• Available in both wet cast and dry cast production methods

• Custom configurations, lay lengths, and reinforcement options available to suit project-specific requirements

• Designed for municipal, highway, rail, industrial, and private development applications

3-Sided Box Culvert Solutions

For fish-friendly stream crossings, pipeline crossings, and other environmentally sensitive projects, Proform offers 3-sided box culverts as an open-bottom solution. These designs allow for:

• Natural streambeds to remain intact, promoting aquatic habitat preservation

• Fish passage and wildlife migration with no obstruction to water flow

• Easy integration with natural landscaping, reducing the need for extensive modification or additional environmental protection measures

• Ideal for crossings in environmentally sensitive areas, such as parks, nature reserves, and wildlife corridors

 

These systems provide a cost-effective, environmentally conscious alternative to traditional fully enclosed culverts, offering long-term durability with minimal disruption to the surrounding ecosystem.

​

Stormwater Management Applications

Box culvert systems are ideally suited for use in underground stormwater detention and retention structures. Proform can supply fully integrated solutions by combining:

• Box culvert sections to create large underground storage chambers

• Reinforced concrete pipe (RCP) connections for inflow/outflow

• Precast manhole risers and access hatches for inspection and maintenance

• Headwalls, flared ends, and outlet control structures as needed

 

These modular systems are ideal for stormwater management in urban developments, commercial sites, industrial yards, and roadway corridors. They maximize storage capacity while minimizing surface disruption and installation time.

​

Waterproofing & Durability Enhancements

Proform offers a range of custom waterproofing options to meet specific performance and durability requirements:

• Concrete admixtures for water repellency and enhanced longevity

• Pre-applied liners for aggressive or corrosive environments

• Waterproof wraps, coatings, and joint treatments to control seepage and protect surrounding soils

 

These enhancements help extend the service life of critical infrastructure and ensure performance in high-water table or sensitive environmental zones.

 

End Treatments & Accessories

To complete your system, Proform also manufactures:

• Headwalls and wingwalls to control erosion and provide structure at openings

• Base slabs, risers, and transitions to accommodate grade changes

• Custom fittings and junction sections for complex layouts

​​

All components are fabricated under strict quality control and built to project specifications.
