I found instructions for plugging thermalite somewhere once. Two important things - don't use a masonary bit and don't use hammer action - these both destroy the structure around the hole.
You need a parallel sided cutting bit, to drill a clean sided parallel hole. A cheap bit is usually fine, as these don't have a long life drilling into cement anyway.
A soft plug (e.g. plastic) may distribute forces more evenly, avoiding pressure concentrations which canbreak the block structure around the hole.
