Fake Grass Ground Preparation: A Buyer’s Guide

Installing fake grass is not simply a matter of rolling out a green surface and fixing the edges.

For a landscaping contractor, school procurement team, landscape designer, or turf importer, the performance of a finished project depends heavily on what is underneath the turf.

A poorly prepared base can cause:

• Uneven surfaces

• Standing water

• Turf movement

• Visible seams

• Premature fiber wear

• Weed growth

• Higher maintenance costs

• Early replacement

A properly prepared base, by contrast, gives fake grass carpet a stable foundation and allows the drainage system to work as intended.

For project buyers, the important question is therefore not only “Which fake grass should we buy?” but also:

“What ground preparation and turf system will give us the lowest practical lifecycle cost for this site?”

This guide explains how to prepare ground under fake grass, how to select the appropriate base, and when different turf systems make sense for landscaping, schools, commercial developments, and larger outdoor projects.

Why Ground Preparation Matters for Fake Grass Projects

The turf is only one part of a complete artificial surface system.

A typical outdoor installation includes:

Prepared ground → compacted sub-base → leveling layer → drainage → fake grass carpet → fixing/seaming system

If one part of the system is poorly designed, the turf itself cannot completely compensate for it.

For example, even a high-quality fake grass carpet can develop drainage problems if rainwater cannot move through the base.

The same applies to stability. A durable fake grass product installed over an unstable or poorly compacted surface may still develop dips, movement, or uneven areas.

For project buyers, good ground preparation provides four practical benefits:

This is particularly important for schools, commercial landscapes, parks, hotels, residential developments, and other areas where the surface needs to remain visually consistent.

Step 1: Assess the Existing Ground Before Ordering Fake Grass

Before choosing fake grass, inspect the installation area.

Do not start by selecting the pile height or color. Start with the site.

Check:

• Existing soil condition

• Ground slope

• Drainage routes

• Soft or unstable areas

• Existing vegetation

• Tree roots

• Large stones

• Concrete or asphalt

• Existing irrigation systems

• Utility lines

• Expected pedestrian traffic

A residential garden and a school playground may use similar-looking fake grass carpet, but their ground preparation requirements can be very different.

Ask these questions before finalizing the specification:

1. Will the area receive light, moderate, or heavy traffic?

2. Does rainwater currently drain quickly?

3. Is the existing ground clay-heavy or prone to water retention?

4. Will the site require frequent washing?

5. Are there nearby buildings where water runoff must be controlled?

6. Does the project require a specific environmental or product document?

7. Will the same turf specification need to be reordered later?

This information should be shared with the turf supplier before bulk production.

For large projects, fake grass specifications should be matched to the installation environment, rather than selecting a product simply because it has a higher pile height or higher density.

Step 2: Remove Existing Grass, Vegetation and Unstable Material

If natural grass or vegetation already covers the area, remove the organic layer before installing fake grass.

Roots and organic material can decompose over time and create voids underneath the finished surface.

The preparation normally involves:

• Removing natural grass and roots

• Removing weeds

• Clearing loose soil

• Removing stones and debris

• Removing unstable topsoil where necessary

• Excavating to the required project depth

The required excavation depth depends on the existing ground, drainage design, traffic level, climate, and final surface specification.

For larger commercial or sports projects, the base should be designed according to the engineering requirements of the site rather than using one fixed depth for every project.

Why this matters

A common mistake is to install fake grass carpet directly over uneven natural soil because the surface looks acceptable before installation.

Once the turf is installed, small irregularities can become much more visible.

For contractors, correcting the base before installation is usually much easier than repairing an uneven finished surface.

Step 3: Build a Stable Sub-Base

After excavation and site clearance, the next priority is the sub-base.

For many outdoor fake grass installations, crushed aggregate or similar compactable material is used to create a stable foundation.

The exact material and thickness should be selected according to:

• Soil conditions

• Local drainage requirements

• Expected traffic

• Climate

• Surface area

• Project engineering specifications

The objective is simple:

Create a stable layer that supports the turf while allowing water to move away from the surface.

A practical base structure may include:

Existing ground

↓

Compacted aggregate sub-base

↓

Fine leveling layer

↓

Drainage-compatible fake grass carpet

This is more important than simply purchasing a high-density turf.

A premium-looking fake grass product cannot correct a poorly constructed foundation.

Step 4: Compact the Base Properly

Compaction is one of the most important steps in fake grass ground preparation.

If the base is loose, it may settle unevenly after installation.

That can lead to:

• Depressions

• Surface movement

• Water accumulation

• Uneven appearance

• Stress on seams

• Additional repair work

A plate compactor or suitable roller is normally used depending on the project scale and base material.

For larger projects, the base should be compacted in controlled layers rather than attempting to compact a deep loose layer in one operation.

Check the surface after compaction

Walk the area and inspect for:

• Soft spots

• Low areas

• High areas

• Loose aggregate

• Visible settlement

• Drainage problems

Use a straightedge or appropriate surveying equipment for larger installations.

