The Goals Soccer Centre in Portsmouth, one of 38 first class centres developed by Goals throughout the UK, has eight “third generation” 5-a-side and two 7-a-side pitches, constructed by Blakedown Sport & Play Ltd.

One of the most significant factors in maintaining a quality artificial playing surface is the provision of an effective drainage system, ensuring the pitch provides a consistently high quality playing performance, whatever the weather. TERRAM 1B1 Drainage Geocomposite was specified as the preferred subsurface drainage solution for this project.

At Goals’ Portsmouth facility, TERRAM 1B1 was laid over the pitches’ sub base and secured in place before being covered with a layer of “third generation” artificial grass. The superior drainage quality of TERRAM 1B1 supports a high flow rate for water as it passes through the artificial grass layer, preventing the pitches from becoming waterlogged by providing highly efficient and effective lateral drainage into the main land drainage network. In addition, the inherent strength and puncture resistance of TERRAM 1B1 makes it extremely suitable for applications that are to be subjected to significant stresses, as in this case, helping maintain the integrity of the playing surface during its lifetime.
