Epoxy Concrete Repair Systems
Structural Injection, Patching & Filling for Damaged Concrete
Epoxy Concrete Repair
ZDSpoxy’s Epoxy Concrete Repair Systems are engineered for permanent structural rehabilitation of cracked, delaminated, or oil-contaminated concrete. Whether it’s injection sealing micro-cracks, patching spalled columns, or filling voids on wet substrates, our epoxy-based systems deliver high bond strength, chemical resistance, and zero shrinkage—even in the harshest conditions.
- No middlemen
- Fast prototyping
- Private label available
What Makes Concrete Repair Fail?
| Failure Mode | Common Cause | ZDSpoxy Fix |
| Crack reopens | Cement filler shrinks or weakens | Use structural epoxy injection (ZDS2002AB) |
| Delamination or blistering | Moisture behind repair area | Apply ZDS2870AB primer before patch |
| Peeling or chalking surface | Incompatible topcoat or UV damage | Use ZDS2186AB anti-yellowing topcoat |
| Repair doesn’t bond to oil | Oil residue in cracks or surface pores | Oil-tolerant injectable epoxy |
ZDSpoxy Repair System Matrix
| Problem Type | System Type | Recommended Product(s) |
| Hairline cracks (0.02–0.3 mm) | Injectable low-viscosity | ZDS2002AB, ZDS2013AB |
| Deep cracks (≥3mm) | Pourable epoxy grout | ZDS3382AB |
| Vertical or overhead repair | Knife-grade epoxy mortar | ZDS2771AB, ZDS1007AB |
| Oil-contaminated concrete | Oil-tolerant injection | ZDS2002AB |
| Wet substrate or underwater | Water-curing systems | ZDS1417AB, ZDS2013AB |
| Final coating or surface seal | Chemical/UV resistant topcoat | ZDS2186AB |
Why Epoxy Is Better for Structural Repair
- ✅ Penetrates Deep into Cracks (vs. surface-only fillers)
- ✅ High Bond Strength on Concrete & Steel
- ✅ Zero Shrinkage = No Reopening
- ✅ Resists Oil, Water, Acid, and Salt Spray
- ✅ Cures in Wet or Submerged Conditions
- ✅ Injection, Pourable & Knife-grade Options Available
Typical Repair Applications
- Structural beam or column crack injection
- Spalled concrete patching
- Oil-soaked garage floor repair
- Industrial floor joint edge rebuild
- Parking structure deck delamination fix
- Moisture-damaged cold room concrete repair
- Bridge deck waterproofing prep
- Seawall or port infrastructure crack sealing
Installation Guidance
- Injection systems: Use 2-part cartridge or pressure pot for 0.02–0.3mm cracks
- Knife-grade repair: Apply in layers, avoid thick fill at once
- Wet substrates: Prime with ZDS2870AB
- Underwater repair: Apply ZDS2013AB or ZDS1007AB using diver method or on wet surfaces
- Surface topcoating: Seal cured repair with ZDS2186AB for UV/chemical resistance
Use Case Highlight
A precast factory used ZDS2002AB to inject epoxy into 0.05mm cracks on an oil-exposed production slab.
In a separate project, ZDS2771AB was used to patch overhead spalling under a bridge deck without any sagging or slump.
Final surface coated with ZDS2186AB for chemical protection and clean finish.
Don’t just cover the cracks—repair them structurally.
