Outdoor Sports Courts
Expanded Clay Aggregate (ECA ®) or Lightweight Expanded Clay Aggregate (LECA) is used in outdoor sports surfaces like Tennis, Squash, Basketball, Rugby, Badminton, Football, Cricket and Golf Courses.
This section explains the application of EXPANDED CLAY AGGREGATE (ECA ®) in outdoor sports surface construction and the cushion effects EXPANDED CLAY AGGREGATE (ECA ®) can have on these sports surface. These surfaces includes Tennis courts, Squash courts, Basketball courts, rugby pitchec and other sports courts both in indoor and outdoors. The range of applications and gradation are widespread, it ranges from turf topdressing, to court construction for clay courts and soil amendment for sport fields.
Environmental compatibility, high permeability and total drainage capacity, makes expanded clay the optimum aggregate to realize perfect draining layers over concrete structures, sky garden and sport fields. The thickness of expanded clay protects the structure and the rain proof materials from severe thermal range, recreates an optimum habitat for green vegetation and offers a long reserve of water and air for plants and grass. Different layers of expanded clay, geotextile and natural soil may realize a good and durable cover green system
Benefits of Using Expanded Clay Aggregate (ECA ®) in construction of outdoor sports surfaces are:
- EXPANDED CLAY AGGREGATE (ECA ®) is not expensive unlike every other conventional methods
- EXPANDED CLAY AGGREGATE (ECA ®) is easy to apply
- EXPANDED CLAY AGGREGATE (ECA ®) makes the foundation porous and blocks root growth when constructing a clay court
- EXPANDED CLAY AGGREGATE (ECA ®) is not susceptible to freeze damage and this makes it ideal for foundation.
- EXPANDED CLAY AGGREGATE (ECA ®) can as well serve as a good drainage layer when applied to the foundation layer.
- EXPANDED CLAY AGGREGATE (ECA ®) is a good thermal insulator which prevents structural cracks that may result from thermal expansion or contraction.
- EXPANDED CLAY AGGREGATE (ECA ®) increases the physical and chemical activities of the root-zone (top soil).
- EXPANDED CLAY AGGREGATE (ECA ®) provides high surface area for exchanging and holding of plant nutrients.
- EXPANDED CLAY AGGREGATE (ECA ®) also contributes to aggregation of soil particles into aggregates or structural units.

- Foundation
- Regulating base
- Wearing surface
Construction Process in a Clay Court
- In constructing a clay court, the first stage is the removal of the topsoil, and this is done to get rid of the organic matter because it ROTS, which makes it unstable.
- Second stage is compacting and leveling of the ground, to give a flat surface area to build.
- After the surface has been compacted, the depth of the foundation layer depends on the type of soil formation and the local climatic conditions for example, depth of frost penetration
