Packers for bouncy joist?

[the_worrier]

My living room floor is suspended above the ground by around 1 metre on wooden joists which rest on a dwarf wall. I can access the space underneath easily enough by lifting a few floorboards.

In the doorway (threshold) between the living room and my kitchen/diner there is some bounce in the floor. Previously I have seen that the reason for the bounce is that the joist end has become loose. My plan is to crawl under and remove any loose material before packing the joist on the dwarf wall with slate packers taking care not to over pack and create a lifting of the floor.

What would you use and where would you source?

Mild steel Square packers, you'd need to buy assortment of them but they are cheap around 50p each and can be bought from any building fixings shop

Screwfix don’t stock. B&Q?

As you said yourself slate,maybe a bit of mastic/gripfill to stick it all together.A`slight` raising of the floor should not be noticeable
steel shims are another option too,maybe try ebay?

Probably be better going to a builders merchant rather than B & Q, make sure the fit is tight though as you could end up with them 'clapping' when walked upon if there's and play in them
