Hello all,
This is my first post so please go easy on me...
We moved into our current house a few years ago. The ground floor has wooden flooring on a concrete base. A few weeks ago we discovered a leak in the central heating system and discovered the pipes have been buried directly in the concrete.
Cut a long story short insurance is covering the replacement of the wooden flooring but having located and fixed one leak another one has occurred! (Apparently copper and concrete don't like each other)
I have therefore been advised that I should replace all the groundfloor pipework by digging trenches laying down a galvanised steel box and laying the pipes with insulation inside them before the new floor goes down.
Looking at the plans of the house it mentions the following for the floor construction:
1.5" sand & cement screed
3 coats of synthapruf
4" concrete 1:3:6
6" hardcore well consolidated & blinded with sand
I have two questions:
1. By digging to locate the initial leak we have gone down 3.5 odd inches. Can I assume we have already breached the DPM layer?
2. If we dig trenches to say 3.5 inches deep assuming we have breached the DPM - how do we re-establish it?
