damp proof method

[svouts]

i got reports from two companies on damp proofing. one claims to drill 12 mm holes in the wall and then apply damp proof cream inside. the other claims to drill 10 mm holes in the wall and apply damp proof liquid with high pressure pump.
is any method better than the other one?
Thanks in advance!

PS:the second is twice more expensive...

I don't have a lot of faith in either.

Sounds like exactly the same thing? The "under pressure" method will better saturate the bricks I would have thought.

There's a kit available from HSS if you want to have a stab at it yourself. I'm sure there's a video of someone on youtube spraying liquid dpc all over themselves...
