We used this for the subfloor in the house we built on a 1970's mobile home chassis. We had a long period of rain after the subfloor was installed but before the house was dried in. This material performed well, remained almost perfectly flat and well-aligned. Only had to be sanded in a couple of places. It holds screws firmly in place to prevent squeaky floors.
