It is essential that the following base criteria and installation tips and instructions are followed to ensure a proper foundation for the Groundmaster Flooring System!


  • A mechanical compactor-tamper (a roller is not recommended as it does not compact firmly enough).
  • A vibrating compactor is recommended.
  • Circular or Jig Saw, to make any necessary cuts.
  • Measuring tape
  • Hammer
  • Gloves

Like no other stall flooring, Groundmaster flooring is a soil stabilization system, NOT a rubber mat, and requires a base that has the following criteria:

Installation Tip: Many different base materials are acceptable, however, they need to be able to be compacted to set up hard, and yet be porous. The size of the last few inches should be ¼ minus, a combination of ¼ inch rock chips and dust, sometimes referred to as fines, screenings, etc.

Do Not use sand, pea gravel or plain stone as they will not stay compacted without the dust.

Note:  Each farm has a different virgin soil or previously  prepared base.  Therefore, in some cases it will not be not be necessary to use several inches of base material.  Speaking with a representative will help further assist you with any questions relating to proper base preparation and installation.





Level the original stall floor. You may have to fill in holes with some base material. If it is a new floor, be sure to wet and compact it well before starting your installation.


You will be leaving 4 to 6 inches for the installation of the floor.
Add 2 inches of the new base material, wetting and compacting firmly.
Repeat this process of laying 2 inches of base material, wetting and compacting until the acquired depth is obtained.


The next 2 inches of base. Leave this loose and un-compacted to receive the floor.
Use a straight edge, (example a 2 x 4 board) to work the last 2 inches back and forth until the base is level.


Do the following to prepare the Groundmaster floor to install:
The floors have been rolled very tight for shipment.
You should roll the floor backwards to un-curl it.

**NOTE: Floors are easier to work with when warm, but do not lay them in the sun without being covered.


Loosely roll or fold floor back up and carry in into the stall (wrapping a couple of straps around it will make it easier to carry).


Lay the floor with the funnels facing down and make any necessary cuts.
Make sure base material is damp.
Start at the back of the stall and secure the floor every two feet along the edge with anchors.
Mechanically compact the floor towards the door, anchoring and compacting as you go.
Be sure to anchor any places that do not want to lay flat; like a seam.
Put anchors one foot apart across any doorway and one on each side of any cuts.
Make sure anchor heads are level with the floor surface.

•If anchors pound in easily in the top 6 inches, then your base needs more compacting.

•Pounding anchors on a slant may help them seat in.
•Sometimes “hand tamping” is needed around the edges.


All funnels should be filled as full as possible from the bottom by mechanically compacting. Any remaining emptiness of the funnels is filled by adding a Minimum of two inches or more of the base material to the top of the floor.
Wet and compact the top base material until firmly compacted.


Six to eight inches of bedding is recommended.

Special Note

New construction or stalls repaired with large amounts of fill should be watched for closely for settling for 2 to 3 years! If the ground settles, pull anchors and re-level the base. Your Groundmaster floor will last indefinitely – if you keep it LEVEL!
