Artificial Grass Shopper

Artificial grass term

What is perforated backing?

Perforated backing is artificial-turf backing made with regularly spaced holes that allow water to pass through at those points. Hole size and spacing vary by product, and the complete installation determines real-world drainage.

Also called: hole-punched backing, punched backing, perforated turf

Water passing through regularly spaced holes in an otherwise solid artificial-turf backing.
Perforated backing drains at its holes; spacing and the complete installation shape real-world performance.

Why it matters

Perforated products are common in landscape installations, but they require a compatible base and positive drainage. Product-level flow claims should not be mistaken for a guarantee about the yard.

How it is used

The perforations are positioned during manufacturing. Installers must keep the supporting assembly permeable and avoid creating trapped low points below the surface.

The money question

How can it affect project cost?

Perforated backing is common and does not create a predictable premium or discount. Site drainage corrections, base preparation, and product quality can affect cost more significantly.

Common mistakes

  • Assuming visible holes solve existing standing water
  • Blocking flow with an unsuitable base or installation layer
  • Failing to compare hole spacing and test documentation

Questions to ask an installer or supplier

  • What is the tested drainage rate and under what conditions?
  • Is perforated backing suitable for my pet or rainfall conditions?
  • Where does water discharge after reaching the base?
