How to waterproof external wall?

[tom138]

Hey everyone,

I am hoping to get some advise re waterproofing this external wall before I get a concrete path. 

As you can hopefully see from the picture above I have exposed the footer and was planning to use this waterproofer  but thought I’d check first whether is it the right product for this job. Or is there anything more suitable? 

Few other questions I have:

- how do I prepare the surface before applying the membrane? There is obviously still traces of dirt and stuff and I at first I wanted to use a pressure washer to clean it but not sure whether is it a good idea and whether am I going to loosen up some of the old mortar. Also if I pressure wash it now it might not get dry before the next rain and I wanted to take advantage of the few days with no rain on the forecast. Could I just get away with using a brush or wire brush to get rid of the dirt?

- do I need a primer/sealant?

- where do I apply the membrane? From the footer to the dampcourse?

Any advise is much appreciated!

Thanks,

Tom
