Hello folks,
I'm laying a patio which I wan to adjoin the house. To get the necessary slope (1:60) the surface of the patio will need to be less than 150mm from the dpc - about 100mm is the best I can do. Also the ground is heavy clay soil. The patio is to be 4m x 3m.
Here's my questions:
1) Is it "legal" to have less than 150mm (eg 100mm) below dpc if a linear drain is put between the patio and the house?
(as suggested in http://www.pavingexpert.com/dpc01.htm)
2) Do I need to build it on hardcore, or is sand enough?
Many thanks - and sorry for the novel!
