Hi Russell, thanks for the advice. Is this similar to a French gulley? Also, from what you’ve said, do you think the rain draining down the gap so far wouldn’t have caused any damage to the bricks or foundations? Thanks again.

Hi everyone, I’d appreciate some advice about a gap between my concrete path and the brick wall of my 55-year-old bungalow. The path slopes towards the wall, so rainwater flows into the gap and has likely eroded the pointing over time. I’ve checked thoroughly—no cracks, no internal damp, and no history of subsidence or settlement. Can this gap be sealed safely without causing trapped moisture, and what products or methods would you recommend? Could this water ingress have caused hidden damage below ground, and is there any way to check? Finally, would sealing alone be enough, or is re-grading the slope or installing a drain strip essential to prevent future problems? Photos attached. Thanks in advance for any help.
