Nonwoven geotextiles can also be known as drainage fabrics. They are engineered to be permeable fabrics that can separate poor soils, provide high flow, and at certain strengths even provide stabilization. Colonial can match your site with the proper nonwoven geotextile fabric in order to fix problems ranging from drainage applications, stabilization, filtration, and erosion control.
Nonwoven geotextiles are made from polypropylene fiber and have a felt-like consistency. Nonwoven geotextiles can provide a permanent barrier between stone and soil systems with an unprecedented flow capacity.
Nonwovens separate aggregate but still permit larger volumes of water to pass through the native soil into the aggregate system. These drainage fabrics can combine strength and flow capacity to eliminate the need for costly graded granular filters. Lightweight and medium weight nonwoven geotextiles are commonly used in detention and retention systems to provide cost effective on-site solutions.
Heavier weight nonwoven fabrics can also act as a soft separating geotextile layer between rough aggregate and other geosynthetic structures.The felt-like fabric provides protection for sensitive structures such as geo-membranes and liners that could be compromised if punctured, ripped or torn.
