Lavia Ekstensive
Growing medium for extensive green roofs, rain gardens and rock gardens – Lavia Ekstensive is a lightweight mineral-organic growing medium designed for plants with modest growing requirements. Its low weight, high permeability and moderate water-holding capacity reduce the need for intensive maintenance.
It is used primarily in shallow extensive green roof systems and in projects where low structural loads and straightforward maintenance are essential. It is ideal for plants tolerant of periodic dry conditions, such as sedums, mosses and other ground-cover plants.
Composition:
Growing-medium composition:
Volcanic tuff – a lightweight, porous mineral material that increases air-filled porosity and structural stability
Fine basalt aggregate up to 1 mm – provides effective drainage and helps prevent compaction of the growing medium
Fen peat – improves water retention and increases the blend’s sorption capacity
Key benefits:
- ready to use – no additives or mixing required
- one substrate for many applications – lower costs and simpler logistics
- safe for plants and the environment
- stable, lightweight and made from high-quality materials
Application:
- green roofs – extensive systems
- rain gardens and infiltration zones
- rock gardens and gravel gardens
- plants in large planters and containers
- green tram tracks
Lavia Intensive
Growing medium for intensive green roofs, roof gardens and landscaped areas over structural slabs –
Lavia Intensive is a specialist growing medium with a higher nutrient content and water-holding capacity, creating conditions similar to natural soil. Its carefully designed structure provides stability, water retention and an optimum environment for more demanding plants.
It is used in landscaping projects involving more elaborate planting schemes on intensive green roofs and terraces, in landscaped areas over structural slabs and in urban spaces. It can be used to establish lawns, herbaceous perennial beds, shrub and tree planting, and complete roof gardens.
Composition:
Growing-medium composition:
Volcanic tuff – a lightweight, porous mineral material that increases air-filled porosity and structural stability
Fine crushed and washed aggregate (basalt or quartz) – provides effective drainage and helps prevent compaction of the growing medium
Fen peat – improves water retention and increases the blend’s sorption capacity
Key benefits:
- ready to use – no additives or mixing required
- one substrate for many applications – lower costs and simpler logistics
- safe for plants and the environment
- stable, lightweight and made from high-quality materials
Application:
- lawns and meadows
- perennials, bulbs and ground-cover plants
- ornamental shrubs and trees
- plants in large planters and containers

Lavia Substrates
Working with us
From landscape concept to substrate delivery
You do not need to know from the outset which substrate variant is right. Describe the project type, planned planting and location, and we will help select the appropriate Lavia variant and agree the delivery method.
-
01
Describe your project
During the initial contact, we establish whether the substrate will be used on a green roof, in a rain garden, in planters or containers, over a structural slab, or in another landscaped area.
-
02
We select the Lavia variant
Based on the type of planting and nature of the project, we help select Lavia Ekstensive or Lavia Intensive.
-
03
We agree the quantity and form of supply
Depending on the scale of the project, we select the appropriate delivery format: in bulk, in 1 m³ bulk bags or in 15-litre bags.
-
04
We arrange order fulfilment
Once the details are agreed, we prepare a quotation and discuss collection arrangements or delivery to the project site.

How does an extensive substrate differ from an intensive substrate?
An extensive substrate is a lightweight growing medium applied in a shallow layer and intended for low-maintenance planting. It combines low weight and good permeability with a lower organic content, making it suitable for systems where low structural loads and minimal maintenance input are important.
An intensive substrate has a more complex structure and a higher organic matter content, supporting more demanding plants. It is used in projects where the growing medium functions in a similar way to natural soil, providing appropriate water retention, nutrient availability and stability for larger, more demanding plantings.
