Which material thickness is acceptable for damp proofing?

When it comes to damp proofing materials, the acceptable thickness is crucial for ensuring effective moisture control in building structures. A thickness of 60 mil for flexible polymer damp proofing aligns with industry standards that stipulate minimum performance requirements for protecting structures from moisture intrusion. The 60 mil thickness provides a robust barrier, helping to minimize the risk of water vapor transmission and therefore safeguarding the integrity of the building materials and the overall structure.

In contrast, other thickness options may not provide sufficient protection. While 30 mil may be used in certain applications, it does not meet the recommended thickness for damp proofing to be considered reliable in most conditions. Choosing any thickness without specifications may lead to inadequate moisture protection, while the option of 15 mil or thicker is too vague and doesn't adhere to the more precise standards required for effective damp proofing. Thus, selecting the 60 mil flexible polymer ensures compliance with the regulations and longevity of the damp proofing system.
