Post-tension problems we repair
Slab settlement
on post-tension foundations, corrected with pier systems installed with tendon locations mapped and respected
Post-tension cable repair
, including corroded, damaged, or failed tendons and blown-out anchor points at the slab edge
Slab cracking
evaluated for what it means on a tensioned system, which differs from conventional slabs
Moisture and leak-related damage
, coordinated with hydrostatic testing when an under-slab plumbing leak is suspected
Why post-tension repair is its own discipline
A post-tension slab is a system under load. Repairs begin by locating tendons, understanding the original design intent, and planning pier placement and any penetration around them. Engineering oversight runs through our scoping and sign-off, and a licensed Professional Engineer co-owns the company, which is the right backdrop for a repair category where guesswork is genuinely hazardous.
The inspection includes mapped elevation readings across the slab and notated findings, so the recommendation is built on data. Sometimes that recommendation is monitoring rather than repair. When work is recommended, you receive a written quote within one business day, financing is available, and work carries a transferable workmanship warranty, terms vary by service.
Cardinal performs this work across the Dallas-Fort Worth Metroplex and the Houston area.
Frequently asked questions
Homes commonly have a stamped notice at the garage slab edge or in documents warning against cutting or drilling the slab. Age and builder are clues; verification is part of our inspection.
Not automatically. Hairline shrinkage cracks are common; wider, offset, or growing cracks warrant evaluation. On a tensioned slab, the assessment considers the system, not just the crack.
Yes. Pier systems work under post-tension slabs when placement is planned around the tendons and load points, which is exactly how we scope them.
Corrosion over time, construction-era defects, and slab-edge deterioration are the usual causes. Repairs restore the tendon or anchor and address what let it fail.
