Not exactly sure which forum this should go into since it kind of covers several. I bought a house last July and had no problem till this December when we got nailed with a week long monsoon. The house has a sun room that was built onto the back of the house and it sets right on the patio concrete. It is Astro-Turfed instead of carpet. The rain has seeped through where the wall meets the patio and got some stuff wet that we had setting on the floor. Is there a way to water proof the bottom of the wall or seal it or something?
