Those mats are 15mm thick, weigh 40kg each (6′ x 3′) and are for gyms, so I was hoping they’d protect the floor. However, obviously not….
So I spent most of this afternoon repairing the floor and building a proper Olympic weights platform:
Using a very nifty tool I found recommended on STW, I cut out the collapsed bits of 18mm Ply:

The insulation under the Ply was crushed, so I replaced the duff section with some old fence posts to re-inforce that spot:

Covered it all in foil to keep a complete vapour barrier:

So I need something more robust under the bar:

Using 3 sheets of Ply, I made a 7′ x 6′ pad, with triple layer 18mm ply on the outer 2′ each side:

I cut up the 15mm rubber sheets to cover the edges and filled the middle with scraps of 18mm ply:

I put more rubber mat in the middle section with a final cover of Ply (as it gives better grip for shoes):

So there are now 4 layers of Ply and 1 layer of matting over the Celotex, which hopefully will last a bit longer…..
