I have a new house, it's now almost two years old. Last year I bought
RadonSeal to waterproof my basement. I applied a number of coats
carefully to all parts of the concrete floor and walls. Well, we had
some record rainfall this week here in Boston and I've had 3 inches of
water come into my basement every day. I can see timy bubbles coming
out of the concrete. Is it gases trapped in the concrete or some
chemical reaction?

Anyhow, I'd love to hear about a real sealant that works.

If you could actually "seal" the water out, it would buckle your walls. Be
glad you have failed.
If this is a recurring problem, you need a sump pump.
