I need to build up the level of my concrete garage floor in the vicinity of the door, to remove a small inwards slope which starts just outside the garage. The added height will vary from about 35mm to a feather edge. This is to minimise water running past the seal on the door. The options I can think of are:
- Use concrete / mortar (+PVA?) to raise the level of the concrete (I am aware this will probably be too thin and may crack)
- Use epoxy mortar (very expensive even for small quantities)
- Floor levelling compound used dryish so that it doesn't level (probably only intended for internal use).
- Break up some of the existing concrete so the new concrete is reasonable thick. (more work).
Does anyone have any comments - I am seeking a reasonable, but not perfect result.
