Calcium floors

9 years ago

Hi

We began a kitchen extension in June last year and in September the builder contracted Ridgeons to lay 56 square m of calcium cement over our underfloor heating. We did as told and turned heating on 14 days after laying, kept everything ventilated and waited to lay the wood parquet floor. Now, in the second week of May we have cancelled the floor laying 3 times and have dehumidifiers working for two months, opened doors whenever possible and kept heating constant and low but still not dry! We are in contact with Ridgeons, who laid it, CoDunkell who manufacture it and Cemex who provide the calcium and have had hygrometers all over the floor to check moisture levels. Cemex' technical expert has now told us we have compromised it by living in it and having a sink etc providing moisture and that we should not have more than 50mm of it laid in this space, (we have 60mm at shallowest and 70mm at deepest). Moisture we have been told should not be above 70% to lay the floor and we have readings in last 48 hours of 93%! No one is accepting responsibility and no one ever told us we should not live here or that we were having this floor or the consequences of it taking so long to dry! We need advice on where to go from here. I have children revising for GCSE and A Levels and it is now getting beyond a joke, we need our home complete and of course now we have to pay extra for everyone to come back and finish even when it eventually dries. Please let me know if anyone else has experience of this product. Thank you
