Sand and Infill

Of all of the elements of the artificial grass install, few are as important or as misunderstood as the application of infill.

The infill is the final “part” to be attached to the installation. In most instances it is silica sand poured onto and sifted into the blades of the turf.

The silica sand used is more “pure” than run-of-the-mill sand purchased at the hardware store for your kid’s sandbox or of the type used in the production of concrete. Silica sand granules are close to being perfectly round and easier (more likely) to be sifted to the bottom of the blades and onto the base of the turf.

The application of sand does two things:

  • It holds the turf in position.
  • Makes the individual blades of grass stand upright.

By weighing down the turf, this allows the glue to take hold and supplements the holding power of the stakes driven into the turf.  The whole package keeps the turf from shifting and allows it to feel firm as the real grass it replaces.

Raking in the sand makes it sink to the bottom of the installation.  Hundreds of pounds of sand are used on each installation.

Making the blades of grass stand up not only makes the close-up appearance look real, it also makes the “step-back” look of the turf look real.  You have to see it to appreciate it.
