Geotextile Jacket

External filter fabric wrap for underground pipe joints
Cost effective, easy-to-install filter fabric joint wrap

MarMacʼs Geotextile Jackets stop the passage of soil and fines, preventing the undermining of pavement sub-grade material. They are cost-effective, reducing liability and the need for costly repairs.

Geotextile Jackets are designed with “simply wrap & lock” in mind. They use specially engineered, high-strength fabric that allows water to pass freely through the joint while preventing the passage of silt and soil. These geotextile fabric filter jackets are designed and manufactured for civil engineering applications and to meet DOT specifications. It is required to have a minimum of two (2) feet end overlap to assure complete coverage of the entire joint circumference. Geotextile Jackets are also available in woven and non-woven fabric often specified for subsurface drainage and filtration.

Features & Benefits
  • Resistant to plugging
  • Chemical-resistant
  • Mildew-proof
  • Cost effective
  • Permanent

Geotextile Jackets are designed and produced to the pipe size, reducing any wasted material, and eliminating the need to measure, cut, handle, or store large rolls. Their simple wrap & lock installation takes only seconds per joint. They are engineered to be permanently underground, while clamping straps ensure the product does not displace during backfill.
