The Sandy Solution® Using the CHANCE® Helical Pile Foundation System for Coastal Flooding
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 Pier and Pipe Piling Foundation 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 structurally superior, cost-saving, spoil-free, environmentally-friendly, and installs easily in high water tables.
The CHANCE® Helical Pier Foundation System creates secure, deep foundations that continue to support your structure even after storm scouring occurs in FEMA V-Zone areas. There are several helical pile foundation options to choose from. Helical options include:
- Retaining and underpinning your existing foundation. This choice depends on the integrity of the existing foundation.
- Helical piers below grade supporting a grade beam while posting up to elevation using concrete block, wood, or something else. This is a more traditional helical approach. It is popular with some design professionals and cost effective.
- The patented CHANCE® Helical Pulldown® Micropile (HPM): a combination pile, end-bearing on the lead shaft’s helical plates while transitioning to grouted helical extensions. The cased pile replicates a timber pile and posts up to elevation.
In addition to cased or uncased versions of the Helical Pulldown® Micropile, CHANCE® offers solid bar square shaft, hollow pipe piles, and square shaft to pipe combo piles – all with varying bracket terminations and above grade options.

The Sandy Solution™ utilizing the CHANCE® Helical Pier Foundation System was developed by DANBRO’s Structural Engineer, Steve Gencorelli, P.E., who was named a Civil + Structural Engineer Rising Star for his Sandy Solution designs. The HPM Sandy Solution™ was successfully tested by DANBRO Distributors and Hubbell Power Systems. (Read the Lateral Load Test Report here.) The findings are being used as the basis for many CHANCE® Helical Pile Sandy Home Elevation projects.
