An artificial lawn installation is a practical alternative to real grass if you do not want to deal with the hassles associated with curating a lawn on a daily basis. If properly laid down, a fake grass turf can be made to look and feel exactly like a real lawn. However, laying down a perfect looking artificial lawn is a science, and you need to follow some rules to make sure it stays on. A stable base must be created to hold it in place. Here are some pointers to take into consideration for laying your artificial grass turf:
Compacted Natural Subgrade:
The bottom most layer of soil and earth must be compacted first; efficiently, in order for it to support all the layers above. You can usually and easily carry out these using a vibrating plate or a roller that you can find at your nearest equipment hire center.
Drainage Stones and Leveling Layer:
A well-balanced crushed rock base can lend support and water drainage to the sub-grade below. This layer comprises of a combination of large stones and fine materials. One of the most common materials used as the large stone element is crushed or decomposed granite, as it easily conforms to the ground’s unique surface contours. Usually the stones used here are three-eighths to three-fourths of an inch in size, and it allows the grass to keep a comparatively flatter surface.
Leveling refers to the process of flattening out the rock contours using a fine material. Filler or fine materials are used to surround the larger crushed rocks to offer enhanced turf stability. Two most commonly used materials in this domain are clay or lime composites and they can easily be filled to easily fill the gaps left by the large stones. Characteristically, these fine materials should be no larger than one-fourth inch in diameter and may be as fine as dust particles. The ideal large stone to fine material ratio to keep up in this layer is 70:30.
Backing Layer with Weep Holes:
Located between the drainage stone layer and the infill, this backing layer comes with weep holes integrated that help with water drainage during the rains down on to the leveling layer.
This layer is required to hold in place the grass fibers as well as for adding dimensional stability to the turf above. A typical need to add weight on this layer is a top-dressing or ballast.
This refers to the height of each individual blade of grass. The ideal pile height for a landscape grass lies between 1.5 to 2 inches and around 2 to 3 inches for a sports field.
Only three types of yarns are used in the manufacturing of artificial grass turf today—Polyethylene, Nylon and Polypropylene, and each of them have their individual characteristics. Polyethylene is extremely versatile and can offer an amazing balance between aesthetics, durability and softness. Nylon is porous in nature, and can be used for accommodating long blades in landscape grasses. Polypropylene yarn is typically used as a thatch layer.
