Drainage materials

Geosynthetics Specifier’s Guide

Geonets, sheet drains, edge drains, and prefabricated vertical drains are all designed to offer strong, performance-enhancing alternatives to traditional drainage systems.

Geocomposite drainage systems are engineered to minimize costly, conventional graded-aggregate and/or perforated-pipe subsurface drainage systems. Geonets, sheet drains, pavement edge drains and prefabricated vertical drains (PVDs) have reached acceptance as state-of-the-practice because they provide sufficient in-place drainage and offer reduced material cost, installation time, and design complexity over traditional systems.

The selection and design criteria for this category of products are generally simple. However, because of the numerous applications for subsurface drainage systems and varying performance parameters, designers must pay careful attention to the product-performance parameters applicable to a particular subsurface drainage application.

  Re: Cost

  Please see listings related to geogrids in the annual Specifier’s Guide produced by Geosynthetics magazine. Companies that produce these materials can give you an estimate of cost.
