Structural Strengthening (FRP & Reinforced Plaster Systems)

Seismic Retrofit Solutions for Concrete & Masonry Structures.

We install structural strengthening systems using FRP wraps and fibre-reinforced plaster systems — increasing seismic resilience, crack control, and long-term durability of concrete and masonry buildings.

PCR offers engineered structural strengthening for seismic upgrades and code compliance on concrete and masonry structures across New Zealand. We apply FRP (Fibre-Reinforced Polymer) systems and fibre-reinforced plaster overlays designed to improve structural capacity, out-of-plane resistance, and crack control.

These systems are lightweight, non-intrusive, and ideal for retrofitting heritage buildings or operational assets. We work closely with structural engineers and product suppliers to tailor solutions to each project’s needs and constraints.

✅ Strengthening Methods We Offer:

🧱 FRP Systems (Fibre-Reinforced Polymer)

  • Carbon or glass fibre wraps, laminates, and rods
  • Applied to beams, columns, slabs, and shear walls
  • Increases load-carrying capacity and confinement
  • Quick to install, low-profile, and corrosion-resistant

🧱 Fibre-Reinforced Plaster Systems

  • Applied over brick, block, or concrete substrates
  • Reinforced with mesh and structural adhesive
  • Improves out-of-plane strength, crack resistance, and ductility
  • Suitable for seismic upgrades and heritage buildings
  • Compatible with architectural coatings or mineral finishes

🛠 Typical Strengthening Scopes:

  • Heritage and council-owned buildings
  • Brick and masonry facades and parapets
  • Seismic risk upgrades to concrete-framed buildings
  • Reinforcement of load paths and structural joints
  • Schools, churches, commercial buildings, and infrastructure assets
