Artificial grass no longer lying flat

Wrinkles, Ripples and Bubbles in Artificial Grass

Artificial grass should sit dead flat. Ripples mean the sheet has moved relative to the base, expanded in heat without room to relax, or that the base beneath it has softened.

The good news is that the grass itself is usually fine — it is the fixing and the base that need attention.

Artificial Grass work by Gardenscape in Essex

Heat expansion

Synthetic turf expands in strong sun. Installed tight in cool weather with no allowance, it can push into waves during a heatwave and often relaxes back as temperatures drop.

Correct acclimatisation before fixing — letting the roll relax in the sun — prevents most of this.

Base and fixing failures

A base of loose sand or unconsolidated stone shifts under foot traffic and the grass follows. Missing perimeter fixings let the sheet creep, most visibly at gates and doorways where traffic concentrates.

Ripples that reappear in the same place after being pulled out point to the base, not the grass.

How it's repaired

We release the perimeter, re-stretch the sheet, correct or recompact the base where needed, then refix with the appropriate edging and re-brush the infill.

Where seams have opened at the same time, they are re-jointed with adhesive and tape.

Frequently asked questions

Will ripples flatten out on their own?

Heat-related ripples often relax; movement-related ones will not.

Can existing grass be re-stretched?

Usually yes, if it is in good condition and long enough at the perimeter to refix.

What edging do you use?

Treated timber batten or steel edging, fixed so the perimeter cannot creep.

Lumps and ripples in your lawn?

We repair and re-lay poorly installed artificial grass.
