Drainage Plate System Using G-CORE
A clean, fast and sustainable foundation for high-performance drainage systems
A modular, free-draining drainage layer for sports fields, artificial turf systems, landscaping and engineered surface applications.
G-CORE creates a stable, load-spreading, high-performance drainage layer that helps manage water efficiently, reduce reliance on traditional drainage aggregates and support long-term surface performance
Designed for modern landscaping and construction projects across the UK and worldwide.
Typical Drainage Plate System Build Up
A visual concept showing how G-CORE works as a drainage layer beneath the finished surface.
Improves water movement below the surface while reducing the need for deep aggregate drainage layers.
Suitable for sports field drainage, landscaping schemes and design-led terrace or podium applications.
Why Choose G-CORE?
A single modular drainage plate system delivering performance, speed, and sustainability across sports, landscaping, and civil groundwork applications.
Supports Water Movement
The open modular structure provides a continuous route for water movement beneath compatible finished surfaces.
Load-Spreading Structure
Helps maintain stability while supporting surface loads in active-use areas.
Reduced Aggregate Requirement
Minimises the need for deep stone drainage layers and heavy imported materials.
Cleaner Installation
Less spoil, less mess, and fewer heavy materials moving around site.
Modular Drainage Plate System
Click-together panels form a continuous, engineered drainage layer.
Versatile Applications
Suitable for sports fields, artificial turf, landscaping, terraces and podium concepts.
Why the Drainage Layer Matters
Surface performance depends on what happens below. If water cannot move away efficiently, the result can be waterlogging, saturated ground, reduced usability, and long-term instability beneath the surface.
Traditional drainage methods often rely on deep stone layers and heavy bulk fill. G-CORE offers a more controlled modular alternative by forming a precision-engineered drainage plate system with built-in void space for water movement.
Surface Water Build-Up
Poor drainage can reduce usability and affect the long-term condition of the finished surface.
Ground Saturation
Excess moisture below the surface can weaken performance and create soft or unstable areas.
Heavy Traditional Drainage Builds
Deep drainage stone layers increase excavation, deliveries, labour, and site disruption.
How G-CORE Works?
The G-CORE system forms a rigid, free-draining layer that sits between the prepared ground and the finished surface. The result is a stable, high-performance drainage solution that manages water efficiently while reducing the need for traditional aggregate systems.
1
Prepare the ground
Level and prepare the formation to suit the project falls and drainage design.
2
Click panels together
Lay G-CORE panels in rows, locking them together to create a continuous drainage layer.
3
Connect drainage pathways
Incorporate drainage pathways, outlets, or service routes where needed to support effective water movement through the system.
4
Add your finished surface
Apply the final surface such as artificial turf, sports field systems or landscaping finishes directly over the drainage layer.
Where G-CORE Drainage Plates Can Be Used
Designed for applications where reliable drainage, structural support, and cleaner installation matter.
Sports Fields & Pitches
Supports sports field drainage by helping keep surfaces drier, more usable and more consistent.
Commercial Landscaping
Suitable for public realm and commercial schemes where surface water management is a priority.
Artificial Turf Installations
Ideal below synthetic turf systems where efficient drainage and stable support are essential.
School & Leisure Areas
Helps manage drainage beneath high-use external surfaces.
Technical Benefits
High-performance drainage
Creates a continuous free-draining layer that allows water to move efficiently beneath the surface.
Stable load support
Forms a rigid, load-spreading structure that maintains surface stability under foot traffic and light loads.
Adaptable system design
Compatible with membranes, sports turf systems and project-specific surface finishes.
Reduced aggregate requirement
Minimises the need for traditional stone drainage layers, reducing material usage and site disruption.
Frequently Asked Questions
Answers to common questions about ground drainage, drainage layers and using G-CORE beneath sports, landscaping and external surfaces.
How can you improve drainage beneath an outdoor surface?
Good drainage beneath an outdoor surface requires a build-up that allows water to move away effectively without compromising the stability of the finished surface. The correct solution depends on ground conditions, falls, outlets and intended use. G-CORE can form a free-draining modular layer within a properly designed system, providing void space for water movement while supporting the surface above.
How do you prevent waterlogging under artificial turf and sports surfaces?
Preventing waterlogging requires water to pass through the surface and drainage layers before being directed towards suitable drainage pathways or outlets. The complete design depends on the surface, ground conditions and site drainage strategy. G-CORE creates a continuous free-draining layer beneath compatible sports and artificial-turf systems, helping water move below the finished surface.
Is there an alternative to using deep layers of drainage stone?
Yes. Modular drainage layers can provide an alternative to some conventional deep aggregate drainage build-ups where suitable for the project design. G-CORE creates a connected void beneath the finished surface for water movement and can reduce reliance on bulk drainage aggregate. The required build-up will depend on loading, ground conditions, drainage design and the intended surface.
Can you improve ground drainage without deep excavation?
In suitable applications, drainage can be improved without relying solely on deep aggregate-based construction. A modular drainage layer such as G-CORE can reduce the depth and volume of traditional drainage material required while maintaining a route for water movement. However, excavation requirements depend on existing levels, soil conditions, drainage outlets, loading and the complete project design.
How does drainage work on roof terraces and podium areas?
Roof terraces and podium areas typically require a drainage layer that moves water towards designed outlets while working with the waterproofing and finished surface build-up. G-CORE can form part of a compatible modular drainage system, but falls, outlets, waterproofing, loading and structural requirements must be considered as part of the overall project design.
Can G-CORE supply and install a drainage plate system for my project?
Yes. G-CORE can provide product supply and professional installation for suitable drainage plate projects.
