Our additional services
In addition to our core capabilities in undertaking ground engineering challenges we are also able to provide the following services to the industry at our facility.
Kelly bar servicing
The success of any Piling contract comes down to a number of factors, one of the most important is the equipment used. Expanded Piling with Select Plant Hire undertake Kelly Bar servicing on all bars prior to their use. As part of the service a full video is taken as the bar is fully extended and all joints inspected. We conduct this service on all of our own Kelly bars, however this service is also available to external clients in the wider Piling industry.
Pile extraction
Expanded Piling has developed a unique method for extracting existing piles in urban areas where new structures clash with existing foundations. This system is less disruptive than traditional coring, avoiding noisy hour restrictions and providing programme certainty. It effectively addresses the increasing need to manage existing piles in urban projects and has been successfully applied in numerous projects over the years.
Operator training
Training our people and supporting the growth of our colleagues is key to Expanded Piling. Within our Grimsby Depot we are able to train operators to gain A48 Piling Rig CPCS status. Our approach includes training operators in the equipment in a controlled environment under the supervision of our experienced operators.
