I have not used this group before, but am looking for some advice if
possible? Any help would be most appreciated...
Two and a half years ago I had a 30sq metre engineered board wooden
floor laid in my lounger/diner by a local professional flooring centre
(I am based in Brighton, UK). The plank consists of a 8mm layer of
solid Jatoba (Brazilian Cherry) wood on top of a 18mm engineered
multiplex board. The brand is Multigarant (www.multigarant.co.uk) and
purports to be of the very highest quality (it wan't cheap!).
The floor is laid over a thin fibrous insulation layer on top of
concrete sub-floor. The plank is finished with oil.
Within only a couple of days of the floor being laid, we would hear
loud 'snaps' and very fine hairline cracks were appearing across the
floor (barely visible to the human eye). We were told that this was
normal - that the wood was just acclimatising and that the cracks
A year on in 2005, more and more hairline cracks had appeared and in a
few planks, had developed into open cracks of approximately 1mm in
width. The manufacturer was called to our house, assessed the floor and
told us that Jatoba is a very hard and therefore brittle wood and that
such cracking is normal, but was unlikely to get any worse.
Again, we have waited another year and the splitting is getting
progressively worse. On some planks it actually looks as if the Jatoba
layer is coming up from the board to which it is glued. Many cracks run
the entire length of the board.
I am now concerned that my floor is in a permanent and unstoppable
Does anyone have experience with Jatoba flooring? Is this usual
behaviour for this wood? My understanding was that an engineered board
should be extremely stable and that, regardless of the wood, this
should not happen.
Any advice or tales of similar experiences would be greatly
