A cleat on my boat was torn off by the winter weather. There is a layer of wood smushed inside the deck between the laminates, into which water had penetrated around the bolts, causing rot.

I dug out as much as I could of the rotted wood and filled in the gap with fibreglass and polyester. Will add gelcoat later

Got confirmation that the apartment floor is a concrete concrete floor, but it is not entirely clear if the fault is something that has developed over time or if it was always like this. Regardless, it is likely stable and we just evened it out with floor underlayment (my father wanted to help me with this job).

To compensate for the broken lateral seams we used a funny tool which makes slots at the end of the boards where "joining biscuits" can be glued in between the boards.

We also moved the differently coloured boards under where the furniture will be. Now I just have to put the kitchen back together.

This apartment floor has developed an issue where a part of it sinks a few millimeters when stepped on and gaps have developed as a result.

Unfortunately it's a kitchen so I had to take the kitchen furniture apart and also unfortunately they are the old kind which is glued together. I am able to non-destructively open the longitudinal seams but the lateral seams all break so I will need to do some router work or something to save enough floor boards for the reconstruction.

I haven't determined the root cause of the issue but I hope it can be diagnosed and fixed from the crawlspace. The access hatch is guarded by a swarm of bees but they're the peaceful kind so I hope they will let me through if I'm careful
