exterior waterproofing... worth it?
we are about to embark on our tear down/ re build. quick history. Kansas City area, 9' poured concrete walls. drain tile to sump pit, gravel backfill 12" to 18" out from wall. new footers down to virgin soil. We will eventually finish the basement, plan on 2" xps on interior walls (down to footers before slab is poured)
I have asked for exterior waterproofing, not damp proofing. it would be a sprayed on membrane (Impax?) or similar.
worth it or a waste without bubble membrane? Lot has good drainage and downspouts will be buried to daylight downhill, 6" gutters.
