Injection Sealing Technology
Injection sealing is an engineering method used to stop water ingress by injecting specialised materials into cracks, joints and soil.
The material penetrates voids and forms a waterproof barrier that prevents water infiltration even under pressure.
This method is especially effective where conventional sealing methods fail or cannot be applied.

Frequently Asked Questions
The appropriate sealing method depends on the source, pressure and path of water ingress. For active leaks in underground structures, injection sealing can be used to fill cracks, joints and water-bearing zones with materials selected according to the site conditions.
Yes. In many cases, injection waterproofing can be carried out from inside the structure through small access points, avoiding external excavation and reducing disruption to ongoing operations.
When the material and injection method are correctly selected, injection sealing systems can provide long-term waterproofing performance. Durability depends on the condition of the structure, water pressure, joint or crack movement and the selected injection material.
Yes. Hydro-active polyurethane resins can react with water and expand within cracks or voids, helping stop active leaks even under hydrostatic pressure. Material selection depends on leakage intensity, crack geometry and site conditions.
Project cost depends on leakage severity, access conditions, water pressure, treatment area, structural condition and the required injection material. A site assessment is needed to determine the scope of work and provide an accurate estimate.
POLYJET uses proprietary polyurethane resins, acrylate gels and mineral injection grouts for different sealing and groundwater-control conditions. Depending on the project requirements, engineers may select PolyJet GT®, PolyJet Fast AG®, PolyJet Fast PU® or PolyJet MF05® based on water pressure, crack geometry, required reaction time and structural objectives.
Crack injection is used to seal individual cracks and joints within a structure. Curtain grouting creates a broader waterproof barrier behind or around the structure where water ingress cannot be controlled through local crack sealing alone.
Yes. Injection systems can be designed for structures exposed to high groundwater pressure, but the material, injection pressure and treatment sequence must be selected according to the hydrogeological and structural conditions of the site.
