Drainage 20mm
Aggregate drainage scoria, distinguished by its particle size of 20mm is a variant of volcanic rock frequently harnessed in a broad spectrum of construction and landscaping scenarios due to its exceptional attributes. Its porous structure is particularly suitable for drainage, particularly in French drains and subsurface drainage systems. This permeable nature enables the efficient passage of water while mitigating the risk of soil obstruction or clogging.
This is a natural product, and colour variations may occur between batches. We recommend taking delivery of the full job requirements at once to minimise colour differences.
Applications
Scoria proves highly valuable in constructing permeable pavement systems, facilitating water infiltration through the surface and into the ground. Incorporating a layer of 20mm scoria beneath the pavement aids in the management of stormwater runoff and minimises surface water accumulation.
Retaining Wall Drainage: Particularly in the construction of retaining walls responsible for retaining soil or water, the utilisation of 20mm scoria as a drainage layer behind the wall effectively manages water drainage and mitigates hydrostatic pressure, which could otherwise jeopardise the wall’s stability.
Landscaping and Gardens: In landscaping endeavours, 20mm scoria is a favoured choice, serving diverse roles such as crafting decorative pathways, dry riverbeds, or mulching material. Its distinctive appearance and permeability make it a popular selection for elevating the aesthetics of outdoor spaces.
Erosion Control: Scoria’s application extends to stabilising slopes, embankments, and waterways. Its porous structure acts as a barrier against soil erosion and provides resilience against water flow forces.
Drainage Swales: Drainage swales, strategically designed to channel and manage stormwater runoff, can benefit from incorporating 20mm scoria in their base, facilitating efficient drainage pathways.
Backfilling and Trenches: When backfilling trenches for utility installations, introducing a layer of 20mm scoria surrounding pipes or conduits ensures proper drainage and inhibits soil compaction.
Green Roofs: In green roof systems, 20mm scoria can be used as a lightweight drainage layer beneath the growing medium. This facilitates water drainage and safeguards against waterlogging of the roof substrate.
Rain Gardens: Scoria is pivotal in constructing rain gardens, effectively managing stormwater runoff and facilitating groundwater infiltration.
Benefits
The application of 20mm scoria in drainage systems varies according to project specifications, local regulations, soil conditions, and engineering prerequisites. Achieving an effective drainage system hinges on meticulous installation techniques that account for factors such as water flow, compaction, and stability. It is advisable to seek guidance from experienced professionals well-versed in drainage system design and construction to ensure the successful execution of such projects.
