Geotextiles are filter fabrics that can be installed to separate dissimilar soils and prevent the migration of materials. Geotextiles are recommended for installation at the bottom and side limits of the LID feature and should be implemented at the discretion of the engineer.

Where structural loads are anticipated or underlying soil is particularly soft, geogrid can be applied in conjunction with geotextile. Geogrid is a rigid geosynthetic material that can be laid on sub-grade to reinforce softer soils and provide a more even distribution of loads across the sub-grade materials.<br>
