Injection Grouting is a construction technique used to fill voids or cracks in structures, such as concrete or soil. This process involves injecting a fluid material, often a mixture of cement or resin, into the targeted area under pressure. The injected material hardens, providing stability and preventing further damage. This method is commonly employed in foundation repair, waterproofing, and soil stabilization. By sealing gaps and reinforcing weak areas, injection grouting helps improve the overall integrity of buildings and infrastructure, making it a vital tool in civil engineering and construction projects.
