Custom Polyurethane Chemistry. Specialized Field Testing. Mechanistic Material Characterization & 3D Design. Engineered Infrastructure Solutions.

HMI and PSI Technologies are excited to announce: HMI Infrastructure. We develop custom polyurethane formulations backed by specialized testing, advanced engineering, and materials science to tackle complex infrastructure challenges.

From transportation and utilities to municipal, industrial, and structural applications, we don't just offer off-the-shelf materials. We evaluate project conditions, develop tailored polyurethane solutions, and test for measurable performance.

We're bringing this approach to IRF R2T conference, Booth #127.

🟥HMI's engineering team just got stronger🟥

We’re excited to welcome Ben to the HMI team as our newest Geotechnical Engineer.

For HMI contractors, that means even more engineering support when tackling soil improvement and specialty projects, from evaluating site conditions and developing solutions to helping with project planning and field support.

Whether you’re looking at a challenging project or want to expand the types of work you take on, our engineering team is here to help you get it done.

Welcome to Team HMI, Ben!

What do you do when you have 1,000+ cubic yards to backfill and limited access to get material in?

On this project, sidewalks, landscaping, other crews, and an occupied property made conventional aggregate difficult and labor-intensive.

The solution was HMI’s FillFoam™.

If your crews are taking on large voids, trenches, or hard-to-access backfill projects, FillFoam gives you another way to get the job done.

Just because a slab is level doesn’t mean it’s supported.

That’s where undersealing comes in. Instead of raising the concrete, the goal is to fill unsupported areas and restore support underneath.

Lifting fixes elevation. Undersealing fixes support.

See how it works and when to use it:

Undersealing is the process of introducing material beneath a slab to restore support where contact has been lost. Unlike a typical lifting project, the objective is not necessarily to change the elevation of the concrete.

Ever wonder where the foam actually goes once it’s under the slab?

Voids, loose base, joints, cracks, and other conditions below the concrete can all affect how polyurethane moves.

Watch how the foam responds—and what that response can tell you about what’s happening underground.
