What is a building envelope?
Environmental conditions can wreak havoc throughout all phases of a coating’s application, but what happens when the wrong tools are used during the mixing process or the material is mixed incorrectly? To avoid negative effects of improper mixing, the manufacturer typically provide technical datasheets, application guidelines, and technical support to aid in the completion of a successful application.
The most common method employed to tie into an existing hot rubberized asphalt system is to use more hot applied asphalt. This involves using hot kettles and can present some jobsite challenges, such as mobilization issues, safety concerns and foul odor. Cold-applied membranes can address all these concerns. Consult the manufacturer of the cold liquid-applied membrane to verify approval of application procedures. Manufacturers may be able to offer case histories, detail drawings, and application guidelines to help provide technical support needed for tie-in methodology.
Most methods, however, will include the steps listed below.
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.
Cold temperatures can impact the curing of coatings. Applications at colder temperatures, or below the manufacturer’s recommendations, require experienced contractors familiar with CIM products. To achieve the best results, it is important to pay attention to the manufacturer’s application procedures.
When installing tile, whether it’s flooring for a restaurant kitchen, a swimming pool or a patio deck, the process should include waterproofing the substrate prior to the tile installation.
The World Trade Center memorial (WTC) in New York City contains two enormous fountains which presented many waterproofing challenges.
The contractor team spent over 18 months installing the concrete waterproofing system that was selected for the job. Here are the methods utilized:
When designers started to plan what would become North America’s largest man-made waterfalls (World Trade Center Memorial -WTC) in New York City, they faced a number of challenges. One of the biggest concerns was how to contain vast quantities of water while preventing infiltration into underground structures.
Clean drinking water is often taken for granted. Drinking water standards are more stringent today to ensure that water is safe to drink. In 1988, NSF/ANSI 61 Drinking Water Systems Components – Health Effects standard was published. There are several laboratories certified by ANSI to test to this standard, including Underwriters Laboratories, the National Sanitation Foundation, and the Water Quality Association.
