Is EPDM membrane 100% waterproof- Here's the truth

 

When you are looking for membranes for pond lining or roofing, you demand materials that have extraordinary water resistance. Among all the membranes like TPO, bituminous, and others, you should choose an EPDM membrane. 

Well, an EPDM membrane sheet is not 100% waterproof, but it is the most effective barrier for waterproofing.

Unveiling the Truth About the Waterproofing Properties of EPDM Membrane

• EPDM membrane is extremely non-porous in nature. As a result, it has a high water retention capacity. 
• The surface of the EPDM membrane sheeting is smooth and even. As a result, it prevents the accumulation of water and absorption. 
• Its molecular structure has dense cross-linking of monomers. Thus, water has negligible chances of penetrating through it. It is impermeable and does not allow water penetration. 
• An EPDM waterproofing membrane is puncture-resistant. Hence, it does not allow water leakage easily, even in the presence of sharp objects. It works as an effective seal and prevents water from seeping in. 

So, when can an EPDM membrane sheet become an ineffective barrier to water? 

According to EPDM membrane sheet manufacturers, these membranes have some limitations. An EPDM membrane sheet is known for its exceptional durability and resistance to environmental conditions. 

However, they may be damaged by excessive heat, UV rays, and ozone exposure. EPDM membrane suppliers say that subjecting your sheets to extremely sharp objects can cause wear and cuts. In such conditions, your EPDM membranes may be an ineffective waterproofing material. 

Thus, 

The waterproofing property of an EPDM membrane sheeting depends on its quality. It is a go-to choice for people for roofing, pond lining, and other waterproofing seals. The EPDM membrane sheet price of the cheap membrane is lower. 

However, they may break down due to the excessive exposure to external mechanical stress and environmental factors. This can affect their waterproofing properties.
