We’re delighted to be launching Delta AT 800 an innovative Type C Drainage Membrane which satisfies both BS 8102:2009 and BS 8485:2015+A1:2019, Table 7 achieving waterproofing and ground gas protection simultaneously.

Delta AT 800 will lessen the complexities of waterproofing and gas protection to below ground structures where BS 8102:2009 and BS 8485:2015+A1:2019 do not currently align.

Delta AT 800 has high compressive strength, excellent compressive shear behaviour, high resistance to alkalis and satisfies ISO EN 15105-1 Methane permeability (manometric test method) requirement as stipulated in Table 7 BS8485:2015 +A1:2019.

The Delta AT 800 can be used as part of a twin waterproofing and gas protection system in conjunction with Delta’s MemTech gas protection systems and its waterproofing range.

Delta AT 800 is suitable for new, existing and retrofitting systems.
