I have an Outwell Hartford XL and it has never leaked,not even a little bit even in some really heavy rain. This is it's 6th summer. But yesterday we went back to the tent to find that the floor was sopping wet- it was as if the puddles underneath the tent were just seeping through.We were pitched on a bumpy forest site and there are definitley a few holes in the groundsheet,but that doesn't explain why the floor was wet allover.
Anyway,my question is what can I do about it? The rest of the tent is absolutely fine, but no good at all if the groundsheet isn't waterproof anymore.
