damp underlay problems!

[jacquij]

I am having a problem with drying out a wet underlay...

I noticed that the carpet undeneath my chair etc in my back room was wet when i lifted it, it is a north facing room by the coldest corner i.e two external walls meeting with no radiator on either so I figured that it was condesnation - since i used to get that on the walls although bizarelly no longer.

Anyway I moved the furniture and lifted the carpet and the underlay was wet in about a 2 m by 1.5m area. i lifted back the carpet and the underlay, the underlay has been like that for about 10 days and hasn't seemed to dry out? I have been usinga small dehumidifier and also a little heater to help it snot budging though? any advise?

Also really wierdly where the carpet has folded over a liquid has just dripped from the corner - i thought it was more water but touching it it feels a bit oily or like there are small crystals in it - does anyone have any clue what this could be?

Any help gratefully receievd - sorry for the long post!

could it be an underground leakig pipe- central heating.

dehumidyfiers are good- leave off blow heaters though- don,t necessarily accelerate drying.a good breeze running through the area during daytime is good and inexpensive.

draw a chalk line around wet patch- after 24 hrs and periods thereafter,check if the patch is getting smaller.

would the crystallization suggest there is some salt in the water- just a guess.

best of luck

Is it a concrete floor or floorboards on joists?
