How are height and water movement related?
Slab height, neighboring surfaces and water movement should be assessed together. Ponding or water at a doorway does not point to a single cause, and lifting alone does not install drainage or guarantee that water problems will be cured.
What observations should you share?
- Where water appears after rain or regular use, and which slab or doorway it reaches.
- Accessible photos of the affected area, taken from a safe position.
- Whether water seems to pool, run toward the building or stay near the slab edge.
- Stay out of unsafe areas, and do not try to diagnose unseen pipes.
What belongs in the written plan?
- What the proposed lift is intended to change in the slab's height or level.
- Which water issues may remain after the lift, so you are not surprised later.
- Whether drainage installation, plumbing or structural repairs are needed, and if so, how they would be scoped separately.