The goal is not merely to make the ground “look flat.”

The goal is to create a stable and predictable installation platform for the fake grass system.

Step 5: Design Drainage Before Installing Fake Grass

Drainage is often underestimated when buyers compare fake grass products.

The drainage performance of a finished installation depends on more than the turf backing.

It is a system involving:

Turf perforations + base material + ground slope + drainage infrastructure

XiHY's landscaping artificial grass products, for example, use backing systems with drainage holes, while the landscaping range is offered in different pile heights, densities, colors and backing configurations.

Good drainage helps reduce:

• Standing water

• Long drying periods

• Surface contamination

• Mud around the perimeter

• Moisture-related maintenance

• Problems caused by heavy rainfall

For rainy climates, drainage should be discussed before selecting the final fake grass carpet.

Important procurement point

Do not ask a supplier only:

“Does your fake grass have drainage holes?”

Also ask:

• What is the backing construction?

• How is water expected to move through the system?

• What base is recommended?

• Is additional drainage infrastructure required?

• Is the product suitable for frequent washing?

• Can drainage performance documentation be provided?

This produces a much more useful specification than comparing turf by appearance alone.

Step 6: Add a Leveling Layer

After the structural base has been compacted, a finer material may be used to create the final leveling surface.

The purpose is to remove small irregularities and provide a consistent surface for the fake grass carpet.

A properly leveled surface helps:

• Reduce visible undulations

• Improve turf appearance

• Improve installation accuracy

• Reduce stress on seams

• Make final fixing easier

For large projects, the leveling tolerance should be agreed during project planning.

Do not assume that every landscape project requires the same tolerance.

A private garden, hotel landscape, school area, and sports field have different performance requirements.

Step 7: Install a Weed Barrier Where Appropriate

A weed barrier can be useful in many ground-level landscaping installations.

It can help reduce weed growth from below the fake grass and separate the turf system from the underlying soil.

However, it should not be treated as a substitute for proper excavation and base preparation.

If organic material and active roots remain underneath the installation, simply adding a fabric layer does not solve the underlying problem.

For a durable fake grass installation, the sequence matters:

Remove vegetation → prepare the ground → build the base → compact → level → install the appropriate separation/barrier layer → lay turf

The exact system should be adapted to the project.

Infill vs. Non-Infill Fake Grass: Which System Fits the Project?

One of the most important decisions for larger projects is whether the selected fake grass system requires infill.

These systems should not be treated as universally interchangeable.

Infill Fake Grass

Infill systems use materials such as sand or rubber granules to support the fibers and contribute to surface performance.

XiHY's football turf range, for example, includes infill systems using sand or rubber, with the infill helping support the fibers and contribute to cushioning and playing characteristics.

Advantages

• Can provide additional fiber support

• Can improve cushioning in sports applications

• Suitable for specific high-use sports systems

• Can be designed around defined performance requirements

Limitations

• Requires additional material

• Needs periodic redistribution or maintenance

• Loose infill can migrate outside the field

• Cleaning and replacement can become part of lifecycle maintenance

• Certain infill materials may create dust or disposal considerations

For sports fields, these trade-offs may be justified because the infill contributes to the required playing characteristics.

Non-Infill Fake Grass

Non-infill systems are designed to operate without loose rubber or sand infill.

XiHY currently offers non-infill football turf specifically positioned as a lower-maintenance alternative that eliminates the need for rubber or sand infill.

Advantages

• No routine loose infill replenishment

• Cleaner surface management

• No loose rubber or sand to redistribute

• Less material handling during maintenance

• Potentially simpler end-of-life material management

Limitations

• Not suitable for every sports application

• Performance depends heavily on fiber construction and backing

• May require a different base or shock-absorption design

• Initial material cost can be higher for certain specifications

For landscaping, schools, commercial outdoor areas, or projects where loose infill is undesirable, a non-infill configuration can be worth evaluating.

Procurement comparison

The key point is not that one system is always better.

The best fake grass system is the one that matches the site's performance requirements, maintenance capability and lifecycle budget.

Fake Grass Carpet and Lifecycle Cost: Look Beyond the Purchase Price

A common procurement mistake is comparing products only by price per square meter.

For a project, the real cost can include:

Turf + base preparation + installation + maintenance + cleaning + repairs + infill + replacement + disposal

This is why a cheaper fake grass carpet is not necessarily the lower-cost option over the entire project lifecycle.

Example

A lower-cost turf may have:

• Lower purchase price

• Basic fiber construction

• Lower initial installation cost

But a higher-specification product may offer:

• Better recovery after traffic

• Better UV stability

• More suitable backing

• Better drainage

• Longer expected service life

• Lower maintenance frequency

The right comparison is therefore:

Total lifecycle cost ÷ expected service period

rather than simply:

Purchase price ÷ square meter

XiHY's landscaping range includes products with different pile heights, densities, colors, backing systems and durability levels, allowing specifications to be matched to the actual project rather than using one specification for every site.

