W.R. Meadows has unveiled a weather-coated, permanently bonded, semi-flexible, vaporproofing and waterproofing membrane designed to stop moisture migration in footings, concrete floors and structural slabs.

The patented Premoulded Membrane Vapor Seal with Plasmatic Core, or PMPC, is billed as an affordable, easy-to-install system for horizontal applications.

A new seven-ply membrane by W.R. Meadows is engineered to prevent water mitigation in footings, concrete floors and structural slabs.

“It exceeds industry standards for puncture resistance, tensile strength, and offers the lowest perm rating in the industry, less than 0.002 perms,” Russ Snow, Building Science Specialist at W. R. Meadows, said in a release.

How it Works

PMPC is composed of “an exclusive plasmatic core suspended mid-point between two layers of a homogeneous, bituminous material,” the company says.

The product conforms to ASTM E 1998-93 and resists jobsite puncturing, the manufacturer says.

The membrane is then sealed under heat and pressure between liners of asphalt-infused felt and a glass-mat liner. It then prevents water migration in footings, concrete floors, and structural slabs when applied properly.

An asphalt weather coat is then applied to the glass-mat liner and covered with a polyethylene anti-stick sheet.

A built-in protection course resists jobsite puncturing and the abrasive action of concrete placement, according to W.R. Meadows. The product conforms to ASTM E 1998-93.
