Abstract
An area suitable for sporting activities comprises an upper synthetic surface layer, and a sub-surface support layer which includes a load bearing structural module. The structural module comprises a top wall and a bottom wall spaced therefrom by one or more supporting elements so as to define a volume between the top and bottom walls. The top wall is provided with a plurality of apertures to permit the flow of liquid into and out of the volume. The size and shape of the apertures is such that the apertures cause substantially no variation in the flatness of the synthetic surface layer.
