Does non-infill artificial turf need to be pre-laid before installation? In most professional installations, pre-laying—also called relaxation, conditioning, or unrolling—is a recommended preparation step. It allows the turf roll to relax after transportation and storage, helps the backing and synthetic fibers adapt to the installation environment, and can reduce the likelihood of wrinkles, ripples, and joint tension after installation.
However, pre-laying should not be treated as a substitute for proper sub-base preparation or professional installation. The recommended relaxation time and installation conditions can vary depending on turf construction, backing system, transportation conditions, ambient temperature, humidity, and the manufacturer's installation instructions.
For premium non-infill artificial turf systems, the combination of material stability, pre-laying, correct tension management, accurate cutting, and professional seam installation is generally more important than any single installation parameter.
Why Does Non-Infill Artificial Turf Need to Be Pre-Laid?
Non-infill artificial turf differs from conventional infill systems because it is designed to provide performance without relying on sand or rubber granules as loose ballast. This makes the dimensional stability of the turf system and the quality of installation particularly important.
Pre-laying mainly serves three purposes.
1. Pre-Laying Helps Release Transportation Stress
Artificial turf is normally manufactured and transported in rolls. During rolling, handling, loading, and transportation, the backing and synthetic fibers remain curved for an extended period.
When a turf roll is immediately cut and seamed after being unrolled, some residual curvature or internal stress may still be present.
After installation, this stress can gradually be released and may contribute to:
- Minor ripples
- Localized wrinkles
- Edge lifting
- Uneven seams
- Surface undulations
Allowing the turf to relax before final cutting and bonding gives the material time to recover naturally.
This is particularly relevant for long turf rolls and projects where the material has experienced extended transportation or storage.
2. Pre-Laying Allows the Turf to Adapt to Ambient Temperature
Most artificial turf fibers and backing materials are polymer-based, commonly incorporating PE, PP, or related polymer systems.
Like other polymer products, artificial turf can experience dimensional changes as temperature changes.
For example, turf transported in a relatively cool environment may expand after being exposed to warmer installation conditions. If the material is immediately cut and permanently fixed before reaching a more stable condition, additional stress may develop around seams and perimeter areas.
Pre-laying allows installers to assess the turf after it has adjusted to the actual site conditions.
This makes the final cutting dimensions more representative of the turf's installation state.
3. Pre-Laying Helps Synthetic Fibers Recover Their Appearance
Transportation can temporarily flatten or bend synthetic fibers.
After the turf is unrolled and left in a relaxed position, the fibers can gradually recover their intended orientation.
For non-infill systems using straight and curled fibers to create self-supporting performance, this recovery can be particularly useful.
The basic process is therefore:
Unroll → Relax → Inspect → Align → Cut → Seam → Secure
Rather than:
Unroll → Immediately Cut → Immediately Glue
How Long Should Non-Infill Artificial Turf Be Pre-Laid?
There is no single relaxation period that applies to every artificial turf product.
A practical reference for many projects is shown below:
| Ambient Conditions | Typical Relaxation Approach | Key Consideration |
|---|---|---|
| Above 30°C / 86°F | Several hours to approximately 24 hours | Avoid unnecessary prolonged direct solar exposure |
| 15–30°C / 59–86°F | Around 24 hours | Common installation range |
| 5–15°C / 41–59°F | Approximately 24–48 hours | Allow additional recovery time |
| Below 5°C / 41°F | Installation should be carefully evaluated | Follow product-specific requirements |
These figures should be regarded as practical installation guidance rather than universal certification requirements.
For turf that has experienced long-distance transportation, extended storage, or significant temperature changes, a longer relaxation period may be appropriate.
Instead of focusing only on the number of hours, installers should evaluate whether:
- Major wrinkles have relaxed;
- The backing lies relatively flat;
- The turf dimensions are stable;
- Fiber orientation has recovered;
- The material is suitable for final cutting and seaming.
