Almost all properties, whether residential, commercial, or industrial, are prone to water damage at least once in their lives. The improper drainage system, enormous loads brought on by the movement of machinery and vehicles, and regular wear and tear are the main causes of building cracks. Without extensive remodelling, PU injection can effectively repair these fissures.

After installing tiles, gaps, cracks, and seams are filled with grout, which is a mixture of cement, sand, water, and chemicals. The distinction between grout and concrete may be unclear to you. There is a difference to be made, of course. There needs to be a differentiation, of course. Gravel and other materials are mixed into the concrete to increase its strength and roughness.  At the same time, the grout filler is thinner (made of fine sand) and of more spreadable nature.

Grouting is a sophisticated method of injecting grout material into cracks, voids, joints, and cavities. Grouting is primarily used to reinforce the formation, decrease the amount of water passing through it, and repair flaws like fractures in masonry and concrete constructions. The following are the different grouting needs that are taken into account:

​

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:

1. 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.

2. 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.

3. 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.

4. 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.

PU INJECTION GROUTING:

This is one of the waterproofing techniques used to prevent water intrusion through the voids and cracks in the concrete structure. This uses the expanding injected polyurethane in solving the leakage and seepage issues to a greater extent and is effective when applied on the lower side of the ceiling.
