Hi. Just back from a few days in Norfolk’s monsoon season. Five thunderstorms with torrential rain in four days. Lovely! Despite that we had a great trip and managed lots of sunshine and campfires between the downpours.
My question is: on saturated ground is it possible that water seeped up through three layers? 1. Vango footprint; 2. Vango tent floor (sewn in, approx 45 nights of careful use, no visible damage); 3. Bedroom pod floor, also sewn in.
I am wondering if we just had condensation dripping from the ceiling but it was only in one spot and seemed to be between the bedroom floor and the tent carpet we put under our SIMs.
Can a tent on very wet ground experience water coming upwards through the floor? It was only a couple of teaspoons worth and only in one spot but that was the boggiest corner.
Do you mean come over the top rim of the (bathtub style) groundsheet, or seeped up through the groundsheets?
There was a small dribble of water inside the bedroom and also a larger amount between the bedroom floor and the main tent floor. Although the ground was boggy by the end of the trip we weren’t pitched in a deep puddle.
Condensation was very heavy, heavier than I’ve ever experienced before due to having wet clothes/towels and just the general wetness of everything 🙄😂
Hasn’t put me off, just working out what went wrong and if it is avoidable in the future.
Regardless of the weather you must have all the vents open on a polyester tent in order to help reduce condensation. In some conditions it can be advantageous to unzip the door slightly and allow more ventilation.
Although water can eventually seep through a groundsheet if it is stood in a puddle, it is very unlikely based on your description that it was leakage, and almost 100% likely to have been condensation.
If your footprint is visible beyond the walls of your tent then rain and dew (on the outside walls of your tent) can run down and drip onto the footprint, run underneath between it and the tent groundsheet, and you are then virtually pitched in a lake! You then have cold water underneath the tent and warm air inside which are ideal conditions for condensation.
It takes a combination of wet and cold versus the warmth of the tent inside to create large amounts of condensation and in normal years those conditions aren't too bad and you may never experience it as bad as that again, but this summer we have had nothing but rain and damp for weeks...certainly in my area, so no doubt you have suffered more than usual.
This just happened to us too while camping. We used a footprint, a sewn-in groundsheet, a carpet and by the door a shaggy bathmat (to trap all the crud that folk walk in). It was a pretty wet week away and when packing we noticed that the carpet was damp-to wet as was the underneath of the bathmat. The reason was not condensation, it was water trapped between the SIG and the footprint, coming up as folk walk over that space. Clearly, what happened to you might be different, but to answer your question of can what pass upwards through three layers, yes it can.
