What is the primary purpose of end dams in construction?

End dams are specifically designed to prevent water ingress in construction applications. They act as barriers that redirect or block water from entering certain areas, such as at the edges of roofs, balconies, or other potential leak points. This is crucial in maintaining the integrity of the building and preventing water-related damage, which can lead to mold growth, structural issues, and deterioration of building materials over time.

By effectively stopping water from coming in, end dams play a vital role in waterproofing measures and contribute significantly to the overall durability and longevity of the structure. This function is particularly important in regions susceptible to heavy rainfall or where proper drainage may be limited.
