Footpath wanted but Yard higher than dpc

corkboss

I want to put a concrete footpath around my house which is a renovated cottage however there is slope in the yard which rises about 12inches(after 30ft) from floor level. If I put a DPC under the footpath will this suffice? Any comments would be appreciated,
Thanks

Not sure if you mean that the path will also be above DPC if so....

To do it properly, you would really need the "tank" the wall that is above DPC & below the path, or build a small retaining wall to separate the path from the house wall.

else..

Provide drainage along the edge of the yard before it reaches the path.

you need a material which is a tough polythene layer with bitumen

( Sorry mods - hope this is ok ) - trade names are Bituthene , Bikuplan - there may be others


you should cut back to footings ( if any ) allow the wall to dry out ( best you can in this so called summer weather ) . The bitumen prime the walls and top of footings and apply the product - which is a bit like a huge bicycle tube repair patch . Take it up as up far as the footpath .

Sorry but With the old cottages the only real option is to lower the ground level outside, tanking the walls outside wont stop the water rising through the floor inside.
Best practice is to dig out around the house until you are below the inside floor level, put in land drainage pipes wrapped in geotextile membrane(and if necessary connect to a sump and pump) fill with larger diameter stone and either finish with stone or cast your footpath. Dont rise any higher than the floor inside.

thanks for the replies. Inside the house was completely renovated, new floors, drylined etc so I presume there was some sort of DPC under them. Lowering the yard isnt realy an option, it rises up to the road (gable 5 ft from the roadside). Would drainage as described above between the path and the wall of the house do or is it better to have it outside the path? Im conscious that the old part of the house just has stone as fondations

Maybe i'm missing something. But the path isn't above DPC adjacent to the house.
It is above it after 30 feet.
Assuming that it is 150mm or greater at the wall, then there is no need to additional work. (i must be missing something)

sorry, i should have described it better. The slope starts at the door, rising gradualy to about 12 inches after 30ft along the side of the house, so most of the yard at that side of the house is higher than the floor level inside

Dryling the wall and renovating are just dressing the structure. A DPC stops water from rising up through the wall by capillary action. Walls arent inherintly waterproof unless designed to be. Water will eventually find a way in and drylining just hides the problem

Oh ok, so it rund along the house, for some reason I was thinking that it runs away from it.
