Channel in concrete floor dpm

silencio · 4 Jun 2023

Having problems on a build. Builder cut a channel in the existing concrete floor to run electric cables through. It looks like he went overly deep and through the dpm? That being the case how do I resolve and what's the best way to fill the channel? Its about 150mm deep and 3.5m long. Couple of armoured cables running through to outbuilding and some ducted cables for kitchen.Eventually it will be levelled and tiled.
Thanks

Line the channel with some 'U' shaped poly, then fill with conc' or screed.
