Advanced Structural Performance for Greater Long-Term Reliability

StormTech developed a state of the art chamber design:

• Collaboration with world-renowned experts of buried drainage structures to develop and evaluate the structural testing program and product design.
• In Europe our chamber products have achieved approvals that comply with rigorous BBA and CSTB Standards for Underground Chamber Systems.
• Designing chambers to exceed American Association of State Highway and Transportation Officials (AASHTO) LRFD design specifications for HS-20 live loads and deep burial earth loads
• Subjecting the chambers to rigorous full scale testing, under severe loading conditions to verify the AASHTO safety factors for live load and deep burial applications
• Designed to conform to the worldwide product requirements of ASTM F2418 (polypropylene chambers) and design requirements of ASTM F2787 ensuring both the assurance of product quality and safe structural design.
