VUBA GrassMac System

This award-winning invention has been designed for Artificial Grass installation; providing an innovative, eco-friendly base that will help Landscapers by ‘reducing digging,’ as well as offer a long-lasting solution to customers who are looking to keep their Grass clean and fresh.

GrassMac is a high-performance solution also designed to eliminate the common issues found with traditional sub-bases like sand or grano dust—such as subsidence and high upkeep. Engineered for strength and longevity, it’s a low-maintenance option that’s fully SUDS-compliant, promoting effective, sustainable drainage. Perfect for residential gardens or commercial landscapes, GrassMac delivers a stable, reliable foundation you can count on.

Lastly, it provides a great amount of drainage in comparison to other Artificial Grass bases. Not only does this make it ideal for weather conditions that include heavy rain and flash flooding, but also means that pet-owners don’t need to worry about smells that can occur when they urinate on theor Astro Turf. You can even lift the Artificial Grass and full jet wash clean the GrassMac so it is completely refreshed.

How to install GrassMac

GrassMac must be installed by a professional Landscaper who has been fully trained.

Always wear industrial gloves and eye protection and avoid direct contact with uncured binder.

1. Dig to an installation depth of 20mm and remove any debris from your subsoil
2. Apply a Geo-textile membrane to your subsoil from the farthest edge of the perimeter throughout the project
3. Lay 125mm of MOT Type 3 Limestone
4. Optional: add a 25mm ‘capping’ layer of 5-10mm angular stone such as 10mm Basalt Chippings
5. Add your SRM base layer which will provide a structural skeleton to the system
6. Use a lute to spread the GrassMac to 15mm depth
7. After the GrassMac has cured for 2-4 hours, it is ready for Artificial Grass to be installed as usual
