What Is a Grass Stone Mould and Why Is It Essential for Permeable Pavement Projects

A Grass Stone Mould is a specialized concrete mould used to produce permeable grass stones or grass pavers that combine structural strength with ecological benefits. These products are widely applied in parking lots, sidewalks, gardens, and municipal infrastructure to support drainage, reduce urban flooding, and enhance green spaces.

In this in-depth guide, we explore how grass stone moulds work, their types, applications, manufacturing process, and how to choose the right mould for your block production line. This article is designed for contractors, block manufacturers, developers, and urban planners seeking sustainable paving solutions.

1. What Is a Grass Stone Mould?

A Grass Stone Mould is a precision-engineered steel or alloy mould designed for concrete block machines. It shapes fresh concrete into grass stones—also known as grass pavers or lawn blocks—featuring hollow structures that allow grass growth and water infiltration.

Unlike conventional paving moulds, grass stone moulds create blocks that balance:

• Load-bearing capacity
• Water permeability
• Vegetation growth
• Long-term durability

These moulds are commonly used with automatic and semi-automatic block making machines, including systems developed by Quangong Machinery Co., Ltd., a global leader in concrete block production technology.

2. How Does a Grass Stone Mould Work?

Grass stone moulds function by forming cavities or lattice patterns within concrete blocks. During vibration and compression, the mould ensures uniform density while maintaining precise void dimensions.

Basic Working Steps

1. Concrete mix is fed into the mould cavity
2. Vibration and pressure compact the mixture
3. Mould forms hollow grass chambers
4. Blocks are demoulded and cured

After installation, soil and grass seeds fill the hollow sections, enabling natural vegetation growth while supporting vehicle or pedestrian loads.
