In Denver Colorado, Nehemiah Rebar Rod Busters are at work installing Post Tensioning Cables at Sloan's Lake. Post Tensioning is a technique used to reinforce concrete. Rebar Post Tension cables are placed into forms before concrete is poured, once the concrete has set, the cables are pulled tight and anchored against the outside edge of the concrete.
Post Tensioning provides "presstressing", which means the steel reinforcing is stressed before the concrete has to support the loads. The advantages of using post tensioning techniques are many -including; reducing or eliminating shrinkage and cracking in concrete, allows for thinner slabs and structural members, allows for slabs built on soft ground, and post tensioning helps resist earthquakes.
Post Tensioning should only be installed by qualified and knowledgable industry experts and at Nehemiah Rebar, we think we have the best in the industry!
