N E T SLAB/HORIZONTAL Poly Burlap Curing Blanket Poly Burlap curing blankets are a combination of 10 oz. burlap and 5 mil white opaque poly. The 5 mil polyethylene is extruded onto the 10 oz. burlap. The result is a lightweight water curing blanket that can be used over and over again. The burlap layer distributes the water evenly over the covered surface, while the white opaque poly reflects the intense rays of sun. This way, the concrete is allowed to cure properly. After each use, expose burlap side to the sun or air. The burlap will be ready to use again quickly. Meets AASHTO M-182, Class II, and ASTM C-171 specifications when chemical cures are not allowed. No. Size Wt (lbs) MC 10100CL 10' x 100' 76.0 CURING BLANKETS Insulated Curing Blanket Cold weather curing of concrete is best done with thermal blankets. Available with reinforced polyethylene, curing blankets are filled with layers of polypropylene foam for un-paralleled "R" value. Closed-cell polypropylene foam won't absorb water. Since the core stays dry, the blanket maintains its thermal conductivity so concrete can achieve the greatest possible strength. A dry core also makes for a lighter blanket, and that in turn speeds placement, reducing costs. Curing blankets resist tears and punctures so they can be reused again and again. Between uses the blankets are easily folded for storage and transport.

Burlap should be rinsed thoroughly before placing. Care should be taken to ensure proper lapping and that all concrete edges are covered. Keep continuously wet. Burlap may also be used to roughen fresh concrete surfaces by wet dragging. Standard weight 10 oz. No. Size Wt (lbs) CT BURLAP 40" x 300' approx. 80.0 approx. CT BS 14" x 26" bag, 25/Bndl 0.72/ea.
