Aquascape Woven Microgrid Geotextile is a durable woven geotextile material ideal for use in a variety of applications. The material provides a long-lasting barrier to prevent rock and debris from entering sub-surface water reservoirs while allowing water to easily infiltrate the storage basin. The convenient 4' by 4' pre-cut sections are perfect for most project applications, including rainwater harvesting systems, Pondless® Waterfall reservoirs, permeable pavers, and fountain basin applications (or purchase by the roll). In permeable paver applications, the geotextile will effectively keep the base aggregate bed on top of the AquaBlox® or other water storage matrix.
