Say goodbye to the difficulty or chaos of placing slabs or concrete with our 18’x11′ ProBASE plastic shed base kit for setting up a foundation for your new shed. The installation process is swift due to its interlocking structure, allowing for effortless assembly. Despite being lightweight, it offers a sturdy and enduring base for your shed.

Crafted from 100% recycled plastic, this shed base is environmentally friendly. Furthermore, you can repurpose the base should you opt to relocate your shed. The base facilitates airflow and drainage beneath the shed, aiding in keeping the shed floor dry.

Setting up the base is a breeze – simply interlock the square grids and place them on a solid, flat surface. We suggest using 15kg of 10m pea gravel per square (gravel not included).

Each square measures 500 x 500 x 40mm. The package includes 84 squares and heavy-duty, commercially-graded weed membrane.

Features:
– Robust interlocking grid system shed base
– Effortless to lay and assemble
– Environmentally conscious premium recycled plastic
– Enhanced ventilation design
– Supplemental heavy-duty membrane
– Thorough instructions and professional customer assistance
– 2-year warranty

FAQs

The size of the shed depends on what you plan to store or use it for. Measure the items you plan to store and consider any additional space for moving around or future storage needs. Common sizes range from small (6×8 feet) for basic storage to large (12×24 feet) for workshops or extensive storage.
Sheds are typically made from wood, metal, or plastic. Wood is aesthetically pleasing and customizable but requires more maintenance. Metal sheds are durable and secure but can be prone to rust. Plastic sheds are low-maintenance and easy to assemble but may not be as sturdy as wood or metal.

Permit requirements vary by location. Check with your local building department or zoning office. Typically, small sheds (under 120 square feet) may not require a permit, but larger ones or those with electrical installations often do.

A solid foundation is crucial for stability and longevity. Options include concrete slabs, gravel bases, or wooden platforms. Choose a foundation based on your shed’s size, material, and the ground conditions of your site.
Look for sheds with features like weather-resistant materials, proper sealing, and robust construction. Ensure the shed has a good roof overhang, proper drainage, and secure locking mechanisms to protect against theft and weather damage.
Assembly time depends on the size and complexity of the shed. Small, simple sheds can be assembled in a few hours, while larger or more complex sheds may take a full day or more. Professional installation is also an option for those who prefer not to DIY.
Maintenance depends on the material. Wooden sheds need periodic painting or staining and checking for rot or pests. Metal sheds may need rust prevention treatments. Plastic sheds require minimal maintenance, typically just cleaning as needed.
Moving a shed is possible but can be challenging, especially for larger structures. It’s easier to move a smaller shed if it has a solid base. Consider the logistics and potential costs of moving before installation. If moving is likely, a portable shed might be a better option.
Many sheds come with detailed assembly instructions, making them suitable for DIY installation, especially smaller models. However, larger or more complex sheds may require professional installation to ensure they are properly and safely assembled. Assess your skill level, available tools, and the complexity of the shed before deciding.
