Built for Every Stormwater Challenge
Storm Cross handles retention, detention, and infiltration in a single modular system — engineered for the site conditions civil engineers actually face.
Three Functions. One System.
Most stormwater projects require a combination of volume control, peak flow attenuation, and groundwater recharge. Storm Cross is the only precast concrete system designed to perform all three functions independently or simultaneously, reducing site footprint and construction cost.
Up to 100% volume retention
with sealed base configuration
Long-Term Stormwater Retention
Retention systems hold stormwater indefinitely, allowing controlled release or reuse. Storm Cross retention configurations maintain a permanent pool, making them ideal for water quality treatment, irrigation reuse, and sites with strict volume-reduction requirements.
- Municipal water quality compliance
- Irrigation reuse and harvesting
- Low-impact development (LID) credits
- Sites with zero-discharge requirements
HS-25 load rated
for traffic and parking areas
Controlled Stormwater Detention
Detention systems capture peak runoff and release it at a controlled rate, protecting downstream infrastructure from flooding. Storm Cross detention configurations are sized to meet pre-development release rates and integrate with standard outlet control structures.
- Peak flow attenuation to pre-development rates
- Downstream flood protection
- Parking lot and commercial site compliance
- Subdivision and residential development
Open-base design
for direct soil infiltration
Subsurface Stormwater Infiltration
Infiltration systems return stormwater to the groundwater table, reducing runoff volume and supporting aquifer recharge. Storm Cross infiltration configurations use open-bottom modules placed on engineered stone beds, suitable for sites with adequate soil permeability.
- Groundwater recharge and aquifer replenishment
- Runoff volume reduction credits
- Green infrastructure and LEED compliance
- Sites with high soil infiltration rates
Choosing the Right Configuration
Storm Cross modules are configured at the design stage to match site hydrology. A single project may combine retention and infiltration zones, or use detention as the primary control with infiltration overflow.
| Feature | Retention | Detention | Infiltration |
|---|---|---|---|
| Base Configuration | Sealed base | Outlet control structure | Open base on stone bed |
| Water Release | Controlled or none | Controlled rate | Percolation to soil |
| Volume Reduction | High | Moderate | High |
| Traffic Loading | HS-25 rated | HS-25 rated | HS-25 rated |
| Soil Requirement | Any | Any | Permeable soils required |
