Epoxy Grout
High-Penetration Epoxy Resin Injection Grout
Two-component low-viscosity epoxy that penetrates fine structural cracks, restoring monolithic strength to load-bearing concrete.
Suitable Environment
- Dry environments
- Slightly damp environments
- Not recommended where active running water is present
01 / Features
Key Highlights
- 01Low viscosity for deep penetration into hairline cracks
- 02Strong adhesion to concrete substrates
- 03Forms a high-strength rigid structure on cure
- 04Non-foaming and non-shrinking
- 05Combined repair and structural reinforcement
02 / Applications
Application Scenarios
- Cracks in load-bearing structures
- Beam, column, and slab cracks
- Structural reinforcement projects
- Concrete structure repair

04 / Installation
Application Guide
- 01Clean dust and debris from the crack surface; install packers and check seal
- 02Drill packer holes intersecting the crack at 25–30 cm depth, alternating 45° on either side
- 03Mix components A and B at 2:1 by weight; stir uniformly until homogeneous
- 04Inject with a single-liquid high-pressure pump; start from the lowest port, progress upward
- 05Retain pressure until slurry appears at the adjacent port, then move on; repeat sequentially
- 06After 24 hours, QA-inspect; remove packers and finish surface with cement mortar
- Do not use dual-liquid pumps — mix A + B externally and pump as a single liquid
- Mixing tools must be clean and dry; mix only the volume usable within working time
- Confirm injection bore intersects the crack before pumping
- Workable time is > 30 min — schedule batch sizes accordingly
05 / Storage & Safety
Transport, Storage & Safety
Storage & Transport
Non-flammable, non-explosive solvent-free formulation — transport by normal methods. Store sealed in a cool, dry place. Maximum storage temperature ≤ 40 °C.
Shelf Life
12 months from manufacture date under normal transport and storage conditions
Precautions
- Operators must wear PPE; rinse with clean water and seek medical attention on contact
- If site water inflow is high, perform leak stoppage with a hydrophobic PU grout first, then return for structural epoxy grouting
- Reaction is exothermic — over-mixing or excessive batch size can cause heat build-up; mix only what is needed
- Do not blend with other materials — contact Yifeng technical service for assistance
