What Is the Difference Between Cold Fluid-Applied Waterproofing and Damp-Proofing?
W. R. Meadows » Waterproofing
by Denise Dorman

The art of waterproofing started 13,000 years ago, developed to become the third trade after carpentry and masonry. As we became an agrarian society, farmers had to protect their grain from moisture and rotting during the cold months to prevent starvation. This Neolithic Era also brought boat-building and sea voyages into play to foment trading, so they devised a bitumen made from the surface of peat bogs, which wasn’t unlike the asphalt we use today. And then there were the Egyptians, whose Pyramids of Giza tombs were pristine despite the flooding of the nearby Nile River, so even in 3600 B ..read more

In this application, PRECON® was used as a pre-placed/blindside waterproofing solution for a terminal rail station at the Dallas/Fort Worth International Airport. Corgan Associated selected PRECON for the 240,000 sq ft. project because it met physical requirements while also being cost effective and easy to apply. PRECON is a composite sheet membrane comprised of a non-woven fabric, elastomeric membrane, and W. R. MEADOWS’ exclusive, patented plasmatic core (U.S. Patent No. 7,179,761). It is used as a blindside membrane in vertical applications where access to the positive side is limited. Al ..read more

The MEL-DRAIN TOTAL-DRAIN sheet drain system combines any regular MEL-DRAIN sheet drain section with the unique TOTAL-DRAIN section. In the TOTAL-DRAIN system, the regular sheet drain performs its normal function of water collection, while the TOTAL-DRAIN section provides both water collection and a high-profile section for water flow to the designed drainage exits. TOTAL-DRAIN is a two-part, prefabricated geocomposite drain consisting of a formed 24″ high HIPS core covered on one side with a non-woven, needle-punched polypropylene filter fabric. The top section is 12″ of 7/16″ core for water ..read more

By Isaac Sorensen, CSI, Russ Snow, CSP, CTR, BSS, LEED AP, Scott Wolff, CSI, CDT, BEC, Conleigh Bauer, CSI, Stacey Bogdanow, CTR, Taylor Wodzinski, Patrick Raney, CSI, ICRI, and Roger Smith, CSI, ICRI After centuries of use, fluid-applied waterproofing continues to evolve as the primary method of structural waterproofing. According to Grand View Research, fluid-applied waterproofing is predicted to be a $37-38 billion market by 2025. Historically, humans have used variations of liquid membranes to waterproof their structures since hunters and gatherers used large leaves and tree sap to protec ..read more

LIQUI-HARD concrete densifier and chemical hardener compound is a proprietary, water-based, low VOC, ready-to-use, clear silicate liquid, formulated with chemically reactive raw materials to harden and dustproof concrete. This waterborne solution, when properly applied, offers substantial improvement in abrasion and chemical resistance and will significantly improve the durability of the concrete surface when compared to untreated concrete. As LIQUI-HARD is applied and penetrates into the concrete surface, a chemical reaction takes place, producing a byproduct that fills in the pores of the co ..read more

One of the largest problems facing structures today is water infiltration. When water and water vapor are able to seep into structures, it can contribute to mold growth and the durability of the structure.  As below-grade waterproofing is critical to the long-term performance of a structure, it is essential this is addressed with a complete waterproofing system designed and constructed specific for the structure.  According to The Concrete Network, “draining any water away and ensuring a dry interior space below grade can be relatively simple or fairly involved depending on geographic locatio ..read more
