Confirmation of Gas Works

Good Morning All I have a very big issue here as I'm currently in the process of building a kitchen extension. During the course of this extension, I had arranged to move the Vaillant gas boiler from the children's room upstairs to this new kitchen. The copper pipes (which were sheathed) had been laid by the Gas Safe engineer prior to laying the screed. In addition, another set of branch pipes had been laid from the proposed new boiler area to an area designated for a radiator ( this was about 5.1m long). 3 days after this, the concrete screed was laid. 6 days after the screed had been laid, the plumber had been requested to complete to gas boiler relocation. The boiler was moved from the old location and all heat and gas connections appeared to be working OK. Now the screed ( which is about 65mm thick)is in the process of drying. It is clearly visible that all areas in the new kitchen appear dry except for the area where a copper pipe joint connection exists under the screed. I had suspected that there was a leakage around the pipe joints as the copper pipe length was more than 3m but I had felt that the screed had not dried yet. I had raised my concerns with the plumber who advised me to check the pressure on the boiler which was 1.2 bar. He advisef if this were 0, that this would have implied a problem. I had monitored this for a further 3 days and confirmed that a slight improvement in drying had occurred which could mean slight CH water pipe leakage in drops. Now this is giving me great source of concern as other forums have suggested this may be a leakage. This little issue appears to cause delays to other parts of the project. Could the reason for the delay in screed drying be attributed to a copper screed reaction, an ignorance on the part of the plumber ( by not welding the joints on the copper pipe properly) or that the screed had not dried completely. I can send you a picture if you require this as it looks like damp patches. I was thinking this was just a coincidence but the area which appears damp appears to be the area where the pipes were jointed within the screed. I have since contacted the plumber but they seem not to respond immediately. The flooring is supposed to be implemented this week by the builders but no response had been received. The radiator has not been connected at the new point but had been capped. At this stage, I need a professional advise from your team of experienced Gas Safe engineers. How do I confirm that there is a water pipe leakage within the screed. Are there water pipe detectors which plumbers can use to check this.
