High Strength Composite Laminate Structural Strengthening System For Concrete Structures


Estoplate is a Carbon Fiber Laminates Strips, composite material for reinforcement of new and the strengthening of existing structures. The material exhibit excellent resistance towards corrosion and is able to dissipate energy as required in earthquake scenarios. It comes in various thicknesses of carbon strips (mm). They are  known as;

  • Estoplate CLS – High Strength Type
  • Estoplate CLM – High Modulus Type


Estoplate is used for strengthening columns and beams  of load bearing structures specifically where improvement to shear strength and deformation properties is required. Typical applications include piers, columns, connecting beams and slabs of railway and road bridges, buildings and towers.

In the following structures:

  • Commercial, high rise
  • Industrial plants
  • Warehouses
  • Bridges, Tunnels, Jetties
  • Pipes, Culverts, Chimneys
  • Power Station plants


  • Ultra high tensile strength modulus
  • High thermal conductivity
  • Electrical conductivity
  • Excellent chemical resistance
  • Excellent fatigue resistance
  • Excellent to resistance to high temperatures
  • Will not corrode
  • Lightweight hence easy to handle and use
  • Good Creep and Damping Properties
  • Excellent fire resistance

Durability Description

Estoplate Strips tensile strength can be stable for 10,000 hours with accelerated exposure test (it is equivalent to 30 years natural exposure), providing:

It is used in strict accordance with the manufacturer’s recommendations.

It is used within the design parameters stated in this datasheet.

It is used in conjunction with other approved building systems and materials.

Durability covers weathering and adhesive characteristics. For conditions outside those stated in this data sheet, contact Estop Technical Specifications Department.

Estop reserves the right to modify this time period, depending on but not limited to climatic, site and environmental conditions such as chemical  attack, abrasion, water immersion and adverse climatic and temperature conditions.

Application Instruction


Concrete surfaces must be dry, smooth, sound and free from debris and loose material. Surfaces must be fully cured and free from contamination.

Through preparation of the substrate is vital with light grit blasting recommended to remove all deleterious substances and provide a suitable key. All dust and debris must be removed prior to proceeding. Blow holes or imperfections should be filled with Estorex Putty or Estocrete WR prior to application of Estoplate Adhesive.


The base and hardener components of Estoplate Adhesive should be thoroughly stirred before the two are mixed together.

Pour the hardener into a suitably sized mixing vessel and add the base resin into the hardener. The use of a heavy- duty slow speed, flameproof or air driven drill fitted with a mixing paddle is desirable. Mix these components in the quantities supplied taking care to ensure all containers are scraped clean.

Apply Estoplate Adhesive to the prepared substrate using  a  stiff  brush,  working  the  Adhesive  well  into the substrate at a coverage rate of 0.3kg/m .


Arrange enough material, manpower and equipments to carry out the application within the resin’s pot life. The base and hardener components of Estoplate Adhesive must be used up once mixed.

Immediately after the application of Estoplate Adhesive install the Estoplate once the Estoplate Adhesive cured.
