Due to already spongy floor patches throughout and a leaking dishwasher it looks like I need to replace approx 6sqm of t&g chipboard which feels like it's going through. The replacement will abutt 19mm chipboard but I plan to use ply and can only get 18mm ply, would you add shims only directly adjacent to the t&g or all over the ply? Also, is it worth using marine ply directly under the appliances and standard for the rest?
Additionally, the washing machine bounces round like its on a trampoline, floor shaking away. Is there a way to strengthen that area? Maybe doubling joists or putting cross pieces between them? The house has trench foundations so soil directly under, is it possible to build something up to provide a more stable base for that area or is that overkill?
Thanks
