Our Bio Diverse Lava-Based Substrate is a premium natural growing medium designed to support healthy plant growth while promoting a thriving ecosystem within ponds, wetlands, filtration systems, and planted environments.

Produced from carefully selected volcanic lava rock, this highly porous substrate provides exceptional surface area for beneficial bacteria, creating the ideal conditions for natural biological filtration. Its unique structure encourages the establishment of diverse microbial communities that help break down organic waste, improve water quality, and support long-term ecological balance.

The substrate also offers excellent root anchorage for aquatic and marginal plants, allowing roots to establish quickly while maintaining optimal access to water, oxygen, and nutrients. Its durable composition resists compaction, ensuring consistent performance over many years.

Key Benefits
Naturally porous volcanic lava structure
Encourages beneficial bacteria and microbial diversity
Supports biological filtration and nutrient cycling
Excellent root support for aquatic and marginal plants
Improves water quality naturally
Long-lasting and resistant to compaction
Sustainable and environmentally friendly solution
Suitable for ponds, wetlands, biofilters, aquascaping, and habitat creation projects

Our Bio Diverse Lava-Based Substrate is ideal for:

Natural swimming ponds
Wildlife ponds
Constructed wetlands
Reed beds and biofiltration systems
Aquatic planting schemes
Rain gardens and sustainable drainage systems (SuDS)
Habitat enhancement and biodiversity projects

By combining natural volcanic materials with ecological design principles, our Bio Diverse Lava-Based Substrate helps create healthier, more resilient environments that support both plant growth and biodiversity.

Our Extensive Lava-Based Substrate is specifically developed for extensive green roof systems, delivering the perfect balance of drainage, aeration, water retention, and long-term structural stability.

Manufactured from high-quality volcanic lava aggregates, this lightweight substrate provides an ideal growing environment for sedums, wildflowers, grasses, and other drought-tolerant vegetation commonly used in extensive roof applications. The naturally porous structure of lava rock helps retain moisture during dry periods while allowing excess water to drain freely, reducing the risk of waterlogging and root stress.

Designed to support sustainable urban greening, our Extensive Lava-Based Substrate promotes healthy plant establishment, enhances biodiversity, and contributes to improved rainwater management. Its durable mineral composition ensures long-lasting performance with minimal degradation over time.

Key Benefits
Lightweight solution for extensive green roof systems
Excellent water retention and drainage characteristics
Promotes strong root development and plant health
Naturally porous volcanic lava structure
Supports sedums, wildflowers, grasses, and native planting schemes
Helps improve stormwater management
Enhances biodiversity and urban habitat creation
Durable, stable, and long-lasting performance

Our Extensive Lava-Based Substrate is suitable for:

Extensive green roofs
Biodiverse roof systems
Wildflower roofs
Sedum roofs
Brown roofs and habitat roofs
Sustainable urban drainage projects (SuDS)
Ecological enhancement schemes

By combining natural volcanic materials with proven green roof technology, our Extensive Lava-Based Substrate provides a reliable foundation for creating sustainable, resilient, and environmentally beneficial rooftop landscapes.

At Wraxalls, we understand that no two projects are the same. That's why we offer bespoke, made-to-order substrate blends tailored to the specific requirements of your scheme, planting palette, performance criteria, and project objectives.

In addition to our specialist green roof substrates, Wraxalls supplies a range of green roof border materials designed to provide effective drainage, fire breaks, maintenance access, and a clean, professional finish to your roof installation.

Our 20-40mm and 40-60mm shingle, together with concrete paving slabs, are commonly used around roof perimeters, drainage outlets, roof penetrations, and maintenance routes. These materials help create defined separation zones between the vegetated areas and roof edges, ensuring compliance with design requirements while supporting the long-term performance of the green roof system.

20-40mm Shingle

A versatile aggregate commonly used as a perimeter border around extensive and biodiverse green roofs. The free-draining nature of the material helps direct water towards outlets while providing a clear separation between vegetation and roof edges.

40-60mm Shingle

A larger decorative and functional aggregate suitable for perimeter margins, fire breaks, drainage channels, and detailing around roof penetrations. The larger particle size offers excellent drainage characteristics and creates a visually distinct border around planted areas.

Concrete Paving Slabs

Concrete slabs provide durable maintenance access routes across green roof systems, allowing safe access for inspection and upkeep. They are also frequently used to create roof edge detailing, access pathways, and service routes while maintaining a neat and professional appearance.

Key Benefits
Suitable for extensive, intensive, and biodiverse green roofs
Creates clear perimeter and separation zones
Supports roof drainage and water management
Helps provide fire break detailing where required
Ideal for maintenance access routes
Durable, long-lasting materials
Available alongside our complete green roof substrate range
Delivered nationwide with coordinated logistics

Whether you're installing a small sedum roof or a large-scale biodiverse roofing scheme, Wraxalls can supply the substrates, aggregates, slabs, and associated materials required to complete your project from a single source.
