To ensure that the artificial grass is long-lasting and safe enough for all kinds of activities, it is common for turf to come with more than the exterior layer of green. This is especially true if the area in which the synthetic lawn is going to rest on is not even or poorly maintained. This is when the optional padding layer comes into handy. This underneath compartment will provide a more stable and comfortable support for the extensive groundwork which comes after.
The most common type of padding will be the pressure cloth. It is usually the cushion layer between artificial grass and the ground. The ground should be evenly sanded before rolling over with the pressure cloth. The cloth should be as close to all edges of the area as possible, so as to keep out from dust, dirt, or growing of weed. The main aim of this layer it to ensure pressure from the artificial grass layer is equally distributed within the area so that it will appear flat and smooth for usage.
Some padding layers will ensure safer practice as compared to others. For example, additional care and fulfillment of safety requirements will need to be exercised while preparing the grounds for children and athletes. In these incidences, foam of various density will need to be considered on top of the pressure layer. Light density foam is employed commonly for the use of children’s playgrounds. Light refers to its weight and it tends to be about four to seven pounds per cubic foot to withstand the continuous pressure coming from constant activities.
The medium density foam will be about eight to ten pounds per cubic foot and it aimed to replace the discomfort brought about by uneven floor or crushed stones in which the synthetic lawn is going to cover. The high density foam will weigh about 11 to 13 pounds per cubic foot, regularly used to sustain the impact coming from sport field applications.
A good padding should be able to meet the critical fall heights of up to three metres. In schools or children’s playgrounds, there is also a need to ensure that the turf is able to meet the Head Injury Criterion (HIC) set up as part of the safety regulations. If the synthetic lawn is intended to be used by athletes, the padding will have to be as air-cushioned as possible so as to endure the large impact coming from intensive practices while enabling sportsmen to improve their fitness.
