In our last installment, Waterproofing Coatings Terminology 101, we reviewed some central concepts and terms in waterproofing to define the processes and materials common to our industry.  In this installment, we take a deeper dive into coating terminology with a focus on the concepts documented in important product information sheets--specifically Technical Data Sheets (TDS).

TDS' are essential for every applicator as they outline, in great detail, significant product and material attributes that are essential to firmly grasp prior to coating. Let's look at what it takes to fully read these important documents.

Drinking water infrastructure provides clean, potable water to countless people around the globe. In the United States (including territories) alone, there are over 145,000 active public water systems and nearly 2.2 million miles of underground pipes delivering safe, reliable water to millions of people. Continued maintenance and upgrades to this infrastructure are critical to the communities and asset owners they serve. 

Industrial waterproofing projects require a specialized coating system to meet specific coating specifications. The size and scope of work will influence the application method of these coatings. 

For this discussion, we will review factors to consider when spray-applying waterproof coatings on large-scale projects and the types of spray equipment needed to apply waterproofing materials. Projects with an abundance of vertical walls, overhead surfaces, and minimal risk for overspray are generally excellent candidates for utilizing spray equipment.  

Typically, the spray equipment used for waterproofing products can be classified as airless, air-assisted airless, or plural component spray equipment. Always use equipment recommended by the waterproofing material manufacturer.

The definition of waterproofing is very straightforward: to protect an object from water-based damage. Often, the main function of waterproofing material is to keep water out from an area or to keep water contained within an area. Regarding the residential, commercial, and industrial construction industries; there are many common terms to define the concepts and materials involved with waterproofing. Words and phrases related to product selection, site preparation, physical specifications, application conditions, installation, and testing, are just a few categories of terms that you may come across.

It’s said that two heads are better than one. The same principle applies to waterproofing membranes. Typically, you apply a layer of CIM waterproofing, wait for one to four hours, then apply your second layer. This is all after choosing a waterproofing membrane, of course. This is the recoat window for most membranes, and it marks the period of maximum adhesion between layers. That said, there are innumerable reasons why you may miss this recoat period.

It happens, and it isn’t an issue for experienced applicators. With the right tools and technique, you can abrade (rough up) the surface of the membrane to improve its ability to bind well after the surface has set.

Cold temperatures can impact the curing of coatings.  Applications at colder temperatures, or below the manufacturer’s recommendations, require experienced contractors familiar with CIM waterproofing products.  To achieve the best results, it is important to pay attention to the manufacturer’s application procedures. 

Let's begin by pondering this question: Why is waterproofing given less priority (left out entirely) during the pre-construction planning phase of any commercial or residential projects?  This trend is truly baffling as proper waterproofing care leads to innumerable benefits in the long-term life and performance of any construction project.

The global waterproofing membrane market is on the rise. With a focus on infrastructure and housing options, growth prospects in the construction sector continue to rise. Markets (including the United States, China, Brazil, and India) are seeing above-average growth in new building opportunities and restoration projects, resulting in an increased demand for elastomeric and waterproofing membranes and other coating products.    

With rapid growth worldwide, CIM Industries and its selection of waterproofing solutions, namely CIM 500, has started to corner the market with its revolutionary technology. CIM 500 is a two-part cold liquid waterproofing membrane designed to meet the demands of buried or non-UV exposed applications.  

There is a large misconception in the waterproofing industry that all cold fluid-applied waterproofing membranes are susceptible to osmotic blistering. But this is not the case. Over the years, costly waterproofing repairs have led to a lack of confidence in using cold fluid-applied waterproofing membranes in damp, wet, and immersion environments. Understanding what osmotic blistering is, knowing why it occurs, and choosing the correct product for each job will help minimize the potential for osmotic blisters.

Chevron raised the standards on cold fluid-applied waterproofing membrane applications when they introduced a urethane coating system for synthetic running tracks in the 1960s. Over several decades, this urethane technology morphed into a waterproof bridge deck membrane, now widely recognized as Chase Industrial Membranes (C.I.M. Industries), the leader in the industrial waterproofing market.
