material: morningstar click lock solid bamboo floating on concrete slab moisture barrier/cork underlayment as per manu. recommendation installed by a friend in the carpentry trade. this floor was installed about 1.5 years ago. and these past few months we started seeing a gap which has now gotten to be about almost 1/2 wide. you can clearly see that the bamboo click lock tongue has broken and the floor has now separated. the material was purchased from everyone's FAVORITE supplier. lumber liquidators. i have filed a complaint , but have been playing phone tag with them for about 6 weeks now. and i cant simply pull the rest of the floor up to repair this center section , because alot of the end boards click lock joints were glued, so separating those boards will surly break the fragile click lock tongue has anyone seen a bamboo click lock floor fail like this? I thought i researched and bought a good product, but after these past few weeks of reading everyone's horror stories with bamboo, and with lumber liquidators I totally regret this purchase. this was installed in our first home, and now we have this horrendous gap right in the middle of our floor to look at... It couldn't be in a worse spot in the room!
