Granule Size: Approx. 4-8mm.

Density: Harena is a lightweight aggregate with a bulk density at point of supply of approximately 850kg/m³. ie volume for volume Harena Sports Drainage Media is half the weight of "normal" limestone or gravel aggregates.

Moisture Content: As supplied 4-8mm Harena Sports Drainage Media is likely to contain a natural moisture content of up to 15%.

Description & Application:
Harena Sports Drainage Media is a brick-like lightweight aggregate that is frost resistant and will not break down when saturated with water. The product typically contains less than 1% passing 2mm size making it an idea drainage medium.

Harena Sports Drainage Media provides excellent hydraulic conductivity making it the professionals' product of choice for slit trenches, gravel banding and for use with Shelton Trenchers. The product is used for both the construction and retro-fitting of drainage on golf courses.

Herana also finds application for other sporting surfaces including granular backfill to open trenching and turf slitting.

Benefits of Harena Sports Drainage Media

Stability: Harena does not degrade, clog or impede drainage, providing excellent performance and long life to drainage schemes.

Ease of Placing: Being a rounded aggregate, Harena can be poured direct from the bag potentially reducing the need for specialist placing equipment.

Use in soft ground: In wet and difficult ground conditions packed Harena can be used when it would be difficult to transport heavier natural aggregates.

Particle Shape: The rounded particle shape prevents damage to plastic pipes and membranes.

Non Compactable: Irregular shaped natural aggregates compact and silt up over time. Harena's rounded shape maximises voids for efficient land drainage and aeration.

High Drainage Volume: Non compactability and high hydraulic conductivity provide for high drainage volumes. Typically a soakaway system using Harena Sports Drainage Media can retain up to one third of its weight in water.
Harena can absorb and retain up to 20% of its weight in moisture, helping to reduce drought stress in hot, dry weather.

Easy on "Man and Machinery" : Rounded shape and low density reduce damage to handling machinery
Due to Harena Sports Drainage Media being half the weight of natural drainage aggregates, handling is less arduous and the risk of physical injury is reduced.

Source
Harena is made by sintering pelletising selected clays in a rotary kiln. As they are fired, the pellets fuse to create a brick-like structure whilst moisture in the pellets expands to produce a microporous core. The resulting granules are lightweight, porous, and have a high resistance to crushing.

Environmental Considerations:
As Argex is approximately 50% the weight of "normal" aggregate, twice the volume can be carried, reducing vehicle movements both on and off highway.
For a given volume, bound Argex Concretes and screeds use less cement, therefore providing a significant energy saving.
