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.

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.

Cold, fluid-applied waterproofing membranes are popular choices in the construction and building industries because of their versatility in areas where traditional sheet waterproofing or hot-applied membranes are not options. Cold, fluid-applied waterproofing membranes can be applied to both vertical and horizontal surfaces and, when installed correctly, should last for many years. Understanding and following the installation guidelines will help ensure the application's success. Cold, fluid-applied waterproofing membranes’ robust physical properties and long-lasting performance are why manufacturers publish application and installation guidelines that must be followed.

A waterproofing warranty is a legally binding agreement which a company guarantees that some or all its work will be free of defects, typically for a specific length of time, and is normally approved and signed by both the owner of the project as well as a representative of the company manufacturing the product. A warranty provides for a remedy in case there are certain problems with the product provided to the customer.  The intent is to provide peace-of- mind to the customer, ensure the product is backed by the company and is consistent with claims related to performance and reliability of the product. If you purchase a waterproofing solution and later discover that it’s defective, you can file a claim with the company – assuming the waterproofing solution is still under warranty – to recoup some or all the cost related to the product.  A warranty is essentially a company’s assurance that its product will live up to its claims.
