Crack Injection Grouting

Precision Repair. Reinforced Stability.

Cracks in concrete structures—whether due to settlement, shrinkage, thermal movement, or structural stress—can compromise both safety and longevity. At Ethios Group, we offer advanced crack injection grouting solutions that restore monolithic integrity to concrete elements and prevent further deterioration.

Using high-pressure injection techniques, we fill and seal cracks internally, ensuring deep penetration and long-lasting results without the need for surface demolition.

Our Crack Injection Grouting Systems Include

‍

Epoxy Injection Grouting - Ideal for structural cracks, this method uses low-viscosity epoxy resins that bond cracked sections and restore original load-bearing capacity. Commonly applied in columns, beams, slabs, and foundations.
‍
Polyurethane (PU) Injection Grouting - Designed for leak-sealing and non-structural cracks, PU resins expand upon contact with moisture to form a flexible, water-tight seal. Effective for active water leaks in basements, water tanks, retaining walls, and underground structures.
‍
Acrylic and Microfine Cement Grouts - Used in fine cracks, voids, and porous substrates for waterproofing and stabilization purposes in tunnels, podiums, lift pits, and bridge decks.

Typical Applications

Structural cracks in beams, slabs, and columns – To restore monolithic integrity.

Active water leakage in basements and tanks – For internal sealing under pressure.

Cracks in retaining walls and foundations – To prevent seepage and deterioration.

Cold joints and construction gaps – To bond disjointed concrete segments.

Honeycombed concrete zones – For void filling and reinforcement.

Pre-treatment before waterproofing or surface coating – To ensure surface stability.

Key Benefits

Compatible with existing concrete and reinforcement.

Effective even under hydrostatic pressure (for PU).

Deep penetration and long-lasting sealing.

Restores structural functionality and appearance.

Minimal surface disturbance and fast execution.

Our expert team conducts a thorough site inspection, crack mapping, and material selection to ensure the best-fit injection technique for every project. With high-precision equipment and globally trusted grouting materials, Ethios Group guarantees lasting results that reinforce the strength and safety of your structure from within.
