Moisture level is the key to a perfect arena surface, think of what it’s like to ride on the beach at low tide!

Harrison Lane Sand & Fibre Arena

The Ebb & Flow Arena System from Harrison Lane consistently maintains optimum moisture levels and surface performance through an integrated combination of:

  • Drainage pipes under the surface layer of sand and fibre.
  • A waterproof liner to contain the water.
  • A Sump/Balance Tank to pre-set and maintain the perfect water level.

The combination of drainage and irrigation creates a continuous balance of moisture underneath the arena, to best prepare the perfect riding surface.

Other benefits of an Ebb & Flow System:

  • Can be built in difficult areas as drainage is not a problem.
  • No crown or slope required in the site cut.
  • Heavy rain is not a problem as water clears quickly.
  • Uses less water than overhead irrigation as removes external factors such as the wind.

An Ebb & Flow arena base can be constructed with a sand, or sand & fibre surface, and requires access to a water source.

Choosing The Arena Base

Choosing the right base for your arena is just as important as the final surface, and there are many options to choose from! 

Sometimes options that might appear initially more expensive at the outset will actually work out more cost efficient in the long run - once all the infrastructure that is required to maintain them is taken into account. 

Having the best performing base allows a greater choice in the riding surface, and the better the riding surface the more likelihood of sound healthy horses. 

Both types of arena mentioned below should be maintained with a purpose made arena groomer to protect your investment.

Base Type – Free Draining

Subsoil drainage with layers of hardfill to allow water to drain quickly. Riding surface options are cushion ride, sand or sand and fiber mix. Irrigation is necessary on sand and fibre surfaces, and preferable on other sand surfaces.


  • Great drainage and performs very well during winter.
  • Easy to maintain 


  • Uses a lot of water and requires reasonable infrastructure for the supply of water to – pumps, power etc.
  • Dries out quickly if not irrigated

Base Type – Ebb & Flo

This type of arena is built in a watertight liner and has pipework charged with water to irrigate from below, under a layer of drainage sand. The capillary action of the sand surface absorbs the moisture required to maintain an optimum riding platform. 

Riding surface options for Ebb & Flo are sand or a sand and fibre blend.
