Shockpads vs Extra Sand Infill: Which Makes More Sense?

Shockpads and sand infill are not direct alternatives. Sand infill supports the artificial grass fibres and helps improve surface stability, while a shockpad sits beneath the grass to provide additional cushioning or, where specified and tested, impact performance. 

The right choice depends on how the area will be used, the grass specification and the installation build-up. Rather than focusing on one component, consider the complete system, including the base, underlay, artificial grass and specified infill.

Shockpads and Sand Infill Solve Different Problems

Shockpads change the construction beneath the artificial grass, while sand infill works within the pile. They perform different roles and should not be treated as interchangeable.

A shockpad sits between the prepared base and the grass, where it may provide additional cushioning or contribute to impact performance as part of a correctly specified system. Sand infill is brushed into the fibres to support the pile, add ballast and improve surface stability. Both components still rely on proper base preparation, and any infill should match the artificial grass manufacturer's guidance.

Many homeowners assume extra sand creates the same effect as a shockpad. This is not the case. Adding more infill than recommended cannot replace an underlay or provide verified impact performance.

What Does a Shockpad Do?

A shockpad creates a resilient layer beneath artificial grass and may improve cushioning or impact performance when it forms part of a correctly specified system. Installed between the prepared base and the grass backing, it changes how the surface responds underfoot while increasing the overall build-up height. 

Comfort depends on the grass, base and installation quality, not the shockpad alone. For play areas, schools and commercial projects, any impact performance should be supported by documented testing for the complete system. 

Compare artificial grass shockpads according to compatibility, intended use and verified product information rather than thickness or price alone. 

Potential Benefits

Important Considerations

Additional cushioning

Requires a stable, prepared base

May contribute to impact performance when specified

Performance depends on the complete system

Creates a more resilient build-up

Adds to the finished installation height

Compatible with many artificial grass systems

Product compatibility should always be checked

Comfort Underfoot

A resilient underlay may create a less rigid feel than grass installed directly onto a hard base. Comfort remains subjective and is influenced by the grass pile, base preparation, shockpad specification and installation quality. No single product can guarantee a particular feel underfoot.

Impact Performance

Impact performance should always be supported by verified testing or documented system specifications. Thickness alone does not confirm suitability for child-use surfaces or play areas. Projects with formal safety requirements may require professional specification before installation.

Finished Height and Transitions

Adding a shockpad increases the depth of the installation. Check finished levels around door thresholds, paving, edging, drainage channels and neighbouring surfaces before work begins. Careful planning helps avoid awkward transitions and raised edges.

What Is Sand Infill Used For?

Sand infill is brushed between the artificial grass fibres to support the pile, add ballast and improve surface stability. The correct sand type and quantity depend on the grass product and the manufacturer's installation guidance.

Why More Sand Is Not Always Better

Adding more sand than recommended will not create the same cushioning as a shockpad. Excess infill can bury the fibres, affect their movement, alter the lawn's appearance and make maintenance more difficult. Always follow the specified quantity for your chosen artificial grass, as requirements vary between products and installation systems.

How Do They Affect Comfort Underfoot?

A shockpad is more likely to change the underlying feel of the surface, while sand infill mainly supports the fibres and stabilises the grass. Neither should be assessed without considering the base preparation and artificial grass specification.

The same grass can feel different depending on the installation build-up. A lawn laid over compacted aggregate may feel firmer than one installed with a compatible shockpad. Grass pile height, density and the specified infill also influence comfort. Samples are useful for comparing products, although they cannot fully reflect how the finished installation will feel underfoot.

How Do Shockpads and Sand Infill Compare for Impact Protection?

Shockpads may contribute to tested impact performance, while extra sand infill should never be treated as a substitute for an impact-attenuating layer. Any safety claim should apply to the complete installed system, not an individual component.

A surface that feels softer underfoot is not necessarily impact-rated. Projects for schools, nurseries and playgrounds may require documented performance for the full installation. Adding more sand than recommended will not provide the same level of protection and may affect the appearance and performance of the artificial grass.

What Are the Drainage and Stability Differences?

Drainage depends on the preparation and permeability of the complete installation. Shockpads and sand infill can influence water movement and stability, although neither can resolve problems caused by a poorly prepared base.

Water should pass through the grass backing and into a suitable sub-base before draining away. Pooling is usually linked to incorrect levels or inadequate preparation rather than the absence of a shockpad or additional sand.

When Might Extra Sand Infill Be Enough?

Additional shock absorption is not necessary for every garden. Where the objective is fibre support, ballast and everyday domestic use, the specified sand infill may provide everything the installation requires.

Decorative front gardens, seating areas and lawns without formal impact requirements frequently perform well using the recommended infill quantity on a stable, properly prepared base. Avoid treating "extra" as permission to exceed the manufacturer's guidance, since excessive infill may bury the pile and affect the finished appearance.

When Is a Shockpad the Better Choice?

A shockpad may be the better option where additional cushioning or verified impact performance is a priority. The specification should always match the intended use and artificial grass system.

Family play areas, hard existing bases and some commercial projects may benefit from a compatible shockpad. Schools, nurseries and other environments with formal performance requirements may also require documented system evidence rather than selecting a product based on thickness alone.

Can You Use Shockpads and Sand Infill Together?

Yes. Many artificial grass systems use both components together. The shockpad sits beneath the grass, while the specified sand infill supports the fibres above.

This arrangement does not duplicate performance because each layer performs a separate role. Always check compatibility, follow the recommended installation sequence and consider finished height before ordering materials.

Can You Use Shockpads and Sand Infill Together?

Yes. Shockpads and sand infill are commonly used together when the artificial grass system is designed for both. The shockpad sits beneath the grass to provide cushioning, while the specified sand infill supports the fibres above. Since each component performs a different role, using both is not unnecessary duplication. 

Always check product compatibility, follow the recommended installation sequence and use the correct infill quantity for your chosen grass. Remember to allow for the finished build-up height around doors, edging and adjoining surfaces before installation begins.

What Should You Consider Before Choosing?

Choose the system according to the intended use, required performance, grass specification, prepared base and finished surface level before comparing prices.

Ask yourself:

  • How will the area be used?

  • Who will use it?

  • Does the grass require sand infill?

  • Is additional cushioning desirable?

  • Are there formal impact requirements?

  • Will the finished height affect doors or paving?

  • Has the base been prepared correctly?

  • Do you need technical advice before ordering?

Frequently Asked Questions

Can Extra Sand Make Artificial Grass Softer?

It may slightly influence surface feel by supporting the fibres, although it does not replace an underlay or shockpad.

Does Every Artificial Lawn Need Sand Infill?

No. The answer depends on the artificial grass product and its installation guidance.

Does Every Artificial Lawn Need a Shockpad?

No. Shockpads are selected according to the intended application, desired comfort and any required performance.

Are Thicker Shockpads Always Better?

No. Thickness should match the project requirements, compatible grass system and installation specification.

Can a Shockpad Fix an Uneven Base?

No. The base should always be correctly prepared before installation.

Can Sand Infill Improve Drainage?

Drainage depends primarily on the complete construction and prepared base rather than the infill alone.

Shockpads and sand infill should be selected for different reasons rather than treated as competing products. Use the specified infill to support the artificial grass system, and consider a shockpad where additional cushioning or verified impact performance is required.

Before placing an order, check the grass specification, confirm the finished build-up and ensure every component is compatible with the intended application. Planning a school, playground or commercial project may also justify technical advice before selecting individual products.
