Advantages

  • Resistant against weak acids, microorganisms, alkali and water.

  • Ease of adjusting reaction time.

  • Easy-to-apply.

  • Hydrophobic.

  • Low-viscosity; penetrates well into capillary cracks.

  • Solvent free.

  • Reacts with water to stop leakage.

Areas of Use

  • Foundations, retention walls, cracked walls

  • Water tanks, dams, tunnels and subways

  • Wastewater and sewage systems

  • Storehouses

  • Filling layers and joints

Method of Application

Applied with a single component injection pump into the prepared pakers (injectors). The application pressure varies between 14 and 200 bars. Application should begin with the first paker (injector). A starting at low, the pressure is increased until resin overflows. When the resin overflows, the application moves on to the next paker (injector). During the injection application the resin that is injected from all pakers (injectors) will begin overflowing from the cracks on the concrete. After this procedure, the application is finalized. In the application of YAPIFINE SERUM, the consumption amount is proportional to the cracks and holes that need to be completely filled.

Packaging
  • Component A: 7.5 kg tin can
  • Component B: 0.75 kg tin can
Storage and Shelf Life

The shelf life of the product is 12 months when stored on wooden pallets in its original packaging in dry (maximum relative humidity 60%), cool (ambient temperature between +5°C and +25°C) and moisture-free environment.

The unpacked material should be used as soon as possible.

Safety Measures

No smoking should take place during application.

The work environment should be well ventilated and should not include any open flames.

Since the solvents are heavier than air it should be remembered that they will be in circulation over the floor.

The operator should be wearing proper work attire, goggles, mask and protective gloves appropriate to work and worker safety regulations.

In case of contact with the eyes, rinse with plenty of water before seeking immediate medical attention. For further information on the safe handling of this product please read the Safety Data Sheet (SDS).

Surface Preparation

All the free particles present in the cracks and joints on the surface where the injection will be made should be cleaned. Cracks larger than 3 mm should be repaired with an appropriate repair mortar.

The locations of the pakers (injectors) are determined according to where and how the leak was coming through. The pakers (injectors) are placed at a 45 degree angle.

Pakers (injectors) should be nailed all the way into half the length of the concrete thickness. The distance between the pakers (injectors) should be between 15 cm to 90 cm.

The insides of the holes should be dust free.

Application Conditions

Should not be applied to surfaces that were exposed to sunlight for too long or to surfaces that are too hot or frozen. Should not be applied when the ambient temperature is not within the values of +5°C and +35°C.

The application area should be protected from the effects of wind and direct sunlight.

The final consumption amount might vary depending on application conditions and surface characteristics.

Mixture Preparation

YAPIFINE SERUM INJ CATALYST is thoroughly mixed before use. YAPIFINE SERUM is then mixed with the given amount of catalyst and becomes ready to use. The amount of catalyst should be adjusted according to the cracks and the water’s flowing rate as well as the weather conditions at the site of the application. The catalyst can be used with a ratio between 2% - 10%.
The required amount of mixture should be prepared and then should be applied without delay.
