  • This is a special adaption of the Type 2 barrier. Approximately 20% or more of the area of the barrier skirt fabric is replaced with a polypropylene filter fabric conforming to some State DOT specifications. The filter fabric is inserted to reduce the pressure on the curtain while retaining silt.
  • It is highly recommended that you contact a qualified engineer for assistance when facing these conditions because the anchorage and installation must be designed exactly to meet these situations

Why Buy Turbidity Curtains from Paramount Materials?

  • We only sell the Tough Guy brand commercial-grade curtains which are made in the USA. Widely regarded as the “go to brand” for quality and strict adherence to stated specifications.
  • We do not sell "no-name" or "off-brand" curtains. These economy curtains often claim to meet spec but due to oversees manufacturing variances sometimes do not, leaving the installer exposed to potential fines and project delays.
  • When you call, we answer. When you call Paramount Materials you get a live person quickly, ready to help with product or order questions. (M-F 5:00 am - 3:00 pm Pacific Time)
