Hi
We are going to be forming a concrete base for our heating oil tank which will be right against the garage wall.
The base needs to be higher than the DPC in the garage wall and there is little or no room to pull the base out from the garage wall.
We plan to paint the affected area of the garage wall with liquid DPM from the ground level right up past the DPC to the top of the oil tank base.
We also plan to install a couple of layers of DPM from the ground level right up the wall following the liquid DPM.
I have attached a diagram.
Once the concrete base is poured the wall above will be finished with wet harling. At the bottom of the harling will be a bell cast which will through the rain water onto to top of the concrete base.
Will this plan ensure that no water gets into the wall from above or allow any water to rise up and breach the DPC.
Cheers.
