Does your building have a broken post-tensioned cable? This is a common problem, and I can help you. 

Buildings in coastal regions are particularly prone to corrosion and deterioration that affect post-tensioned slabs. 

I regularly work with contractors or property management companies to identify and solve problems.

 For example,

(a) Evaluation of the impact of a broken strand or group of strands and the replacement work, if necessary.

(b) Evaluation of the punching shear strength of concrete slabs and repair.

(c) Rebar corrosion and concrete spalling.
