Injection Grouting
Cement based injection grouting
Cementitious grouting is a process in which a fluid cementitious grout is pumped under pressure to fill forms, voids, and cracks .
Polyurethane (PU) injection grouting
PU grouting is a specialised technique that involves the injection of expanding polyurethane to stop any water flowing through cracks or to fill voids under slabs, concrete joints or behind concrete walls and joints.
Liquid Epoxy injection grouting
Epoxy Injection Grouting is a method of repairing cracks or honeycomb in concrete structures. Epoxy Grouting is generally used for building strengthening e.g. Column, Beam, Pillar, RCC Slab, etc.
Acrylic injection grouting
Acrylic based resins can waterproof leaks and seal even the smallest cracks .
What is injection grouting ?
Injection grouting is a specialized technique used to repair cracks, joints, and voids in concrete, masonry, and other structures by injecting grout or other specialized materials into the affected areas.
Here’s some related knowledge:
Purpose
Injection grouting is primarily used to seal cracks and joints to prevent water ingress, reinforce structures, and stabilize soil or rock formations.
Materials
Various materials can be used for injection grouting, including cement-based grouts, epoxy resins, polyurethane resins, and acrylic-based grouts. The choice of material depends on factors such as the type of substrate, the size and nature of the crack, and the desired outcome.
Process
The injection grouting process typically involves drilling holes into the substrate, injecting the grout under pressure using specialized equipment, and allowing the grout to cure and form a tight seal. The process may vary depending on the specific application and the type of material being used.
Types of injection grouting
– Crack Injection : Used to fill and seal cracks in concrete or masonry structures.
– Void Filling : Used to fill voids or cavities in soil or rock formations to improve stability.
– Compaction Grouting : Used to improve the bearing capacity of soil by injecting grout under pressure to densify loose or weak soil.
Applications
Injection grouting is commonly used in various industries and applications, including:
– Waterproofing basements, tunnels, and underground structures.
– Repairing cracks in concrete structures such as bridges, dams, and buildings.
– Stabilizing soil or rock formations in construction and mining projects.
– Strengthening foundations and retaining walls.
Benefits
Injection grouting offers several benefits, including:
– Provides a long-lasting and durable solution for waterproofing and structural repairs.
– Can be applied to both horizontal and vertical surfaces.
– Minimizes disruption to the structure and surrounding areas compared to traditional repair methods.
– Offers versatility in terms of material selection and application techniques.
Overall,
injection grouting is a versatile and effective solution for addressing a wide range of waterproofing and structural repair challenges in construction and civil engineering projects.
