Why Post Tension?
Post-tensioning is the slab reinforcement methodology of choice for post-tension slab-on-ground, elevated slab applications and more. This engineered solution creates cast-in-place, prestressed concrete by reinforcing the foundation after the concrete has been placed. In unbonded post-tension construction, tendons are placed prior to concrete placement, and once the concrete reaches a specific initial compressive strength, the tendons are stressed to a specified force and anchored. This method of post-tensioning’s external compressive force makes the concrete more resistant to the tensile stresses that would otherwise cause a foundation to pull apart and crack.
Post-tensioning Offers the Builder a Number of Advantages
Post-tension concrete construction provides:
Greater Flexibility of Design
Engineers can flexibly meet any geometric floor plan and use varying section dimensions in the slab.
Reduced Cost of Post-Tension Construction
Post-tension technology enables post-tensioned slabs to be constructed of a reduced volume of concrete, thereby reducing the builder’s foundation costs and providing a more economical foundation solution.
Adaptability to Most Soil Conditions
Post-tension is an appropriate method of foundation reinforcement for stable soils and highly expansive soils alike.
Reinforcement for a Variety of Applications
Post-tensioning is the reinforcement method of choice for both residential slab-on-ground and elevated slab applications, including single family homes, industrial floors, high rise buildings and much more.
LEED Points for Green Building Initiatives
Using post-tensioning materials can add LEED (Leadership in Energy and Environmental Design) points toward a Green Building Certification in accordance with the U.S. Green Building Council’s rating system.
