What is concrete injection?

Despite its sturdiness and longevity, concrete isn’t invincible and will eventually give way to the damage it has accumulated. This damage usually manifests itself as a crack; if ignored, this can lead to even greater damage to the concrete.

This is where concrete injections come in. Concrete injection is a process that avoids completely replacing concrete by simply injecting a special formula into damaged areas to fill and strengthen them. Let’s break down the common uses of concrete injections and look at the general process of applying them.

Uses

Concrete injections are most commonly used for concrete structures that would be too expensive or time-consuming to fully replace, enabling you to avoid arduous processes such as digging or draining. Foundations in buildings, for example, are not the most viable choice for a full replacement when the damage shows itself. Fortunately, concrete injections can quickly and cheaply resolve the issue, without having to start afresh.

It is worth noting that concrete injections are not permanent solutions and that new cracks will appear in close proximity to the original if you don’t address the underlying cause.

The process

Although not quite as quick and easy as a flu jab, concrete injections are still relatively simple. Once inlet and ventilation ports have been established along the crack in the concrete Swindon or elsewhere, concrete filler is inserted, spreading and solidifying within the crack.

In some cases, such as repairing cracks in concrete floors, foam injections are also used. These are injected under the slab in liquid form, expanding to fill voids and raise the concrete. This is done by drilling small holes into the concrete to reach through to the underside, with the foam hardening almost instantly. More information on the foam (polyurethane) can be found here.

In terms of causes of concrete damage to be aware of, there isn’t much you can do to mitigate them, as they are usually invisible, inaccessible, and insidious. Soil expanding in concrete in Swindon due to moisture retention, for example, is not something you can easily prevent, but it is something you can counteract.
