In Glenview, Illinois, a home builder used a party tent for cold weather concreting of a townhouse development. The tent is stronger than the builder's old site-built enclosure because it's a heavier material and comes in mostly one piece. Also, the supplier erected the tent so the builder's crew could do other work. To see if party tents are cost-effective for winter concreting in your area, simply call some local suppliers and see what services and prices they quote.
