1) Shallow Honeycombing (<10mm Depth): Used Mainly For Aesthetic Restoration. o Method: Apply A Dry Pack Or Stiff Mortar (1:3 Cement-Sand Ratio) By Pressing It Into The Voids With A Trowel. 2) Medium Honeycombing (10mm To 50mm Depth): Addresses Potential Durability Issues. o Method: Use A Polymer-Modified Mortar Or High-Strength Cement Grout. A Bonding Agent Is Often Applied First To Ensure Adhesion To The Existing Concrete. 3) Large Or Deep Honeycombing (>50mm Depth): Required For Structural Integrity.
o Method: Often Involves Pressure Grouting Or Micro-Concrete. For Very Large Repairs, Shotcrete (Sprayed Concrete) May Be Applied In Layers.

1) Surface Preparation: Carefully Chip Away All Loose Or Weak Material Using A Hammer And Chisel Or Light-Duty Jackhammer Until Sound, Dense Concrete Is Reached.
2) Cleaning: Use A Wire Brush To Clean Any Exposed Reinforcement Steel And Wash The Area With Clean Water Or Compressed Air To Remove All Dust And Debris.
3) Bonding: Apply A Bonding Agent, Such As An Epoxy Primer Or SBR-Latex Slurry, To The Dry Surface To Improve The Bond Between Old And New Material.
4) Manual Filling: Pack The Repair Mortar Or Grout Into The Cavity, Ensuring No Air Pockets Remain.
5) Pressure Grouting: For Deep Voids, Install Injection Nipples And Pump High-Strength, Non-Shrink Grout (Like Conbextra GP2 Or Solid Cure )Until All Voids Are Saturated.
6) Finishing And Curing: Smooth The Surface With A Trowel To Match The Surrounding Area.
7) The Repair Must Be Cured For At Least 7 Days Using Water Or A Curing Membrane To Prevent Shrinkage And Achieve Full Mechanical Strength.
