Extensive green roofs are typically designed for shallow-rooting vegetation such as blanket sedum and are particularly suitable for roof areas where low maintenance and reduced structural loading are important.

The Enrich substrate provides a balanced growing environment with good porosity, drainage and water-holding characteristics while remaining lightweight enough for extensive roof applications.

Sedum roofs can provide a range of environmental and building-performance benefits, including rainwater attenuation, improved insulation, increased biodiversity and additional protection for the roof structure.

Green Roof Substrate for Sedum Planting

Extensive green roof systems are commonly planted with sedum because of its shallow root structure, resilience and relatively low maintenance requirements. The growing medium must provide enough moisture and nutrients to support healthy vegetation while maintaining sufficient drainage and aeration.

Enrich Extensive Green Roof Substrate is engineered to provide these characteristics in a consistent material suitable for shallow-depth roof systems.

Supporting Sustainable Drainage Systems

Green roofs are an important component of sustainable drainage strategies and can help reduce the rate at which rainwater enters conventional drainage systems. By retaining and delaying rainfall, they contribute to stormwater management and can help reduce pressure on urban drainage infrastructure.

They can also provide additional building insulation, create new habitats for plants and wildlife and contribute to improved environmental conditions within densely developed areas.

Manufactured to Green Roof Standards

Enrich Green Roof substrates are manufactured in accordance with F.L.L. guidelines and B.S. 8616:2019. Enrich has also received the Green Technology Award and Cré Innovation Award in recognition of its work in sustainable soil and growing media products.

Key benefits of using Enrich Green Roof Substrates include:

• Suitable for Sustainable Drainage Systems (SuDS)
• Supports vegetation in otherwise unused roof environments
• Lightweight material with good porosity and soil aeration
• Creates opportunities for urban biodiversity
• Manufactured using natural and recycled materials
• Helps retain carbon within the urban environment

Green Roof Substrate Supplied in Ireland

Enrich supplies extensive green roof growing media for landscape architects, roofing contractors, developers and green infrastructure projects throughout Ireland.

The product is suitable for a wide range of sedum roof systems and can form part of a broader sustainable landscape and stormwater management strategy.
