Can sparks install electro osmisis?

Gingernuts31

For anyone who is familiar with the osmisis for damp proofing do you think its suitable for a sparks to install it or does it have to be a damp proofing contractor? I know the contractor will prob know more about the after work of installing the osmisis but just to install it I mean.

I would prefer to use a contractor who is trained to install it, I do have one and have specified them a number of times and have always used damproofing contractors. They are not a wiring instalation, the only electrical power need is from a 12v transformer and you can plug that in yourself!!

Was reading the instructions on the net alright and it doesn't look difficult at all except they don't specify some items like how long to bend the wire to make the anodes, or how far apart to place them. I know it depends on the area you are installing. I was quoted 1,300 provided I removed the plaster from the wall prior to installation and im guessing he wanted the plaster removed to put up the tanking material?

Theres no tanking, the wire is run around the walls continuously and every 300mm or so a hole is drilled into the wall and a loop of the copper wire put it. You get it replastered afterwards.

So no waterproof membrane or anything just replastered? How long before replastering cause my walls are pretty bad and they will need time to dry out before replastering?

By the sounds of it gingernuts you need a specialiat out to look at it. Electro osmotic damproofing stops rising damp, if your ground level externally is higher than your floor levels internally electromostic may not be suitable every situation is different so get someone to look at it and advise you.

I know what your saying but it is rising damp as the plaster is coming away from the wall and hollow to knock at, plus issue with mould due to poor ventilation. The sitting room which is the worst has a suspended wooden floor so the vents under that are above the ground level outside so to me that would suggest the ground level outside is lower than the floor. Just measured all the rooms height going from floor to ceiling starting with sitting room and all are the same so im guessing floor level is the same in all affected rooms, would you agree? I know I need a PVS to stop the mould but thats seperate from the osmisis.

+1 with no.6 re specialist before you spend on EO

I know your both right just 1300 spodolies and I have to remove the plaster is a bit off putting :eek:.

Get a specialist to look at it before you remove any plaster. My advice is do it right at whatever it costs and forget about it, cut a few corners to save a few euros now and live to regret it.

Yes, get a specialist. Its not a magic cure. In effect, it is an electric dpc, no more, no less. So if your problem will be cured by the introduction of a dpc, it should be a good fix however there are many issues that wont be cured in this manner. You need a detailed inpection and you dont want this done by anyone associated with any damp proofing companies for obvious reasons.
