Reworked Coach briefcase. 30 years old.

What’s the best product for keeping it nice and supple??

Connoloys, chosen by Mr Rolls and Mr Royce ?

Big slab on sidewalk. Heavy rain washed out fill, slab sagged 2-3 cm and cracked.

Trying to lift it and shore it up. Ideas?

Pry up with a long pry bar and wood blocks. Try to work slowly across the full width otherwise the slab may break from suction underneath.
Block up the slab to proper height and start packing sand underneath.
Tap on the slab to check for hollow sound (voids under slab).

Or just breakup the old slab and pour all new. This might be easier.

Could lift it with lever but bricks just tamped down dirt

I’m thinking lift and wedge up the pack in stone under width

Plan B - use expanding window sealer in can to hold up

New timber looks nice.

Shuttle lines on the Beetle do not… blew PS vomit on way back from train

Get bigger blocks to pry against. Like a 2 foot 2x10.
I have seen You tube video of using expanding foam to lift a slab like this. I think it took a lot and you had to dig under the slab to get in place. Maybe they drilled injection holes in the slab. I don't remember.

PS…6x6 by 8 foot are about the biggest sticks I can handle solo…pick and load onto car

There are companies now that can lift a good sized slab with an epoxy foam. They drill one or more small holes and inject the foam slowly, gradually raising the slab.

We had this done on an entry walk where 80 yr old tree roots had lifted the slab up and snapped it, making a 2” lip. It joined right back up flush.
He filled the holes with drilled concrete crumbs mixed in and they disappeared.

I need some kind of lifting clevis - with a strong eye hook.

can lift these slabs with my engine crane, the shore up with stone. EZPZ

Where to find this, I wonder?

Looks to me like great chance of breaking the edge of the slab. Concrete has poor bending strength without rebar. It might work better to place about 4 anchor bolts with eyes in the slab face and then lift from multiple points.
You get MVS bonus points for engine lift plan.
