decking and dpm?

[Patho]

Hi all,
I've just laid some decking 8m * 4m, the ground that I've covered previously had some very triublesome weeds (mares horsetail) so I covered the ground in 1200 gauge dpm stapling it to the outside frame as i went, we've had rain for the past few days and I've realised that the water is slightly pooling underneath the decking all be it 6" underneath, hindsight says that I should have used landscape fabric, is there anything I can do to resolve this as I don't want to get the stale water smell at a later date or am I worrying over nothing?

thanks for any advice

poke holes in it?

and it will help to rot the framework as it sits in the pools of water. ARe you prepared to take the deckboards up to access it?

Deck boards are screwed down so remove a few to access the pools cut a section of dpm out and replace with the fabric held in place with gravel you don't want the support timbers sitting in water.

I have been contemplating this most of the day, and have come to the conclusion that if I remove two boards at intervals of about 6 boards then I should be able to cut out the dpm and replace with landscape fabric,

thanks for advice

back to decking for another hard days toil, took 3days to build using 1200 square headed decking screws , so hopefully I can replace the dpm within a day

thats the best bet, however its better to put the fabric directly under the boards rather than the framework, but that will entail taking the entire lot off!

I wouldn't totally object to removing the whole lot if I thought it was life or death for the decking, but the boards run across the width of the house for visual preference. So I'd rather that the weed suppressant barrier was lower to enable drain away between the boards (3mm gap between)

Is that standard practice for you? or only in this case?
