I've had a 4 x 5 M concrete base laid for a Log Cabin (Lugarde kit), but no DPM underneath, it sits on 5 piles.
I've built a berlin wall to retain soil on the high side (see pic) and dug a 4" drainage channel around the perimeter of the base. The base is slightly oversize (about 100/150mm all round) so there will be a lip. The roof overhang is 300mm so rain should drip outside the wall and drain shuttering.
The cabin walls will sit on 70 x 70mm tanalised bearers, and the internal floor the same. My intention is to use celotex and either T&G chipboard or ply for the floor.
My question is; How should I best damp proof the building? What would be the best arrangement of DPM and DPC?
As mentioned in a previous post (thanks for the replies) the base has a slight dip in the middle (20mm) so if water gets underneath it'll probably just sit there.
I'd be grateful for any suggestions as to the best solution.
