Building Post Tensioned Slab

Engineering Efficiency with MSIL's Proven Post-Tensioning Technology

For over three decades, Maurer Sanfield India Limited (MSIL) has been at the forefront of structural innovation, delivering high-performance post-tensioned slab systems that redefine modern building construction. Leveraging our deep expertise and advanced engineering solutions, we empower designers, builders, and owners to construct more durable, functional, and sustainable structures.

Advantages of post-tensioning floor slabs

Benefits for Owners & Structural Designers

Extended Slab Spans: Fewer internal columns lead to more open and flexible architectural layouts.
Reduced Slab Thickness: Achieve a lower structural profile, allowing more floors within the same building height.
Enhanced Crack Control: Improved shrinkage crack resistance ensures better water tightness and long-term durability.
Minimized Deflection: Maintains structural integrity and comfort under service loads.

Benefits for Contractors

Optimized Material Usage: Significant reduction in concrete and reinforcement steel consumption.
Lighter Foundation Load: Reduced structural weight decreases foundation requirements.
Faster Construction Cycles: Less material and simpler designs result in shorter timelines.
Smooth Soffits: Eliminates uneven undersides, simplifying the installation of electrical, HVAC, and plumbing systems.

Application fields

Building Floor Systems

Maurer Sanfield post-tensioning systems can be used in the construction of the floor slabs / Beams for a wide range of building types:

These systems are particularly beneficial for large-span designs and vertical structures, where design flexibility, cost-efficiency, and structural integrity are paramount.

End-to-End Solutions From Design to Execution

Range of solutions

Multi-strand PT anchorage system – Bonded

The anchorage assembly is comprised of a bearing plate (trumplate), a thrust block, and a set of wedges. The cast-iron bearing plate is integrally cast within the concrete matrix, serving to disperse the prestress force into the structural element. The thrust block bears against the trumplate, while the wedges mechanically engage and secure the prestressing tendons.

Single strand flat PT anchorage system – Unbonded (1S13/15)

The 1S13/15 single-strand system is typically employed for unbonded post-tensioning tendons. Its composition includes: (1) a pre-greased and sheathed strand, positioned within the slab formwork prior to concrete placement; (2) a cast-iron anchorage assembly equipped with steel wedges, which is embedded in the concrete to secure the strand and transfer the prestress load to the structure; (3) a plastic conduit providing localized protection to the strand where the sheathing is removed within the anchorage zone; and (4) a grease-filled protective cap designed for long-term corrosion prevention at the anchorage.
