My house has an abandoned concrete patio at ground level. Previous owner built a 12'x 12' wood deck 14" above the concrete patio. I have rain water getting in my basement where the concrete deck meets the house block wall. I have built a roof over the deck and fixes all gutter issues. I plan to remove a few decking boards, which are parallel to the house and repair the joint between the old concrete deck and the house concrete blocks. My alternatives are:
- Place mortar between the blocks and concrete deck
- Place mortar and lay a row of brick between the blocks and concrete deck
- Clean, apply silicone caulking between the blocks and concrete deck and put bricks on the caulking
- Clean, apply silicone caulking between the blocks and concrete deck and put vinyl siding angle between the blocks and ....This angle is 1.5" by 1.5" with a 90 degree angle that is rounded (radius).
