Water Based Surface
A non-filled surface which is watered to provide a good playing experience: This is usually just used for hockey pitches. The aim is to ensure the carpet maintains its wetness during a game and this also reduces wear and maintains carpet longevity.
Water Flow Pathway
The route which water takes on a synthetic turf surface. Water will typically either, 1. Run off the surface to perimeter drains; 2. Flow down through the infill and through the nearest hole within the carpet backing material and into the base layer; 3. Flow through the infill, both vertically and horizontally in response to a compacted infill and eventually to a hole which hasn't been clogged up through any contamination and then into the base layer.
Woven Carpet
An expensive synthetic carpet which has been produced through weaving in a factory. These types of carpet might typically be used for some bowling green surfaces.
Yarn
A roll of synthetic material which is used to create a synthetic carpet. A yarn has various characteristics, including, for example:
• The type of material, which is typically polyethylene, polyamide, or polypropylene.
• The structure of the individual fibre, for example, monofilament or fibrillated.
• The shape of the fibre blade, which might be flat, or shaped in certain ways, e.g. C, V, W.
• The thickness of the material which forms the blade.
• The weight of the material. This is called Decitex (Dtex) which is the weight in decigrams per 10,000 linear metres
