Waterproofing, how difficult can it be? You purchase the product, get either the sprayer, squeegee or brush ready for application, then spread the material and let it cure, right? Not quite. Waterproofing certain areas is a crucial component of many architectural and industrial projects. While the process may seem simple, there are several factors requiring close attention to ensure the best outcome for the project. Most important among those are product selection and application.
The importance of a well-built building structure is often taken for granted until failures start to appear. These deficiencies can be minor or major, but the results are often catastrophic. This is why consultants play an important role in the waterproofing industry and may add in saving you money in the long run. They add an extra quality assurance check before construction or after a roof or deck fails.
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.
