On the subject of screed drying....... Up to 105 days is bonkers & less than helpful. What is a relaible way of testing when the floor is in fact dry enough to tile. I have heard of a humidity test. what exactly is involved in this please?

That was my understanding as well, how wrong was i? At the least i would expect that the screed company would do this. I paid for a one stop shop approach and said so clearly on every ocassion i had any communication with the people i contracted to do this. It is done now but has cost me £500 that i would rather not spend on this. I did it myself, the cost was hiring the kit. Now just have to wait until the floor is dry enough to tile.

Nick no i dont expect anyone else to endure my efforts to remove the Laitence. I intend to use my trusty Henry hoover attached to the grinder, and if i have to change the bags often then its a reasonable compromise against another £240 for an extractor. More than the grinder itself as it happens.

Does anyone that has experience know if the dust extraction is essential. If i need it i will hire also but it more than doubles the price

If i could find one to hire close to hertfordshire i would do so.

In case my scraper does not do the trick tomorrow would you indicate exactly what floor grinder you used please

No scraper yet but i will pick one up tomorrow. To be honest the rotary thing has a mind of its own anyway.

Yes Anhydrite of some variant. I basically scrubbed until the amount of dust being given of reduced to almost zero. I hope thats good enough.

I need to scrub the 'scum' off of our new wet screed. Initially this generates a lot of dust so is clearly removing material. I have no idea how far to go with this process. I am using an industrial rotary floor scrubber like you used to see at schools etc. Anyone know the process for this task? Thanks in advance as always. Keith

No credit due to me. Frame is from Potton Homes and liquid screed from 'flow2go' i think. After all my frustrations with some of the stunts Potton pulled its nice, #1 to be able to say something positive about them and #2 for the choices to bear fruit.

I had the kitchen company do their final measure prior to manufacture today. The guy remarked that co incidentally 2 measurements from freshly screeded floor to ceiling were millimetre exact at 2366. ' i'll never get that again' says he. So he did another one from a remote point from the first two. 2366mm ! He then said that every wall corner to corner dimension and corner angle was bang on. Sometimes things do go right.

Soil samples were taken prior to groundworks from 3 sites on the plot. Based on whatever was discovered a percolation test was not required.

I get it, i just dont understand the logic. Becuase its a very expensive thing. As regards attenuating against a large sink hole. The water from a soakaway will leach away at some rate. The same volume of water from 4 x gutter pipes laid underground and sloping away would leach away at the same rate over a large area. But crucially be easier(cheaper) for me to install.

The plot is 3/4 acre and sloping away from the house. Which is why i question the need for any soakaway. I cant see why i cant just run perforated pipes down the slopes.

JohnMo: No not sure, i trusted what i was told by BC & others. Its worth learning how to use a digger i think.
