Overview

GrassMac is an innovative, eco-friendly system designed to provide a base for artificial grass installations. It consists of three integrated layers: Vuba's Structural Reinforcement Mesh (SRM), GrassMac Resin, and a blend of recycled rubber and aggregate.

Specifically engineered to overcome common problems like subsidence and poor maintenance associated with traditional bases such as sand or grano dust, GrassMac offers a durable, low-maintenance alternative. Fully SUDS-compliant, it supports sustainable drainage and is ideal for both residential and commercial landscaping applications.

Layer System

Artificial Grass

The top layer consisting of your chosen artificial grass product.

GrassMac 20mm

This is the binder course layer, applied directly to the SRM base layer to enhance overall strength and durability.

SRM Base-Layer

The SRM spreads the load and allows fast overlayment, as well as providing a structural skeleton to the system.

Capping Layer

This is a 25mm layer of 5-10mm angular stone, well compacted on to the existing sub-base.

No Fines Stone / Clean Stone / MOT Type 3

To be installed at 125mm as standard and up to 225mm if there are concerns about permeability of the sub soil. Stone to be from 20mm up to 50mm in size.

Geotextile Membrane

A Geotextile Membrane ought to be installed from the farthest edge of the perimeter throughout the project. Ensure to correctly specify the grade of material.

Sub-Soil

It is important to determine the type of sub soil, as this will influence the specification of the sub-base and/or ground drainage requirements.
