Used these , three months on, the rods look just the same, the mortar in my wall is still reading 33% on my meter, ( and this is in the summer months ) which is the maximum it will go to. I think I have been conned, big time. Thank god I only did a 10 foot interior wall, as a test before doing the whole house.
Hi mate Any change now? Did you seal the rods in the cement or silicone,only asking coz the fella who done this video didn’t and someone in the comment section said he can see a cream so guessing he didn’t seal them in either. Thanks
you might have moisture still trapped in the wall from before the rods where put in. If it was already at 33%, it would take months to dry out. Sounds like you didn't hack off the plaster and sand and cement it with a waterproofing admixture when you put the rods in.
I have recently used these for the first time. I was wondering if you know how the rods actually react when they get moist. I am seeing some white cream type seepage from some of the drilled holes and I assume this has to be from the rods. Do you know if this is how they chemically react?
my understanding is yes they react with moisture /damp and the cream fills all the pores and gaps and everything to create a barrier. there used to be a liquid version, might still be its been a while since ive used this stuff
I've got a DPC in but at a height of a about 150mm. I can go lower as you can where the damps settles below the membrane in the brick. Assuming if I can go lower, it's not an issue??
The 150mm is to protect from the splashback effect. DPC not only protects from rising damp, but also from rain. The gutters are supposed to protect most of the wall, but the lowest 150mm are still wet due to water splashing off of a surface. So it will get wet and then rise. You would think the DPC has failed or bridged, but it's just the surface being too close to the DPC.
I assume that at some stage rising damp was diagnosed. Who diagnosed it? Was it an independent damp surveyor, a damp proof installer, or just yourself? I ask because I am a structural engineer who sometimes gets involved in damp issues and although I do acknowledge that rising damp can arise, I have yet to come across a damp problem that is due to rising damp.
Whilst you have used to rods correctly pal that is only half the damp course.. the plaster needs to be removed to 500mm past any signs of damp, the substrate treated with a salt neutrilizer and re-render with a water resistant render.
