Geotextiles & Geogrids

Geotextiles & Geogrids help you control erosion, stabilize soil, improve drainage, and reinforce bases across construction, roadwork, and landscaping. By separating weak subgrade from aggregate, distributing loads, and managing groundwater, these geosynthetics reduce rutting, minimize settlement, and extend the service life of driveways, parking lots, trails, and pavements. They also keep riprap in place along shorelines, protect slopes, and strengthen retaining walls.

Choose woven geotextile fabric for high tensile strength and separation under road bases and driveways; it limits aggregate loss and cuts maintenance. Use nonwoven geotextile fabric where filtration and drainage matter, such as French drains, under riprap, behind retaining walls, and around culverts; it allows water to pass while trapping fines. Select geogrids to reinforce soil and aggregate: uniaxial geogrid for retaining walls and slope stability, and biaxial or triaxial geogrid for base stabilization and improved load distribution under pavements.

Key specs to compare include tensile strength (lbs/ft or kN/m), aperture size for aggregate interlock, permeability for drainage, puncture resistance, UV stability, roll width/length, and fabric weight (oz/yd² or gsm). Common polymers are polypropylene, polyester, and HDPE, chosen for durability and chemical resistance.

Quick installation tips:
- Strip organics, smooth and compact the subgrade.
- Overlap geotextile seams 12–24 inches and stake or staple as needed.
- Orient geogrid in the required strength direction; tension flat with minimal wrinkles.
- Place clean, angular aggregate; build in proper lift thickness and compact each lift.
- Cover promptly to limit UV exposure and prevent damage.

Shop geotextile fabric, driveway fabric, drainage fabric, erosion control fabric, uniaxial geogrid, biaxial geogrid, and retaining wall grid. Look for AASHTO/NTPEP-compliant products to meet spec. Using the right geosynthetics can lower aggregate requirements, speed construction, and deliver longer-lasting, lower-maintenance surfaces and structures.
