New Construction

As a region sees more and more development, there is more construction on marginal sites. Suitable bearing soil may only exist at depths greater than normal. Adjacent structures may preclude the use of H-Piles or poured concrete foundations. Foundation designers may also need to consider potential problems related to access and site conditions.

Helical Pier® Foundation Systems manufactured by CHANCE® offer an excellent solution to many of these problems. They can provide anchor capacity for building structures and towers subjected to wind loads and can be used in bearing applications for new foundations.

Other applications for helical products include foundation support for signs and light standards, slab underpinning, and column underpinning. Drilled micropiles are ideal when higher capacities are needed. This system is excellent in urban areas or sites with limited access. Learn more about micropile systems.

Design for these micropile and helical systems should include professional engineering input and site specific soil information. The design for ultimate and allowable bearing or anchor loads is established by classical geotechnical theory, supplemented by empirical data developed from field load tests.
