What is a post-tension slab?

As a leading concrete contractor in Tucson, we specialize in various concrete construction techniques, including post tension slab. Our team of experienced professionals has successfully completed numerous post tension slab projects, providing high-quality and durable concrete structures for our clients.

But what exactly is a post tension slab, and how does it differ from a conventional concrete slab? Let’s dive into the details.

A post tension slab is a type of reinforced concrete slab that uses high-strength steel cables (tendons) to provide additional support and durability. These cables are tensioned after the concrete has been poured and cured, using hydraulic jacks. This tensioning process helps to increase the strength and durability of the slab, allowing it to withstand heavier loads and resist cracking and other types of damage.

Post tension slabs are commonly used in commercial and residential construction projects, particularly in areas with poor soil conditions or high seismic activity. The added strength and durability provided by the post tensioning process make these slabs ideal for supporting large buildings, bridges, and other structures.

Now, you may be wondering how we, as concrete contractors, provide post tension slab services to our clients. Here’s a brief overview of our process:

Consultation and Design

The first step in any post tension slab project is to consult with our clients to understand their specific needs and requirements. We work closely with architects, engineers, and other professionals to develop a detailed design plan that meets our clients’ needs while also complying with all local building codes and regulations.

Excavation and Preparation


Once the design plan has been finalized, we begin the excavation and preparation process. This typically involves clearing the site of any existing structures or debris, leveling the ground, and creating a sturdy base for the slab. We also install any necessary plumbing or electrical systems at this stage.

Pouring and Curing the Concrete

Once the site has been prepared, we pour the concrete for the slab. We use high-quality concrete mixtures that are designed to withstand the specific conditions of the site and provide maximum strength and durability. After the concrete has been poured, we allow it to cure for a specified period of time, typically several days.

Post Tensioning

After the concrete has cured, we begin the post tensioning process. This involves inserting high-strength steel cables into the concrete slab and tensioning them using hydraulic jacks. The tensioning process helps to strengthen the slab and ensure that it can support the weight of the structure and resist damage from seismic activity or other forces.

Finishing and Cleanup

Once the post tensioning process is complete, we finish the surface of the slab using a variety of techniques, including stamping, staining, or polishing. We also perform any necessary cleanup to ensure that the site is safe and free from debris.

At Tucson Concrete Pros, we are committed to providing high-quality, reliable post tension slab services to our clients. We use only the best materials and equipment, and our team of experienced professionals has the skills and expertise needed to complete even the most complex projects.
