Construction Company Solves Drying Issues with Polygon

A construction company building a new school in London was having issues drying screed and walls to the optimum level. Contractors must be certain that the walls and floors in any new construction have been dried properly; failure to do this could mean that, in time flooring may lift and mould could develop. Ultimately, this could require the contractor to revisit the job to do remedial work, costing them and the client time, money and loss of reputation.

Problem

The client was on a tight deadline to complete the project and was having problems drying the walls and screed. Concerned about the repercussions if they were to prematurely lay the final floor and wall finishes, they needed the building to be surveyed to search for causes of leaks and penetration points.

Solution

Polygon deployed an engineer within a day to conduct a full onsite building survey, which identified areas of concern. Relative Humidity (RH) readings were conducted, and they confirmed client concerns that the screed had not dried properly. Polygon then created and executed a bespoke solution to target the required areas.

Polygon has an extensive portfolio, so we were able to arrange for the delivery of all required equipment to the site quickly. To create the correct environment, six dehumidifiers were installed along with a 170 kW heater and two 65 kW heaters. Polygon’s engineers also used specialist equipment that plugged into the roof membrane and pulled out all moisture using a high vacuum pump.

Noticeable reductions were witnessed in moisture levels within a week, and equipment remained on site for 3 months. Polygon conducted weekly maintenance visits where the unit was checked and readings were taken to ensure that the environment was being controlled to the exact requirements.
