Storm Drain/Sanitary

Our focus is not only on the products we manufacture, but also on customer service. Our in-house engineering team collaborates with you to determine the specific needs of the project to tailor a custom solution to get the job completed efficiently. Also, our quality control department ensures the completed product is of the highest quality. 

Storm Drain 

Precast concrete stormwater systems are vital to managing excessive water flow. Our products are sized to channel runoff from heavy rain to nearby bodies of water. Products made from other materials may struggle, while our precast concrete solutions excel, capable of withstanding both the volume of water flowing through them as well as external load conditions. Since precast concrete is made from natural materials, it is also environmentally friendly, making it a sustainable solution that moves water without negatively affecting water quality. 

Sanitary

We offer a diverse line of sanitary precast concrete products that are engineered for the highest quality and durability. Each product is watertight, ensuring decades of reliable service. Our sanitary products are ideally suited for a range of infrastructure applications and are available in both standard and custom configurations. 

Manholes

Precast circular vertical structures can be used for stormwater management or best-management-practice structures. Circular manholes and vertical structures can also be provided with precast invert channels.

Applications

• Changes in direction of pipe

• Changes in pipe shape

• Changes in pipe size

• Custom openings

• Custom tops

• Flexible watertight pipe-to-manhole connections

• Junctions for multiple pipes

• Observation points

• Overflow structures for ponds

• Access to the system for maintenance

• Protective linings

Specifications

• AASHTO M198 — Joints for Circular Concrete Sewer and Culvert Pipe Using Flexible Watertight Gaskets

• ASTM C1244 — Standard Test Method for Concrete Sewer Manholes by the Negative Air Pressure (Vacuum) Test

• ASTM C443 — Joints for Circular Concrete Sewer and Culvert Pipe Using Rubber Gaskets

• ASTM C478 / AASHTO M199 — Precast Reinforced Concrete Manhole Sections

• ASTM C923 — Resilient Connectors Between Reinforced Concrete Manhole Structures and Pipes

 Joints

• Confined O-ring rubber gasket

• Preformed mastic or butyl gasket

• Single offset with profile rubber gasket

Precast Junction Boxes

Used to provide service access and to achieve changes in pipe size, type, or direction. They are also useful for changes in elevation or merging two or more upstream pipes into a single larger downstream pipe.

• Handholes

• Switchgear vaults

• Telecom and transformer pads

• Tunnel and trench sections

• Rebuilt manhole replacements

Headwall and Wingwall Systems

Usually connected structurally to the adjacent conduit.

Applications

• Where appearance of the pipe end is important

• When flow must be channeled into or out of a conduit

• Where the conduit enters or exits finished grade

• When the earth embankment surrounding the pipe must be retained

• When the exposed pipe ends pose a danger to traffic

 Specifications

• Various DOTs

Reinforced Concrete Pipe 

Reinforced concrete pipe is durable, has design flexibility, and is easy to install. Our precast pipe products protect groundwater and can be manufactured in a wide range of shapes and sizes that can meet most infrastructure needs. In addition to sanitary and stormwater applications, reinforced concrete pipe can also be used for telecommunications and electrical projects. 

Applications

• Jacked or tunneled systems

• Low head pressure water transmission

• Reinforced concrete pipe is designed for culverts

• Sanitary sewers

• Storm drains

 Specifications

•  ASTM C361 - Specification for Reinforced Concrete Low-Head Pressure Pipe

• ASTM C443/AASHTO M198 — Joints for Circular Concrete Sewer and Culvert Pipe Using Rubber Gaskets

• ASTM C655 — Reinforced Concrete D-Load Culvert, Storm Drain and Sewer Pipe

 Joints

• Concrete joint with confined O-ring gasket, rubber, or neoprene

• Concrete joint with single-offset and profile gasket, rubber, or neoprene

• Steel-end rings with confined O-ring gasket, rubber, or neoprene (U.S. Bureau of Reclamation Joint Type R-2)

• Tongue and groove with mastic or butyl sealant joints are normally available for reinforced concrete pipe
