Yellowhead Overpass Retaining Wall

Often, screw pile installation equipment is not the only type of equipment required to complete a foundation package.  There are almost always welding requirements, and often hydrovac requirements as well to ensure the screw piles are being installed in a safe location free of underground utilities.  Reaction provides services for the design, supply, fabrication, and installation of screw piles as well as associated scopes of work such as welding and hydrovac in our other divisions.  For a number of projects all divisions work together providing the client with a one stop shop for their foundation and earth work requirements.

One such project was a retaining wall in Edmonton, AB.  Reaction was presented with a requirement from the client to install large diameter piles to form a timber lagging and screw pile retaining wall system to allow for safely widening the road.  This had to be done quickly, as the client was waiting for this structure to be completed before continuing with their scope.  Reaction worked together with the client to come up with a screw pile segmented install procedure to allow for the use of one of our larger rigs underneath the low overpass.  Reaction provided all parts of the wall from the screw pile installation including the welded connections, to the hydrovac trenching of the soil for the timber lagging and the construction of the lagging between the piles.  Working around the clock, Reaction was able to complete this project to the tight schedule requirements of the client and allow them to continue the road widening safely with minimal delay.
