About US

Putting steel in ground with passion since 1999.

Based in Pleasantville, New Jersey SJHP began as a certified installer of A.B. Chance helical piles and grew into a multifaceted geotechnical construction firm to meet the growing needs of the construction industry. With strict adherence to safety and zero liability claims we continue to lead the industry in compliance to OSHA standards.
Today SJHP operates in several states for leading clients involved in foundation support, subsurface piling, environmental remediation, load testing and value engineering.



SJHP has over 19 years of in the field, hands on experience driving a variety of piles, building walkways and general construction. From a single pile job to support a residential porch to the famous Asbury Park Boardwalk; we build it right, no matter what.


Safety is our number one priority and our record shows just that. Zero accidents and zero liability claims. Our employees are OSHA trained and certified with regular refreshers. Safety meetings are held each morning before the start of work to insure total compliance. A clean, safe worksite is mandatory at SJHP.


Sometimes it’s important to be able to switch gears during a project. Dealing with the subsurface environment can present unknown challenges no matter how much pre-construction investigation has been completed. At SJHP we understand our client’s needs and go the extra mile every time.

Technological advancement

When choosing a contractor it is important to know that their equipment is state-of-the-art. We use only the best of the best and we own our equipment. We supply certified documentation of calibration to be able to prove that our means and methods meet and exceed the client’s requirements.

Competitive prices

Our prices are based on what the project will cost us and a little extra for profit so we can invest in the future and pay our employees a living wage. The advantage that we offer is prompt service, outstanding workmanship, fast turnaround time and ethical business practices.

Information related to Hurricane Sandy remediation work.



Rockaway Beach, New York

This project involved the installation of 48 A.B. Chance® SS5 helical piles with 10/12/14/14 helix configuration, to the bay floor off the coast of Rockaway Beach in New York.

The purpose was to anchor six experimental wave attenuators that are used to prevent beach erosion. The logistics of the project required the coordination of a barge (with crane), dive team, support boats and SJHP technical personnel.

Pile locations were marked out using marine GPS and helical piles were installed to an average depth of 30’. Proof tests to 6000 lbs. were successfully conducted and the wave attenuators were connected to the piles with custom made floating cables.

  • piles installed: 48 CHANCE® SS5 Helical Piles
  • depth of installation: 30 feet below-grade
Memorial Sloan Kettering Cancer Center, Middletown, New Jersey

The retrofit of a former AT&T building to a new Memorial Sloan Kettering Cancer Center in Mid­­dletown, New Jersey required the excavation of the east side of the main structure to accommodate the installation of back-up, emergency generators.

SJHP installed 22 A.B Chance® SS200 helical piles with heavy duty underpinning brackets and cased them in 6” grouted steel casing. Average torque reached 1,300 ft. lbs.

Due to the subsurface layers of iron-sand and pile depth requirement (50 and 30 feet), pre-drilling was required on both the interior and exterior of the building prior to pile installation. Steel bracing was welded at the critical load points for additional support. Surveyors reported no movement to the structure as the excavation was completed.

  • date completed: November, 2015
  • piles installed: 22 CHANCE® SS200 Helical Pulldown® Micropiles
  • depth of installation: 30-50 feet below-grade
Asbury Park, New Jersey

SJHP submitted the winning bid to rebuild the iconic boardwalk at Asbury Park that was destroyed during Supers Storm Sandy. Two hundred and sixty four A.B. Chance, Pull Down Micro Piles were installed to approximately 35’ below grade and reached a required holding capacity of 80 KIPS (ultimate). The pile installation was completed in three weeks in spite of delays caused by the discovery of an old bulkhead that had been buried for years.

"Once desired depth was achieved, the pile was trimmed to the above-grade desired height. From there, a beam- seat bracket secured each pile to the wooden boardwalk beams. The boards of the boardwalk were then added atop the beams to complete the project.

Led by Art Koziol, President of South Jersey Helical Piers, two installation teams worked simultaneously to install the 264 CHANCE® Helical Pulldown® Micropiles for the foundation of the reconstructed boardwalk. The new boardwalk portion stretched from the Convention Hall on 5th Avenue to the 4th Avenue Pavilion on 4th Avenue."

"This foundation system was chosen for its no-vibration installation due to the proximity of nearby stores, restaurants, and theaters, many of which are glass-faced, and the Asbury Park Convention Center, a national landmark." - Caitlin Haffert in Pile Buck magazine

  • piles installed: 264 CHANCE® Helical Pulldown® Micropiles

Audubon, New Jersey

The purpose of this project was to tie back a platform to support a 500 ton crane used to set modular sections of a new bridge in Audubon, New Jersey. The plans called for A.B. Chance SS225 helical piles with an 8/10/12/14/14/14/14 helical configuration and required torque of 150 Kips.

The piles were driven to an average depth of 55’ at an angle of 45 degrees. Soil borings indicated that the subsurface conditions consisted of clay which necessitated the use of multiple 14” helices to achieve holding capacity. At the completion of the installation SJHP load tested all the piles and submitted the successful results to the client.

University of Pennsylvania, Philadelphia

SJHP was contracted to construct a tieback wall to support higher elevation structures during pre- construction excavation at the University of Pennsylvania’s downtown campus. Engineers choose this system because of the lack of vibration during the installation of the helical piles and the close proximity of existing structures. Soldier beams consisted of A.B. Chance SS5 Pull Down Micro Piles® in 6” steel casing and grouted.

Fourteen feet of pressure treated timber lagging was added as the site was being excavated. The entire wall was tied back using A.B. Chance SS5 helical piles with 8/10/12 helical configurations and adapters for Dywidag® bars. After the timber whaler was installed the tie backs were successfully load tested to the required holding capacity.

Ventnor City, New Jersey

The Inside Thorofare of Ventnor City, New Jersey is a waterway that is lined with hundreds of homes that were built pre-and post WWII. What makes these homes unusual is that many were constructed partially on land and mostly on water with a majority of the house jutting out into the waterway.
Originally, wood pilings were installed to support the water section of the house but nowadays many of those piles have deteriorated to the point of structural failure. Installation of new wood pilings would not be possible due to the limited access for pile driving.
Demolition and rebuilding of the house would result in a much smaller structure on the land section only due to zoning restrictions that were not in place when the homes were first built.

SJHP devised an innovative and cost effective solution to this problem using A.B Chance SS175 Pull Down Micro Piles® cased in grouted 10” schedule 80 PVC and marine grade lumber beams.
Because the piles had to be machine driven a custom made barge was designed and built specifically to carry the weight of a 10,000 lb excavator and floated beneath the structure for pile installation at low tide.
After the helical pile installation was completed timber beams were installed on specially designed galvanized brackets. These beams, in conjunction with the helical piles now supported the water section of the house. To complete the project the old rotted wood pilings were removed and disposed of.
