When properly installed and maintained, 25 years is a conservative expectation.
Yes. This construction fabric passes 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.
Typically 6" to 8" of crushed stone.
Use crushed and angular stone that is one inch minus in size and contains 10% dust. Limestone is an excellent option, but other stone will also work.
Pins or staples can be used for convenience, but are not required to hold the fabric in place.
Yes. Overlaps should be 1'-3'.
Contractors tend to stick with products or procedure of which they are familiar. US Fabrics sells geogrids, but we do not recommend them for this application. Woven fabrics separate much better than a geogrid because they do not have the large openings of a geogrid. Woven geotextiles also offer higher strength at a lower cost. If it is our driveway, we are using US 200 every time!
Absolutely! It will increase the life of the pavement and help reduce cracking of the pavement. Place it between the subgrade and the road base material.
Driveway fabric helps prevent ruts and potholes and greatly reduces the need to replace the majority of the rock surface of your driveway every few years. It also helps prolong the life of your asphalt or cement driveway by reducing cracking.
US 200 is the fabric we recommend for the typical residential driveway application. Some unique job site or traffic conditions may require utilizing a heavier stabilization fabric. However, US 200 is a COMMERCIAL GRADE construction fabric and has high tensile strength. US Fabrics will be happy to assist you with making the proper choice for your product.
US 200 is a woven stabilization fabric. Some companies promote a nonwoven such as Typar® for driveways. A nonwoven's primary function is as a filter fabric and not a stabilizer.
Woven stabilization fabrics provide this crucial function while also allowing water to pass. Also, nonwovens have much greater elongation, meaning they stretch much more, thereby making them less appealing for driveway applications.
Furthermore, to achieve the strength equal to US 200 requires a medium to heavy weight nonwoven that will cost at least 25% more. Typar® Driveway Fabric is nearly 1/2 the strength of US 200.
The typical residential driveway fabric application is simple and straight forward.
Remove any protruding objects, such as stumps and rocks that could result in tearing or puncturing the driveway fabric. Level the surface without excavating too deeply and creating a "bathtub" effect that will hold water. If there are any areas that consistently hold water, the water will need to be removed via pipe, drain tile, or other means.
Place the stabilization fabric directly on the prepared surface. Roll it out flat in the roll direction, trying to minimize folds and creases. When required, overlaps should be 1'-3'. Pins or staples can be used for convenience, but are not required to hold the fabric in place. If necessary, a pile of stone, dirt, or other piece of material on the corners is enough to hold it in place during the dumping of the aggregate.
Place and compact the gravel in 6"-8" lifts. Dump trucks and loaders can be driven directly on the fabric if needed. However, avoid quick stops, starts and turns. The preferred method is to dump the stone onto the stabilization fabric and then push it out onto the fabric to provide some protection. Make sure to create a slight crown to your driveway to facilitate water draining to the sides.
Aggregate should be crushed, angular, 1" minus in size (diameter) with about 10% dust (or fines). Limestone is a good option, but other stone will work fine. Some names for this type of stone are "dense grade aggregate (DGA)" or "crusher run." Driveway Fabric eliminates the need to utilize stone larger than 1" in size. Avoid using rounded stone.
