Without it, fine soil particles migrate into the gravel drainage layer over time, blocking ag pipe and weep holes and causing the drainage system to fail. In reactive clay soils, this failure can happen within a few years of construction.\u003c\/p\u003e\u003ch3\u003eHow Geotextile Fabric Works\u003c\/h3\u003e\u003cp\u003eGeotextile fabric acts as a permeable filter: water passes through freely while soil particles are held back.
