By bradlelfJune 15, in Civil Engineering. The joint is made up of concrete surfaces, with a compression type rubber gasket.
These joints are normally used in sanitary sewers to hold infiltration and exfiltration to a practical minimum and are adequate for hydrostatic heads up to 30′. The joint is made up of concrete surfaces with a groove on the spigot for an O-ring rubber gasket also c443 to as a confined O-ring type joint.
These joints are normally used in gravity sewers where exceptional tightness is required. This type of joint provides excellent inherent water tightness in both the straight and deflected position and meets all the joint requirements of ASTM C Yeah, I am familiar with the standards’ just didnt know if anyone had ever spec’d on SWM facility outfalls.
I get into an argument with contractors on almost every project because they fail to read the plans and specifications. Always want to “value engineer” something as adtm as the gaskets that are called for.
ASTM C443 – 12(2017)
Not sure what to tell you. I’ve never seen anything used at joints for storm drain pipe other than Class C mortar. It seems to me that ASTM C might be more appropriate for storm asgm pipe decent water-tightness, supports full pipe flow and ASTM C might be more appropriate for sewer pipe superior water-tightness, more suitable for partial-full gravity flow?
