Leak Repair - Part II
The repair dudes are back. Today they're injecting a purple-ish epoxy substance into the wall cracks. They inject it with a small electric pump with a pressure gauge on it. They watch the pressure closely as they inject small pulses of the material into the cracks.
The process is not too noisy or messy. The epoxy has a rather strong odor, but as long as my windows are open, it's not a problem.
