Pro-Ex fibre installation guide

Firstly, why install our Horse Arena fibre additive?

  • Give your equestrian surface a new lease of life and prolong its lifespan for another 10 years.
  • Provide the sand with a root structure, this stabilises the surface to prevent the surface from riding deep and being unstable.
  • The fibres free up pore spaces within the sand allowing water to pass through far more easily which helps prevent puddling.
  • The fibres hold a relatively large amount of moisture which helps reduce summer drying.

In addition it will transform sand and rubber chip surfaces, during the installation process it drags the rubber down through with it and holds it there.

No more unstable rubber banking in the corners and no more black legs from degraded rubber chip.

It helps the rubber work where it does best which is buried within the sand giving a good flex to the surface.

Tools Required:

  • Harrow (spring tine with preferably a rear mounted roller)
  • Stone burier or rotovator (tractor mounted would save time but a hired in pedestrian machine will do the job)
  • Box grader We use a laser guided machine but a bar grader would work with a laser level
  • Rake
  • Tape measure
  • Surface dipper (a long thin screw driver works fine but be careful not to puncture the membrane)
  • Shovel
  • Note Pad and pen (outline the rectangle of your manege and mark a point every 5m)
Here is a short guide on the most effective way to install our Pro-Ex fully synthetic fibre.

Step 1

Grading your existing surface

high quality Riding surfaces from Equi-Est in the UK

The first step is to re-grade the surface that you already have, work your way around your arena kickboard and dig-out out any surface that has banked into the corners and around the outer track, throw this surface back into the Arena.

Step 2

Spreading the fibre

Now take your fibre bales and place them at equal distances apart throughout your Arena and split down the bales. The amount of bales you will need depends on various factors that when you contact us on 01594 714713 we will advise you upon, these include:

Step 3

Burying the fibre

This is the part of the process where the most care must be taken, set the depth gauge on your stone burier/rotovator at 3.5".

Now you are ready to begin burying the fibre, take great care, keep the machine at low revs and most importantly take your time.

You have to be very careful not to snag your membrane.

Work the machine up and down your arena making sure to get right into the sides and corners.

If you don't feel comfortable with a DIY install then we are happy to install it for you.

Step 4

Levelling, Harrowing and rolling

Equi-est equine manage fibre surface experts

Now you can begin re-levelling your freshly mixed surface.

Set you harrow at quite a shallow depth and begin levelling the surface, when levelling it is a kin to floating concrete, the best way is to harrow firstly in a series of small circles then larger circles,
