Worried About Sagging Floors?

Need a steel tube? Are you concerned about fixing a sagging or bouncy floor? Many issues can cause uneven floors:

  • Existing piers settling due to inadequate footing
  • Floors weakened by wood rot
  • Floor systems underdesigned for their current weight load
  • The length of the floor is greater than the capacity of your existing piers

It doesn’t matter if you’re installing a new bathtub, a granite countertop for the kitchen, or a massive fish tank for the living room, you need to offset the weight of your new installation. Furthermore, hidden wood rot can create uneven floors.

Sagging floors are never a good thing. They decrease the value of your home, damage your home’s structural integrity, and put you and your family in danger. With the PowerPost® Steel Tube, you can replace your older steel tube with a newer, fresher model!

We Offer the Best Support Posts On the Market

The PowerPost® steel tube is an extremely high strength, adjustable steel column designed to stabilize or raise sinking and uneven floors. Our galvanized steel tube is made with zinc-coated components to easily protect against corrosion. This protection ensures your steel tube lasts longer than the model you are replacing.

Furthermore, our product strengthens crawl space beams and assists in leveling the floor. Although uneven floors are a common issue, we are happy to offer a comprehensive solution!

We Also Offer The PowerPost® Kit

Need a comprehensive support solution? Pair the steel tube with our PowerPost® Kit. When you order the full kit, you’ll receive:

  • Fully adjustable
  • Galvanized steel tubes & zinc-coated components easily protect against corrosion
  • Easy installation even in tight conditions
  • Stronger and higher weight capacity than the jack-posts found in local stores
  • Can be properly fastened to the beam above and the concrete footing below
  • Made in the USA!
