How Foundation Jacks Work for Basement Stabilization

A secure home starts with a strong foundation. However, homes in coastal areas or flood zone areas like Long Island, Brooklyn, and Queens often experience foundation settlement due to shifting soil, water damage, or aging construction. Foundation jacks offer a reliable solution to stabilize and lift sinking basements, restoring structural integrity. In this guide, we’ll explore how house foundation jacks, hydraulic foundation jacks, and crawl space jacks work to strengthen and stabilize basements. 

We’ll also give you instructions on how to install them in case you go about it on your own, and some tips and warning signs that we feel obligated to give you as certified, experienced installers who know the ropes and want what’s best for you. Hopefully this blog will arm you with the information you need to make an educated decision about getting 

Understanding Foundation Jacks

Foundation jacks are mechanical devices designed to support and lift sagging basement floors or foundation walls. They are typically installed beneath floor joists or load-bearing beams to restore stability. These jacks are adjustable, making them an excellent long-term solution for foundation issues caused by soil movement, moisture problems, or structural deterioration.

Types of Foundation Jacks

Permanent Foundation Jacks

Permanent foundation jacks are heavy-duty steel supports designed for long-term basement stabilization. They are bolted to the foundation and anchored into solid ground, ensuring lasting strength.

Pros:

• • Provides a long-term solution.

• • Effectively stabilizes sagging floors and walls.

• • Prevents future foundation shifting.

Cons:

• • Requires professional installation.

• • Higher initial investment compared to temporary jacks.

2. House Foundation Jacks

House foundation jacks support the main structural components of a home, including basement beams, floor joists, and crawl spaces. They are ideal for lifting and reinforcing homes that have started to settle unevenly.

Pros:

• • Adjustable to provide precise leveling.

• • Prevents further structural damage.

• • Can be used in basements and crawl spaces.

Cons:

• • May not be suitable for severely compromised foundations.

• • Periodic adjustments may be required.

Hydraulic Foundation Jacks

Hydraulic foundation jacks use a pressurized system to lift sunken basement foundations gradually. They provide a more controlled and powerful lift compared to manual jacks.

Pros:

• • Delivers precise, steady lifting power.

• • Works well for homes with significant foundation settlement.

• • Can be used in combination with steel piers for added support.

Cons:

• • Requires professional handling to avoid over-lifting.

• • More expensive than standard jacks.

4. Crawl Space Jacks

Crawl space jacks are designed to reinforce sagging floors in homes with crawl spaces. They work by supporting weakened beams and redistributing weight more evenly.

Pros:

• • Prevents floor collapse and sagging.

• • Adjustable for long-term support.

• • Cost-effective compared to other foundation repair options.

Cons:

• • Limited to crawl space applications.

• • May not be suitable for severe foundation failures.

How Foundation Jacks Are Installed

1. 1. Foundation Assessment – A professional examines the basement or crawl space to determine the cause of the foundation issue.

1. 1. Placement Planning – Engineers map out the optimal locations for jacks to ensure maximum stability.

1. 1. Installation of Jacks – The jacks are placed beneath load-bearing beams or floor joists and gradually adjusted to lift and support the structure.

1. 1. Final Adjustments – Once the desired stability is achieved, the jacks are secured, and any necessary repairs are made.

Why Homeowners in Long Island, Brooklyn, and Queens Need Foundation Jacks

Homes in the New York metro area are vulnerable to foundation problems due to:

• • Sandy, shifting soil that causes uneven settling.

• • Frequent freeze-thaw cycles that weaken basement structures.

• • Water intrusion issues leading to foundation deterioration.

Foundation jacks provide an effective solution to reinforce and stabilize homes, preventing costly damage and maintaining property value.
