Geo Strap Strain
October 1st, 2024
Q: We are using a 40kN polyester-coated strap for mechanically stabilized wall reinforcement. We sent the strap to a third-party laboratory for quality assurance testing, and they reported an ultimate tensile strength of 20kN (half of the project specification) and a strain at rupture of greater than 50%. Can you offer a suggestion on how […]
Geomembrane Thermal Expansion and Contraction
October 1st, 2024
Q: We are installing geomembrane in extreme weather conditions. We’ve been talking to a client who has a high thermal gradient where temperatures vary in the same day from 55°C to 0°C. He’s been asking us about the thermal expansion and contraction that the geomembrane can present on the field. Is there a number he […]
Critical Geosynthetics Interface
October 1st, 2024
Q: I have a question regarding critical geosynthetics interface for a final cover system. The cross section from top to bottom is as follows: 18-inch cover soil Drainage geocomposite made up of a geonet thermally bonded to NPNW geotextiles on either side Double-sided textured geomembrane 500 g/m2 NPNW geotextile gas vent Soil MSW waste I […]
PVC pipe leak repair
October 1st, 2024
Q: Can buried PVC plastic pipe be repaired? Our pipe has been impacted after being buried for seven years and we are seeing a bit of moisture on the outside of our pressure pipe. A: Resin cloths, patches, saddles and tapes are quick and simple options for repairing PVC pipe leaks. Unfortunately, they are temporary […]
Surface Impoundment Leak Detection
October 1st, 2024
Q: We have a double composite surface impoundment with a leak detection between the liner system containing frackwater (brine with high chlorides content) and are seeing evidence of a leak in the primary liner after five years of excellent operations. The pond and leak detection zone (LDZ) levels have been stable for years, but after […]
