Post-tensioning Home / MODIFICATIONS - REPAIRS - STRENGTHENING

Modifications:

It is many times required that modification has to be considered should any changes arise in building use or to the building codes. These modifications could involve cutting openings, such as those for stairs, elevators, and escalators, without generating any problem to existing structure.
NAMCONG has succeeded in researching and applying openings cutting solution and also been awarded the Intellectual Property Certificate for Neo Zip system, which is a valuable contribution to post-tensioned slab modification techniques.

Cutting holes and openings in post-tensioned slabs requires specific method conducted by our experienced personnel with specialized equipments. This process involves locating tendons, excavating concrete around tendons, detensioning and cutting the tendons, and re-anchoring them at the edge of the new opening.

 Repairs:

This method is indeed essential for any projects that are deteriorated, expires its service life but requires upgrading or encounters any unexpected faults. This repair process involves in the repair and replacement of damaged tendons, which is preceded by a thorough investigation to the cause.

Strengthening:

In various cases of changing loading, usage modification, incorrect construction practices, structure damage or even error in design process.
Post-tensioning system shall offer an optimal and economical solution for strengthening considered structure. A deep consideration shall be taken on every details such as tendons profiles, supports, anchorages, in order to implement strengthening in beam, floors or even removing columns.

External post-tensioning can be used for new structures as well as for existing structures needing strengthening. This technique has been used for various types of structures with reasonable compression characteristics.

Particularly, this technique shall be a priority solution to be considered in cases of substandard concrete, badly cracked concrete structure or any unexpected faults.

For this technique, the tendons are not installed inside the cross-section structure, the anchor system is installed externally. After completion of construction, the anchor and tendon are covered with epoxy painting or grouting for further protection.
