Helitech CCD provides custom foundational services for deep foundations. Deep Foundation services transfer structural loads through to competent soils or rock when shallow foundations are not feasible due to weak, compressible soils near the ground surface.
There are many reasons why our team might recommend deep foundation services over shallow foundations. It all depends on the structure you need to build, the kind of support you’ll need, the type of soil at shallow depth, and any site constraints you might have (such as property lines or building codes).
Deep foundations are typically connected to the structure and can be built beforehand or attached as an underpinning element afterward. Deep foundations can be made from timber, steel, or concrete, and they can be constructed by driving piles into the ground in a situ or through excavation and drilling.
Helical Piles, sometimes referred to as anchors, piles, or screwpiles, are often used to stabilize new or existing foundations. Helical piles essentially look like screws — they’re comprised of one galvanized iron shaft with “fins” or helical bearing plates. These piles are then turned into the ground by a machine to the desired depth.
Micropiles are an excellent for deep foundations because they don’t require any pre-drilling. As a result, they’re often used to repair existing foundations to create a stronger and more stable soil rather than replacing a foundation. They’re also typically used to stabilize adjacent structures that could interfere with your project’s stability.
Resistance piles — also known as push, pipe, or friction piers — are hydraulically driven systems that were initially created to address building settlement problems. These piles are “pushed” into the earth using hydraulics until they reach stable soil. Resistance piles are meant to handle the heaviest structural loads and are best used when it’s difficult to assess the condition of the soil.
