Drainage

The substrate for artificial grass JUTA GRASS

Overview

JUTAgrass® can be installed on newly built bases or on existing bases such as tarmac or concrete surfaces. An elastic underlay is recommended to increase safety and the performance longevity of the playing surface. Any sub base must be stable and include some type of drainage system. In the case of an impervious base, a slight gradient must be incorporated to assist drainage. In the case of a pervious base, a lateral drainage system should be built into the sub base construction. The perimeter drainage system of a pitch must be connected either to the sewage system, soakage pit or have some means to freely drain into the ground.

New Constructions

Sports pitches are constructed with a number of different profiles (flat, sloped single plane, turtle-back, envelope, etc). Artificial turf may be installed on any of these pitch profiles. For new constructions the site should be stripped of all vegetation and topsoil and trimmed and levelled using cut and fill techniques as required to the specified profile. A well-engineered foundation is essential to the long-term integrity of a pitch. A pitch may be subjected to many different stresses such as frost heave, clay shrinkage, clay swelling and settlement. The degree to which the performance and durability of the playing surface will be affected by these forces depends on the site conditions, (e.g. climatic conditions and the type of sub-soil present and the type and depth of construction). It is therefore advisable to have a professional geotechnical survey of a site before a pitch is designed.
