Injection grouting is a straightforward process used to fill cracks or voids and concrete or structural members to repair cracks or strengthen damaged components. The grout is a flowable material which should have negligible shrinkage and is applied in the cracks or voids utilizing pressure. It should remain stable without cracking or crumbling. Today, there are a handful of different types of grout injection material commonly used during concrete or masonry repair work. The key is selecting the right type of grout injection material based upon what original material needs to be fixed or replaced.

Polyurethane

The first popular option is polyurethane grout.
In most cases polyurethane comes in the form of a resin. It has proven to be an effective method of improving the mechanical and sealing properties of both soil and rock environments. Polyurethane is a particularly useful grout injection material when treating water retaining structures. Polyurethane is extremely versatile which means it is important to focus on specific characteristics which are desirable. For example, polyurethane resin can provide a soft foam, rigid foam, semi rigid resin, and high-strength resin. This allows for a range of different flexibilities and strengths. All polyurethane resins have a low viscosity to ensure it penetrates into my new cracks and provides complete leak proof results. It also provides long-lasting results because the hardened phone and it creates features excellent adhesiveness on both wet and dry surfaces.

Acrylic

Another popular grout injection material is acrylic. Acrylic grout is typically a two component mixture which forms a gel like substance which offers excellent elasticity, swelling power, and durability. Acrylic is often found when using curtain grouting injection. This method is often found in tunnels, subways, building basements, and other areas which exhibit the ground settling affect and water stop affect. One thing to keep in mind is acrylic injection grouts may have some shrinkage which will alter resistance to corrosion of steel and dynamic loads.

Epoxy

The final popular category of grout injection material is Epoxy see. Epoxy based grouts possess non-shrinking characteristics. It is effective in sealing cracks and does an excellent job bonding with nearly every building material. Epoxy also features good chemical resistance. Epoxy is typically defined by how viscous the injection make sure will be. There is often separate epoxy blends for grouting underwater or when a particularly elastic application is required. While shrinkage is minimal to nonexistent, epoxy tends to have a slower hardening process than other types of grout injection material.

Carbon Fiber Sheets Can Enhance Results

Regardless of what type of grout injection material is used it is beneficial to consider using a carbon fiber sheet when applicable. Carbon fiber sheets offer excellent tensile strength and elasticity. They are often used to repair and strengthen concrete structures, particularly chimneys, beams, and slabs of buildings/titles. Carbon fiber sheets have been shown to be a much better alternative than steel concrete or steel sheets.
