Techno Metal Post U.K. has been contacted by the architect and self-builder to install the foundation of his own carport near South Nottingham, Nottinghamshire. The customer believed that using helical piles must be the right solution as the closeness to large trees leads him to the screw piling. Indeed, the steering of the piles is possible and allow to go around a tree root.
This solution was acceptable to local authorities who would not allow concrete filled trenching so close to my trees.
The helical piles have been installed without any soil excavation. Moreover, it was the best way to protect the roots of the trees, to avoid any damage to the driveway and, by the way, to respect the suitable distance and depth to avoid the risk of the clay heave/shrinkage movement due to moisture variations.
The foundation for this project rests on eleven helical piles, 2,1 meters in depth, to ensure the carport is properly founded and anchored. The whole installation has been completed in 4 hours.
As soon as the Techno Metal Posts were installed, the customer was able to immediately begin and self-build the oak wood structure.
The customer confirms: All the trees are still thriving, I was very pleased with the piles you installed and the service you provided.
