Oil-Soaked Concrete Crack Repair
Epoxy Injection Systems That Bond to Oil-Contaminated Surfaces
Oil-Soaked Concrete Crack Repair Solutions
Oil spills, hydraulic leaks, and lubricant residue can permanently contaminate concrete—making traditional crack repair nearly impossible.
ZDSpoxy epoxy systems are engineered with oil-tolerant chemistry that penetrates, bonds, and cures in oil-exposed substrates, restoring strength without deep slab replacement.
Whether you’re fixing cracks in factory floors, garage slabs, or equipment bays, our systems seal from within—even in 0.02mm microcracks.
- No middlemen
- Fast prototyping

Why Standard Epoxy or Cement Fails on Oil-Stained Concrete
| Problem | Consequence | ZDSpoxy Solution |
| Oil in cracks or surface pores | Epoxy bead-up or curing failure | Oil-tolerant low-viscosity resin (ZDS2002AB) |
| Cement patch delamination | No bond to oil-impregnated surface | Structural epoxy injection only |
| Crack reopens after traffic | Poor filler adhesion under stress | Deep penetrating resin cures in-place |
- ✅ Works on motor oil, cutting fluid, diesel, hydraulic oil residues
- ✅ Zero shrinkage, high structural bond
- ✅ Suitable for slabs, machine pads, walls, pits, garages
Recommended Products
| Model | Key Feature | Application |
| ZDS2002AB | Ultra-low viscosity, oil-tolerant | Microcracks (0.02–1mm) in oil-soaked slabs |
| ZDS2870AB | Moisture-tolerant primer | Optional primer before overlay if needed |
| ZDS2771AB | Knife-grade mortar for surface patching | Rebuilding surface after crack repair |
Where You’ll Use It
- Automotive repair shop floors
- CNC / machining workshop slabs
- Warehouse loading dock pads
- Parking garages with oil drips
- Heavy equipment maintenance areas
- Old factories with deep substrate oil
Installation Guidance
- Scrub crack area to remove surface oil (solvent, degreaser, mechanical brushing)
- Vacuum out loose debris
- Inject ZDS2002AB using twin cartridge or pump from bottom port up
- Observe full fill (resin exit at upper port)
- Allow 24–48h cure before mechanical traffic
- Finish with ZDS2771AB patch mortar if surface rebuild is needed
Real Use Case
A vehicle assembly plant had 0.1–0.3mm slab cracks below conveyor pads. Standard epoxy failed to adhere.
ZDSpoxy’s ZDS2002AB bonded into the oil-saturated concrete with no whitening or backflow. Crack was sealed without slab removal.
Traffic resumed after 48h. After 8 months: no re-cracking.
Oil isn’t the end of concrete repair.
ZDSpoxy’s injection systems go beyond surface prep—they bond through oil to restore structural performance.
