AB Chance helical piles for environmental boardwalks and bridges through marshes, bogs and wetlands
Helical Pile s for Boarwalks Brochure

We are quickly becoming aware of the concerns to protect our environment and ecological development.  When it comes to building or constructing helical pile foundations in sensitive areas such as wetlands, marshes, bogs, beach or lake fronts, AB Chance helical pier foundation systems have been recommended as a safe approach to constructing with minimal impact to the ecological habitat.  We have worked with audubon societies and conservation commissions to build boardwalks, docks and bike or hiking trail bridges that pass through wetlands.  Have a look at the brochure on this page that offers technical information on  helical piles for nature trail footbridge/boardwalks.

It's proven most economical in sensitive soils and difficult terrain.  The galvanized steel anchors are pre-engineered to transfer projected loads to bearing-capable layer beneath the soft silty soils.  This isolates the structure's integrity from seasonal changes in the surface-layer conditions. If you're dedicated to protecting the ecosystem in wetlands, you need to consider the proper construction method to install your pedestrian trail bridge.
