Hydronic Radiant Floor Heating in Post Tension Slab-on-grade Foundations
The structural department recently designed and observed the construction of a post tension slab-on-grade foundation that incorporated a hydronic radiant floor system. Although there is nothing special about a hydronic radiant floor system in the basement floor, many builders and owners wonder if it can be done with a post tension slab. In fact, with [...]
Villas at Park West Multifamily Post Tension Foundations
The post tension slab foundations are looking great at The Villas at Park West. EVstudio was hired by C and L Development to design the PT slabs located in Pueblo. The picture above is a great example on the interior smooth finish and the exterior broom finish. The smooth finish at the interior works well [...]
Post Tension Slab-on-Grade Foundation
A Post Tension (PT) slab-on-grade (SOG) foundation is based on a typical raft SOG foundation with one major difference; high strength steel tendons pulled into tension. Tendons are typically ½” diameter made of 7 steel wire strands that is then greased and encased in a plastic coating. The grease and plastic coating helps to allow [...]

For most people it makes perfect sense to simply use the rib width as the only bearing area when determining soil bearing pressure. That’s how a wall on grade or footing foundation works as the basics learned in school. However, post tension [...]
