The Amity Harbor Helical Pile Project

This project in Amity Harbor was unique because the engineering company (Havelin Engineering) specified that the existing block foundation and footing could be used. 

This would not only save time but also save the homeowner unnecessary expense. Before the existing foundation and base could be utilized, it would have to be supported by 20 local piles. 

To secure the footing and ensure that the current footing could handle the extra weight of the new higher foundation installed on top of the existing block foundation after it was reinforced.

Reinforcing A Block Foundation

Although in good condition, the block foundation would have to be reinforced with additional rebar. The blocks themselves would have to be filled with grout. The blocks were then filled with 3000 PSI grout to provide additional capacity and support the extra weight of the new elevated foundation.

Reinforcing a block foundation is a crucial step in ensuring the stability, durability, and longevity of a building. Block foundations are standard in many construction projects, but they may require reinforcement for various reasons, such as structural weaknesses, settling, or the need to support additional loads. Here’s an overview of the process involved in reinforcing a block foundation:

1. Inspection and Assessment:
Begin by thoroughly inspecting the existing block foundation to identify any structural issues, cracks, or signs of settling.
Assess the soil conditions around the foundation to determine if any soil stability or drainage issues may have contributed to foundation problems.

2. Engineering Analysis:
Consult with a structural engineer or foundation specialist to conduct a detailed analysis of the foundation’s structural integrity.
The engineer will assess the type of blocks used, their condition, and the load-bearing capacity of the foundation.

3. Design a Reinforcement Plan:
Based on the assessment and engineering analysis, the specialist will design a reinforcement plan tailored to the specific needs of the block foundation.
This plan may include adding steel or reinforced concrete elements, installing additional support piers, or utilizing a helical pile system.

4. Foundation Excavation (if necessary):
Depending on the reinforcement plan, excavation may be required around the perimeter of the foundation to access the areas needing reinforcement.

5. Installation of Reinforcement Elements:

 Reinforcing elements, such as steel beams, braces, or piers, are installed according to the engineered plan.
Steel beams or braces may be anchored into the foundation walls to provide lateral support.
Piers or piles may be installed beneath the foundation to provide additional vertical support.

6. Connection to Existing Foundation:
Reinforcement elements are securely connected to the existing block foundation to ensure a stable, load-bearing connection.
Proper anchoring and fastening techniques are employed to prevent movement or separation.

7. Grouting and Backfilling (if necessary):
– In some cases, grout or concrete may fill voids and stabilize the soil around the newly installed reinforcement elements.
– The excavation is then backfilled and compacted to restore the site.

8. Quality Control and Testing:
The reinforced block foundation is inspected to ensure all components are correctly installed and meet engineering specifications.
 Load testing may be conducted to verify the strength and stability of the foundation under expected loads.

9. Documentation and Compliance:
Documentation of the reinforcement work, including plans Compliance actions, and testing results, is provided to the property owner and the relevant authorities to ensure compliance with local building codes and regulations.

Reinforcing a Compliancedation is a specialized construction project that experienced professionals, including structural engineers and contractors, should carry out. Helical Piles of New York worked with the Havelin Engineering Company during this Amity Harbor Project.
Proper reinforcement not only strengthens the foundation but also enhances the overall structural integrity of the building, ensuring its safety and longevity.

Amity Harbor Helical Pile Project RequiredUnderpinning with Helical Piles

The underpinning was accomplished by using Chance Helical piles and Chance foundation brackets. The brackets were attached to the existing footing, and 20 helical piles were installed to meet the required capacity of 12 tons.

Underpinning with helical piles is a proven method for stabilizing foundations and preventing further settlement or damage.

It is often chosen for its speed, minimal disruption, and adaptability to various soil conditions, making it an efficient and reliable foundation repair and reinforcement solution.

Supporting A Fireplace and Chimney

Three more helical piles and pile caps were installed to properly support the existing fireplace and chimney, which the owner insisted be preserved.

Helical Piles of NY

Helical Piles of New York installed all helical piles and grouted the existing block. They also did the 5-foot poured concrete additional foundation to raise the home 2 feet above the required flood levels of this area. All this work was accomplished in half a day, which is just another benefit of hiring a company that installs helical piles and a concrete foundation expert.
Helical Piles of NY is a division of High Rise Industries Inc., a family-owned and operated reinforced Concrete and Excavation Company specializing in a wide range of concrete construction services. From reinforced concrete footings and piers to factual underpinnings and poured foundations.
