basement finishing

I recently had the basement walls in my house patched and touched up.. I am going to put up drywall after the basement is waterproofed.
I asked the concrete guy if I need to paint over the walls with a sealer or drylock. He told me that I didn't have to, his concrete work is sealer enough. But he told me definitley do not use drylock on the inside of a basement because it will just trap moisture in the wall and cause it deteriorate, and the concrete will breakdown behind the concrete and turn to sand and crack over years.
I have been reading articles on putting drywall up in basements, and they say to put up a vapor barrier and insulation. Also, to wash down the walls with muriatic acid and paint with Glidden basement paint (the most mentioned brand.)
Is this the way to go before putting up the wood frame and drywall? Is what the concrete guy said about drylock pretty true?
The basement waterproof company has this thermal barrier they can put up that goes into their system that will drain away moisture and water into their system in case anything comes through the wall, but it is an extra $600. I think that is exhorbatent for just a foil/plastic covering.

That has definitely NOT been my experience. Once you stop any possible seepage from the outside, DryLoc is a great coating and much better than a plastic vapor barrier. DryLoc is still the best stuff out there IMO (be sure to have cans shaken as it has solids). I have seen simple vapor barriers develop condensation between the wall and plastic then leak down and stink, DryLoc will not allow that. Insulation is optional because below 48 inches or so the year round temp will not vary much. I would get more opinoins, but this guy seems to have a sale motive. I can honestly say that my DryLoc'ed basement feels as comfortable as the upstairs, as long as you have heat and (more importantly) plenty of cold air return vents, no mustiness whatsoever.

having been thru the basement water hassle, the interior french draoin is the way to go:)
what are you spending on the overal remodel? Myself I would drylock paint then for 600 bucks add the plastic barrier to prevent damage to interior finishes. I would use moisture resistant drywall too.
Does your basement have a ingress egress window or direct door to outside? Add either call it a legal bedroom increases resale value of home:)
Incidently the interior french drain with drilled holes into a block bottoms for drainage means no volume of water can get trapped behind the drylock paint, the added plastic is excellent to minimize soil moisture and condensation in walls from migrating ito your new finished space

thanks for replys...
I have a poured basement foundation.. so, the basement waterproof company will not be drilling holes in it for drainage.
