5 Signs Your Artificial Grass Was Installed Incorrectly

Persistent ripples, visible joins, lifting edges, standing water and movement underfoot may indicate an artificial grass installation needs closer inspection. These signs do not automatically prove poor workmanship, as several issues have more than one possible cause. 

Before making changes, inspect the affected area carefully and record what you find. Some problems improve with settling or maintenance, while others may point to issues beneath the surface. This guide explains what to look for and the most sensible next steps. 

Before You Decide the Installation Is Faulty

Check when the lawn was installed, whether the problem is changing and whether routine maintenance affects it before deciding there is an installation fault. A careful assessment helps distinguish cosmetic issues from problems that need further investigation.

Record the installation date, when the issue first appeared, whether it is worsening, recent weather conditions and whether the affected area has been brushed or subjected to heavy furniture. Also note whether the problem is localised or affects the whole lawn.

What May Be Normal at First

Rolled grass may need time to relax after installation, while flattened fibres usually improve with brushing. Product-specific settling guidance should always be followed. If ripples, movement or visible defects persist or become more noticeable, they are worth investigating.

What to Record Before Making Changes

Before lifting or repairing anything, take clear photographs, record short videos where helpful, note the weather and mark the affected area. Good records make it easier to monitor changes and support any future inspection.

1. The Surface Has Persistent Wrinkles, Ripples or Uneven Areas

Persistent ripples or uneven areas may indicate base movement, poor preparation or incorrect positioning during installation, although some marks are cosmetic.

You may notice wrinkles, raised sections, shallow dips or movement underfoot. Possible causes include base settlement, inadequate compaction, heavy objects or storage creases. Temporary roll marks, flattened fibres and changes in pile direction can also affect appearance.

Check whether the backing moves or only the fibres, whether the ground feels firm and whether the ripple returns after brushing or continues to spread.

Avoid cutting the grass, applying adhesive or weighing the area down before identifying the cause.

A storage crease may improve over time, while a raised section that shifts underfoot is more likely to need further investigation.

2. The Joins Between Sections Are Clearly Visible

A visible join may indicate incorrect cutting, poor alignment, base movement or a weak bond beneath the surface, although appearance alone does not confirm an installation fault.

You may notice a light or dark line, a gap, a ridge or sections moving apart. Possible causes include misaligned pile direction, incorrectly cut edges, adhesive failure or movement beneath the join. Recently installed fibres or changing light can also make a seam appear more noticeable.

Check for a physical gap, confirm the pile runs in the same direction and see whether the sections move independently.

Avoid adding adhesive, recutting the edges or forcing fibres into place before identifying the cause.

A visible seam differs from one that gradually opens underfoot.

3. The Edges Are Lifting or Curling Up

Lifting or curling edges may indicate weak perimeter fixing, base movement or damage around the lawn boundary, although localised lifting can have other causes.

You may notice raised corners, gaps beside paving or movement around borders. Possible causes include insufficient fixing, unsuitable edging, base settlement, repeated foot traffic or water beneath the edge. Furniture movement or accidental damage may also be responsible.

Check whether the edging is secure, the surrounding surface is level and the issue is localised.

Avoid gluing over damp surfaces or adding fixings before identifying the cause.

A single lifted corner differs from widespread edge movement across the lawn.

4. Water Collects on the Surface After Rain

Repeated pooling may indicate low spots, drainage issues beneath the installation or wider site conditions rather than a fault with the grass itself.

Check whether puddles always appear in the same place, how long they remain and whether the surrounding ground drains normally. Temporary surface water after exceptionally heavy rainfall differs from persistent pooling after ordinary showers.

Avoid piercing the backing or adding loose material before identifying the cause. Lasting drainage issues may require assessment of the base and surrounding site, not just the artificial grass.

5. The Grass Moves, Sinks or Feels Unstable Underfoot

Grass that shifts, sinks or feels unstable underfoot may indicate base movement, inadequate fixing or settlement beneath the surface rather than a problem with the fibres.

You may notice soft spots, dips, sliding sections or movement around joins and edges. Possible causes include poor compaction, base settlement, loose laying materials, water affecting the sub-base or weak perimeter restraint. A shockpad or recently completed installation may also create a softer feel.

Check whether only the fibres compress or whether the backing moves, whether the issue is localised and whether standing water or opening seams are also present.

Avoid adding extra fixings, hiding dips with infill or cutting into the grass before identifying the cause.

Natural fibre compression differs from the entire surface shifting or sinking, which is more likely to require further investigation.

How Serious Is the Problem?

The seriousness depends on whether the issue is cosmetic, localised or becoming worse. Use the symptoms to decide the most appropriate next step.

What to Do Before Contacting the Installer

Record the issue before requesting an inspection and avoid altering the affected area. Clear evidence helps identify the cause and supports a constructive discussion.

Before contacting the installer:

1. Take dated photographs and short videos.

2. Note when the issue appeared and whether it is worsening.

3. Record recent weather conditions.

4. Gather invoices, quotations and product details.

5. Review any installation or care guidance.

6. Mark the affected area and write a brief factual description.

Avoid making DIY repairs first, as they may make the original cause more difficult to assess.

Can a Poor Artificial Grass Installation Be Repaired?

Some installation problems can be repaired, while others involving the base or drainage may require more extensive work. The correct solution depends on the underlying cause rather than the visible symptom.

Local repairs may include re-securing an edge, improving a small join, re-levelling a limited area or replacing one damaged section. Widespread base movement, drainage issues or failed perimeter restraint may require larger remedial work.

Avoid choosing a repair before the installation has been assessed, as cosmetic fixes rarely resolve structural problems. Where replacement is necessary, matching an older lawn can be difficult due to wear, pile direction and product availability.

When Replacement May Be More Sensible

Replacement may be the better option if several faults affect the lawn or the base requires extensive work. Repairing isolated areas is not always the most cost-effective solution.

Consider replacement where there is widespread base movement, multiple failed joins, persistent drainage issues or no suitable match for the existing grass. Repair costs approaching the price of a new installation may also influence the decision.

A replacement lawn will not resolve problems caused by an unstable base, so the underlying issue should always be addressed first. If replacement is appropriate, explore the artificial grass range to compare suitable options.

Frequently Asked Questions About Poor Artificial Grass 

How Long Does Artificial Grass Take to Settle?

Settling varies between products. Follow the manufacturer's guidance and investigate any persistent changes.

Are Visible Joins Normal?

Slight visibility from certain angles can be normal. Gaps or movement should be checked.

Should Artificial Grass Move Underfoot?

Fibres compress naturally, but the backing should not noticeably slide or sink.

Why Is My Artificial Grass Uneven?

Possible causes include roll marks, pile direction, base settlement or movement beneath the surface.

Can Pooling Water Be Fixed Without Lifting the Grass?

It depends on the cause. Some drainage issues require further assessment beneath the surface.

Should I Contact the Installer or Supplier?

Contact the installer about fitting concerns and the supplier for product-specific guidance where needed.

Persistent ripples, visible joins, lifting edges, standing water and movement underfoot all deserve careful assessment. None of these symptoms automatically identifies the cause, which is why diagnosis should always come before repair.

Record the problem, monitor whether it changes and identify whether the issue relates to the surface, the fixing, the base or drainage before making alterations. If you remain unsure, review the relevant Tuda Grass guidance or contact us for practical advice before taking the next step.