The manufacturer's technical installation instructions should take precedence where they specify different requirements.
How to Pre-Lay Non-Infill Artificial Turf Correctly
Step 1: Inspect the Sub-Base Before Unrolling
Pre-laying should begin only after the installation area has been properly prepared.
The sub-base should be checked for:
- Surface flatness
- Compaction
- Drainage
- Standing water
- Loose aggregate
- Sharp objects
- Localized depressions or high spots
For sports applications, the finished base should normally be designed and verified according to the requirements of the relevant sports facility and synthetic turf system.
A practical tolerance sometimes used for artificial turf installation is approximately ≤5 mm over a 3 m straightedge, although project specifications may require tighter tolerances.
The key principle is simple:
Pre-laying cannot correct a defective sub-base.
If the foundation contains significant depressions or high spots, these defects may remain visible after the turf is installed.
Step 2: Unroll the Turf in the Correct Direction
The turf should be unrolled according to the planned fiber direction.
All rolls within the same visible playing or landscape area should be aligned consistently.
This is particularly important because synthetic fibers can reflect light differently depending on their orientation.
Incorrect alignment may produce a visible difference between adjacent rolls, sometimes described as a shading or “directional” effect.
Before cutting, installers should therefore confirm:
- Fiber direction
- Roll sequence
- Seam location
- Field markings
- Color and batch consistency
Step 3: Allow the Turf to Relax Naturally
Once unrolled, the turf should be allowed to relax without excessive stretching.
Installers should avoid attempting to force the material completely flat by aggressively pulling it.
Excessive tension can create unnecessary stress within the backing and seams.
A better approach is:
Unroll → Allow natural relaxation → Inspect → Make controlled adjustments
rather than aggressively stretching the entire roll.
Step 4: Perform Final Cutting After Relaxation
Final cutting is preferably performed after the turf has had adequate time to relax.
This helps reduce the possibility of:
- Oversized or undersized seams;
- Excessive seam tension;
- Insufficient perimeter material;
- Uneven roll alignment;
- Repeated cutting and adjustment.
For perimeter areas, installers should normally maintain sufficient material allowance for final trimming.
The exact allowance should follow the turf manufacturer's installation specification rather than applying a single universal dimension to every product.
What Installation Conditions Are Recommended?
The installation environment can significantly influence the behavior of artificial turf and adhesive systems.
For many synthetic turf projects, installers aim for moderate ambient conditions, often around:
15–30°C / 59–86°F
However, the acceptable range depends on the backing system, adhesive, sub-base and manufacturer's technical requirements.
Other important considerations include:
Surface Condition
The sub-base should be clean, stable and free from standing water.
Humidity
Relative humidity should remain within the adhesive manufacturer's recommended range.
Wind
Strong winds can make large turf rolls difficult to control and can affect seam alignment and adhesive application.
Rain
Seaming and adhesive bonding should generally be avoided when the backing or sub-base is wet unless the adhesive system has specifically been designed and approved for such conditions.
Common Mistakes When Pre-Laying Non-Infill Artificial Turf
Mistake 1: Skipping the Relaxation Process
Trying to save several hours during installation may increase the risk of having to correct wrinkles or seam alignment later.
For large sports fields, correcting an improperly installed seam can be considerably more complicated than allowing sufficient relaxation time beforehand.
Mistake 2: Treating Direct Sunlight as a Fast Relaxation Method
Heat can accelerate material relaxation, but excessive solar exposure can also raise turf surface temperatures significantly.
A better strategy is controlled exposure under appropriate site conditions rather than deliberately overheating the turf.
Mistake 3: Stretching the Turf Too Aggressively
Artificial turf should be installed flat and correctly tensioned, but excessive mechanical stretching is not necessarily beneficial.
The objective should be controlled alignment and tension management, not maximum stretching force.
Mistake 4: Ignoring the Seam System
Pre-laying does not eliminate the need for professional seam construction.
