14-06-2017 02:20PM#1hi
we got a new bathroom extension.
where the builders broke into the old manhole wall to lay the new soil pipes they left gaps that need filling.
i have cement, sands, pva in the house, but do i need a admixture/additive for the mix
maybe integral waterproofer or sbr ?0

If the patch isn't going to be exposed to water (as in funnelling away the waste) hen I don't see why simple sand cement won't do it. A splash here and there won't hurt it.0 -

ty for the answers,
guess i was paranoid about it all failing and blocking up drains while the cover is on hiding it.
@thepenturner i was gonna pva the gaps and pipe first as a bonding agent/key0 -

pva is rubbish, its only good for cildrens play time
it is water soluble so if the water gets to it the bond will dissolve.0 -
