When using Expanded Clay Aggregate Sustainable building practices and environmentally sound designs have become an increasingly important part of landscape design. For innovative, cost-effective, long-term solutions to modern horticulture and landscape design challenges, design professionals have turned to Expanded Clay Aggregate (ECA).
WHAT IS ECA?
Expanded Clay Aggregate lightweight, porous ceramic material produced by expanding and vitrifying select clay in a rotary kiln. The process produces a high quality ceramic aggregate that is structurally strong, durable, environmentally friendly, inert, lightweight and sound insulating. It is a non-toxic, absorptive aggregate that is dimensionally stable and will not degrade over time.
HOW CAN LECA or ECA ADD VALUE TO A LANDSCAPE DESIGN?
An ideal planting media for a rooftop garden, designing a soil for an athletic field or improving an existing soil to sustain a plant design.
DESIGN APPLICATIONS FOR ECA ROOFTOP GARDEN PLANTING MEDIA
Combining ECA with varying amounts of organic matter creates a lightweight planting media for intensive and/or extensive rooftop gardens.
With ECA, soils can be created or altered to meet design specifications or address precise project requirements. Designer soils are often required for rooftop gardens, raised planters, containers and urban tree plantings.
Incorporating ECA into heavy clay soil can provide permanent aeration and drainage within the root zone. Leca can improve the properties and qualities of existing soils to meet the requirements of the landscape design.
ECA is combined with peat, sand and other amendments to form root zone soil mixes for golf courses, athletic fields, and related turf surfaces. It is also applied as topdressing over established turf.
ECA amended soil reduces surface runoff by permitting stormwater to percolate and infiltrate
the soil surface. Rain gardens, vegetated filter strips, and turf pavers are examples of stormwater.
