PU Injection Grouting for concrete & subsoil application

Jul 01, 2021

Every RCC building and structure is designed for a specific type of loading and different types of environments. Hence after some time these structures need periodic maintenance and strengthening. Hence it is essential to restore the strength of concrete structures by assessing and restoring damages and defects. Different defects might occur, but one common problem is cracks and fall of plaster in the core section of the concrete. The requirement herein is the structural strengthening with PU injection grouting. It is used for sealing the cracks, open joints, voids, or honeycombs, in concrete or masonry structural members. This is done under pressure with a grout material that cures in place to produce the desired results like restore structural integrity, prevent water ingress and sealing the crack.


PU Injection grouting is necessary for the following purposes:

  1. To restore damaged concrete surfaces
  2. To waterproof and strengthen tunnel linings/structures
  3. To avoid seepage of water in stone masonries
  4. Settlement of foundation
  5. Repair and retrofit unreinforced masonry

Depending on the size of the crack, and the result required, various types of products are utilized. MC- Injekt 2700/ 2700 L IN are two such injection grouting manufactured by MC-Bauchemie. These are 2 component injection PU based Duromer resins that cure a waterproof resin body. These injection resins can be injected into subsoil with and without water stress. They fulfill high water hygienic requirements., in contact or when mixed with water, the duromer resins are converted into solid and closed-cell foam.

Features of MC-Injekt 2700 / 2700 L IN

MC-Injekt 2700 / 2700 L IN  are force transmitting Injection resins used for concrete, brickwork and subsoil, its features includes;

Applications of MC- Injekt 2700/ 2700 L IN

Before each application, the injectivity of the structure or the subsoil must be checked and an injection concept is to be defined. Its application area includes;

  • Sealing and reinforcing cavities and cracks structures made of concrete, masonry and natural stone in building construction, hydraulic engineering and general civil engineering
  • Sealing of construction pit enclosures
  • Solidification of subsoil in special foundation engineering
  • Increasing the load capacity of subsoil under floor slabs and foundations
  • Sealing of rigid joints in structures
