Artificial grass term

What is waste factor?

Waste factor is the extra turf quantity allowed beyond measured surface area for roll width, grain direction, seams, trimming, curves, defects, and the project layout. It is not simply material thrown away.

Also called: turf waste, order allowance, cutting allowance

Roll width, grain direction, seams, curves, and trimming create necessary material beyond measured surface area.

Why it matters

Artificial turf is ordered in rolls, so a 500-square-foot yard may require more than 500 square feet of material. Two quotes can use the same site measurement but different orderable quantities.

How it is used

An estimator creates a roll layout, keeps the pile direction consistent, positions seams, accounts for obstacles, and calculates the material that must be ordered.

The money question

How can it affect project cost?

Waste directly affects turf material and sometimes infill and freight. Irregular shapes, narrow strips, many obstacles, and roll-direction constraints can increase the percentage.

Common mistakes

Applying one percentage to every layout
Ignoring roll width and pile direction
Comparing quotes without checking measured versus orderable area

Questions to ask an installer or supplier

What measured area and orderable area does the proposal use?
Can you show the roll and seam layout?
Will usable leftover material remain with me?
