DPM & Retaining Wall - How to seal the bottom

thebeetleuk · 1 Sep 2015

Hi All,

Building a 1m high retaining wall and I'm having a few issues. I'm tanking the back of the wall with a bitumen sealer and for additional waterproofing I'm putting a DPM (e.g. http://www.diy.com/departments/ndc-blue-damp-proof-membrane-1000/35630_BQ.prd) behind that. My issue is how to seal the bottom of the DPM to the wall. Any ideas?

Thanks in advance

If i understand: you have used liquid bitumen to seal the back of the retaining wall (a garden retaining wall?) and now you want to "tank" over it with some membrane. Why?
Why not simply leave the bitumen as a stand alone sealant?
