How cap off soil pipe ?

[wickers]

Hello All,

The downstairs toilet to my 1920's semi has been removed.The non-load bearing wall has been removed that seperated it from the kitchen. I now have a larger kitchen with a clay soil pipe poking through the floor. When the toilet was removed the soil pipe broke away slightly below floor level (so no cap can be placed on it).

The kitchen floor is a solid concrete slab overlayed with quarry tiles. I therefore would like to concrete over the pipe and top with quarry tiles.

My two questions are;

1. What is the actual process of blocking off the pipe ? Do you stuff a load of paper down and top with about 4" of concrete to finish at the top of the pipe and then tile over that?

2. Should building control be involved?

Thanks for your help.

that should be fine although i would probably use a plastic bag first then the paper, maybe a bit of hardcore then the concrete. don't know if building control will need to be informed, give them a ring and ask.

Hello Steveb,

Thanks for the reply. Does the plastic bag, paper, hardcore and concrete get placed in the pipe one by one or does the paper and/or hardcore go into the plastic bag and the whole lot shoved into the pipe before pouring some concrete on top? Sorry if it's a daft question ? :smiley2:

not daft at all lol. plastic bag goes in first, really just in case concrete is too wet for paper alone. then screw up paper, then hardcore (to cut down on cost of concrete) then concrete.

actually if you can get to the outlet in the manhole it should be cemented that end as well rats love a unused pipe to nest in

Hello Steve ,

The pipe runs diagonally under the house before going into a manhole approx 8 ft deep (Severn Trent Water were digging around recently trying to locate a blockage in the area and come across the manhole under the hedge in our front garden !!!!!)....so this won't be an option.

Cheers for the reply.
