There are basically two major types of foundation repair – the shallow and deep foundation repair. Despite of the repair class, repair is very vital for your home’s life as well as your family’s safety.
What is a Deep Foundation Repair?
A deep repair of your foundation is also known as the underpinning, mostly involve screwing or pushing steel piers into the surface in order to transfer the lift structural elements and support of the foundation. In addition to that, the deep repair is the most commonly used for lifting concentrated weight loads like the footings and also for bypassing the unstable layers of the soil that are only causing recurrent issues with the foundation. As a matter of fact, deep foundation repairs include the transferring the weight of the foundation to various layers of the surface on which it was initially constructed.
Foundation Repairs Using Helical Piers
The helical pier is actually a steel shaft with spherical helix plates which provides the foundation support for different types of buildings. When the helical pier is rotated in the ground, its helix plates produces an axial thrust which causes the pier to move forward into the ground like a screw into the wood. Aside from that, a bracket is placed to the pier and foundation wall that allow us to support and stabilize the foundations which have heaved, settled or even failed to operate as basically designed. The helical piers are most likely the choice of most professional structural engineers and expert Tampa foundation repair for lightly-loaded and older structures. On top of that, the helical piers become the better substitute to the conventional concrete caissons for new applications in both the commercial and residential projects.
Furthermore, the deep-driven steel helical pier is usually 2-7/8 inches or 2-3/8 inches in diameter sectional pipe piles as well as are rotated into the ground with extreme water pressure in order to bear on a solid soil stratum or a rock. The piles are produced from the high-powered carbon steel tubing with the ideal lengths of 3 feet, 5 feet and 7 feet with some couplings one the edges which allow them to be attached together in order to achieved the ideal depth. They’re coated with polyethylene copolymer-based thermoplastic fine powder coating to protect corrosion.
Installation of the helical piers is a more efficient, faster and easier process. There is lesser noise, excavation and also, may be installed outside or inside your house. As efficient as these helical piers are, still there are some limitations.
The primary disadvantage is its system’s dependency on the existing soil. The helical piers use the existing soil to place and pull the pier. The experts on home foundation may keep adding extra shafts to the pier in order to reach the ideal depth. On the other hand, the bedrock is not important however, reaching a stable, the high-density stratum is.
In addition to that, another limitation to the helical piers installation is space. The helical piers have conventionally needed a lot of workplace in order to install.
