Dear friends

I would like to find out if anyone has knowledge/experience dealing with waterproofing works during rebuilding, beyond the standard additives applied to the relevant areas exposed to the elements.

For me, I am using a high quality additive for my roof already, that’s what my designer tells me. As for perimeter vertical walls, dual layers of bricks are used everywhere, water seepage risk is supposedly very low. 

Will you ask for additional waterproofing treatments and for which areas?

Kindly share your thoughts.

Thanks very much.

Additives even by manufecturer warranty lasts 10yrs. And thats by application in near lab conditions. The way to meet sg ppl expectations is in the design, not the treatments. Ie.. no flat roofs, water do not touch painted surfaces.

U will notice that new high value construction uses concrete external walls instead of bricks. Double layer brick is for heat insulation, not abt waterproofing.
