Pila/cement sealer????

bajadave1 - 4-25-2006 at 09:27 PM

What is everyone using to seal the walls of their block/cement pilas? I've been told about a two part epoxy, but would like to hear more input. This is for a potable system. Thanks.

We're using a product called Crystal Lok on a below-ground concrete cisterna:

Can you buy that stuff in Mexica?

Bajajudy-

They list a distributor in Ensenada, but the company makes other "Marine coatings" so I don't know if they carry this product specifically.

Here's the link to all the distributors:

Looks like they have more distributors now than when I bought the stuff last year. At that time we called San Diego Marine Hardware and they had a 5 gal cubeta shipped to our door (from Wash.).

Our tank is 4 ft deep, 30 ft long, and 8 ft wide and the top forms the sidewalk around the garage(couldn't go deeper due to lava rock below). The access hatch is a 2x2 ft opening we located inside the utility room in an attempt to keep the dirt to a minimum. I'm the smaller of the 2 of us and, unless I'm more claustrophobic than I realize, I'll be applying the Crystal Lok to the inside tank walls in 2 weeks and will let ya'll know how it goes.

better vent the stuff or....you'll die

Or borrow a diver's 'Hooka'...

...and use it to breath while you're in the 'pit'...with only one opening, it will be hard to vent properly...caution here!

Hmmmm.

I was being A.R. that the sealer was applied properly and had only considered the confined space scenario and not the asphyxiation. I may reconsider and pay the boys to do it. Tell Susan she can relax Bob.

The stuff was easy to apply, is non-toxic so no confined-space asphyxiation, and there's a sheen on the surfaces of the concrete tank when it's exposed to water which must be the "barrier".

One 5 gallon bucket easily covered our below ground cisterna with a lot left over so we applied it to the inside walls of a large 4-chamber concrete septic "thing" (I don't know the correct term for that 10 foot deep, cavernous monster- "Underground Apartments dwellings" maybe !)

Seems like good stuff.
