Sewer & Drainage Materials

Matching the right fabric to a specific application is paramount for the success of any project. In partnership with Propex fabrics ADS provides the widest variety of woven and non-woven geotextiles in the industry to meet drainage, separation, stabilization and soil reinforcement needs.

Nonwoven Fabrics (Needle Punched)
These fabrics are designed to filter soil particles from drainage systems and stabilize roadways to increase performance life. Nonwoven fabrics are made by extruding continuous filaments of polypropylene which are then cut, opened, laid into a web, needle-punched, heat-set and rolled into the finished product. Nonwoven geotextiles are approved by many local, state and federal agencies including the Federal Highway Administration, U.S. Army Corps of Engineers, the Environmental Protection Agency and AASHTO. Nonwovens are ideal for a variety of civil engineering applications including:

• Subsurface Drainage
• Roadway Separation
• Railroad Stabilization
• Hard Armor Underlayment
• Landfill Leacheate Collection
• Underground Detention/Retention Systems

Nonwoven Fabrics (Spunbonded)
Typargeosynthetic fabric is made from a continuous polypropylene filament spun uniformly over a flat surface to make a flat, mat-like fiber. The crossed filaments are then thermally bonded together, rather than woven, into a tear-resistant material creating a filtration medium that offers excellent uniformity, puncture resistance and filtration efficiencies.

Woven Fabrics
These fabrics are manufactured from extruded polypropylene monofilaments interlaced to form a dimensionally stable construction fabric. This process produces a premium filter that is extremely resistant to soil and biological clogging. A full range of high quality filtration fabrics has been created to offer designers several choices for percent open area (POA), the single most property in the selection of a woven geotextile filter.

These types of geotextiles are used primarily for:

• Hard Armor Underlayment
• Subsurface Drainage
• Landfill Leachate Collection

Woven Slit Tape Geotextiles
These unique fabrics are made by extruding and slitting a polypropylene film, then incorporating an ISO-9002 certified manufacturing process that weaves individual flat yarns into geotextiles featuring high tensile strengths at low elongation (high tensile modulus). These characteristics allow the geotextiles to distribute loads, reduce rutting and extend the life of roads or provide substantial sediment barriers.
These types of geotextiles are used primarily for:

• Unpaved Roadways
• Paved Roadways
• Sediment Control