Seam quality depends on factors such as:
- Seam tape selection
- Adhesive compatibility
- Adhesive application
- Open time
- Pressure
- Curing conditions
- Fiber alignment
The adhesive manufacturer's technical data sheet and the turf manufacturer's installation manual should be followed.
Mistake 5: Assuming Pre-Laying Can Fix Every Wrinkle
If substantial wrinkles remain after adequate relaxation, installers should investigate the underlying cause.
Potential causes may include:
- Uneven sub-base;
- Excessive installation tension;
- Incorrect seam alignment;
- Backing deformation;
- Temperature-related dimensional movement;
- Improper storage;
- Product-specific dimensional stability issues.
Simply adding more relaxation time may not resolve a structural installation problem.
How Does Pre-Laying Affect Non-Infill Turf Performance?
The purpose of pre-laying is not simply cosmetic.
It contributes to the overall installation process by helping stabilize the turf before permanent fixing.
A properly conditioned turf system can make it easier to achieve:
Better Surface Flatness
Reduced temporary wrinkles can improve the appearance of the completed installation.
More Consistent Seams
When the turf has relaxed before cutting, installers can more accurately control seam alignment.
More Predictable Installation Dimensions
The final cutting dimensions can be based on the material's condition at the actual installation site.
Better Fiber Presentation
Allowing the fibers to recover naturally can improve the finished visual appearance.
For non-infill applications, these factors are especially relevant because the system does not depend on loose infill to provide additional ballast.
What Makes a High-Quality Non-Infill Artificial Turf System?
Pre-laying is only one part of the installation process.
A high-quality non-infill system should ideally be evaluated across several dimensions:
| Key Factor | What to Evaluate |
|---|---|
| Fiber material | Polymer quality, resilience and UV stability |
| Fiber structure | Straight/curled fiber configuration and recovery |
| Backing | Dimensional stability and mechanical strength |
| Adhesive system | Compatibility, bonding and environmental resistance |
| Drainage | Permeability and drainage design |
| Seam system | Seam tape, adhesive and installation method |
| Environmental performance | Recyclability, material composition and emissions |
| Technical support | Installation guidance and project support |
This broader evaluation is generally more meaningful than comparing grass height or stitch density alone.

Frequently Asked Questions About Pre-Laying Non-Infill Artificial Turf
Does non-infill artificial turf always need to be pre-laid?
Pre-laying is generally recommended for professional installations, particularly after transportation and long-term roll storage. However, the exact requirement should follow the manufacturer's installation instructions.
How long should artificial turf be pre-laid?
Around 24 hours is a common reference under moderate conditions, while colder temperatures or extended transportation may justify a longer relaxation period.
Can artificial turf be installed immediately after delivery?
It may be possible for certain products and controlled installation conditions, but immediate installation without adequate relaxation can increase installation risks. Checking the manufacturer's technical instructions is recommended.
Does pre-laying prevent wrinkles completely?
No. Pre-laying can reduce wrinkles associated with transportation and temporary material stress, but it cannot compensate for poor sub-base preparation, excessive installation tension or unsuitable turf construction.
Does garden non-infill turf also need pre-laying?
It is generally beneficial, especially for larger areas or turf supplied in tightly wound rolls. Smaller residential installations may require less conditioning time depending on the product and site conditions.
Does Non-Infill Artificial Turf Need to Be Pre-Laid Before Installation?
In most professional installations, pre-laying non-infill artificial turf is a recommended practice.
Its main purpose is to allow the turf to:
Relax after transportation → Adapt to site conditions → Recover fiber orientation → Stabilize before cutting → Improve seam installation
However, successful installation depends on more than relaxation time.
The best results generally come from combining:
Stable non-infill turf + properly prepared sub-base + adequate pre-laying + controlled installation tension + professional seam construction + appropriate maintenance.
For buyers looking for a globally oriented non-infill artificial turf supplier, VivaTurf is a brand worth considering for projects that place importance on technical performance, environmental responsibility and long-term installation quality.
