Screed laid too high

[travisbickle]

So we had our appointed plasterer/screeder screed our Polypipe underfloor heated floor in our new extension on Friday and despite asking time again about how he would check the levels and requesting that he leave a clearance of 35mm below the threshold of our bifold doors, he has messed up.

Though on one end of the doors, the clearance is approximately 35mm, it narrows to 28mm near the middle and back to 31mm at the other end. This is unsatisfactory because it does not leave sufficient space for our stone slab flooring. I am majorly ****ed off because I made it abundantly clear that they had to leave 35mm under the rim of the threshold.

My question is, can anything be done. He has suggested hiring a grinder (at his expense) to correct his mistake but won't that just end up damaging the ufh pipes?

dont pay until he comes up with a suitable solution.

So ........... where or at what level are the pipes in the screed then? Surely there's loads more screed than 6mm above the pipes?

Winds me up that. Happened on a job I've just laid Amtico on. The screed wasn't done right and too high. I had to do a lot of work with smoothing compounds to sort it out then slope the floor at the doors. Looks rubbish and now I have to put a trim on it.

Yes a grinder with a diamond disc like these

That will grind it down.

Could an industrial sander not suffice because at most its just 6mm?

Using a grinder worries me about potential disruption of the ufh system.

A grinder is the tool for the job, after all, you want to grind the level down right? People often use a grinder for cutting, with a cutting disc, so I suppose this leads to a little mis-conception?

The disk linked by dazlight would do the job.

The bigger the grinder and disk, the easier and more accurate the finish will be.

But yes, care will be required to not damage any pipework. Any damage would need repairing, and a small amount of screed / cement used to patch it up.
