    Cant normally repair these types of faults. The end of the mat are usually sealed by the manufacturer to keep out damp etc. This is a heating element and I dont know of any kit that would join the ends.
    Fluke has a test kit but thats over £300.
    Looks like a total replacement M8

    the heating element should have had regular resistance checks as the tiles where being laid,to check it had not been damaged,when removing the tiles you will damage the element in loads of places if the adhesive has set.
    worth double checking that it is a break in the element and not just loose junction box connection.or have you tried this?. have you done a resistance check on the aliment tails?

    I had a similar problem with a conservatory which had an electric heating element laid, then 2 inches of screed. The element was damaged during screeding so no current flowed. Luckily it was clearly their fault so an electrician was brought in who could trace exactly where the break was. All they had to dig up was a 6 inch square of screed, rejoin the element and re-fill the whole. So the good news it should be possible. But you will need a suitable tone generator and detector to find the break and then whatever is necessary to fix the heating element. Maplin do a cable tracer/tone generator, code N74CC. But I cannot guarantee it would be suitable.
