Downstairs in my house I've got a floating floor which consists of an inch or so of polystyrene over the substrate, damp proof membrane, and floating tongue and groove chipboard floor, then just lino on top. I've recently had a bit of plumbing work done and the guy has cut straight through a section of the floor. I don't know why he didn't try and lift the boards along their tongue and grooved joints - maybe it was easier for him to just cut them, or maybe he wanted to disturb the smallest area possible, as the sheets of chipboard seem large.
Anyway, as you'd expect, the floor has lost its structural rigidity in this section now. He used some glue where he cut the boards but this has just cracked and loosened as soon as it dried and the floor was walked on (it seemed a brittle no-more-nails style glue).
I'm now looking for ideas on what to do next. The glue he used can be raked out, so is there any better product that could be used? Or is there any other way to brace straight cut chipboards?
And on a side note, is this type of flooring typical of housing builds since the 1980's? (which is when mine was built). It's making me hanker after a 'proper' house with a concreted floor.
