Cracks in a concrete building can cause a lot of problems if left unattended, including letting water into the structure, resulting in deterioration of the concrete and rusting of the reinforcement steel.
Therefore, it is essential that concrete repair specialists are called in as soon as cracks are detected to prevent them from worsening and to keep the structure as sound as possible.
This is particularly the case when the crack is wider than a quarter of an inch thick or there are many gaps to be fixed.
One of the best ways to fill the voids is with pressure grouting. This works by injecting cementitious and resin-based grouts under controlled pressure into the concrete.
This will flood all the gaps in the walls, filling even the ones that had not yet been detected.
Pressure grouting is, therefore, a great choice when it is difficult to access the cracks on structures or when they are not easily visible.
This is why it is often used for car parks, basements, tunnels, sewers, and bridges. Tall buildings, whether made of concrete or brick, also frequently need voids to be filled, which is why building repair experts typically use pressure grouting to get the job done.
The materials used to fill the gaps will depend on the type of structure it is and what it is originally made of. Traditional materials are most often used, so that it is not apparent to the naked eye that cracks have been filled. Instead, the repairs should blend seamlessly in with the rest of the building and remain undetectable.
Work like this enables these buildings and structures to be used for longer instead of having to be demolished and replaced with newer models.
