As an expert in the field, I highly recommend the Aquascape Woven Microgrid Geotextile. This durable and tightly woven material is ideal for a range of applications. It provides a strong barrier against debris and rocks, ensuring that underground water reservoirs remain clean while still allowing for easy water infiltration. The pre-cut 4′ x 4′ sections are convenient and suitable for various projects, including rainwater harvesting systems, Pondless® Waterfall reservoirs, permeable pavers, and fountain basin applications. When paired with permeable pavers, this geotextile effectively maintains the base aggregate bed above the AquaBlox® or other water storage matrix.
