Pila Sealing
I have a concrete block pila. It leaks and has been leaking. Stucco was applied to seal it but it still leaks. I was told yesterday to apply a coat
or two of fiberglass two-part resin (without the fiberglass) after completely drying the pila. If I survive the confined space application... I will
use a roller to apply on the inside of the tank
I'm looking for advice. Do you think it will work? Any other ideas?
Thanks
Marty

I don't have a good fix for concrete block pilas, most of the time people finally give up and buy the plastic "rotoplas" pilas and be done with it.

stucco is not water proof. that's why they use the paper underneath it-the paper provides the waterproofing.
this stuff is pretty good:

pila sealing
When I built under the floor pila tanks years ago out of block on the east cape I found a two part epoxy system in 5 gallon buckets that was designed
especially for storing drinking water[ my roof collected rain water and drained into the under the floor tanks and held about 18000 gallons when full.
I think there was a NSF designation for safely storing water to be used for drinking water which is why I chose this particular product. Over 15 years
later and no leaks. Great stuff, a bit of a byatch to paint it all over the floor and side walls but I don't know of another that is recommended for
storing water that is to be used for showering and drinking. I would still run it through a filter before drinking in case mice or whatever find their
way in there for a swim. I think I got it at Home Depot. Best wishes.

pila sealing
I forgot to mention this epoxy came in 5 gallon part A and Part B containers. It isn't cheap maybe $400 or so but you pay for what you get if you want
the best quality water storage without all the leaching that can occur with other sealing products.

tinaco
Why would you screw around with a concrete tank that will "settle", crack, and leak? You can get a grande tinaco for about a hunnert bucks. When in
Rome.........

Our underground cisterna is made of :
-Block covered with a stucco coat
- Then a layer of Merlex Superblockade - (applies easily with a masonry brush and we also use it on all flat concrete roof surfaces and below grade surfaces of
block walls).
- Then Crystal Lok which was rolled on with a paint roller. (excellent concrete waterproofer used for resevoirs, water tanks, etc).
No problems with our cisterna for the past 7 yrs.
Crystal Lok can be ordered and shipped from the manufacturer - comes in 5 gallon buckets and it goes a long way. If you're in Loreto now, you might
try contacting ACV Logisticas and inquire about shipping the product(s) to their warehouse in San Diego and arrange for it to come down on one of
their trucks which deliver to BCS.

I used a Mexican product called PegaCemento for leak proofing the beberos for m Mules in San Nicolas and Lopez.
Great, cheap, available and easy to appy. Dry 24 hours and presto - fill it!
Just ask at any hardware/cement selling hardware store.

ive had a couple of rotoplasts split...they aren't as strong as advertised
i would seal your pila it with pool plaster
think of a pila as a BIG pool
and pools dont leak
it goes on just like plaster and seals
whatever you do DONT paint it with a sealing product...that chalks in time
...but remember...
i tell people here this and no one listens

Check with Ken Bondy for anything related to concerete. He is an expert in that field. U2U Ken Bondy for answers.
The SAME boiling water that softens the potato hardens the egg. It's about what you are made of NOT the circumstance.

Try ThoroSeal. It is a cement type plaster. On fresh block I apply 3 coats. You can use a fiber bristle dutch brush. It comes in white and gray.
Dampen the block and first apply a white on the natural block and void are easily seen, follow with gray coat and finish with white. Mix with vinyl
bonder.

When you use the term "stucco" are you referring to the prepackaged stuff they use on houses? Maybe you mean "plaster" which is sand and cement.
Stucco has all kinds of stuff in it including paint and is not meant for submerged applications....just clarifying.

Bob and Susan wrote "ive had a couple of rotoplasts split...they aren't as strong as advertised" Pardon my French but that is utter BS. There must
be 10,000 tinaco's here in downtown La Paz and I have never heard of or seen one "split". I did have to replace the gasket at the bottom of one of my
tinaco's after 20 years. These things are hells stout. We also have a large cistern in the ground that was direct buried mixing a little cemento
gris with the dirt when we backfilled. The whole cost was less than 350 bucks including labor. Using products mentioned that have to be imported is
going to pee away way more than $350.

really...i guess ishould have sent you down the hole to cut up the 700 gallon "SPLIT" roroplasts
i couldnt believe it either since i put them in the ground in a cement container to avoid this
one time during construction the water guy was fill one and it just "exploded"
no reason...it just did it
they break...
whatever you do dont use them to haul water to and from town

I know tanks - underground storage tanks that is - I'd go double walled, fiberglass. But that's gasoline.....I know nothing for water tanks. Good
luck. Lots of good recommendations above.

Looks like Aqua Seal. Goes on columbia blue and is royal blue when it dries. 3 alternating courses usually does the trick.
