Junlong Polymer Grout: 9 Key Features of the New Building and Infrastructure Leak Sealing and Reinforcement System

Superior Environmental Performance

Junlong Polymer Grout features ultra-high solids content, solvent-free formulation, zero organic volatile emissions, non-toxic properties, and employs pollution-free green grouting technology.

Outstanding Weather Resistance and Aging Resistance

Junlong Polymer Grout's stable chemical structure and high cross-linking density ensure extended service life.

Exceptional Physical and Chemical Properties

Post-curing water absorption rate is extremely low at approximately 0.4%. Exhibits excellent water resistance and impermeability. No cracking at -35°C. Excellent elongation at high temperatures. No cracking or deformation during aging tests (heat aging, artificial climate aging) at constant elongation. Excellent tensile strength retention and elongation at break after heat treatment (80°C for 168 hours). Excellent tensile strength retention and elongation at break after acid and alkali treatment.

Superior Physical Properties

Sailong Polyacrylate Grout is an “elastomer” with outstanding elasticity, achieving up to 400% elongation at break. It accommodates shield tunnel segment vibration, uneven settlement at expansion joints, thermal cracking, and thermal expansion/contraction at construction joints, preventing leakage recurrence due to deformation.

Tensile Resistance & Reinforcement

Combining elasticity with tensile strength (approx. 2.3 MPa), this grout is injected under high pressure into concrete defects causing leaks. It fills voids completely, sealing leaks while enhancing tensile strength at the defect site.

Superior underwater bonding performance Cures upon reaction with water, achieving full solidification underwater. Exhibits strong bonding strength on wet surfaces or concrete interfaces submerged in water, with enhanced adhesion under pressure. Overcomes the weakness or lack of bonding strength on wet surfaces or underwater concrete interfaces common to other chemical grouting materials.

Non-solvent, non-shrink, stable performance

Junjiang Polymer Grout contains no organic solvents with nearly 100% solids content. It exhibits zero shrinkage after curing, eliminating the common issue of re-leakage caused by post-curing shrinkage in other chemical grouting materials.

Complex Area Protection

The liquid nature of Junjiang Polymer Grout facilitates application on complex surfaces including flat planes, vertical surfaces, curved surfaces, and corners.

User-Friendly Application

Single-component grouting offers simplified operation compared to dual-component systems, ensuring controllable and stable construction quality. Using a remote-controlled single-component grouting machine enables one-person operation, significantly reducing labor while maintaining quality.

Convenient Transportation and Storage

Junjiang Polyurethane Grout ships as a liquid single-component material, allowing direct on-site grouting. This accelerates material transport and minimizes storage space requirements at construction sites.
