Lift and Level Heavy Stone Slabs With a Hay Hook

A hay hook gives you a handle on a big stone slab, so you can lift an edge, prop it, and fix the base underneath — without ever putting fingers under the stone.

The Problem

Fixing lippage on a big stone slab — one edge sitting higher than its neighbor — means lifting a stone that can run seven feet long, adding base material underneath, and setting it back down. Done by hand, that's fingers under a slab heavy enough to crush them, and a lot of awkward shoving to move the stone around at all. Large slabs have no grip: no edge to grab, nowhere safe to hold.

The Technique

  1. Set the point of a hay hook under the low or high edge of the slab and lift with your legs. The hook is the handle the stone doesn't have.
  2. Prop the raised edge — a rubber mallet wedged underneath works — so you're not holding the weight while you work.
  3. Add gravel under the low side and spread it the full length of the lifted edge.
  4. Take the weight back on the hook, brace the slab against your knee, pull the prop, and lower the stone down.
  5. Tamp the slab with the rubber mallet and check the edges against the neighboring stones. Repeat until the lippage is gone.
Safety note: The whole point of the hook is keeping fingers out from under the stone — don't defeat it by reaching under to sweep gravel while the slab is only propped on a mallet handle. Lift with your legs, keep your feet clear of the drop zone, and work from the side, not the end the stone would fall toward.
