Workshop floor made from easy screed?

miss no stars

Just want to get an opinion on this. Might keep it a bit vague for certain reasons.
Say you have a building as described: HCB walls (no insulation), flat roof, concrete floor; strength and depth unknown. The ground level outside is above the floor level on some sides, but it's not possible to tank externally due to it backing on to neighbour's property. In heavy rain it floods.

The plan was to raise the roof, raise the floor level and tank.

External tanking was a no go so a DPM was to be returned up the walls to a certain height along with the normal DPC.

As for raising the floor - there was to be 100mm insulation plus 150mm concrete on top of the existing floor.

Due to a problem, this had to be altered to what looked like 60mm insulation and about (not sure of the exact figure) 75mm Easy Screed. Can't be sure, but it was a LOT smaller than originally intended.

Now, I know easy screed isn't a bearing surface but I'm fairly certain that, due to the builder not closing up the gaps for the windows and doors, it dried out a bit (chips and scratches all over it, actually). The builder then proceeded to drive over it in a digger *sigh*. I'm also concerned about the DPM that was put down as it was extremely flimsy - about as strong as a cheap bin liner. Also, when it was poured the DPM hadn't been tucked and folded properly so the sides of the DPM are under a lot of stress and the easy screed didn't quite make it to the join between the wall and original floor.

I'm curious about the floor. It was intended as a workshop so will be exposed to a reasonable degree of vibrations and heavy objects (possibly being dropped) on it. Water is a big issue as it's a woodworking workshop so needs to be dry inside. (lino tiles were put over the easy screed). How long could this floor be expected to last and remain waterproof?

Opinions?

I had a disastrous time with a screed company from the midlands and had cracks everywhere, these were not easyscreed although they all pretend to be, my story started with it cracking and coming up in lumps. I researched it for a few weeks and eventually called "easyscreed" and spoke to some guy who sent an engineer down to attached some pressure guage to the floor and test it. I have to say that he did all this for free and then after that I spoke to some guy called Jerry, I think he is the owner of the business. He talked me through all the things that had happened from the photos the enginner took. He said that there were many companies that try to clone his product and cant seem to get the formula correct. to cut it short I had "easyscreed" do it again and there has never been a problem ,I got charts , diagrams, photos and all proving that it was 70mm think and as durable as concrete as long as it wasnt wet everyday and outside, needless to say this was in my kitchen extension. to date heating is perfect nearly 10 months after "easyscreed" and 18 months after the orginal disastrous company
