It is important that before you acquire a synthetic turf, you should be assured that the synthetic grass you select is of high quality and will continue to perform as warranted. Below are some critical guidelines you should consider before getting one;


  • Research the synthetic grass manufacturer and installation company with whom you may contract. Carefully check their service record with client references. Visit some of their installations, particularly those that are several years old and be sure to understand how customer questions, service issues, and warranty claims will be handled. Do business with companies that you believe are most likely to be in business to respond to a warranty claim throughout the warranty period.

  • Insist on a quality product that meets or exceeds your specifications and that is identified as appropriate for its intended use

  • Review all documents, including work plans, construction schedules, and contractor warranties. Make sure all agreed terms and extras are in writing;

  • Keep the synthetic grass sample you select, and compare it before installation to the product that is delivered.


Used in the tufting process to provide initial dimensional stability for the synthetic grass system, the primary backing materials are of a woven or non-woven fabric in one or more layers. GTR Turf recommends a system with a dual primary backing with a weight of at least 7 oz. per square yard.

Beside these critical guidelines, exist other specific guidelines which should be considered.

They include:

Water Permeability Rate (drainage) 

Quality guidelines

Primary Backing

Coating (aka Secondary Backing)

 

The back of synthetic grass is coated with secondary backing materials to lock the fibers in place (tuft bind). Several different coating materials are used, including Polyurethane (PU), Hot Melt Polyolefin (HMP), and Latex.

The coating should be applied with a weight and thickness configuration that depends on the design of the system and able to meet or exceed your minimum tuft bind standard.

Synthetic grass systems with infill and base materials should drain to accommodate local weather and rainfall patterns.

Permeable synthetic grass systems are typically designed to drain 25” of water per hour.

The Infill prevents the synthetic grass  installation from moving, provides an even distribution of weight to minimize expansion and contraction of turf when the temperature changes.

Among the acceptable infill materials are crumb rubber made from recycled auto or truck tires, washed silica sands that are round, sub-round or sub-angular.

Other types of acceptable infill include heat-treated acrylic coated silica sand or colored crumb rubber, TPE-coated silica sand, TPE and EPDM granules.

 

What to consider when buying synthetic turf

This term refers to the force (usually measured in pounds) required to pull a tuft from the synthetic grass backing.

The minimum tuft bind recommended is 6.8 lbs., but the higher the tuft bind, the better.

Guidelines for Infill

 

Total Yarn Weight: This refers to the weight of the yarn above the backing.

It depends on factors such as yarn length above backing (pile height) and the distance between the individual fiber tufts (density or tufting gauge). Longer pile and denser synthetic grass look more natural.

Most synthetic grass have a pile height of between 1½” and 2”, and a density of between ¼” and ½” for a total yarn weight of between 23 oz. and 80 oz. per square yard.
