Delta AT 800 Membrane 2m x 20m

Delta AT 800 Gas Resistant Cavity Drain Membrane

Delta AT 800 provides both Type C waterproofing and gas protection. It serves as a barrier for ground gases, including CO2, Methane and Radon. This Delta gas membrane also protects against water seepage, vapour and salts transmission, so your substrate stays dry and damp-free. 

This membrane is manufactured with Virgin Polymer, meaning that it’s highly durable and resistant to chemical erosion. The Delta AT 800 membrane aligns with both BS 8102:2009 and BS 8485:2015+A1:2019, so rest assured you’ll have complete and long-lasting waterproof and gas protection. 

Available in a 2m x 20m x 9mm roll.

Delta AT 800 Applications

The Delta AT 800 is suitable for all types of construction and can be used in new, old and retrofitting systems. 

Its simple installation process is fast and requires no specialist skills and is not destructive. As a reversible system that is easy to remove, it is ideal for old, historical buildings.

Delta AT 800 Membrane Installation

Make sure that the wall is clean and dry before applying the AT 800 membrane. It’s essential that gas membranes are installed correctly to ensure no harmful gases enter the building. 

Fix the membrane to the wall using Delta PT Ultra Plugs or, if installing on a softer, chalkier substrate, Delta FlexiDri Plus Plugs. Both plugs should be sealed with Delta Rope.

When sealing the gap between the membrane sheets, you can use Delta Tape between the joint and then Delta Corner Strip over the joint to ensure that there are no spaces between the sheets and water/ gas cannot seep through.
