I don't know what type of tyvek you had but the normal "house wrap" tyvek will not leak. If it did every home in America would be wet rotted. This is the material that goes on to seal 90% of the homes in America.They depend on it not leaking, however, with that being said, there are different types of tyvek and they all probably are not water "proof" but then used for something different.Hope that helps...Happy Trekking...sabre11004
