construction massachusetts
Many construction massachusetts fail to account for the effect of ambient conditions on their project timelines and budgets. For instance, high relative humidity will cause materials and finishes such as concrete or plaster to cure much more slowly than expected - if at all. This is not good news as missing project milestones, idle time and expensive reworks can create significant financial and operational problems for a project manager who already has enough on his or her plate.
The good news is that these problems can be avoided at a fraction of the potential consequential cost of suffering humidity related delays. Using the correct dehumidifiers in these situations can really make a difference to the progress of any construction massachusetts project. Indeed, I have helped many construction-related businesses to understand the value of spending a little of their project budget to improve quality and efficiency by creating favourable conditions that can keep project timelines on track and minimise costly reworking. Construction and civil engineering companies, flooring contractors, plasterers, painters and shopfitters have all benefitted from this advice on a variety of projects from house-building to major infrastructure jobs.
Unfortunately, many people in the construction massachusetts and related industries do not fully understand the requirements and so waste money on ineffectual solutions. Equally unfortunate is the lack of understanding - and sometimes outright misdirection - prevalent among many equipment hire companies. Please allow me to explain.
Dehumidifiers generally fall into one of two categories, i.e. refrigerant or dessicant units. Refrigerant dehumidifiers are the type typically marketed in a hire brochure as a 'builders dehumidifier' or 'building dryer'. These small units work on the same principle as the pipework found on the back of a household refrigerator. Warm humid air is drawn across a cold surface extracting moisture from the air in the form of condensation. This principle is reasonably effective so long as the air is warm. During winter months this process is much less efficient due to the cooler temperatures encountered on a construction site. It is at this point that an inexperienced, or ethically challenged, hire provider will suggest adding a heater to 'help things along'.
Usually a direct-fired propane or paraffin heater is added which actually introduces moisture into the area via the fumes from the burnt fuel. This additional moisture is then captured by the refrigerant dehumidifier and so gives the appearance of a more efficient solution. A dessicant dehumidifier on the other hand extracts moisture from the air via dessicant material and expels it from the area to be dried using ducting. The relative humidity in the area is reduced until it is lower than that outside and essentially turns the air into a sponge. The dried air creates an environment whereby the moisture is 'sucked' from the concrete, plaster etc. through the process of capillary action. Moist air is continuously expelled, and dry air introduced, until the required level of drying has been achieved. This is a much more efficient method of drying out walls, sub-floors etc. and its effectiveness will not be reduced by cold temperatures.
