Artificial Grass Bases Using G-CORE
A clean, fast and sustainable foundation for artificial grass installation.
G-CORE is a modular ground preparation system designed to replace traditional hardcore sub-bases. It delivers superior drainage, faster installation and a cleaner, more efficient foundation for modern landscaping projects.
Designed for modern landscaping and construction projects across the UK and worldwide.
Typical Artificial Grass Build Up
A visual concept showing how G-CORE sits within the artificial grass system.
Replaces traditional hardcore bases, reducing excavation and imported aggregate.
Perfect for artificial grass in gardens, commercial landscaping, and roof terrace systems.
Why Choose G-CORE?
A single modular system that delivers strength, speed, and sustainability across domestic, commercial, and civil groundworks.
Hardcore Replacement
Eliminates or reduces the need for bulk aggregate and deep excavation depending on the design.
Sustainable Ground Preparation
Manufactured from 99% recycled plastic to support lower-impact construction.
Soakaway Drainage Performance
Supports natural water movement below the finished surface in ground-level installations.
Cleaner Installation
Less spoil, less mess and fewer heavy materials moving around site.
Modular Sub-Base System
Click-together panels form a stable, load-spreading raft foundations.
Versatile Applications
Suitable for gardens, landscaping projects, play areas and roof terrace concept.
Why the Artificial Grass Base Matters
Artificial grass only performs as well as the foundation below it. If the base is unstable, poorly drained or unevenly compacted, the final surface can develop soft spots, pooling, settlement and costly remedial work.
Traditional bases often rely on deep excavation, imported hardcore and heavy compaction. G-CORE offers a cleaner, more controlled alternative by creating a precision-engineered modular sub-base.
Poor Drainage
Water retention can affect usability, appearance and long-term performance.
Uneven Settlement
Inconsistent support below the turf can lead to dips and visible surface movement.
Heavy Construction Process
Deep digs, spoil removal and aggregate deliveries increase labour and disruption.
How G-CORE Works?
The G-CORE system forms a rigid, load-spreading raft that sits between prepared ground and the finished surface. The result is a stable, well-drained foundation with far less bulk material than traditional methods.
1
Prepare the ground
Excavate and level the formation to suit the project design and finished levels.
2
Click panels together
Lay G-CORE panels in rows, locking them together to cover the full footprint of the project.
3
Fill & reinforce if required
Use suitable fill material where specified and incorporate service routes for pipes or cables.
4
Add your finished surface
Install membrane, optional shock pad and artificial grass over the completed build-up.
Where G-CORE Can Be Used
Designed for multiple groundwork and landscaping applications where a stable, sustainable sub-base is required.
Domestic Gardens
Ideal for family lawns, pet areas, and low-maintenance landscape projects.
Roof Terraces
Can form part of a terrace surface strategy where drainage and loading are fully considered.
Commercial Landscaping
Suitable for offices, hospitality spaces, schools, and public realm schemes.
Podium & Specialist Surfaces
Useful for design-led projects requiring a lightweight, modular foundation concept.
Technical Benefits
Stable support
Creates a continuous load-spreading layer beneath the turf system.
Drainage performance
Designed to support efficient water movement under the finished surface.
Adaptable specification
Can be paired with membranes, shockpads, and project-specific top layers.
Reduced site disruption
Helps minimise aggregate handling, waste, and vehicle movements on site.
Frequently Asked Questions
Answers to common questions about using G-CORE as a foundation for artificial grass installations.
What is the best base for artificial grass?
The best base for artificial grass is a stable, level and well-drained foundation suited to the ground conditions and intended use. Traditional installations commonly use compacted aggregate such as MOT Type 1. G-CORE provides a modular alternative to traditional hardcore, creating a stable, load-spreading foundation while supporting drainage and reducing reliance on bulk aggregate.
What should you put underneath artificial grass?
Artificial grass should be installed over a stable, level and free-draining foundation. A traditional build-up may include prepared ground, a geotextile membrane, compacted aggregate and a levelling layer before the artificial grass is installed. G-CORE can replace or reduce the traditional hardcore element, providing a modular foundation beneath the finished surface.
How do you create good drainage under artificial grass?
Good drainage under artificial grass starts with correctly prepared ground and a permeable foundation that allows water to move away from the surface. The appropriate drainage solution depends on soil conditions, levels and the overall build-up. G-CORE's open modular structure supports water movement through the foundation while providing a stable base beneath the artificial grass system.
Do you need MOT Type 1 under artificial grass?
MOT Type 1 is commonly used as a traditional sub-base beneath artificial grass, but it is not the only solution. Alternative foundation systems can be used where appropriate for the ground conditions and project requirements. G-CORE is designed as a modular alternative to traditional hardcore, helping reduce imported aggregate, excavation and spoil removal on suitable projects.
How can you reduce excavation when installing artificial grass?
Excavation can be reduced by using a foundation system that requires less traditional bulk aggregate beneath the finished surface. G-CORE can reduce the amount of excavation, imported hardcore and spoil removal required on suitable artificial grass projects. The actual ground preparation needed will depend on existing levels, soil conditions, drainage requirements and the project specification.
Can G-CORE install the base for my artificial grass project?
Yes. G-CORE provides professional foundation installation for suitable artificial grass projects. Based in Daventry, Northamptonshire, our team can assess your project requirements and recommend an appropriate G-CORE foundation solution. Send us your postcode, approximate project size, photographs of the existing area and details of the proposed installation to request a quotation.
