Hi,
I'm a newbie, I've looked at the site and archive so appologies if this has been done before but I have tried...
I moved house in january and each time we have heavy downpours or prolonged days of rain my garage floods (approx 1-2" deep from rear towards the front)
My neighbour says this is an old problem tha the previous owners never really solved. (they built some sort of wall at the back of the garage to push back the soil level)
As far as I see it the problem is this, the garage is lower than the surrounding land. Behind the houses behind mine there is a large field that is approx 6ft higher than my garage, the houses behind me have sloping gardens towards mine. The bottom of my garden has a raised grass area approx 4ft above the level of the garage with a patio approx 1ft above garage floor level. The front of the garage has a drive sloping down towards it (no water comes in this way due to a 1" concrete lip, i've watched it).
The garage has good guttering which does empty to sw drain (I checked it with a bit of dye)
From looking at the site I have considered a land drain round the back and 2 sides of the garage with a linear drain at the front, all connected and connected to the sw drains.
To me the fin drain sounds ideal but you say it is not so readily available to the DIYer.
My headache is trying to work out how to marry them all up without having to replace my entire driveway.
I think the land drain bits need to be quite deep looking at your site, however they SW drain I want to go into is next to the driveway where the shallow linear drain would be. As water doesn't flow up hill very well I wondered how the best way of tackling this was.
The soil round here is quite sandy so the flooding soon receeds but by then the damage is done. I am also conscious Not to drain too much that the sandy soil is left too dry.
Any ideas/suggestions welcome
Thanks
David
