Permanent solutions for reinforcing Joists & Girders, & preventing rot damage
If your home has sagging floor joists and girders, you’re dealing with a problem that manifests itself throughout the entire building.
A problem such as this can be caused by many possible factors, but are usually the result of three common issues:
- Inadequate Supports: The support system under your home has too few support posts to hold up the structure.
- Weakened Floor Joists & Girders: Moisture, rot, termites, wood-boring insects, or other destructive forces have damaged your structural wood.
- Support Settlement: Weak supporting soils underneath the basement or crawl space supports have caused these supports to sink into the ground.
Symptoms of Sagging Floor Joists & Girders:
Problems related to inadequate floor joist bracing can show up all over the house, including the following:
- Sinking/Uneven Floors
- Springy Floors Underfoot
- Cracks Forming On Interior Drywall
- Jamming/Sticking Interior Doors
- Moldy Floors
- Sinking Crawl Space or Basement Supports
What’s Damaging Your Floor Joists & Girders?
If Mother Nature is the cause of your damage, there can be many possible forces hard at work on your basement or crawl space’s structural wood. Determining which one you’re dealing with can be difficult to do!
Sometimes, a wood surface can be virtually covered in mold, but will still show little evident structural damage. In other cases, the wood may appear to be strong and untouched, while subterranean termites have hollowed the wood out from the inside.
Before you can consider a permanent repair for your basement or crawl space, you will need to address the moisture and humidity that feeds mold, rot, pests, and other unwanted forces. The key to this is to keep your below-grade space dry by installing a vapor barrier system and by running a powerful dehumidifier system.
Reinforcing Joists & Girders
Compared to other sources of structural damage (frost heave, foundation settlement, bowing foundation walls, etc.) it’s relatively easy and inexpensive to reinforce joists and girders in a structurally damaged crawl space or basement.
Girder and joist jacks (also known as “steel lally columns”) can be installed at key locations along the structure. Once in place, the floor can be “jacked up” in an attempt to lift the floor back to a level position. If a contractor finds a joist is severely damaged, a sister beam can be installed alongside the normal one for extra strength.
At Baker’s Waterproofing, we’ve seen just about everything! Below are just a few of the sagging floor joists the experts have encountered:
Floor Joist Jacks for Below-Grade Spaces
Crawl space and basement joist supports are steel, adjustable support posts that are installed to repair sagging floors.
These reinforcing joists install quickly in below-grade spaces — with a complete installation taking about a day — and provide a permanent solution.
Our SettleStop IntelliJack™ Support System is designed with corrosion-resistant galvanized steel, ensuring that it will be strong and adjustable for decades to come. A unique base of engineered fill prevents sinking support posts when soils below are weak, maximizing effectiveness.
The “Bulb Of Influence”
No matter how strong your floor joist supports are, they can only bear as much weight as the soils underneath them. Put simply, if the supports are sinking, your floor is going to sink with them.
To address this, our contractors take advantage of something called the “bulb of influence”.
Before we install your support posts, we excavate a 2′ cube hole, filling it in with compressed, crushed stone. Then we place a concrete base on top of the center of this cube and position the jack post above that.
This cube of compressed, crushed stone disperses the weight pressing down into the soil outwards, dispersing it to approximately 10% of the pressure present at the bearing surface.
This means that even if the soils under the jack posts aren’t strong enough to support great weights, your system will still be more than sufficient to support the structure above.
How Do Other Floor Joist Support Methods Measure Up?
There are many different methods of basement or crawl space repair that contractors are using today, and some are much better than others, but all of them work at least some of the time.
Of course, if these repair methods never worked, then they would not be used anymore. However, at Baker’s Waterproofing, our reputation and written warranty depends on using solutions that will be permanent — and will work all of the time.
