Abstract (en)

A ground water drainage network is formed from interlocked strips (10) reinforced with high tensile fibre bundles (12) embedded in the strip. The centre of the strip has a plurality of channels (111) and a drainage filter sheet (13) is connected and covers the top of the strip. The arrangement provides an efficient means for rain water and underground water to be drained from a construction site to increase ground stability and prevent earth movements. <IMAGE>
