Concrete Enlargement Systems

Innovative Concrete Reinforcement Solutions

Tstrata Enlargement Systems™ seamlessly integrate an additional reinforced concrete layer that is fully bonded to existing structural members. Our cutting-edge system combines specific surface preparation, specialized materials, and pressurized formwork to create monolithic concrete enlargements. These systems increase or restore the load-carrying capacity, ductility, and seismic resistance to a variety of concrete structures.

Tstrata Enlargement Systems™ meet both ICRI 320.IR and ACI RAP-5 requirements for placement of concrete under pressure, and are suitable for all applications, including vertical and overhead installation.

Solution Use Cases

Our customizable strengthening solutions can be used for these various requirements.

Change in Code
Seismic Upgrade
Increased Loads
Missing or Misplaced Reinforcement
Deterioration
Low Concrete Strength

Advantages

Adds significant additional capacity
Increases axial, shear, and bending capacity
Improves stiffness and ductility
Incorporates steel dowels to supplement shear transfer requirements
Can incorporate post-tensioned reinforcement to reduce service stresses and deflection
Uniform appearance that blends well with existing structure
Provides high levels of fire resistance

Pressure sensors inside the Tstrata Pressurized Form Technology™ show high pressure is maintained after concrete placement to ensure a superior bond to the existing substrate and to minimize shrinkage.

Design Elements

Tstrata SCC Repair Material™

Self-consolidating concrete (SCC) materials to enhance consolidation in thin enlargement applications and congested reinforcement zones

Tstrata Pressurized Form Technology™

Creates pressure to force the new concrete into the prepared surface, creating a monolithic interface between the existing substrate and the enlargement Typically monitored using special concrete pressure sensors to confirm bond of existing and new concrete

Steel Reinforcement

Designs are reinforced with mild steel and/or post-tensioning to achieve the required strength and improve serviceability performance
