StormTech

StormTech has thousands of chamber systems in service throughout the world. All StormTech chambers are designed to meet the most stringent industry performance standards for superior structural integrity.

 

The StormTech system is designed primarily to be used under parking lots, roadways and heavy earth loads saving valuable land and protecting water resources for commercial and municipal applications. In our continuing desire to answer designers’ challenges, StormTech has expanded the family of products providing engineers, developers, regulators and contractors with additional site specifice flexibility.

Features
underground structural water storage system for rainwater harvesting, stormwater detention and infiltration

StormTech arches are well suited to under highways, roads, car parks and other trafficable or non-trafficable applications. They utilise the strength of stone and the multi radius arch shape to create a reliable subsurface stormwater management system.

 

The advanced design of the StormTech chamber allows stormwater professionals to implement more profitable and environmentally sustainable water storage.

 

Innovative StormTech chambers offer lower installed costs, superior design flexibility and enhanced long-term performance compared to other structurally designed subsurface stormwater management systems.

 

StormTech chambers are ideal for commercial, municipal and residential applications. One of the key advantages of the StormTech chamber system is design flexibility. StormTech arches can be configured into beds or trenches or in a centralised or decentralised layout.

Stormtech chambers are backfilled with clean aggregate and depending on the application then wrapped in geotextile.

StormTech developed a state of the art chamber design through:

  • Collaboration with world-renowned experts of buried drainage structures to develop and evaluate the structural testing program and product design
  • 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
  • Designing chambers to conform to the product requirements of ASTM F2418 and ASTM F2922 and design requirements of ASTM F2787 ensuring both the assurance of product quality and safe structural design
more features
  • Large capacity that fits very tight footprints providing developers with more usable land for development
  • A proven attenuation alternative to cumbersome large diameter metal pipe or snap together plastic crates and unreliable multi-layer systems
  • Provides the strength of concrete vaults at a very competitive price
  • The robust continuous true elliptical arch design, which effectively transfers loads to the surrounding backfill providing the long-term safety factors required by AASHTO. Offers developers a cost-effective underground system that will perform as designed for decades.
  • Designed in accordance with the AASHTO LRFD Bridge Design Specifications providing engineers with a structural performance standard for live and long-term dead loads • Polypropylene and polyethylene resins tested using ASTM standards to ensure long and short-term structural properties
 
  • Injection molded for uniform wall thickness and repeatable quality
  • Third-party tested and patented Isolator Row for less frequent maintenance, water quality and long-term performance
  • Incorporates traditional manifold/header designs using conventional hydraulic equations that can easily verify flow equalization and scour velocity
  • Open chamber design requiring only one chamber model to construct each row assuring ease of construction and no repeating end walls to obstruct access or flow.

STORMTECH SC-160LP CHAMBER

Designed to meet the most stringent industry performance standards for superior structural integrity while providing designers with a cost-effective method to save valuable land and protect water resources. The StormTech system is designed primarily to be used under parking lots thus maximizing land usage for commercial and municipal activities.

The SC-160LP chamber was developed for infiltration and detention in shallow cover applications

  • Only 14” (350 mm) required from top of chamber to bottom of pavement
  • Only 12” (300 mm) tall
  • Installs toe to toe – no additional spacing between rows

STORMTECH SC-310-3 CHAMBER

The proven strength and durability of the SC-310-3 Chamber allows for a design option for sites where limited cover, limited space, high water table and escalated aggregate cost are a factor. The SC-310-3 has a minimum cover requirement of 16” (400 mm) to bottom of pavement and reduces the spacing requirement between chambers by 50% to 3” (76 mm). This provides a reduced footprint overall, reduces aggregate needed, and allows the designer to offer a traffic bearing application yet comply with water table separation regulations.
