YURU Acrylate Acid Resin Grouting Material
YURU Acrylate Grouting Material
YURU Acrylate Grouting Material is a two-component chemical injection grout designed for seepage control and flexible water sealing. Its low viscosity allows the material to enter fine cracks, joints and suitable permeable areas before forming an elastic, water-responsive gel.
The material is used in underground waterproofing, tunnel lining seepage treatment, dam and reservoir seepage control, and suitable concrete or rock cracks.
Three formulation options are available, including our existing formulation, AG Type I and AG Type II. Each has its own reported technical performance, so the formulation should be confirmed against the project’s injection conditions and required properties before ordering.
YURU also supports OEM/ODM and customized acrylate grout formulations. We can discuss adjustments to gelation time, viscosity, packaging and other product characteristics based on the customer’s construction process and project requirements. Customized specifications are subject to technical feasibility and performance verification.
Features & Benefits
Good permeability
Acrylate grouting material has high fluidity and good permeability, and can fully fill small cracks and gaps.
Adjustable Gelation Time
YURU offers different acrylate grout formulations and supports project-specific adjustments to gelation time where technically feasible. The appropriate working and reaction characteristics depend on the injection conditions, treatment area and construction requirements.
Low Viscosity and Fine Penetration
The grout is designed to reach fine cracks and seepage paths in suitable concrete, rock and underground waterproofing applications.
Sealing leaks
Low viscosity, high permeability environmental grouting material, suitable for any dense complex structure.
Excellent stability
The low shrinkage formula with high viscosity, strength and toughness can effectively reduce the repeated seepage of foundation settlement or structure expansion. Acrylate grouting materials have excellent stability in water, do not dissolve or drain, ensuring that they can still function in humid environments. This feature makes the material particularly outstanding in projects such as basements and tunnels that require long-term anti-leakage.
Flexible Water-Sealing Gel
After the components react, the material forms a flexible gel that can expand when exposed to water, helping reduce seepage through the treated area.

Applications of YURU Acrylate Grouting Material
Dam and Reservoir Seepage Control
Anti-seepage grouting; fine cracks, rock fissures, permeable zones; selected curtain grouting.
Tunnel and Underground Passage Waterproofing
Suitable for seepage treatment in tunnel linings, metro tunnels, railway tunnels, and underground passages. The grout may be injected into fine cracks and suitable joints to seal groundwater leakage pathways.
Basement and Underground Building Waterproofing
Basement walls, construction joints, floor-wall junctions; low-viscosity for narrow/concealed openings.
Concrete and Rock Crack Sealing
Acrylate grout may seal suitable non-structural cracks in concrete and fissures in rock where the primary objective is reducing water penetration. The flexible gel forms a water-sealing barrier within the treated zone.
Permeable Ground and Seepage Cut-Off Grouting
Applied in selected ground-treatment applications where water migrates through permeable soil or fine seepage channels. Acrylate injection can reduce groundwater permeability and may provide localized soil consolidation under suitable conditions.
Permeable Ground and Seepage Cut-Off Grouting
Suitable for selected injection repairs in kitchens, bathrooms, utility areas and other building spaces affected by water seepage. The leakage path and surrounding substrate should be assessed to determine whether injection grouting is appropriate.
For projects requiring structural crack bonding, bulk void filling or emergency control of severe flowing water, review our guide on when not to use acrylate grout before selecting a product.
Acrylate Grouting Material Application Steps
Checking:
Check the leaking part, clean the leaking part, confirm the crack type, drill hole, install the grouting nozzle on the effective grouting hole.
Mix in proportion:
According to the proportion of materials prepared into A, B two components, the use of double liquid high-pressure grouting machine, according to the volume of 1:1 construction, grouting machine should be kept dry before construction, no dirt.
Grouting:
Starting from the first grouting nozzle from low to high, grout is injected and the pressure is gradually increased. When the grout appears in the adjacent grouting hole, it is moved to the next adjacent grout hole and the grout is continued. After all grout is finished, it is returned to the first grouting nozzle and grout again.
Operation after grouting:
72 hours after the completion of grouting, check the leakage site for water seepage. If there is no water seepage, remove the grouting nozzle and seal and smooth the base surface with epoxy mortar or quick-dry cement.
After construction:
After construction, immediately use cleaning agent to clean the desired equipment and tools in contact with slurry. Waste should be centralized treatment, not discarded at will.
The logistics is fast, the goods are intact, the product quality is good, it is used for waterproofing repairs on roof gaps, the effect is good, and I am very satisfied.
