Geo-Synthetics, LLC (formerly Surface Maintenance Systems) construction division was founded in 1971. The company's primary business was asphalt repair and seal coating. In 1974, services were expanded to include the installation and distribution of paving grade fabrics manufactured by a well known geotextile supplier. In 1980, an affiliate, Geo-Textile System, Inc. was formed to distribute a full line of geotextile fabrics and erosion control products.

As the geosynthetic distribution market grew in 1986, the construction division began installing geomembranes in addition to paving fabrics. The main focus of the geomembrane division is to supply, fabricate and/or install PVC, High Density Polyethylene, XR-5 and Polypropylene liners. In the geomembrane construction division we have combined experience in excess of 140,000,000 square feet of membranes.

Whether it be geotextile fabrics, erosion control, concrete accessories, building products or geomembrane installation, we have more than 120 employees in our operations to service the needs of our customers.
