Drying Solutions for Construction Sites
During construction work and building renovation, there are a multitude of wet processes that require complete drying before work can progress. Concreting, plastering, screeding and painting are all processes that need to dry fully before further work can continue. A construction dehumidifier speeds up this drying process, helping to reduce downtime on site and shorten a project’s overall timescale.
Construction dehumidifiers are commonly used as site drying equipment for refurbishment projects, new builds and property renovations where controlled drying is required before final finishes can be applied.
How Do Construction Dehumidifiers Work?
Construction dehumidifiers work by quickly drying out areas that are undergoing work. They accelerate the drying rate of wet processes such as plaster, concrete and screed, helping to ensure that the quality of the work and final finish is not compromised.
Construction dehumidifiers help concrete floors settle at the correct moisture level before coverings are laid, can reduce the risk of cracking or distortion in cement-based materials, and help prevent paint failure caused by excess moisture. They can also be used as flood drying dehumidifiers on construction sites that have become wet due to leaks or bad weather.
Dehumidifiers work by pulling in humid air, collecting the water from this air and releasing fresh, dry air back out. This dries out the environment, making it harder for mildew and mould to form and assists with surface drying across walls, floors and structural materials.
Check out our drying calculator for help deciding on the correct size construction dehumidifier for your projects, based on site conditions and moisture load.
