Epoxy Injection is the process of repairing or sealing cracks in structural concrete members such as beam, column, slab, foundation, basement wall, etc. VIP members get additional benefits. How can we use magnetic levitation method in civil engineering? Cured epoxy typically has a tensile strength of around 7000 psi greater than that of concrete at around 300-700 psi. Installing the Ports. Procedure for Epoxy Injection Grouting in Concrete Structures: Surface preparation is the first step in repair of cracks in concrete. Equipment required for epoxy based injection grouting, procedure for grouting will be discussed here. Before injection commences, where we effectively glue the crack together, it is important to understand: how the crack came about in the first instance; if there is a need for structural repair; and whether the … Crack Injection can be Grouped into Two Subcategories. Most of the concrete cracks are related to shrinkage, heat, wrong joint placements, over stress and loading conditions and movements caused by external factors. Epoxy Injection Grouting of Cracks in Structures, Pre-Concrete Checks for Reinforcement and Its Cover, Testing of Concrete Cores for Strength – Sampling and Procedure. Pressure of 3.5 to 7 kg /cm2 is normally used. Epoxy formulation is injected from the bottom most pipe. Epoxy crack injections are an effective and incredibly reliable concrete crack repair method, used solely for the purpose of repairing poured concrete foundation cracks in a structural sense, to fix basement leaks, and to prevent poured concrete foundation cracks from leaking in the future. Product #301SC Slow Cure Injection Resin Low Mod is a longer Potlife version of Product #301. Cracks in concrete elements (beams, slabs, columns, walls, etc) undermine the monolithic character and strength of the structural element. Example Included. These products are designed to work well in a wet environments. The structural repair of cracks in poured concrete structures (such as bridges, columns and roads) utilizing epoxy injection has been successfully used for over 40 years. Sealing Leaks in Carribean Sea Aquarium. This extra area is … The injection process used is also known as chemical grouting  —  referring to the gels, resins and foams as chemical grouts. High-modulus, high-strength, structural, non-abrasive, smooth epoxy paste adhesive Sikadur®-31 Hi-Mod Gel. Types of Foundation for Buildings and their Uses [PDF], Methods of Rainwater Harvesting [PDF]: Components, Transport, and Storage, Compressive Strength of Concrete -Cube Test [PDF], Procedure, Results, Standard Size of Rooms in Residential Building and their Locations, 16 Types of Heavy Equipment Used in Construction, Sardar Patel Stadium: Construction Features of the Largest Cricket Stadium in the World, Tower Bridge: Construction Features of the World-Famous Symbol of London, How to Design Reinforced Concrete Beam for Shear? I. The ARDEX Concrete Crack Repair & Injection Range uses a high strength, rapid setting two-part system to repair concrete damage from hairline cracks right through to structural repairs. Structural cracks and cracks with larger depth must not be repaired using epoxy. References 1. Epoxy Injection For Concrete Crack Repair Concrete cracks are repaired using different techniques and methods, such as epoxy injection depending on how wide, long and/or deep the crack is.
