When installed correctly, elastomeric coatings help in ensuring which of the following?

Elastomeric coatings are specifically designed to provide flexibility, allowing them to accommodate movement within joints without cracking or compromising the seal. When installed correctly, these coatings create a protective layer that helps to extend the durability and service life of joints. They are effective in resisting environmental elements such as moisture, which can cause deterioration over time. By maintaining the integrity of the joint and resisting wear, elastomeric coatings contribute significantly to the longevity and performance of the structure, reducing maintenance costs and preventing damage from leaks or structural failures. This is why the correct answer highlights their role in extended durability and service life.
