Square Tubular Shaft Helical Piles
Helical piles,also known as anchors, piers or screw piles, are deep foundation solutions used to secure new or repair existing foundations. Due to their design and ease to install, they are most commonly used whenever soil conditions prevent standard foundation solutions. Instead of requiring large excavation work, they thread into the ground. This minimizes installation time, requires little soil disturbance, and most importantly transfers the weight of the structure to load bearing soil.
Helical piles have been used all over the world to secure residential and commercial buildings. Originally designed for lighthouses they are widely used for many other deep foundation applications.
