Bridge Piers

Straits Crossing, Prince Edward Island - Canada
Straits Crossing, Canada

Bridge piers are generally set on a number of pads which rest on the bed surface.

Due to the uneven nature of the bed surface and the need for the pier base to be level, each pad requires concrete infill of varying thickness' to be cast between the underside of the pad and the pre-prepared rock bed.

 


Pad & Fabric Formwork Ready for Instalation

This is achieved by fixing a Fabriform™ bag to the bottom of the pad prior to its placement (as shown right)

Once the pad has been positioned into its desired location, by crane, the Fabriform™ bag is pump filled with Micro Concrete, this ensures that a good, even seal to both the bed and the pad is achieved (as can be seen in the Trial photograph below).
