIERESEARCH has developed a solution to these cage-positioning problems consisting of two 7,500 psi high-strength grout devices, the Centraligner® Pier Sled and Hijacker® Pier Bolster.

Centraligner® Pier Sled contains a notch for the spiral or circle tie and has four sets of integral, embedded 16 gauge galvanized wires for ease of installation. The sled's shape prevents the cage from hanging on the casing and it doesn't protrude into the interior of the cage so interference with the tremie is not a concern.

These products have been well received by the structural engineering and construction communities. They achieve a result that has long been sought by structural engineers.
To order, call PIERESEARCH for current pricing, give quantity, size and name. PVC coated tie wires are available on special order.
