How To Reinforce Plastic Shed: Make Your Shed More Durable

A plastic shed is a fantastic investment for any homeowner in the gardening community. They provide low-maintenance storage solutions and are both inexpensive and durable. However, they can also be easily damaged if proper reinforcement isn’t done.

Fortunately, there are several ways to strengthen your shed and make it safer and more secure. However, before undertaking any project on your own, you’ll need access to a few basic tools and materials, as well as an understanding of all aspects of home improvement.

In this post, we’ll examine three methods on how to reinforce plastic sheds. When completed, they’ll prevent your shed from collapsing under its own weight or damage from extreme weather conditions.

How To Reinforce Plastic Shed

While there are several different ways on how to reinforce plastic sheds there is one thing they all have in common: they all help you securely lock your shed in place.

Let’s take a look at these common methods…

Method 1 – Install Concrete Footings with Rebar Anchors

Many plastic sheds don’t have a cement floor, so you might need to install a new one. This will reinforce your shed and prevent it from sinking or tipping over in bad weather.

So, let’s have a look at how to reinforce a shed wall using concrete footings so that it can last a long time.

Tools Needed

  • A level
  • A shove
  • A Mallet

Installation Process

Step 1 – The first thing to anchor a plastic shed to a concrete slab is to dig out dirt from around your shed (about 4-inch deep) until you reach solid ground.

Step 2 – Then, cut the rebar (reinforcing bar) into pieces about four feet long. Hammer them into place with a mallet and bolt them together on each side of your shed’s foundation.

Step 3 – Once they’re connected, pour in concrete until they are submerged. Let everything cure for at least one day before moving on to the next step.

NOTE: Make sure to mix concrete according to package instructions. Remember to leave a little space at the top because concrete expands as it dries.

Final step – Cover with gravel for stability and safety.

Method 2 – Use Metal Brackets

Metal brackets are often used in conjunction with wood to ensure your shed is stable and secure. And unlike wood, they are not susceptible to rot or decay, ensuring your shed will last a long time and withstand hurricanes.

Tools Needed:

  • Screwdriver
  • Drill
  • Marker n/ Chalk line
  • Level

Installation Process

Step 1 – To install metal brackets around your shed, locate any potential weak points in your plastic. These might be on the roof or corners.

Step 2 – Then mark out where each bracket should go, as well as how high up on the walls you want them.

Step 3 – Using a drill, make small holes through each weakness. Next, run some screws up through your hole and into each bracket hole.

Step 4 – Finally, attach as many brackets as you need to each to reinforce shed walls to provide additional protection from extreme weather. That way, if one side blows off, the other remains intact.

Method 3 – Lay Mesh Wire at All Four Corners of Your Shed Foundation

If you choose a plastic shed makeover, another option is to install four steel mesh grids around each corner of your shed foundation. These will act as reinforcement bars that won’t need maintenance.

So, here is how to anchor a shed to ground using a lay mesh wire.

Tools Needed

  • Wire clippers/cutters
  • Hammer

Installation Process

Step 1 – First, dig 3-inch holes spaced evenly apart in each corner.

Step 2 – Afterward, place your steel mesh grid into the hole so it sticks up above ground level by an inch or two.

Step 3 – Having laid out all four corners and placed them firmly on the base of your fence posts, cut off any excess wire hanging over. This can be done with wire clippers or cutters.

Step 4 – The next step is how to seal a plastic shed. Using a thread seal tape or clear silicone, glue all four ends of your wires to the post base for proper sealing and stability.

Step 5 – Finally, fill any gaps between the cracks with a concrete sealant. Ensure you have enough adhesive so that water doesn’t slip through and soak into cracks, causing damage later.
