Damp proofing is an important part of any building project. It involves the application of foam, usually polyurethane, to damp walls and ceilings so that moisture cannot get through damp proofing. It is typically applied to commercial projects where it is needed to prevent rising damp from reaching the interior of the building. If left unnoticed, it can spread quickly to surrounding areas, causing health problems and structural damage. Dampproofing is particularly important in domestic situations, as it can help to reduce dampness in the home and prevent it from spreading.
Damp Proofing Injection
Damp proofing injection mould is used for damp proofing products where a moulded impression of the area to be treated is produced by the injection equipment before the concrete is poured. The mould is normally made out of PVC so that it can be reused after the concrete has been poured. This is a cheaper alternative to other forms of damp proofing, as the resin is not required and because there is no need for the mortar to be embedded into the concrete. Another advantage of using the PVC mould is that it provides the building with a consistent external finish. With this method, a pattern of mould lines can be recognised, which can help with visual appeal and create a better-looking surface for the finished project.
Another common application of damp proofing injection mould is when exterior concrete is sprayed with a water-based damp proofing cream. The cream is generally sprayed onto the concrete after the wall has been formed, and before it is cured with a special tool that makes sure the cream will not seep into the interior of the wall. If this were to happen, it would prevent the wall from being waterproof and could cause cracking. It is important to note that it is possible for the cream to be removed by simple wiping with a damp cloth once it has been sprayed onto the wall.
