OMNITEK® RM Fiber

Advantages

• High early- and final strength properties to strength class C60/75 for structural repair of concrete.
• Polymer modified for an excellent adhesion, and fiber reinforced for a long-term durable repair without surface cracks.
• High carbonatation, chloride, freeze-thaw and chemical resistance for maximum durability in all exposure conditions.
• Stiff plastic consistency for fast, easy and cost effective application by manual application in horizontal and vertical applications.
• CE certified according to EN 1504-3.

Field of Application

OMNITEK® RM Fiber is a most durable solution for all structural and non-structural concrete repair applications, such as:

• General concrete repairs in vertical and horizontal conditions, as well as re-profiling applications of joints, edges and damaged precast elements and concrete structures.
• Repair of concrete structures exposed to sea water, corrosive environments or severe freezing conditions such as:
  • Repair applications on concrete in contact with or buried under aggressive soil/ground water.
  • Road and bridge decks or structures exposed to de-icing agents.
  • Marine structures exposed to splash zones

1. Preparation of Substrate

• Substrate preparation has to be according EN 1504-10 part 7.
• The substrate has to be free from dirt, grease, laitance, loose concrete, loose particles or layers which could adversely affect adhesion.
• Remove all damaged concrete and prepare substrate by sand or grid blasting, high pressure water jetting, or other methods until base concrete is exposed, offering sufficient roughness (bond) and open pores.
• The substrate must be pre-wetted with clean water until saturated. The substrate should be damp, but without free standing water.
• The substrate must be frost-free and have a cohesion of minimum 1.5 N/mm².
• Exposed or corroded reinforcement steel needs to be treated with OMNITEK® CPC.

2. Mixing

• The product has to be mixed using a suitable forced action mixer (400-600rpm). The mixing head must be completely immersed in the powder.
• Add 4/5 of the required quantity of water into the mixer and mix for 2 minutes. Add the remaining quantity of water. The water content can be varied to obtain the desired consistency. Never use more than the maximum water quantity. Mix for an additional 2 minute until a lump-free, homogeneous mixture is obtained.
• The mixing time depends on the type of mixer. 4 minutes is the minimum.
• Once the mortar is ready mixed, apply immediately. Do not prepare more material than can be used within the open time of the material.
• When the mortar starts to set, remix but never add more water.

3. Application

• The mortar is applied manually using a trowel. Alternatively suitable spray equipment can be used.
• Press firmly into the application area to ensure proper adhesion and to compact the material. Take particular care in the areas around and behind reinforcement bars.
• The material can be applied in several layers. Especially when repairing large voids it is recommended to work in several application steps.
• Do not apply the material if the ambient temperature is below 5°C or expected to fall below 5°C within 24 hours.
