Choosing a brush/roll on foundation water proofer?
Hello,
I will be breaking ground on a new house in the next few months. One of the last details I have left to figure out is choosing a brush/roll on foundation waterproofer. The house is a 30′ x 60′ one story rectangle. Part of the house will be slab (music studio) the rest will be sealed crawl space. It will all be on a 12″x24″ continuous footer with 8″ block on top. The slab will be poured inside the block wall perimeter. (not a mono slab) The site is about a 5% grade on a hill top with some exposed rock. I anticipate getting to bedrock with the footer on the high side. I will be installing a foundation drain system all the way around per the specs on this site. I will also be sure to have the site graded properly and run my gutter water away from the house. I have decided on a roll/brush on waterproofer as the final part of the system, but I am having a hard time choosing a product. In doing research I think a polymer-modified water-based asphalt material will be best for my needs, but i am open to suggestions. Does anyone have any recommendations or experience with such a product? Brand / supplier? Obviously I want to get this right the first time. I am also all ears on any other advice on the subject.
Thanks in advance for any and all of your help.

Spray on the asphalt emulsion sealer. It's faster and gets into irregularities in the concrete much better than a roller or brush.
One caution on the water-based asphalt coatings: We had it sprayed on during a bit of wacky weather--a week of cold (just above freezing) followed by a very warm, humid day, when it was sprayed on. What happens to cold concrete on a warm humid day? Condensation. So instead of the coating drying, it get wetter and sloughed off. Then it rained and made a mess. So make sure you have weather conditions that promise the dew point will be lower than the temperature of the concrete for ~24 hours after or rolling on the coating.
Joe,
用于基础的喷涂或刷涂涂层被认为是潮湿的，而不是防水。如果您有良好的漏斗和带有粒状，可自由排水材料的回填，这些涂料很好（特别是对于爬行空间基础）。
If you were building a basement (especially one that might be finished some day), you would probably want to graduate from a dampproofing system to a waterproofing system.
