Post-Tension Cable, Slab and
More Repair Services

Post-tensioning is used to reinforce concrete structures. Also known as “PT”, this service involves trained professionals using advanced technologies to restore cables, slabs, and other commercial structures to their original state. The tensioning process requires for plastic sheathed steel cables to be placed before concrete is poured, and once the concrete has gained strength, the cables are pulled taut and anchored. This process increases the longevity of a commercial structure.

Post tension cables should be regularly maintained. They are vulnerable to water infiltration, which can cause rusting. If left unmonitored, the structure’s integrity could be compromised, which is one of the many reasons why it’s important that post-tensioning services are done by trained professionals.

In addition to repairs, LRT Restoration also provides post-tensioning protection and strengthening services to prolong the life of the commercial structure. The process of strengthening typically involves steel plate bonding, structural enlargement, or other processes, while protection usually involves sealers, coatings, or membrane designed to keep out corrosive material.
