Types of Crawl Space Support

We have listed a few different types of crawl space support for details and technical specifications. Use this guide to find out which type of crawl space support you require in your home.

Adjustable Steel Support Jacks: Professionals commonly use adjustable steel support jacks in Brooklyn, Queens, and Long Island for both residential and commercial projects. These jacks provide customizable support, helping to lift and level floors while addressing issues of sagging or unevenness.

Helical Piers for Foundation Support: Helical piers are often employed for crawl space support in these urban areas. These screw-like devices are drilled into the ground to provide stable foundational support, preventing settling and shifting in both residential and commercial structures.

Concrete Piers for Structural Stability: Concrete piers are widely used by professionals in Brooklyn, Queens, and Long Island to provide robust foundational support. These piers are installed beneath the structure to distribute weight evenly, preventing issues such as foundation cracks and settling.

Steel I-Beam Reinforcement: Steel I-beams are commonly utilized for crawl space support in commercial projects. These beams are placed strategically to reinforce and support load-bearing structures, contributing to the stability of larger buildings in urban environments.

Crawl Space Encapsulation with Support Enhancements: Combining crawl space encapsulation with additional support measures is a comprehensive approach often used by professionals. This involves sealing the crawl space and installing support systems like jacks or piers to address various structural concerns while managing moisture issues commonly found in Brooklyn, Queens, and Long Island.

How Does Crawl Space Support Work?

Crawl space support is an essential element in preserving the structural integrity of both residential and commercial properties. Experts utilize a variety of methods to ensure the necessary reinforcement is provided. Adjustable steel support jacks are a key tool in this process, offering precise adjustments for floor leveling and correcting unevenness issues. These jacks are meticulously positioned under the structure to lift and stabilize areas at risk of sagging, seamlessly integrating with crawl space crack repair strategies to address and seal foundational cracks, further safeguarding the property’s stability.

Helical piers represent another critical technique, where screw-like structures are drilled into the ground to offer foundational support. This method is especially crucial in areas like Brooklyn, Queens, and Long Island, where it effectively combats the settling and shifting of the foundation. Similarly, concrete piers play a vital role in enhancing structural stability by distributing the weight of the building evenly, thus reducing the likelihood of foundation cracks and settling — issues that, if left unaddressed, can lead to significant repairs.

For commercial applications, steel I-beams are employed to bolster load-bearing walls, providing an extra layer of support. Moreover, a holistic approach that combines crawl space support with encapsulation and crack repair techniques offers a comprehensive solution. This not only fortifies the structure against physical stressors but also tackles moisture-related concerns by sealing the crawl space and installing robust support systems. This integrated strategy ensures a durable, secure foundation while maintaining the overall health of the crawl space environment.
