Construction Film
A high performance under slab vapor retarders designed to retard moisture migration through concrete slabs-on-grade. A vapor retarder as defined by ASTM E- 1745 is a material or construction that impedes the transmission of water vapor under specified conditions. Typical construction films are made of low-grade polyethylene resin and recycled materials that causing their strength and permeability to be inconsistent. They are good for temporary applications but are not designed to provide ongoing protection from unwanted moisture. With out the proper vapor retarder excessive moisture will effect the floor finishes causing the adhesives to break down, warping or peeling, rotting of carpet, buckling and decay of wood floors, as well as offensive odors and fungi growth.
Advantages
- High tensile strength and puncture resistance
- Low moisture vapor permeability
- Resistance to decay top of page

Bulk Bags top of page
One of more versatile flexible packages on the market, bulk bags often are used to transport contaminated waste, soil, and debris to landfills served by rail. In recent years the use of bulk bags have expanded to include temporary dams, for either stream diversion or onsite exclusion zones. When filled with sand a 3’ x 3’ x3’ bulk bags provides an efficient barrier. When stacked and faced with an impermeable liner, the bulk bag dam is a safe and cost effective alternative to inflatable structures. Bulk bag dams can be rapidly deployed and the height can be adjusted to site-specific conditions. Contact us for more information on applications, pricing and availability.
