i want to do car porch tiling outside my nipah gate, however realize that the porch reaching to the road is slanting sideways, on the right is higher slope the way to the left front corner. The right cannot lower the ground else water cannot flow to the road. The left cannot make higher else it will be high hill slope for my car to drive in. If the car porch tiling do slope to the left front corner, the tiles might jack up at the one corner. My contractor also scratching head and propose to make the tile smaller.
How to make it a smooth slope?

i want to change my aluminium window frame rubber. somehow it looks it melted and is sticky. How?
