Product Information
Full details
The ProBase Garden Shed Base Kit in Black is designed for homeowners needing a stable, long-lasting foundation for garden buildings like sheds, workshops, and summerhouses. Its key benefit is providing a robust, easily installed base that prevents ground movement and weed growth. A potential consideration is the need for infill (like gravel) for maximum load-bearing capacity in extreme conditions. This kit features super strong, interlocking grids made from 100% recycled plastic, a heavy-duty weed-resistant membrane, and load-spreading feet, eliminating the need for gravel in many applications.

FAQs
What is the main benefit of using ProBase?
ProBase provides a stable, level, and durable foundation for garden buildings, preventing ground movement and offering integrated weed control.
Do I need to use gravel with the ProBase system?
The system's load-spreading feet mean gravel is often not required for standard garden sheds. However, adding gravel is recommended for maximum load-bearing capacity with heavier structures like workshops or log cabins.
How many grids are typically needed for a shed base?
The number of grids depends on the size of your garden building. Each grid is 500mm x 500mm. For example, a 5ft x 7ft shed would require approximately 35 grids (5ft = 1500mm = 3 grids wide, 7ft = 2100mm = 4.2 grids long, so 3 x 4.2 = 12.6 grids per layer, usually laid in two layers for stability, totalling approx. 25-30 grids. For a 7ft x 10ft shed, you'd need approximately 70 grids.
Can ProBase be used on uneven ground?
While ProBase works best on a prepared, level surface, minor unevenness can often be compensated for during installation. Significant slopes should be addressed before laying the grids.
Is the ProBase system environmentally friendly?
Yes, the grids are made from 100% recycled plastic, making it an environmentally conscious choice for your garden building foundation.
What is the load-bearing capacity of a single grid?
Independently tested, each grid can support over 50 tonnes of vertical load when empty of gravel, and over 175 tonnes when filled with gravel.
How is the weed membrane supplied?
The weed-resistant membrane is supplied cut to the size of the kit, ensuring complete coverage of the base area.
Troubleshooting
Grids not interlocking easily
Ensure the connection points are clean and free of debris. Check that the grids are aligned correctly before applying pressure.
Uneven surface after installation
The ground beneath the grids may not have been sufficiently levelled before assembly. Adjust the ground or reposition grids if necessary.
Weed growth through the base
Verify that the weed membrane was fully laid out and that there are no gaps. Ensure the gravel infill (if used) adequately covers the membrane.
Base feels unstable under load
Consider adding gravel infill to the grids for increased load distribution, especially for very heavy structures or on softer ground.
Pros and Cons
Pros
- Provides a stable and level base, preventing ground sinking or movement.
- Made from durable, 100% recycled plastic for a sustainable choice.
- Includes weed membrane, simplifying site preparation and maintenance.
- Easy and quick to assemble, requiring no special skills or tools.
- Versatile, suitable for a wide range of garden structures.
- Load-spreading feet reduce or eliminate the need for a gravel infill.
Cons
- May require gravel infill for extremely heavy loads or specific ground conditions.
- The initial cost might be higher than traditional methods like paving slabs.
- Requires a relatively level surface for initial grid placement.
Setup, Compatibility & Care Instructions
Setup:
- Prepare the Area: Clear the intended site of vegetation and large stones. Ensure the ground is reasonably level.
- Lay the Membrane: Unroll and position the provided weed-resistant membrane across the entire base area.
- Assemble the Grids: Start at one corner and interlock the ProBase grids by pushing them together until they click securely.
- Expand the Base: Continue adding and interlocking grids until the desired base size is achieved.
- Optional Infill: For maximum load capacity, fill the grids with gravel, compacting it lightly.
- Position the Structure: Place your garden building directly onto the assembled ProBase grid system.
Compatibility:
- Garden Buildings: Suitable for timber sheds, plastic sheds, metal sheds, workshops, summerhouses, log cabins, and other garden structures.
- Ground Types: Works on most types of ground, including soil, grass, and existing patio areas.
Care:
- Cleaning: Wipe down the grids with a damp cloth as needed. Avoid abrasive cleaners.
- Maintenance: The system is largely maintenance-free. Ensure the weed membrane remains covered to prevent UV degradation.
