Wide slab floor Torque Reinforcement System

S&P C-Laminate LM combined with S&P Resin 220HP epoxy adhesive is the solution for suspected wide slab floors. The system is fully proven and can be installed with very little inconvenience.

After the collapse of the parking garage in Eindhoven, we brought our international knowledge and experience together and started looking for a suitable solution. As a manufacturer and supplier of carbon fiber-based materials, we are close to the market and an independent partner for all constructors.

Our S&P C-Laminate has been successfully applied for 25 years in reinforcement measures of concrete structures in the broadest sense of the word. From openings, voids and spans to the reduction of existing reinforcement (corrosion) in structures. You will also find our carbon reinforcement in repair measures of cantilever balconies, galleries and reinforcement of masonry in earthquake areas.

The S&P Wide Plate Floor Coupling Reinforcement System has been investigated and tested on similar wide plate floor elements at the TU-Eindhoven. In cooperation with renowned parties, we developed a repair system, inclu- sive calculation model. In addition to the proven structural safety, the reinforcement measure has a low impact on the environment and nuisance is kept to a minimum.

The test pieces are identically shaped and dimensioned as the plates at the in- cident at the parking garage in Eindhoven.

The cause of the slab collapse in the parking garage in Eindhoven was ascertained prior to the investigation.

This study at TU-Eindhoven looked at:

- Whether gluing an external carbon lamella could be a reinforcement measure.
- At the same time, it was examined whether the loads that would eventually be met, theoretical and computer simulations performed in DIANA, would match the actual failure loads."

Several tests were conducted with different amounts of carbon lamellae. In addition, plates were pre-loaded where an initial detachment between shell and compression layer was applied to simulate delamination already present. The conclusion of all these studies is that the reinforcement measure is excellent performance and the final failure loads during these tests are in full agreement with the computer models.

S&P Wide Plate Floor Coupling Reinforcement System:

• S&P provides full technical support
• System has been extensively tested
• Various references available
• No risk of piercing the existing reinforcement,concrete core activations or pipes
• Applicable in buildings while in use
• Dust-free system
• Very limited to no noise
• Light weight
• Easy to apply + full training installers

Fire protection

Fireproofing the carbon adhesive reinforcement is not necessary in most cases. When fire retardancy on the measure is still necessary, S&P has a standard solution available for 30, 60, 90 and 120 min fire resistance duration.
