In short
Artificial grass is secured differently depending on the surface: On gravel or crushed stone sub-bases in the garden using ground anchors or artificial grass nails at the edges and seams; on concrete or paving with artificial grass adhesive; and on balconies and roof terraces, it is usually laid loose and weighted down. Individual rolls are joined using seam tape and adhesive. A stable border created by edging prevents the artificial grass from shifting.
To ensure artificial grass remains permanently smooth, does not ripple, and does not come apart at the seams, it must be secured correctly. The appropriate method depends primarily on the sub-base and the intended use. Here is an overview of all common variants.
Which fixing method for which surface?
| Surface | Fixing Method | Note |
|---|---|---|
| Gravel/Crushed stone in the garden | Ground anchors or nails, edging | Standard for garden areas |
| Concrete, screed | Artificial grass adhesive at the edges and seams, or full-surface if necessary | Surface must be clean and stable |
| Paving, tiles | Adhesive at the edges or loose with weights | Ensure water drainage |
| Balcony, roof terrace | Lay loose, weight down edges | Never damage the waterproofing; consider wind uplift |
| Temporary areas | Laid loose, with double-sided adhesive tape | e.g., Event artificial grass |
Ground Anchors and Artificial Grass Nails
On a compacted sub-base of gravel and crushed stone, anchors are the standard fixing method. They are driven through the artificial grass into the sub-base.
- Place along the edges at regular intervals
- Provide additional security at seams if they are not glued
- Brush the blades aside before driving in to avoid trapping them
- Only drive anchors deep enough so the head is flush with the backing
- Never use anchors on waterproofing membranes or over utility lines
Gluing Artificial Grass
On solid surfaces like concrete, artificial grass is secured with special artificial grass adhesive. This is weatherproof and remains elastic even after curing.
- Clean the surface, let it dry, and remove any loose debris
- Lay out the artificial grass, cut to size, and fold back the edges
- Apply adhesive evenly to the surface
- Lay the artificial grass down and press firmly
- Observe the curing time according to the manufacturer’s instructions before using the area
Ensure that water can still drain away. Full-surface gluing on areas without a slope will otherwise lead to waterlogging.
Joining Seams
For larger areas, multiple rolls are installed. To ensure the transitions remain invisible, the following applies:
- Roll out all strips in the same installation direction
- Trim the selvedges or edge strips cleanly
- Place the edges flush against each other without gaps or overlaps
- Place seam tape centrally under the seam and apply adhesive
- Press both strips down, ensuring no blades are glued down
- Brush the seam against the grain after curing
Proper Edging
Clean edging made of stone, metal, or plastic profiles provides support for the artificial grass and prevents the sub-base from sliding sideways. The artificial grass is cut flush to the edging and secured or glued there.
Common Mistakes When Securing
| Mistake | Consequence |
|---|---|
| Too few anchors at the edge | Artificial grass shifts or ripples |
| Artificial grass not acclimated | Ripples after securing – see Acclimatization |
| Blades glued into the seam | Visible seam |
| Full-surface gluing without a slope | Waterlogging and moss |
| Anchors through a waterproofing membrane | Moisture damage to the building structure |

Frequently Asked Questions About Securing Artificial Grass
Do you have to secure artificial grass?
On larger garden areas, yes, to prevent it from shifting or rippling. On balconies and small areas, loose laying with weighted edges is often sufficient.
Can you glue artificial grass to concrete?
Yes. On clean, stable concrete, artificial grass is secured with special, weatherproof artificial grass adhesive, usually at the edges and seams. It is important that water can drain away via a slope.
How do you join two strips of artificial grass?
The edges are placed flush against each other, seam tape is placed centrally underneath and coated with artificial grass adhesive. Both strips are then pressed down, ensuring no blades are glued in.
How many ground anchors do you need for artificial grass?
This depends on the area, shape, and sub-base. The key is seamless securing along the edges at regular intervals and at non-glued seams. Manufacturer specifications provide guidance here.
