Can you tell me where I would find statistics on how long it would take water to penitrate particle board. We have a kitchen cabinet unit and the tenant called saying the facuet was dripping and he had put a bucket under the drip, when he had called to inform us of the drip four days after the actual drip started! the next day I got there and the bucket had fallen through the board. I would be interested in any statistics you have on this.
