Application Procedure
Surface Preparation
The surface of structure element that are still in good condition or restored should be profiled. With degraded structures the whole layer should be removed by scarifying, hydro demolition, then structural restoration carried out using suitable structural grade repair mortar. Oil, grease, dust or any other loose material from the surface. Clean up the Laminate surface.
Application
Apply one layer of DanLMEP about 3mm thick on the surface of laminate, and a thin layer on substrate. Apply DanLM and using a roller apply uniform pressure by moving the tool both ways in the direction of fibres.
Finishing
Surface should be top coated within two days to assure proper adhesion to laminate. Surface should be properly protected against plastering or mortar.
Storage & Shelf Life
DanLM is to be stored under cover, out of direct sunlight and protect from extreme temperature
Safety Precautions
As like all chemical products, care should be taken during use and storage to avoid contact with eyes, mouth, skin, and foodstuffs. Use safety goggles on site if sometimes to protect during releasing the laminate roll, as it may tightly wound in roll form during manufacturing with reverse spring action.

Carbon anchors, typically made from strong, lightweight carbon fiber (CFRP), are crucial for strengthening concrete structures by preventing premature debonding of externally applied CFRP sheets, allowing them to reach full tensile strength, enhancing load capacity, especially for shear/impact, and providing durable, low-profile reinforcement for beams, columns, and foundation walls. They work by mechanically locking the CFRP to the concrete, often involving drilling holes, inserting anchored CFRP plugs, and splaying them out, making them effective for both flexural and shear strengthening.
How Carbon Anchors Work & Their Benefits
- Overcome Debonding:CFRP sheets alone often debond before fully activating, but anchors transfer stress, allowing up to 100% of the material's strength to be utilized.
- High Strength & Lightweight:Carbon fiber offers superior strength-to-weight ratio compared to steel, adding significant capacity without much added mass.
- Durable & Corrosion-Resistant:Provides a long-lasting solution, ideal for harsh environments where traditional steel might corrode.
- Versatile Applications:Used for beams, columns, bridge strengthening, historical retrofitting, and foundation wall reinforcement.
- Enhanced Performance:Significantly improves shear capacity, reduces crack propagation, and helps maintain performance under dynamic/impact loads.
Common Applications
- Flexural Strengthening:Adding strength to beams and slabs.
- Shear Strengthening:Anchoring U-shaped CFRP wraps to increase shear resistance.
- Seismic Retrofitting: Improving performance of beam-column joints.
- Crack Control: Used in bridges to control cracking.
