I am about to start renovating a 300 yr old cottage, neadless to say the existing floors and wall have no DPC and suffers from damp, the exterior ground level is approx 150mm above the existing concrete slab on one side of the house and above level on the other.
1st of all i plan to dig a trench to foundation level around the property to allow the walls to start and dry out, this will be back filled to a lower level once a french drain is installed. Is this the correct thing to do?
2nd i plan to remove the existing concrete floor and re-lay with insulation and DPM, i am unsure on where to tie in the DPM from the floor once layed as there is no existing DPC in the brick work. Is it acceptable to terminate the DPM at the edges of the floor? Im guessing not.
Is it possible to install a retrospective DPC (not chemical) into the brickwork?
Any advise will be much appreciated.
