Injections in construction industry

Injection Technology in the Construction Industry

Advanced Sealing, Strengthening & Waterproofing Solutions

Injection is a non-invasive, high-performance technology used in the construction industry to seal, strengthen, and repair structures without dismantling or interrupting their operation. Whether applied to aboveground or underground structures, injection offers effective, durable protection in dry, moist, and even high-pressure water conditions.

🧱 What Is Injection?

Injection involves introducing specially formulated pumpable materials into cracks, joints, voids, or porous areas of a structure. Once injected, the material cures and bonds to the substrate, restoring strength, waterproofing properties, and long-term integrity.

Injection is performed using low-, medium-, or high-pressure systems, depending on the structure’s condition and repair goals. It allows for targeted solutions to problems such as leakage, settlement, soil erosion, or structural degradation, all without excavation or disruption.

🔧 Applications in the Construction Industry

Injection techniques are used across all areas of civil, residential, industrial, and infrastructure projects, including:

Sealing cracks, fractures, joints, and construction joints in concrete and masonry
Executing horizontal barriers in walls to prevent capillary moisture rise
Sealing expansion joints, diaphragm walls, sheet pile walls, and pile retaining walls
Sealing tanks, reservoirs, pipe penetrations, and sleeves
Strengthening contact zones between sealing systems and concrete structures
Curtain injection – trenchless waterproofing of underground walls from the outside
Filling voids and cavities within structures or between soil and foundations
Injection between old and new pipe linings, and around hydropower screw turbines

🔍 Injection Techniques

We apply various injection methods depending on the problem and the environment:

Injection Type	Application
Gravity-fed injection	Impregnation of porous substrates, filling voids and empty spaces
Low-pressure injection	Sealing fine cracks and microcracks in wet/dry concrete
High-pressure injection	Structural reinforcement, sealing joints under pressure
Waterproofing injection	Targeted water-sealing of cracks and expansion joints
Curtain injection	External waterproofing between underground structures and surrounding soil
Structural injection	Restoring load-bearing capacity and long-term sealing in critical zones
