I have some rather large holes between my garage and main house where previous owners/contractors have installed pipes and electric cables (boiler and meters in the garage area)
- half a brick width with some cables to the upstairs underfloor
- a whole brick removed for CH/Water to upstairs underfloor
- halfish brick width x two brick high for CH/Water to the downstairs underfloor
I'd really like to seal these to some extent, not sure the best thing though - stuff rockwool or similar in, expanding foam?Appearance isn't really important as its only on the garage wall side, but it might help keep drafts and critters out.
