Environmental Paving Solutions

Grass Concrete Limited's long history began with the invention of the now world-renowned GRASSCRETE paving system. Since then, our range has expanded to include pre-cast paving under the GRASSBLOCK and TRI-LOCK headings, together with our plastic GRASSROAD system.

Grass paving systems, with their natural draining characteristics, offer an ideal means of achieving a balanced Sustainable Urban Drainage System (SUDS), that can eliminate an otherwise costly drainage infrastructure.

This commitment to the environment doesn't end there; our product range includes many elements of recycled materials in both manufacture and on-site installation.
