Precast Bases

In instances where time-critical installations of culvert crossings are required, the “Precast Culvert Base Slab” is an ideal solution.

It is designed and manufactured to suit the Precast Concrete Portal crowns already manufactured by Aminto, and is profiled to suit the culvert.

  • Arrive on-site ready to install
  • We offer several types of precast bases
  • Manufactured to specifications 

Generally, culvert base slabs are cast with joints that are not watertight so that any excess ground water pressure (which accumulates under them) is relieved.

We provide customers with high-performance structural support for several applications. Our bases come ready for installation, reducing labour costs and job site interruptions. They are produced in a controlled environment with a strict inspection process to ensure quality for our customers, are trusted by government and municipal agencies.
