I just had a well driller, drill my wells and install the grout for my geothermal system. Everything I read says that you should grout from the bottom up. However this guy grouted from the top. He placed his grout line down as far as it would go and then filled the grout the whole with grouted until the whole was full. My question is, should I be concerned that my wells are not grouted correctly? Thanks in advance for your help.
