Well,
Started doing a large patio at the back of our extension a couple of weeks ago, of which i planned to carry out much of the initial ground work with a view to getting someone in to supply and lay the flags (indian sandstone) Unfortunately came accross this site around 2 weeks too late in the process and am in a bit of a pickle and looking for some ideas. Overall area is approx 70sq m (35sq m of which is a large oblong area 10m x 3.3m) which needed a low wall approx 250mm from ground level along the edge of the lawn to bring it up to level with the rest of the patio area.
This area was previously lawn so i removed turf and filled with 40mm crusher run built up progressivly in 4" layers with numerous passes of a 85kg wacker plate so i now have nice level firm area (with fall away from house) So far so good....unfortunately the wall i built which was on 250 x 125 strip foundations & single skin of bricks has rotated 5mm out of vertical. Whether this was due to me driving a 600kg skidsteer backwards and forwards to dump the 10 tonnes of hardcore, & the wacker plate, and that it is likley to now behave itself i don't know, but i am not inclined to leave it like this. Whatever I do i need to get someone in to sort out as work is too busy, but wondered if anyone had an opinion of what I should ask them to quote for
I am assuming 4 options, with 1 or 2 being my preferred
1. new footings and single skin wall in front of existing wall (making the patio a bit bigger, knock off the top course of bricks and tie the 2 together filling the void with concrete
2. as above but new double skin wall and leave my wall as an archelogical curiosity burried under the now deeper patio
3. underpin the strip foundations (assuming that is the problem) seems a bit OTT for no guarantee it won't fail
subsequently
3. dig out the whole thing including the strip foundations and start again saves on flagstones, but i presume will cost the most in labour / disposal
unless anyone knows someone who works out of harrogate area who could do me a rescue job to save my marriage!!
will try and post some photos to illustrate tonight
