DMX FlexTrim is available for sealing cut edges in the membrane where the flat panel has had to be trimmed off. Poured concrete (the most common type of foundation in Chicagland) is formed (casted) onsite. Any concrete or masonry foundation walls "that retain earth and enclose interior spaces and floors below grade shall be dampproofed from the top of the footing to the finished grade." The concrete is then poured and creates a bond with the membrane as it cures. In the context of below-grade protection, dampproofing refers to treating a surface to resist the passage of moisture in the absence of hydrostatic conditions. So, even though water vapor can get through the Fox Block foam, the Blocks control moisture accumulation. Block & Wall® is low VOC, non-toxic, and environmentally friendly.

Stopping the accumulation of moisture is essential to preventing the growth of mold within the wall system. The product can be used for both above-grade and below-grade applications. The BEHR 5 gal. Allow to dry overnight or for a minimum of 12 hours between coats. Condensation is when water vapor (moisture in the air) changes into liquid water.

In 1900, American Harmon S. Palmerpatented the first hollow concrete block design. Ultimately, Fox Blocks create an airtight building envelope that limits thermal convection and moisture intrusion through the above-grade walls. Self-adhering membrane for below grade ICF foundations. Use with 1¼ inch concrete nails for poured or concrete block foundations. The wet soil is kept away from the foundation walls and if any moisture does find its way past the membrane, it is carried to the foundation drain by the air gap drainage path.
