A shed base is the most important aspect of constructing a sturdy and durable shed. Amongst a few alternatives available, a plastic shed base is now preferred due to its durability, lightweight, and extremely easy to install. To the amateur, installing a plastic shed base may appear to be a somewhat daunting task. However, with the right advice, the process will turn out pretty simple and highly rewarding.
In this tutorial, we show you some valuable tips, a step-by-step guide, and some practical advice that will help you set up the plastic base perfectly and give your shed stable support.
Why Choose a Plastic Shed Base?
Before going into the installation tips, let’s understand why a plastic shed base is a very good decision. Firstly, plastic bases are lightweight and easy to handle compared to concrete or timber foundations. Secondly, they are very resistant to moisture, rot, and insects, which is what makes them durable.
Besides that, plastic shed bases provide considerable drainage to avoid the gathering of water under your shed. This, therefore, decreases the huge building damage over a great deal of time. Ultimately, using a plastic shed base offers you convenience, durability, and peace of mind.
Materials And Tools Required
Before starting anything, gather all the required materials and tools. It will make the entire installation process smooth and the work will go on without any irrelevant delay. For the installation of a plastic shed base, you generally need:
Pre-assembled or individual plastic grid panels for a shed base.
- A spirit level
- Shovel and rake
- Tape measure
- Gravel or sand for levelling
- rubber mallet or hammer
- String line or marking paint
In that way, everything will already be prepared and installation could go well.
Step 1: Site Selection And Preparation
First of all, choose the place where your shed is going to sit. It should be level and a trifle higher than the general surroundings so that water should not collect there. Having chosen the site, it must be prepared by removing the grass, roots, and other debris.
Then, make the area level with the use of a rake or shovel. You can add an extra layer of 2-3 inches with compacted gravel or sand for extra stability. Not only will it help you level the ground but also the drainage under your plastic shed base. Use a spirit level to ensure the surface is even. An uneven base may cause the shed to shift or the doors may misalign over time.
Step 2: Assemble The Plastic Shed Base
Most plastic shed bases come in modular panels, which are pretty simple to assemble. Lay out the panels according to the size of your shed by following the manufacturer’s instructions for proper alignments.
Use a rubber mallet to secure the panels together tightly. The interlocking design offers stability, and the panels can often be cut if necessary to accommodate unique dimensions. Go slow with this step because the better the base is put together, the better the foundation will be for years to come.
Step 3: Level And Secure The Base
After the panels are put together, recheck for levelness. Slight deviations can cause installation problems in placing the shed. So, move gravel or sand underneath any low spots and recheck with a spirit level.
Once this base is level, ensure that all panels are securely fixed to one another. Depending on the design, some plastic shed bases may provide additional fixing pins or stakes for insertion into the ground to prevent any form of lateral movement in wind conditions. This, therefore, makes sure that a shed base is stable under the weight and weather conditions.
Step 4: Attaching The Shed To The Base
With the plastic base laid, you can set your shed on top. Remember, if possible, have someone to help you lift and set the shed to avoid the possibility of damaging the base or the actual structure. Carefully set the shed and align its edges with those of the base.
If the shed is large, you may want to temporarily support it with blocks to permit final adjustments. Secure the shed in place, taking into consideration any of the manufacturer’s instructions. With the plastic shed base, your structure should be even and remain stable over time.
Step 5: Final Checks And Maintenance
After installation, check carefully: Make sure that the shed sits level, that doors open and close without issues, and that the seams between the shed and the base have no gaps. Periodically inspect the plastic shed base for signs of movement, wear, or accumulation of water from heavy rain.
Maintenance, when compared to timber or concrete bases, is at a minimum, but clearing the area of debris and checking the drainage will ensure years of performance. With the right care, your shed and its plastic base will go on serving you for several years.
Extra Tips for Beginners
- Plan Ahead: Before purchasing a plastic shed foundation, take proper measurements of the shed and the site.
- Work with a Partner: It makes lifting and aligning panels much easier and safer.
- Use Gravel or Sand: This will help with leveling, drainage, and avoidance of potential water damage.
- Manufacturer Instructions: Plastic shed bases differ in the ways in which they need to be put together.
- Consider the weather: Install during dry weather to avoid muddy conditions complicating leveling.
Conclusion
Installing a plastic shed base can easily be straightforward, even for novice workers. Preparing your site, assembling and leveling the base with care, and following the instructions of the manufacturer will provide you with a solid, level base for your shed. Besides being easier to install than its more traditional counterparts, it also brings in durability, low maintenance, and excellent drainage.
Spending time installing the right shed base ultimately pays dividends by keeping your shed safer, functional, and durable.
