Browse Forums General Discussion 1 Nov 01, 2017 4:40 pm I live in a block of 6 townhouses. Electricity is supplied to each through 21mm cables and they come together from the back of the building through the ground floor slab with one dropping down out of the bottom of the slab to each unit as they pass through. A small amount of rain water (enough to do damage) is coming out of the cable hole in the 2nd last unit every few months. Flood testing and general logic says it is very unlikely to be coming 35 metres along the cable. The other possibility is from downpipes embedded in the walls but it would have to penetrate the slab (it is a single slab for the 6 units). My question is: is it most likely that the cables come through a conduit embedded in the slab at pour time or might they have left a channel in the slab which was filled after cable laying (thus opening up the possibility of cracks)? Thanks for the insights, that makes perfect sense, and yeah, I will be leaning on the experience of the excavator operator entirely. 6 16160 4 6201 The concreter will take and reuse. In my case I bought structural LVLs and scraped them back and used them as joists. 1 5164 |
