How to Prepare and Install Rubber Chippings
Rubber chippings are commonly used for children's play areas, garden pathways, landscaping projects and outdoor recreational spaces. Preparing the ground correctly can help improve drainage, reduce maintenance and create a more even finish over time.
Proper ground preparation is often one of the main factors affecting how the surface performs long term, particularly in high-traffic areas such as playgrounds and garden walkways.

Step 1: Clearing and Levelling the Ground
Before laying rubber chippings, the area is typically cleared of grass, weeds, stones, roots and loose material. Removing organic growth and debris helps create a cleaner and more stable base for the surface layer above.
Levelling a Garden Area for Rubber Chippings
Once cleared, the ground is usually levelled to reduce uneven areas and minimise water pooling. Levelling a sloping garden or uneven ground before installation is worth doing carefully — even a modest slope can cause rubber chippings to migrate over time, particularly in heavy rainfall.
For smaller domestic areas, a garden levelling rake or lute is typically used to redistribute soil and create an even surface. For larger or more significantly sloped areas, a mini-digger or garden levelling service may be more practical. The goal is a flat, firm, compacted base that supports consistent depth across the full installation area.
Drainage should also be considered during ground preparation, particularly in gardens or play areas that regularly hold standing water during wet weather. Improving drainage at this stage is far easier than addressing it after the surface is laid.
Step 2: Installing a Weed Membrane
A semi-permeable weed membrane — also called weed control fabric or weed suppressant membrane — is commonly installed beneath rubber chippings to separate the surface layer from the soil underneath. This helps reduce weed growth from below while also limiting soil contamination within the rubber surface over time.
How to Lay a Weed Membrane Under Rubber Chippings
Knowing how to lay weed membrane correctly is one of the most important steps in the installation. A poorly fitted or unpegged membrane can bunch up under the rubber chippings or leave gaps at edges where weeds can push through.
- Cut the membrane to size — leave a generous overlap at edges, around 100–150mm, so seams can be overlapped rather than butted. Overlapping seams maintains continuous coverage across the full area.
- Lay on a dry day — membrane is easier to work with and lay flat when the ground is not wet.
- Overlap seams by at least 150mm — this prevents gaps where weeds can find daylight and push through between sheets.
- Use weed membrane pegs — also called membrane pins or fixing pegs — to secure the membrane to the ground at regular intervals, typically every 0.5–1 m along the edges and seams. Pegging the membrane prevents it lifting or moving during spreading and in windy conditions.
- Trim around edges and obstacles — cut neatly around posts, edging boards and borders, leaving the membrane tight to the boundary of the installation area.
For heavier-use environments such as playgrounds, walkways or equestrian areas, a stronger, higher-GSM membrane is commonly preferred due to increased foot traffic and movement. A membrane rated at 100gsm or above tends to hold up better under the weight and movement of rubber chippings in high-traffic areas.
Does Weed Membrane Let Water Through?
Yes — a semi-permeable or permeable weed membrane is specifically designed to let water drain through while blocking light to prevent weed germination. Does weed membrane let water through? Only if it is correctly specified as permeable — a waterproof membrane under rubber chippings would cause water to pool on the surface after rain. Always confirm the membrane is permeable before installation.
Step 3: Spreading the Rubber Chippings
Once the base preparation and weed membrane are complete, the rubber chippings can be distributed evenly across the area. Many installations begin by placing smaller piles around the surface before levelling the material with a rake or shovel.
After spreading, the depth can be checked using a measuring tape to help maintain a consistent finish throughout the area. Working in sections — spreading, levelling, checking depth, then moving on — tends to produce a more even result than spreading all the material at once.
Edging for Rubber Chippings
Edging is worth fitting before or during the spreading step, particularly around pathways and play spaces. Playground edging — such as rubber edging for playground surfaces, timber edging boards or pressure-treated boards — contains the rubber chippings and reduces migration outside the installation area over time. Rubber playground edging is a common choice because it is flexible, durable and compatible with the material.
Without edging, rubber chippings tend to spread onto adjacent surfaces (grass, pathways, patios) gradually, increasing the frequency of top-up required to maintain the correct depth.
For decorative landscaping projects, you can also compare different rubber mulch colours for gardens and play areas depending on the finish you are looking to achieve.
Typical Rubber Chipping Depths by Application
The depth used will usually depend on the intended application and the type of area being covered:
| Application | Common Depth Range |
|---|---|
| Decorative garden areas | 50mm – 75mm |
| Domestic play areas | 75mm – 100mm |
| Equestrian surfaces | 75mm – 100mm |
Deeper installations are often used in higher-impact environments where additional cushioning or surface stability may be preferred. For play areas near equipment with a fall height, your structural engineer or playground safety consultant will confirm the appropriate depth for your specific Critical Fall Height. See the rubber chippings vs bark guide for more on playground safety surfacing context.

Frequently Asked Questions
Do I need to level the ground before laying rubber chippings?
Yes. Levelling the ground before installation helps create an even surface depth across the full area, reduces water pooling and minimises the migration of rubber chippings over time. Even modest slopes can cause the surface layer to drift, particularly in high-rainfall areas or on steeper garden gradients.
What weed membrane should I use under rubber chippings?
A semi-permeable or permeable weed suppressant membrane is the correct choice under rubber chippings. It should let water drain through freely while blocking enough light to suppress weed growth. For play areas and high-traffic garden surfaces, a heavier-duty membrane (100gsm or above) is commonly preferred over lighter domestic grades.
Do I need weed membrane pegs?
Yes, particularly in larger areas, along seams, and at edges. Weed membrane pegs (also called membrane fixing pins) prevent the membrane from lifting or bunching during the rubber chipping spreading process and in windy conditions. Pegs are typically spaced every 0.5–1 m along seams and edges, and are widely available from garden centres and builders merchants.
How do I stop rubber chippings from spreading onto the lawn?
Playground edging or garden edging boards fitted around the perimeter of the installation area contain the rubber chippings and significantly reduce migration onto adjacent surfaces. Rubber playground edging is a popular choice because it is flexible, durable and sits flush with the surface level. Without edging, even well-laid rubber chippings will gradually migrate, requiring more frequent top-ups to maintain depth.
Can I lay rubber chippings on a sloping garden?
Yes, but the slope should be levelled or graded as much as practically possible before installation. On steeper slopes, rubber chippings are more likely to migrate downhill over time, particularly in areas of high foot traffic or heavy rainfall. Edging and a well-pegged membrane both help reduce movement on sloped ground.
How do I lay a weed membrane correctly under rubber chippings?
Clear and level the ground first, then roll out the membrane in overlapping strips (minimum 150mm overlap at seams). Secure with weed membrane pegs at regular intervals — particularly along seams and edges. Confirm the membrane is permeable so water drains through freely. Trim neatly to the edges of the installation area before spreading the rubber chippings on top.
How much ground preparation is needed before laying rubber chippings?
At minimum: remove vegetation, debris and loose material; level the ground to reduce uneven areas; lay and peg a permeable weed membrane. On compacted or clay-heavy ground, improving drainage (by forking or adding a layer of sharp sand) at the preparation stage will help the finished surface drain more effectively and last longer before top-up is required.
