PU Grouting or sometimes called Polyurethane Injection is a widely used waterproofing method of injecting a polyurethane mixture into the cracks of a structure to stop water leakage. This mixture reacts upon contact and expands gradually to fill and seal any cracks, gaps or voids.
It is used when common structural issues such as cracks, holes, leaks or water damages are identified. It is typically applied on areas such as external facades, swimming pools, sewer lines, concrete walls & floors. PU injection is a great method that can be used to repair damages to residential, commercial or industrial structures due to its versatility and ease of application.
The damaged site is carefully inspected by a professional to determine the suitability for PU Grouting.
Upon confirmation that the structure is suitable and the damage can be repaired using this method, the work process begins. Small holes are drilled into the site in order to clean and repair the damaged site.
Once the holes have been formed, a PU grouting nozzle injection packer will be inserted and properly secured. A high-pressure stream of clean water will be injected to clear the repair site of debris.
After the cleaning process, the polyurethane mixture will be injected into the hole. The site will be carefully sealed to ensure the mixture will not seep out and damage the exterior.
After the grouting procedure is complete, the technician will perform checks to ensure the cracks have been properly repaired. The injection site will then be sealed with a cement-based material. The repair site will also be properly cleaned of any liquids or debris from the procedure.
Once the cement has properly set, additional waterproofing material will be applied on the injection site to ensure full protection from water leakage.
