Injection Grouting Services

What is Injection Grouting ?

Injection grouting is the method of filling 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 strengthening a structure and preventing water ingress.

Applications of injection grouting system

  • Concrete surfaces
  • Tunnel linings
  • Stone masonries
  • Dam
  • Settlement of foundation
  • Masonry
  • Underground structure

Types of Grouting

Based on the materials used for grouting, it is classified into many types. Different grout materials have other characteristics; choosing the right type for your leak repair is important. The available grout options are as follows:

Cementitious Grouting

This type of grouting uses traditional grouting material like cement and water, along with admixtures and additives for residential applications. If this is used for quarry, slate, or natural stone tiles, grout stains are possible on the surface.

Epoxy Resins

This type of grouting contains resins and hardener that makes it less porous than cementitious grouting. It adheres well to metal, concrete, and ceramics but not on wet surfaces. It is vital, resistant to chemicals, and can be used ideally for kitchen areas.

Acrylic Resins

This type of grouting forms a permanent gel with high tear strength and is most suitable to use for architectural coatings and product finishes.

Polyurethane

Polyurethane has low viscosity and allows it to flow through even tiny cracks comfortably. After injecting this PU, it retains its flexibility while keeping the gaps sealed. So, this type of grouting is efficient in protecting the structure against most water damages at a low cost.
