Geosynthetics for pipe wrapping
February 1st, 2022
Q: I need impervious geosynthetics for pipe wrapping that will be placed within heavy clay. Do you have any suggestions? A: One wraps nonpolymeric pipes for many reasons. Below are some examples: Insulation (sound and thermal)Corrosion protectionWaterproofingImpact resistance Most wraps are tapes or mastics. Polyvinyl chloride (PVC), butyl rubber and bituminous wraps are common. A […]

GSI offers webinar on geosynthetics in hydraulics
January 3rd, 2018
The Geosynthetic Institute (GSI) will offer a webinar entitled “Geosynthetics in Hydraulic Applications,” on Jan. 10, 2018, from 11:30 a.m. to 1 p.m. EDT. By 2040 it is estimated that two billion people (25% of the world’s population) in 60 countries will have inadequate freshwater. This alarming prediction suggests that water must be hydraulically transferred […]
