The Evolution of Fluid-Applied Membranes – The Construction Specifier (09/20)
Print Version By Isaac Sorensen, CSI; Russ Snow, CSP, CTR, BSS, LEED AP; Scott Wolff, CSI, CDT, BEC; Conleigh Bauer, CSI, CDT; 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 protect their excess grain from moisture. In the…
LIQUI-HARD
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 concrete. This process produces a substantially denser concrete surface with enhanced durability. In addition to the densifying and…
Waterproofing
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 location, climate, topography, soil/water table conditions, and depth of…
