Will Limelite with Permagard solve our damp issue?

Hi all. We're stuck between the decision to tank an external wall (thoroseal) or try and fix with a permagard solution. We're getting conflicting advice and going around in circles. Bit of background - the wall is currently gypsum with no damp proofing (or maybe a tanking layer that has long since failed). The outside of the wall is sand and cement rendered and goes beneath ground level at the window ledge height. It has had obvious signs of penetrating damp such as blown plaster and staining. We know that the gypsum has basically soaked up the water and caused more problems so we're looking at using Limelite as a more breathable solution. However because the wall goes below ground level we can't add channels so we're worried that using Permagard without a channel will just lead back to damp. Can you use Permagard without a channel with Limelite? Or would we be better off sealing the brick up to 1.10m with thorseal and then using Limelite so the inside can breathe? The house is 18th century so we want to restore sensibly but on this occasion, to stop the penetrating damp below ground level, what would work best? Many thanks in advance for the advice. M

Move watering can and don't plant geraniums against outside wall! Everyone knows geraniums don't like too much water! Try using a peat enriched soil and plenty of sunlight, hope this helps x

I used a product I bought from permaguard called Remners mb2 to tank below ground on my house.
