The average life of a pitch is 10 years, based on normal quality, proper installation, reasonable maintenance, exposure to sunlight and normal usage over its lifetime.
A typical 3G pitch contains a combination of turf backing (5% rubber and thermoplastic polymers), turf fibres (5% polyethylene and other plastics), infill (60% sand and 30% crumbed/granulated rubber).
The infill material represents 90% of the volume however a full size pitch will contain plastics the equivalent of more than 23m supermarket plastic bags.
Some pitch installations will include base support (e-layer) that either improves playability or drainage. These products can be used for multiple pitch life cycles.
A typical synthetic turf pitch weighs approx 220-240 tons and covers 7,000m2.
Granulated car tire product SBR (Styrene Butadiene Rubber) has been the preferred infill component, along with sand, however, over recent time the usage of other rubber fractions has increased.
Once a new pitch is installed, it will within its first 3-4 months require a top-up of rubber granulate; 10-12 tons; and each year thereafter, normal maintenance will require 4-5 tons of rubber granulate for top-up.
Today, in Germany, 80% of the pitches being installed contain EPDM (Ethylene Propylene Diene Monomer) and TPE (Thermo Plastic Elastomer) rubber infill. These products have proven durability in all types of climates and will not change properties under high temperatures, while being available in any colour.
