Cold weather placement of concrete is a tough job by anybody's standards- particularly when the temperature drops to the zero mark or below, and life is made even more miserable by snow, sleet and soft ground conditions that bog down mixer trucks. However, a concrete pump can do much to take some of the hard work, inconvenience and hazards out of winter placement of concrete. With modern technology, it is now possible to pump concrete with proper winter additives in almost any weather. Pumping can eliminate the necessity for scaffolding, ramps and buggies, as well as many of the hazardous aspects of working in inclement weather and on ice-coated structurals. For example, with a concrete pump most of the concrete placing operation can be conducted in relative comfort and warmth. Contractors often build a "dog house" around the pump- which would be situated adjacent to a hard-surface roadway where mixer trucks can easily service it. Thus the pump operator works in comparative comfort and safety, away from the wind and inclement weather. Unlike other methods a hose can be run through any six-inch opening and the rest of the building can be sealed off completely. Any other system will require considerable open areas with subsequent discomfort for the workmen. Relocation of pipes and hoses is a relatively simple matter, and they can be positioned in such a fashion that they can be simply valved to distribute the flow.
