Check the floor before you start

Solution A: Add a bridge
Nail the steel bridge between the tie rods.Solution B: add plywood
Nailed plywood (CDX or BC) under the floor reinforcement.Solution C: add a wall or a beam
Build walls or place beams under braces.

Years ago, while working as a carpenter, I helped harden the floor by driving new 2×10 nails into each of the 2×10 spacers that supported the floor. It was a complicated and expensive undertaking: working in the unfinished basement below ground, we had to remove the plumbing and electrical lines that ran through the struts, then reinstall them after the new 2×10 tubes were in place .

It worked. By doubling the joggers, we reduce their “deflection” (the distance they would bend under weight). The floor barely bounced and the customers were happy. But I know now that we can make this ground harder – even harder -with less hassle and cost.

This article will show you three best ways to recover the value of a trade. You can harden the floor in one room or in as many rooms as you want. The methods we will cover for creating the floorStronger, but not necessarilystronger. If your floors are rough and also sag significantly, they are probably too weak. You may need the help of a structural engineer to solve this problem, but start by calling your local building inspector, who will give you a free consultation.

You don’t need any special skills or tools to harden the floor, and all materials are available at home centers. The fixes we will show work for both solid wood and wood slats. But there’s a catch: For two of the three fixes we’re showing (Solutions A and B), you need to access deck links from below. This means having an unfinished basement, a basement with an easily removable drop ceiling, or an accessible crawl space. Otherwise, you’ll have to knock down the drywall or sheetrock. The third solution (Solution C) will work even when the ceiling is finished.

Joists, the main structural element of a floor, rarely span the full width of a home. Instead, a wall or beam usually supports them near the middle. And if you have a beam, you need to make sure it’s not too weak before you reinforce the beams.

Here’s a simple test: head to the outer wall opposite the beam. Stand on your tiptoes, then drop hard into your heels. You will hardly feel any rebound here. Next, stand halfway between the exterior wall and the beam. Toe drop will cause the biggest reaction here.

Finally, stand near the rafters. Any reaction you may induce here should be weak, similar to what you feel along the outer wall. If the result is what you feel in the middle of the floor, the beams below are either smaller in size or not fully supported by the columns. Solve this problem first by asking your local building inspector about the correct sizing of the beams.

Solution A: Add a bridge

Connect the bridge
Secure the metal bridge with 1-3/8-in. joist hanger nail. Each bridge segment requires four nails, two at each end.Easy to do; modest improvement
Bridging reduces “deflection” (how much bend in joints) by about 50%. Installation is easy and inexpensive ($1 per connector for two rows of bridging), but it is not as efficient as other solutions.

Bridges, or “X-hooks”, allow participants to share the weight. When a step falls on a jockey, some of the force is transferred to neighboring joggers. Even if your participant already has a row of walkways in the middle of the span, adding a row on either side of the existing walkway will stiffen the floor.

This solution doesn’t harden the floor like the others, but since it’s relatively simple and inexpensive, you might want to try it first. If you don’t get the desired results, you can always try another solution.

Start by testing the initial bridging. If any of them are loose, add nails or screws to secure them. Add a new row of bridges to two-thirds of the span. For example, if your joint spans 12 feet, place the deck 4 feet from the foundation wall. And 8 feet. If there is no bridge in the middle of the span, install a row there.

Metal bridges are available at home centers in lengths to fit between 16-inch or 24-inch spaced connecting rods.

Solution B: Add a layer of plywood

Screw the plywood to the spacers
1-1/2 in. drive. drywall screws through the plywood and into the tie rods. Screws should be no more than 4 inches apart.Moderate difficulty; moderate improvement
Adding plywood reduces deflection by approximately 80%. It hardens the floor without creating obstructions in the basement, but costs more ($8 to $12 per jockey) than the other methods and will not work if you have installed plumbing or power lines under the braces .

When a seam folds down, the bottom edge bends slightly to one side or the other. One layer 3/4 in. the plywood is attached to the underside of the spacers, which helps prevent lateral flexing and stiffening of the floor.

For this repair to work properly, the top edges of the tie rods must be attached to the subfloor above. A rattle in a floor usually means the subfloor has come loose from the tie rods. If your subfloor is plywood and has little to no creaking, you will get great results. If your home is over 30 years old, your subfloor is likely made up of individual planks. You can still get good results with a subfloor like this if the planks fit together perfectly. But if there are large gaps between the boards or the floor is very creaky, this solution will be less effective.

