Injectable grout, or injectable foam, is a technology that allows Masonry Restoration to stop active leaks. These products are a practical, effective and affordable solution for structural waterproofing when digging the exterior is not an option.
Polyurethane injection grouting is a service and a technique that has been around for decades as a tool in the ever expanding arsenal of waterproofing products. Grout, or foam, is injected either into a crack or to the other side of the wall. They interact with water and it expands many times in volume to stop the water. Masonry Restoration has been extremely successful with grout injections and foam injections as a means of addressing our customers’ water issues. Grout injection is a beneficial choice to stop leaks from numerous angles. By being able to target the low-pressure injection into the specific area needed, we can use it to level out the cracks and problem-areas to make the site a more even surface. This is valuable not just structurally, but cosmetically, as grout injection does not affect the look of what it is applied to – so you never have to worry about mess left behind or odd patches that stick out.
Injection grouting also helps ensure that leaks are not just stopped now, but through the foreseeable future. It allows for greater overall durability with the building it is applied to by stopping moisture from filtering down. In some cases it can also add extra strength and durability long-term.
Because grout expands to fit where it is injected, it’s essentially like you have custom molds made right for your site. These injections then stand the test of time because they do not crack, crumble, or break, even under pressure. They can typically stand up to tremendous and surprising water immersion and rain exposures as well.
Some Different Varieties of Injection Grouts:
There are several different types of grouting that can be used depending on the specific job. This means that the product and experience you get are always tailored to fit you and your structure’s individual needs.
Fiber reinforced injection grouting can be extremely useful when extra strengthening is necessary. This form is specially created with steel, polypropylene, or glass fibers in the mixture to keep the buildings stable for years to come. It requires adept extra care to keep the fibers together and in place during application for the greatest success.
Polymer injection grouting is made with polymers like epoxy, acrylic resins, polyester, and more. It can come blends like liquid resin content, a curing agent/hardener, and aggregate/dry filler, or a mixture of just a curing agent/hardener and aggregate/dry fillers.
Injection Packers is often the choice for repairing masonry or concrete structures. It uses large amounts of water and cement so that it can be effectively injected.
