IMS were recommended to us following years of historical issues regarding drainage within the building. IMS attended site and were able to produce a comprehensive report on the drainage within the building. Through this report they were able to recommend a new drainage regime required for the building as the previous regime was insufficient for the occupancy of the building. This regime consisted of focusing on historical problematic areas. I was also delighted with their method of breaking pipe where required to remove build up as opposed to just pushing issues around the system by pressure jetting alone, this method has seen our drainage call outs reduce by 90% over a two year period. I cannot recommend IMS enough