How to Prepare Fake Grass for Different Project Types

Residential and Villa Landscaping

For residential gardens, the main priorities are usually:

• Natural appearance

• Comfort

• Drainage

• UV resistance

• Easy cleaning

• Reasonable installation cost

A medium-pile fake grass carpet can often provide a practical balance between appearance and maintenance.

There is little value in paying for a highly specialized sports turf specification if the area is primarily decorative.

School and Kindergarten Projects

School projects require a different approach.

The turf may experience:

• High daily foot traffic

• Running and play

• Frequent cleaning

• Rain exposure

• Heavy use in specific zones

Procurement teams should therefore evaluate:

• Fiber resilience

• Drainage

• Surface comfort

• Backing stability

• UV performance

• Cleaning requirements

• Product documentation

For these projects, selecting fake grass purely by appearance can create problems later.

Commercial Landscaping

Hotels, shopping centers, office developments, parks and public spaces normally require greater visual consistency.

Important considerations include:

• Batch consistency

• UV resistance

• Wear resistance

• Drainage

• Color stability

• Easy maintenance

• Replacement availability

For large areas, it is particularly important that future replacement material can reproduce the original specification.

This is one reason why working directly with a fake grass manufacturer can be useful for large projects.

XiHY provides customizable options covering pile height, density, color, yarn structure, backing and drainage requirements, while its factory-direct model is designed to support sample confirmation, bulk production and repeat specifications.

What Overseas Buyers Should Ask a Fake Grass Supplier

Before placing a bulk order, procurement teams should request more than a price list.

Product specification

Ask for:

• Pile height

• Yarn material

• Yarn shape

• Density

• Dtex/denier

• Gauge

• Backing construction

• Drainage design

• Roll dimensions

• UV-resistance information

• Warranty conditions

Project support

Also confirm:

• Can the supplier provide samples?

• Can specifications be customized?

• Can the same specification be reproduced for repeat orders?

• What is the production lead time?

• What installation guidance is available?

• Can the supplier support large-volume delivery?

• What technical documentation is available?

XiHY currently lists free standard samples for several landscaping products, with customized samples handled separately, and lists typical landscaping lead times in the 7–25 day range depending on order details.

Environmental and Compliance Considerations for European Projects

For projects destined for European markets, environmental and product compliance documentation should be considered during procurement rather than after production.

Buyers should request the documentation relevant to the actual product and application.

Depending on the project, this may include:

• Material information

• Product test reports

• UV-performance documentation

• Chemical compliance information

• CE-related documentation where applicable

• REACH-related documentation where applicable

An important distinction is that REACH is an EU chemical regulatory framework, while CE marking applies to products within the scope of applicable EU legislation. Buyers should therefore ask for the specific supporting documentation rather than treating “CE/REACH certified” as a generic environmental claim.

XiHY states that relevant CE and REACH-related documentation can be provided according to project requirements.

This approach is particularly important for schools, public projects, commercial developments and European procurement processes.

Maintenance Starts With the Ground

Even the best fake grass still requires basic maintenance.

The difference is that maintenance is generally simpler than maintaining natural grass.

A practical maintenance program may include:

• Removing leaves and branches

• Rinsing surface dust

• Cleaning spills

• Removing organic debris

• Brushing high-traffic areas

• Checking seams

• Checking perimeter fixing

• Keeping drainage channels clear

XiHY recommends regular rinsing and brushing for its landscaping turf range, with some products specifying quarterly maintenance under normal conditions.

For projects using infill

Maintenance may additionally include:

• Checking infill distribution

• Brushing the surface

• Replenishing lost infill

• Monitoring material migration

This is one reason why project owners should consider maintenance labor and material consumption when comparing an infill system with a non-infill alternative.

Conclusion: Prepare the Ground Before Choosing the Turf

The success of a fake grass project starts below the surface.

A good installation is not simply:

Buy turf → roll it out → fix the edges

It is:

Assess the site → prepare the ground → build the base → control drainage → level and compact → select the right fake grass system → install correctly → maintain it according to use

For residential landscaping, a practical and attractive specification may be enough.

For schools, commercial landscapes and public areas, buyers may need stronger fiber resilience, better drainage and more durable backing.

For sports projects, the choice between infill and non-infill systems should be based on the required playing characteristics, maintenance plan and lifecycle requirements.

For overseas contractors and importers, supplier capability is another part of the decision. XiHY operates as a China-based artificial grass manufacturer and provides customizable turf specifications, standard product samples, bulk production support and project-oriented technical assistance.

If you are planning a landscaping, school, commercial or sports project, provide the installation area, application, expected traffic, climate and preferred pile height when requesting a turf quotation. This gives the supplier enough information to recommend a complete fake grass carpet and ground-preparation system, rather than quoting a generic turf roll.
