These are not just for film use. GRP or glassfibre artificial rocks are very durable and can be used in landscaping schemes or green roofs where weight is an issue. GRP is a hard material and can be damaged with rough handling. Apart from GRP, lightweight rocks can be made in polyurethane and polyethylene or plastic. The poly or plastic rocks can be thrown around without damage. Ideal for avalanches, landslips and rock falls.
