Can I use a woven construction fabric for stabilization & separation instead of a geogrid?
In most cases, the answer is yes. In addition to superior strength and lower cost, woven geotextiles (construction fabrics) offer an added advantage over any geogrid: separation. Geogrids rely on "interlock," a process whereby the soil particles or aggregate "lock" into place within the geogrid's open structure or apertures. Often, the actual particle size is not known and/or varies widely, so the amount of interlock provided can be in question. In fact, geogrids often require the use of geotextile as part of a separation/stabilization system.
Why use a woven instead of a nonwoven geotextile for stabilization & separation?
Woven geotextiles are less expensive than non-woven geotextiles; are also permeable (allow water to pass); and do not elongate (stretch) like nonwovens. In most applications, a woven geotextile is the more effective and economical option.
Will these construction fabrics pass water?
Yes. These construction fabrics pass between 4-5 gallons per minute per square foot in laboratory testing. The permeability of the soil is the bigger issue. A fabric will not make a soil drain. If standing water is an issue, re-grading the area, and/or installing a drain tile or culvert should be considered to remove the problem water from the area.
How long will this geotextile last?
100% polypropylene geotextiles are inert to just about everything. The biggest threat to a geotextile is ultraviolet radiation. Once covered, the UV is no longer a concern. Studies have shown that polypropylene geotextiles can last in excess of 25 years in stable soils.
Do your woven stabilization & separation products meet the AASHTO M-288 specification?
Yes. US 200 meets AASHTO M-288-15 Class 3 Stabilization & Separation; US 250 meets AASHTO M-288-15 Class 2 Stabilization & Separation; US 315 meets AASHTO M-288-15 Class 1 Stabilization & Separation.
Are your woven stabilization & separation products NTPEP compliant?
Yes. You will find the NTPEP GTX numbers on the data sheets for our stabilization & separation geotextiles that have been approved by NTPEP.
I am trying to meet a project specification, can you help?
