RE: Concrete additives for Pool on roof?

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Yes it was successful in that the reservoir did not leak as evidenced by the underdrain system not discharging any water.  But we'll never know if it was the Xypex, the strict limits we placed on concrete shrinkage, the tight control we maintained on quality concrete and placement, the patching of any cracks that did occur, etc.

And ... and ....  ?   Don't keep us in suspense. 

Did it work?  Was it successful?  How long has it been in service?   Etc.

Hello,

I know that this is a bit non-typical, but I'm wanting to
find an additive that can be put in the concrete mix
that will make the concrete less pervious to water.

Does anyone know of a good additive that will keep the
water from moving through the concrete.  We're using
a high strength mix and water stops at the cold joint between
the floor/roof and the walls.  We are looking at using a liner or
a surficial spray on the inside of the pool, or an admix.

I was hoping that with a high strength mix, water stops, and
a good admixture, that we wouldn't have a high maintenance
situation.

Any tips?

Thanks,
Lloyd
