When to Choose Standard vs Custom Precast

Standard Precast

• Cost-effective

• Readily available

• Requires your design to match existing dimensions and configurations

Custom Precast

• Fully tailored to project-specific needs

• Allows unique sizing, openings, and configurations

• Higher cost and longer lead times

Modified Standard (The Middle Ground)

• Standard products with minor modifications

• Reduces cost and lead time

• Can be specified early in design or adapted in the field

Jensen Infrastructure has been designing and manufacturing precast solutions since 1968. With a team of in-house engineers and decades of project experience, we help you determine whether a standard, modified, or custom solution is right for your application.

We offer modular components—typically round, square, or rectangular—available in 1′ height increments and riser sections in 6″, 12″, 3″, or 24″ sizes. These allow for efficient design flexibility with reduced lead times.

Utility Boxes

• Available in standard, modified, or custom forms

• Approved products for most local agencies and utilities

• Applications: vaults, pull boxes, handholes, and equipment pads (dry utilities), as well as manholes, catch basins, drainage inlets, pipe, and tanks (wet utilities)

Design Considerations

• Sizes & load ratings

• Pipe/conduit openings

• Access & vents

• Sumps, sealants, coatings, and liners

• Concrete & reinforcement specs
