Post-tensioning services
Post-tensioning design supports the Leadership in Energy & Environmental Design (LEED) sustainability goals. 

Post-tension buildings use 20% to 30% less concrete than traditionally reinforced projects. 

Post tensioning allows for thinner slabs and longer spans between columns. This creates more daylight and air flow for better indoor environmental quality.

Post-tensioning services
PTC Inc can accommodate projects that need a high recycled content by request. At the end of each project, PTC Inc provides a summary of the total recycled content of the material supplied along with mileages to originating materials.

PTC Inc supplies a top-of-the-line system for all bonded projects. Our detailers use the latest technology to produce clear, concise drawings. This allows for a critical review process before construction begins.
