Artificial Grass Sub Base Calculator
FAQs
How much sub-base do I need for artificial grass?
The amount of sub-base needed for artificial grass depends on various factors such as the type of soil, drainage requirements, and intended use of the area. As a general estimation, you would typically require around 50mm to 100mm of sub-base depth.
What is the cheapest sub-base for artificial grass?
The cheapest sub-base option for artificial grass is typically crushed rock or aggregate. It provides adequate drainage and stability at a relatively low cost.
What is a good sub-base for artificial grass?
A good sub-base for artificial grass should provide proper drainage, stability, and support for the turf. Common options include crushed rock, aggregate, or a combination of materials like crushed concrete and gravel.
Can I lay artificial grass without sub-base?
While it’s possible to lay artificial grass without a sub-base, it’s not recommended for long-term durability and performance. A sub-base helps with drainage, prevents unevenness, and enhances the lifespan of the artificial grass.
How much sharp sand do you put under artificial grass?
Typically, you’d use around 20-30mm of sharp sand as a bedding layer beneath the artificial grass to provide a smooth surface and aid in drainage.
How much sub-base per square metre?
For a sub-base depth of around 50mm to 100mm, you would need approximately 0.05 to 0.1 cubic meters (or 50 to 100 liters) of sub-base material per square meter.
Can I use gravel as a sub-base for artificial grass?
Yes, gravel can be used as a sub-base for artificial grass. It provides good drainage and stability when properly compacted.
Can I use sharp sand as a sub-base for artificial grass?
Sharp sand is typically used as a bedding layer rather than a sub-base. It can be used in combination with other materials for the sub-base or as a top layer for leveling.
Can I use sand as a sub-base for artificial grass?
Sand alone is not ideal as a sub-base for artificial grass because it lacks the necessary stability and drainage capabilities. However, it can be used in combination with other materials in the sub-base construction process.
Do you put sand or gravel under artificial grass?
Both sand and gravel can be used in the artificial grass installation process. Gravel is typically used as a sub-base, while sand is often used as a bedding layer to provide a smooth surface for the turf.
How do you compact a sub-base for artificial grass?
A sub-base for artificial grass should be compacted using a vibrating plate compactor or roller to ensure proper stability and uniformity.
Can I lay artificial grass on pea gravel?
While it’s possible to lay artificial grass on pea gravel, it’s not recommended as pea gravel may not provide adequate stability and may result in an uneven surface over time.
Can I just lay artificial grass on soil?
It’s not recommended to lay artificial grass directly on soil as it can lead to poor drainage, unevenness, and potential degradation of the turf over time.
Why do you need sand under artificial grass?
Sand is often used as a bedding layer under artificial grass to provide a smooth surface, improve drainage, and help hold the turf in place.
What is the best surface to lay artificial grass on?
The best surface to lay artificial grass on is a well-prepared sub-base consisting of compacted aggregate or crushed rock, topped with a layer of sharp sand for smoothness.
Do you sprinkle sand on artificial grass?
Yes, sand can be sprinkled on artificial grass to help weigh it down, prevent movement, and enhance its natural appearance.
Can I use sand as a sub-base?
Sand alone is not suitable as a sub-base for artificial grass as it lacks stability and drainage properties. It’s best used as a bedding layer or infill material.
How do I figure out how much sub-base I need?
To calculate the amount of sub-base needed, multiply the area’s length by its width and then by the desired depth (in meters). This will give you the volume of sub-base required in cubic meters.
What area does 1 tonne of sub-base cover?
One tonne of sub-base material typically covers approximately 10 square meters at a depth of 100mm.
How thick should my sub-base be?
A sub-base for artificial grass should ideally be around 50mm to 100mm thick, depending on factors such as soil type, drainage requirements, and intended use.
What should you not put on artificial grass?
Avoid putting heavy objects or sharp items on artificial grass as they can damage the turf fibers. Additionally, avoid using chemicals or solvents that may degrade the synthetic material.
Can you lay artificial grass on slate chippings?
Slate chippings may not provide adequate stability and may result in an uneven surface for artificial grass. It’s generally recommended to use a proper sub-base material like crushed rock or aggregate.
Should I put membrane under sub-base?
A geotextile membrane can be used under the sub-base to prevent weed growth and aid in drainage. It’s not always necessary but can be beneficial in certain situations.
What to do before laying artificial grass?
Before laying artificial grass, prepare the area by removing any existing vegetation, leveling the ground, and installing a suitable sub-base. Ensure proper drainage and address any underlying issues.
What is the fine sand for artificial grass?
The fine sand used for artificial grass is typically silica sand, which is clean, round, and does not contain any organic material. It’s used as an infill to support the turf fibers and provide stability.
