Sorry BankFodder,
I will try and explain further.
We brought the house in 2016 and decided like many to extend the house and sort out the garden, the extension and garden was done by the same company and was started 01-Jun-22 and finished mid Aug-22.
We have had some internal issues within the new extension and existing building, but the more concerning, costly, and worrying are the issues within the garden.
We started to notice there are a lot of porcelain tiles where the grout lines between them are cracked and no longer joined to the tiles.
The tiles have started to move, so they are no longer fixed to the underlying material, to now where they are rocking when you walk over them.
There is a small brick retaining wall only 3 courses high and this has cracked where the movement in the ground has occurred.
But because the original builder is not returning any of our call or responding to our messages or emails.
We have contacted a couple of other builders/landscapers to come and establish how much it would cost to rectify the problems I have listed above.
When they reviewed the issues, we have they have pointed out further issues we were not aware of.
The retaining wall made from the Concrete posts and gravel boards is moving, and so far since Aug-22 to now it is 20mm out of plumb.
This has made the tiles within 2 metres of the above wall drop by 20 mm, cause the issues I have listed above.
They have also pointed out the floor level outside should be 150mm minimum below the DPC course of the new extension, at the maximum it is 140mm below DPC which I would say covers 20% over the external wall, the remaining 80% is somewhere between 120mm down to 90mm.
Neither one would be willing to work on the garden in its current state, as it will continue to move, and it would do the same to their work and so they would be unable to guarantee their work.
To rectify the DPC issue, we require them to remove all the existing tiles and change the levels of the ground and reapply all the tiles, that’s if they don’t break them getting them up.
Hope this explains the situation further, we need to get this sorted, but surely this shouldn't be at our cost again, we paid for a job that wasn’t done correctly and does not meet the Building Regulations and I would say this is falls within Poor Workmanship.
Best Regards
Ian and Deb
