RETENTION SYSTEM | GREEN STORMWATER INFRASTRUCTURE
TDR STORM-BREAKER
Our green stormwater infrastructure is designed to be a strong and reliable underground retention system, specifically designed to prevent unusual and hazardous stormwater runoff. The engineering of this system allows for rainwater storage, catering to various non-potable uses, such as irrigation, cleaning, or equipment cooling in the industry. A system that every project must consider for the care and intelligent use of water.

TDR™ ULTRA WT pipe shall have a dual-wall structure – with a corrugated exterior featuring reinforced double-arch corrugations and a smooth black liner for the interior. Additionally, it will include a dual-layer co-extruded integrated bell. The Manning’s “n” value for use in design shall be 0.010.
• 4- through 10- inch meet AASHTO M252, ASTM F2648 and ASTM F667
• 12- through 60- inch meet AASHTO M294, ASTM F2306, ASTM F2648 and ASTM F667.
JOINTS
For closed watertight systems:
TDR™ ULTRA pipe shall be joined using a watertight dual wall integrated bell and spigot joint meeting the requirements of AASHTO M252, AASHTO M294, ASTM F23O6 and ASTM F2648. The joint shall be watertight according to ASTM 3212.
Pre-installed gaskets shall meet the requirements of ASTM F477. A joint lubricant provided by TDR™ or any other water-based lubricant shall be used during the joint assembly. Please refer to TDR™ lnstallation Guideline far more details.
