Artificial Grass Sub-Base Calculator
FAQs
How much subbase do I need for artificial grass? The amount of subbase needed for artificial grass can vary depending on factors such as the soil type, drainage requirements, and intended use. A rough estimate is around 50-100mm (2-4 inches) of compacted subbase.
What is a good sub-base for artificial grass? A good subbase for artificial grass typically consists of crushed stone, gravel, or a similar aggregate material. It should provide proper drainage and a stable, level surface for the artificial grass to sit on.
How much sand per m2 for artificial grass? You may need approximately 5-10kg of sand per square meter for infilling artificial grass, but this can vary depending on the specific type and height of the grass.
How do you prepare a sub-base for artificial grass? To prepare a subbase for artificial grass, you should:
- Remove existing vegetation and debris.
- Excavate the area to the desired depth (usually 50-100mm).
- Lay a geotextile membrane to prevent weed growth.
- Add and compact the subbase material.
- Ensure proper drainage by creating a slight slope if necessary.
- Finally, level and smooth the subbase.
How much sub-base per square metre? As mentioned earlier, you’ll typically need around 50-100mm of subbase material per square meter.
Should I put a membrane under the sub-base? Yes, it’s a good practice to put a geotextile membrane under the subbase to prevent weed growth and promote proper drainage.
Do you put sand under artificial grass? Yes, sand is often used to infill artificial grass to provide stability and help the fibers stand upright.
What happens if you don’t put sand under artificial grass? Without sand infill, the artificial grass may not have enough stability and can become uneven or wrinkle over time. It may also not look as natural.
Can I lay artificial grass without a sub-base? You can, but it’s not recommended for long-term durability and performance. A sub-base provides stability, proper drainage, and helps prevent the artificial grass from sinking or becoming uneven.
How much sub-base do I need? I mentioned earlier that you’ll typically need around 50-100mm of subbase material.
How do you work out m2 for artificial grass? To calculate the square meterage for artificial grass, measure the length and width of the area in meters and multiply the two measurements together.
Can I lay artificial grass on soil? You can, but it’s advisable to have a sub-base or at least a layer of compacted sand or aggregate to provide a stable and well-draining foundation.
Does the sub-base need to be level? Yes, the sub-base should be level and evenly compacted to ensure a smooth and even surface for the artificial grass.
What is the best surface to lay artificial grass on? The best surface is a properly prepared sub-base made of crushed stone or similar material. This provides stability, drainage, and durability.
What area will 1 ton of sub-base cover? One ton of sub-base material can cover approximately 10-15 square meters when applied at a depth of 50-100mm.
How thick should my sub-base be? A sub-base thickness of 50-100mm is generally recommended.
How much does a ton of sub-base cover? As mentioned earlier, one ton of sub-base can cover approximately 10-15 square meters at a depth of 50-100mm.
Is 50mm subbase enough? A 50mm sub-base can be sufficient for some applications, but a thicker sub-base, around 100mm, is more commonly recommended for better stability and drainage.
What is the minimum thickness of a sub-base? The minimum thickness of a sub-base for artificial grass is typically around 50mm, but thicker is generally better for stability and longevity.
Should you wet the sub-base before compacting? It’s not necessary to wet the sub-base before compacting unless you’re using materials like clay that benefit from moisture for compaction.
Why do you brush sand into artificial grass? Brushing sand into artificial grass helps to weigh down the fibers, provide stability, and keep the grass standing upright for a more natural appearance.
What should you not put on artificial grass? Avoid putting sharp objects, open flames, chemicals, or heavy machinery on artificial grass as these can damage or melt the fibers.
How do you secure artificial grass edges? Artificial grass edges can be secured with landscaping spikes or nails. Additionally, you can use adhesive or joiner strips to connect seams and edges.
Can you use limestone chippings as a sub-base? Yes, limestone chippings can be used as a sub-base material for artificial grass. Ensure proper compaction for stability.
What is the cheapest sub-base for artificial grass? The cheapest sub-base option may be crushed stone or gravel, but it’s essential to balance cost savings with the need for proper drainage and stability.
How do you compact ground for artificial grass? You can compact the ground using a mechanical compactor or a hand tamper to ensure it’s firm and level.
Can I just lay artificial grass on top of grass? While it’s possible, it’s not recommended as it can lead to an uneven surface and drainage issues. Proper preparation with a sub-base is preferable.
How do I know how much base I need? Calculate the area’s square meterage and then determine the desired sub-base thickness (e.g., 50-100mm). Multiply the area by the thickness to find the volume of sub-base needed.
How deep is a subbase course? A subbase course is typically 50-100mm deep, but the depth may vary depending on specific project requirements.
What makes a good sub-base? A good sub-base should provide stability, proper drainage, and a level surface. Materials like crushed stone or gravel are commonly used.
How thick should artificial grass be? Artificial grass comes in various thicknesses, but common options are between 20mm and 40mm, depending on the intended use and aesthetics.
How many meters is a roll of artificial grass? A roll of artificial grass can vary in length, but a standard roll is often 2 or 4 meters wide. The length can vary, but it’s typically sold in rolls of 25 meters or more.
How much fall on artificial turf? Artificial turf should have a slight slope of 1-2% to facilitate proper drainage.
Can I lay artificial grass directly on gravel? It’s not recommended to lay artificial grass directly on gravel. A sub-base of crushed stone or similar material is typically necessary for stability and drainage.
Can I use old bricks as a sub-base? Old bricks can be used as a sub-base material if they are broken down and compacted properly to create a stable surface.
Can I use gravel as a sub-base? Yes, gravel can be used as a sub-base material for artificial grass, but proper compaction is essential for stability.
How do you compact a sub-base without a compactor? You can compact a sub-base without a mechanical compactor by using a hand tamper or a heavy roller.
How do you hold artificial grass in place? Artificial grass is typically held in place with landscaping spikes or nails around the edges. You can also use adhesive or joiner strips for seams and edges.
What sand goes under artificial grass? Typically, a sharp, washed sand (sometimes referred to as silica sand) is used for infilling artificial grass.
How many square meters does 1 tonne cover? One tonne of material can cover approximately 10-15 square meters when applied at a depth of 50-100mm.
What is MOT Type 1 sub-base? MOT Type 1 is a standardized sub-base material in the UK, consisting of crushed stone or gravel. It’s commonly used in construction and landscaping projects.
How thick is a sub-base layer? A sub-base layer is typically 50-100mm thick, but the thickness may vary based on project requirements.
What is the difference between Type 1 and Type 2 sub-base? MOT Type 1 sub-base is typically made of crushed stone or gravel and is suitable for heavier applications. Type 2 is a less rigid material, often used for lighter-duty applications.
What can I use as a sub-base? You can use various materials as a sub-base, including crushed stone, gravel, compacted sand, or aggregate, depending on your project’s requirements.
Can I use broken concrete as a sub-base? Broken concrete, also known as rubble or recycled concrete, can be used as a sub-base material if it’s properly compacted to create a stable surface.
