Dryzone Damp Proofing Cream 310ml - DPC Injection Kit: 24m Coverage (9" wall) - BBA Approved Rising Damp Treatment

Drilled every 6" then drilled above the next brick between the 6" so formed a triangle shape. Those that said the nozzle keeps coming of is simple to rectify by placing a piece of insolation tape on clear nozzle and the blue adapter that attaches to the tube, When injecting the cream don't go made by pressing the trigger otherwise the cream will spill out the sides of the hole whilst your tube is still in the hole, i gently pulled the trigger whilst gradually pulling the tube out, i did this around every inch or so, you can feel slight pressure as it fills and at that time is when i gradually pulled it out. Obviously only just completed the task and have to wait to see if it works, don't expect this to work over night, like any damp proofing solution you need to give it time. could weeks or months depending how wet your walls are. It is a little expensive but hey if it does the trick i be happy and worth the money. I drilled in around 8 to 8 and half inches on 9 inch brick wall.

Seems to be working.
