ASTM International geosynthetics committee developing proposed vinyl sheet piling standard
February 12th, 2021
ASTM International’s geosynthetics committee (D35) is developing a proposed standard that covers vinyl sheet piling used in marine and geotechnical fields for seawalls, retaining walls, flood walls, erosion control and pollution cutoff. According to ASTM member Steve Hargrave, innovation and engineering director at CMI Limited, the proposed standard (WK75165) will fill the need for a […]

New standard will support measuring quality of cement in geosynthetic composite mats
June 29th, 2020
A new ASTM International standard will aid engineers and specifiers looking to understand the quality and strength of cement contained in geosynthetic cementitious composite mats (GCCMs). ASTM’s geosynthetics committee developed the new standard, which is needed to allow for a consistent industry method for the application of compression strength in GCCMs. GCCMs are flexible, concrete-impregnated […]

Geocomposite lamination strength ASTM test method: Time for an update
August 1st, 2018
Recent project experience that included continuous peel testing across the roll width of geocomposite materials has shed light on the issue of peel strength between geotextiles and geonets that are heat-bonded together. The variability of peel strength across a roll width is found to be much greater than expected, with the typical standard deviation often […]