The rock-solid bond between the new plywood and the underside of the plywood is very important; you’ll be using a lot of screws and construction adhesive. Begin by sanding the underside of each panel with coarse sandpaper (60 to 80 grit). Two or three times with sandpaper is enough to leave a clean and rough surface for the adhesive.

Then glue and screw the plywood to the panels. The plywood runs parallel to the struts, not across. 8 feet. the long panels are centered on the span, leaving the ends of the tie rods exposed.

If you want to attach the drywall to the ceiling later, you will need to install 3/4″ strips. plywood or 1×4 on the underside of the exposed connectors. You can use CDX plywood or BC plywood, which has a smooth side. Make sure the construction adhesive you use is recommended for the subfloor.

Solution C: add a wall or a beam

Cut a hole in the wall for the beam
Cut a “pocket” in the foundation wall to support the end of the beam. Start with a circular saw, then do the rest with a cold chisel. It’s a dusty, slow job if the wall is solid concrete. This will be easier if the wall is a hollow concrete block, but you need to fill the block the beam will sit on with concrete (insert newspaper into the wall first to prevent wet concrete from flowing through the block). To avoid all that hassle, you can instead place a post next to the foundation wall – no footing is needed as the post will rest on the base of the wall.Add a footer to each post
Fill in the base of each post by cutting 20 x 20 first. Drill holes in concrete floors with a circular saw and masonry blade. Wear eye protection and a dust mask when cutting concrete. Next, dig a hole 8 inches deep and pour the concrete.Stronger; great improvement
A wall or beam reduces defection by 90-98%, depending on its location. This makes the ground very hard, but it creates obstacles in your basement. It costs $3 to $5 per participant.

The longer a person pulls without support, the more they will bend. By building a wall under the braces, you divide the span. The upper floor will be more difficult if you place the wall between the braces.

If you are building a wall to support participants, be sure to place the posts directly and firmly under each coupler. If the wall has a door, place a double 2×6 header above the rough door opening.

A beam will make your basement more open, but installing one means a lot of work. A beam made up of two 2×12 bars must be supported by adjustable metal posts or 4×4 wooden posts every 10 ft. And you will need to lay the groundwork for these pillars to stand.

If you have I-joists, be sure to add a 2×4 block between the wall or beam and the subfloor at each joist.

Why are my floors bouncy?

If the joists or columns are spaced too far apart, the joists will sag and bounce. Home remodeling projects, such as adding an addition, installing new appliances, granite countertops or large furniture pieces can add extra weight and stress to the floor joists– leading to bouncy floors.

What causes bouncy floors?

Bouncy floors may be caused by one or a combination of the following issues: Water Damage – Water leaks from faulty pipes or the roof can damage the subfloors. Since laminate floors are typically made of plywood that doesn’t stand up to water, they eventually become bouncy with continuous exposure to moisture.

What causes upstairs floors to sag?

Sagging can be the result of undersized joists, an undersized support beam, or support posts that have rotted at the bottom or settled into the ground. Other causes can be joists that were notched or drilled in the wrong place (see our Guide to Notching and Boring Joists) or are weakened by decay or insect damage.

What is sagging floor?

Floors can sag for many reasons. For instance, they may sag due to the natural settling of your property or building materials over time. However, a sagging floor may also signify damage from water leaks or pests, like termites. In other instances, your floors could sag due to plain old wear and tear.

How do you level a sagging floor?

Why does my floor feel spongy?

A spongy feel underfoot might indicate that the subfloor is not securely attached to the floor joists. This condition allows the floor to give slightly when you step.

Why is my laminate floor bouncy?

A wood or laminate floor can only bounce when there is a gap between the underside of the plank and the sub-floor. When weight is applied to the flooring, it moves downward because it is not supported, causing the bounce.

How do you strengthen a loft floor?

If the attic joists are not adequate, one way to strengthen the floor for live loads is to sister the old joists. Sistering is the process of adding a new joist next to each existing joist. In the case of 2 x 6 joists, you can pair them up with additional 2 x 6 joists by nailing them together, side by side.

How do you strengthen a subfloor?

Rough up the subfloor with 60- to 80- grit sandpaper. Apply construction adhesive between all the joints of the existing subfloor. This will help eliminate existing squeaks. Apply construction adhesive to the subfloor as you apply each piece of new plywood.

Are bouncy floors normal?

Bouncy floors are a common phenomenon in homes, according to This Old House’s general contractor Tom Silva. Also known as spongy floors, this problem occurs in new and old homes alike. “Even structurally sound, code-compliant new floors can deflect, or flex, more than feels comfortable,” per This Old House.
