Flood peril for construction sites across the UK

As Storm Christoph is set to bring flooding to many parts of the UK, moisture and temperature control specialists Aggreko warn affected construction sites could face further damage if the drying process is not carried out effectively.

Posing significant costs for materials damage and disaster recovery, the amber weather warning issued for parts of the North of England and the Midlands will likely cause flooding to construction sites, adding costly delays to existing projects.

According to Aggreko, the incorrect removal of moisture onsite could exacerbate this damage and lead to further costs and delays. Ryan Stanley, Moisture Control Sales and Product Manager Northern Europe at Aggreko, is warning construction managers and directors that a strategic drying and dehumidification process is needed to resolve a moisture problem completely.

“Flooding can have a disastrous immediate effect on a construction site, damaging building materials and plant, not to mention the delays caused to a project’s progress,” he says. “However, when the moisture from flooding is not removed entirely after an incident, the lasting effects of the damage can cause issues of damp and even mould long into a building’s life. Costly repairs thereafter, and even damaged reputation for the firms involved in its construction, are long term effects that can be easily avoided with correct moisture removal protocol.”

As discussed in Aggreko’s recent guide – The Hidden Cost of Humidity on Site – the drying process must be carried out in a controlled manner to avoid further damage and alleviate the moisture problem once and for all. By heating a space, circulating the air and removing the moisture with dehumidifiers, all of the water molecules can be drawn out into the air and be removed effectively from the site. This three-step process must be done in a controlled way, as removing moisture too quickly can also damage on-site materials or the building’s fabric, resulting in further cost and delays.

Ryan adds: “It is a common misconception after heavy rain or a flood that simply heating a space vigorously will dry it out. While it may look dry initially, the water molecules drawn into the air by the heat will simply absorb back into the materials and building fabric, continuing to cause issues. By following this three-step model and monitoring the conditions in the room, a gradual and complete removal of moisture will ensure any flooding does not cause persistent and costly issues for construction professionals.”
