Hi
I have a leak where the two part concrete cill on one of my windows joins in the middle. There is a small gap, less than one eighth of an inch. It has been siliconed but the rule of depth not exceeding width broken so the seal has failed. Water is going through the cill into the blockwork behind render and into my conservatory.
Any advice as to how to fill the cill join gap appreciated.
