Concrete Repair & Special Mortars

Concrete Repair System

Based on its many years of experience and technical expertise with plasters, mortars, concrete protection and waterproofing materials, Ceresit developed a PCC concrete repair system compatible with concrete classes of at least C 12/15 (B 15)

The Ceresit system is based on four core products:

  • CD 30 ‘2-in-1’ – mineral, one-component, anti-corrosion mortar suitable also as a contact layer
  • CD 26 – coarse-grained mortar for producing layers of 30 to 100 mm thickness
  • CD 25 – fine concrete mortar for producing layers of 5 to 30 mm thickness
  • CD 24 – fine filling compound for repairing concrete up to 5 mm layer thickness.

Step by Step

Step 1

Ceresit Concrete Repair System, Step by Step 1, size 1280x960

Chisel off the corroded parts of the concrete. Remove the damaged layers of flooring, plaster and insulation. Clean the concrete surface.

Step 2

If the corrosion has already affected the reinforcement, remove the concrete in this area to reach uncorroded parts. Clean the reinforcing steel bars manually or mechanically until the bare metal is exposed, then clean with compressed air.

Step 3

Apply an anti-corrosion layer of Ceresit CD 30 on the previously cleaned steel bars. They should be wet during application of CD 30.

Step 4

Moisten the prepared concrete area with water until the surface appears to be slightly damp. Now apply a contact layer of Ceresit CD 30.

Step 5

After a drying time of 30-60 minutes when the contact layer is still slightly damp, apply one of the repair mortars in the Ceresit PCC system: either CD 25 or CD 26 – depending on the required layer thickness and depth of the cavity.

Finally, use the fine-grained filler CD 24 to produce a smooth surface.
