CPR Services is your leading polyurethane concrete injection service in Sydney. Our 150+ years of combined experience in concrete crack repairs, including epoxy injection, places us at the forefront of polyurethane injection technologies, equipment and methods. Epoxy injection is typically performed on dry substrates compared to polyurethane injection, which works very well on wet and actively leaking substrates. Epoxy injection is the preferred method when structural crack repair is desired.
ARDEX RA 146 - Epoxy gel for injection of concrete cracks on the blind side - 470 ml is a great choice for repair of structural cracks of medium to large cracks. Pressure injection for cracks from 6 mm to 10 mm can be done with 100% solids, solvent-free system with low VOC content Sikadur 52 Consumption Calculator Normal - Double Cartridge Pack of 450 ml. The ARDEX injection range for concrete crack repair and uses a high-strength, fast-setting two-part system to repair concrete damage from fine cracks to structural repairs. These products are ideal for repairing holes, chips and cracks in concrete, in both internal and external situations where heavy vehicle traffic is anticipated.
Once cured, the repaired concrete cracks will be two to three times stronger than the original concrete, ensuring a durable and long-lasting crack repair solution. Super Low Viscosity Epoxy Structural Concrete Crack Injection is a great choice for foundation crack repair products that are available in easy-to-use starter kits, making learning the various components much easier for anyone new to crack repair. For experienced contractors, our products are available for individual purchase. Fortunately, there is an easy way to permanently repair such cracks without the need for costly and annoying digging or draining tiles.
Cracks in poured foundations can be repaired by low-pressure injection of an epoxy or polyurethane foam material. For the repair of cracks in the concrete floor, there are certain epoxy and polyurea materials, suitable for such repairs of slabs. Let's compare some of the main characteristics of each type of crack injection, describing their strengths and their recommended range of applications. The use of polyurethane, sometimes referred to as urethane or grout: concrete crack injection is very popular due to its versatility of low viscosity polyurethane injection resins for leakage sealing, making it the most effective leaking crack repair solution.
However, please note that the type of epoxy or polyurethane used and the time required for injection will vary with each job depending on the width of the crack, the thickness of the wall and other conditions. Epoxy crack injection is typically used in horizontal, vertical and overhead cracks where conventional repair methods cannot penetrate or are too cost prohibitive. Premium polyurethane kits are specially designed to be easy to use, but still deliver professional and permanent repair results to prevent leakage of cracks and waterproof your base. Alternatively, if the crack is not structural, a hydrophilic polyurethane resin of low viscosity would achieve the best result.
Epoxies and polyurethanes are chemical resins with different reaction profiles and physical properties. The components are mixed in the static mixer of the injection pump applicator immediately before the injection of cracks. Using low-pressure crack injection, foundation and basement crack repair kits seal basement cracks from the inside, eliminating the need to dig the ground from the outside of the foundation. In some cases, structural cracks may be too wet and cannot dry out, in such cases, a moisture-tolerant resin is often used.
It also cannot be used if water leaks from a crack between the wall seam and the slab, which indicates a problem in the water table. The injection of polyurethane cracks is often done at higher pressures to move the expanding foam through the cracks with special injection pumps and packers installed in the drilled holes. At higher pressures, the liquid has enough force to overcome gravity and climb up the crack without filling the back, which is normally narrower than the front of the crack. ARDEX RA 144 - Low Viscosity Structural Concrete Crack Injection Epoxy - 470 ml is a great choice for pressure injection and repair of structural cracks with gravity feed in horizontal concrete, masonry for cracks from 3 mm to 6 mm with epoxy resin binder for epoxy mortar patches and surface coating interior by adding added shear fracture repairs indoors and outdoors.
