How we work

Unload it. Pack it in. Place it. Tie it.

Mats, walls, columns, decks and foundations, placed per the drawings and on your schedule. Cages tied tight, true to spec and ready to set.

Someone cored through a tendon?

We find it, fix it and restress it.

Corrosion eating a parking deck?

We pull the rusted strand, replace it and get the deck back to full strength.

Rock pockets at the anchors?

We open them up, repair the concrete and get the tendons back to full force.

New stair, elevator or atrium in an old PT deck?

We de-tension, cut, re-anchor and restress so your TI can move forward.

PT Repair & Modification

PT repair is our specialty.

Repair and modification is our specialty, not a side job. It’s the work most placers turn down, and it’s the work we’re known for.

Our crews are PTI Level 2 certified as unbonded PT ironworkers and repair specialists. We work from your structural engineer’s direction, restress to spec and hand over the records.
