The Sandy Solution™ Using the CHANCE® Helical Pulldown® Micropile for Coastal Flooding
FEMA-Compliant Deep Foundations for the V- and A- Zones
Superstorm Sandy packed quite a punch leaving many in New Jersey, New York, and New England in vulnerable situations. FEMA has provided guidelines concerning repair options and compliance with Flood Zone Areas. (For more FEMA information, visit www.fema.gov.)
The situations in these shore towns are unique. There is limited-to-no room for moving houses off of properties, which is necessary to drive the typical timber piles needed to raise a house. That is why the ability to lift a home vertically while the foundation work is done below is necessary, and the CHANCE® Helical Pulldown® Micropiles and Pipe Piling Systems are ideal.
Small installation equipment is used to fit in tight access areas or under raised homes with minimal clearance. The helical pile installation causes no vibrations that could damage you or your neighbor's properties. The helical pier system is spoil-free, environmentally-friendly, and installs even with high water tables.
Cased Helical Pulldown® Micropile
The Helical Pulldown® Micropile (HPM) is used to form a grout column around the shaft of a standard helical anchor/pile. The installation process can employ grout in combination with either steel or PVC casing.
To begin the process, a helical anchor/pile is placed into the soil by applying torque to the shaft. The helical shape of the bearing plates creates a significant force that keeps the foundation advancing into the soil. After the Lead Section with the helical plates penetrates the soil, a Lead Displacement Plate and Extension are placed onto the shaft. Resuming torque on the assembly advances the helical plates and pulls the displacement plate downward, forcing soil outward to create a cylindrical void around the shaft. From a reservoir at the surface, a flowable grout immediately fills this void surrounding the shaft. Additional extensions and displacement plates are added until the helical bearing plates reach the minimum depth required or competent load-bearing soil. This displacement pile system does not require removing spoils from the site.
Scoured but Still Standing
Exposed helical piles securely support a pool and structure in Southhampton, New York, after Hurricane Sandy scoured the sand from underneath the structure.
