Advantages To Our System:

At AFS Foundation & Waterproofing Specialists, we recommend installing the SettleStop Floor Support system, which uses adjustable heavy duty steel crawl space jack posts. These posts install quickly in a home and provide the best solution for restoring stability to your structure.

The SettleStop Floor Support system can be installed in tight conditions, usually in less than a day. Made with galvanized steel for corrosion resistance, it can support vertical loads exceeding 60,000lbs.

The adjustable design of our crawl space jack system means that sagging floors can not only be stabilized; they can also be restored their original position in many cases.

To address the issue of poor supporting soils, each crawl space jack distributes the weight of the home through a precast concrete footing and a base of engineered fill material.

The SettleStop Floor Support is the only solution that addresses problem soils during crawl space restabilization!

Installing the SettleStop Floor Support

Installing the SettleStop is a fast process that will not disrupt your home or landscaping. During our crawl space repair, your installers will follow these five steps:

Preparing For Installation

Before the installation, a system design specialist will meet with you to design a crawl space support system that will effectively return your home to structural stability. Our specialist will also be able to explain our system and answer any questions you may have about your crawl space repair.

The location for each crawl space support jack will be mapped out for your installers when they arrive, ensuring a proper installation.

At the beginning of the installation, our team of in-house crawl space repair contractors will excavate a 2′ square, 2′ deep hole at each SettleStop location. Each of these holes will be prepared with engineered fill consisting of tightly compacted crushed stone.

Placing the Pre-Cast Footing

A pre-cast concrete base (or footing) is placed on top of the engineered fill and carefully leveled.

The footing serves as a stable base for the steel jack post, keeping it vertical and distributing the weight bearing on the post across a broad area of soil. The engineered fill base underneath the footing provides solid support that won’t shift, settle or be affected by soil moisture. Some building codes may require a poured concrete base rather than engineered fill.

By the time the weight is distributed through the pre-cast base and the fill, the bearing stresses have dissipated to approximately 10% of the stresses at the top of the post. This means that even if you have weak supporting soils, you can be assured that the weight of the building will not exceed their bearing capacity.

Customize Floor Support

Once new bases have been installed, measurements are made for the steel crawl space floor supports, and the posts are cut to length.

Once the SettleStop Floor Support has been installed in your home, you can rest assured that you’ve invested in a high-quality, permanent solution for your crawl space issue.

Assembling & Tightening

Each crawl space floor support is assembled in your crawl space. The top of the crawl space jack is mounted against the girder, and the installation is carefully plumbed.

In cases where existing girders are undersized or damaged by rot, a new sister girder may be installed alongside the original in order to strengthen and reinforce the structure.

Each SettleStop Floor Support is then tightened in an attempt to lift the floor back to its original position. In many cases, your contractors will be able to straighten and level floors, close cracks in walls, and halt future downward movement. The jacks will continue to be adjustable for future tightening, should you need it.

Encapsulating The Crawl Space

If your wood crawl space joists, girders, and/or supports were damaged by mold, rot, and moisture, then you will want to address these issues to prevent future damage.

The encapsulation process involves sealing all crawl space vents, installing an airtight crawl space door, and lining crawl space walls and floors with a durable plastic liner. This treatment can also include additional drainage measures like installing interior drains and a sump pump.

Encapsulation stops moisture-related damage and associated structural problems that occur when framing members rot and deteriorate. By investing in crawl space encapsulation, you’ll also improve overall home energy efficiency and indoor air quality.

Some homeowners and contractors will attempt to use concrete blocks to repair a sagging crawl space, with wooden “shims” wedged in at the top to fill in any empty space.

This kind of installation is a short-term solution that requires constant maintenance and reshimming. And because your concrete columns will continue to sink into the earth below, this solution will ultimately fail.
