Structural Strengthening with Section Enlargement System

CTech-LLC® Strata™ strengthening system involves placing additional reinforced concrete that is fully bonded to existing structural members in the form of an overlay or a jacket.
The Strata™ system is combination of specialized materials and pressurized formwork for rehabilitation and strengthening of concrete structures. Our system utilizes a highly flowable, non-segregating specialty concrete mixes that fill formwork and encapsulate even the most congested reinforcement zones, allowing for improved bond with the existing structure.
The pressurized formwork enables high-quality concrete pours and guarantees an integrated interface between the new and old concrete. Furthermore, the system incorporates steel reinforcement, mild steel or post-tensioning, to supplement required strength.

Key Features:

  • Strata™ system can provide increased load-carrying capacity to existing columns, beams, walls and slabs.
  • Axial, shear, and bending capacity improvement of structural components.
  • The system is used to improve or ductility & stiffness of structural members.
  • Post-tensioned reinforcement provides service stresses and deflection reduction.
  • Strata™ system utilizes specialty concrete mixes exactly according to the requirements and has good bonding properties with the old concrete.
  • The system provides improves progressive collapse and fire resistance of structure.
  • Cost effective strengthening system.
  • Strata™ system can be used with CTech-LLC® FibraOne™ system for providing high levels of force protection.
  • This system is suitable for all applications, including overhead and vertical installation.
