help w/ patio pitched incorrectly & rebuild
I have a small 16x16 patio slab in our backyard that is pitched towards my home. I am not sure how it's graded underneath. I am getting a slow water leak in my finished Rec room where the wall meets the floor when it rains. *It gets wet next in a 1-1/2 x 4 ft wide area. The drywall is not wet. *I have mulch next to homes foundation for landscaping and limestone rocks for edging. *I taped a plastic sheet over the patio slab towards my home and guess what. No water. It has to be coming in from underneath the step or on the corners somewhere.*
Should I remove the mulch and limestone rocks an add brown, compacted soil instead? *Mudjack the slab or remove, regrade and repour. Or should I install pavers instead?
