I have a single skin, brick-built garage. One of the walls of the
garage acts as a 'retaining' wall for my next-door neighbour's garden
to a depth of @ 2 feet. Consequently, when it rains particularly
heavily, water penetrates the brickwork where it supports their garden
and fills my garage with a considerable amount of water. I was advised
to apply a bitumen based waterproofer on the inside of the wall. I
applied 4 coats of 'Aquaprufe' to hold back the water. It helped for a
while but after 9 months or so I'm back to square one and water is
seeping through the wall.
It is not an option to access the neghbour's side of the wall for
various reasons. I have been told that rendering the inside of the
garage with a sand/cement plinth over the bitumen exceeding the height
of the damp problem could solve this. Has anyone any ideas or
You are entitled to access to a neighbour's land for essential repairs and you
can get a court order if necessary to enforce this. The act is called - rather
conveniently - The Access to Neighbouring Land Act 1992. Google will elucidate
further. I would have thought your only long term solution is to stop the water
getting into the wall from outside rather than trying to prevent it seeping
through when it's already gained access.

I'm not at all sure why women like men. We're argumentative, childish,
unsociable and extremely unappealing naked. I'm quite grateful they do though.
What's the legal situation here? If the wall wasn't built as a retaining
wall (the neighbour has used it as a convenient way to create a raised
bed) is the neighbour not obliged to keep the ground level below the
I ask because two adjacent walls of a neighbours (detached) garage form
part of the boundary of my garden. I have ensured that the soil level is
below the garage DPC (although not necessarily the 150mm applied to a
house DPC) which meant me sloping the lawn more than I would have liked.
This year we will be making changes to layout of the garden since the
extension has swallowed up a good chunk of it. One of the plans we're
considering includes a garden shed next to this garage. Is there a legal
requirement for the shed to be a minimum distance from the garage, e.g.
sufficient to permit the owner to access the wall or is it just down to
common sense and being a good neighbour?
However, if the damp problem problem has been caused by your neighbour
not taking sufficient steps to prevent damage to your property I don't
see why it should be a problem to ask your neighbour to remove the bed
and ensure there is proper damp proofing before re-establishing, or, a
better solution is to remove it altogether.
I would say damage to your property caused by your neighbour could be
classed as illegal, or something similar.
I think it comes down, as you rightly say, to being a good neighbour
with common courtesy and respect for others property.

not really doing any good trapping the damp in the walls.

Yes...the houses were built like this! The estate is on a hill and
most of the garages are built this way. What makes it even more lousy
is that the 'retaining' wall of the garage has a bitumen DPC situated
about 20" under the soil level. I thought that retaining walls should
never have this type of DPC because they can 'slide' and become
unstable. Still, that doesn't help my current situation. I know that I
can gain access to the neighbours to carry out essential repairs etc
but aren't some damp treatments designed for application on the
'negative' side of the wall?
After all, how do old cellars get sealed off? Is it always necessary
to access the 'soil' or positive side of the wall?
If I do have to do that, then what treatment should I use?
I'm sure I read a leaflet giving guidance about party walls from the
It was mostly to do with building, your neighbour is not allowed to stop
your builders from getting access to the wall, and I'm sure this law can be
used when it comes to maintenance issues as well.
You really need to dig out this soil and place a damproof membrane against
the wall. It will also have to go into the mortar a couple of bricks above
the soil level.
