Our house is on a concrete slab with wrap around porch. Our concrete porch inclines just a fraction back towards the house. When we have a rainstorm, rain goes toward the house and especially two exterior doors. We had a concrete professional put a decorative finish on our porch two years ago and requested he correct the water problem at the same time. He advised us that he could do both. Turns out the water problem was not corrected. So, we are stuck! Any suggestions would be much appreciated! Thanks!
