The damp proof course (D.P.C.) is measured in Sq m.(a) True(b) FalseI had been asked this question in an interview for internship.The question is from Jack Arched and Flat Terraced Roof topic in division Different Type Roofs, R.C.C of Civil Engineering Drawing

Answer»

Right option is (a) True

To explain I would say: General principles to be observed while laying damp proof course are:

i. The DPC should COVER full thickness of walls excluding rendering.

ii. The MORTAR bed upon which the DPC is to be laid should be made LEVEL, even and free from projections. Uneven base is likely to cause damage to DPC.

iii. When a horizontal DPC is to be continued up a vertical FACE a cement concrete fillet 75mm in radius should be provided at the junction prior to the treatment.

iv. Each DPC should be placed in correct relation to other DPC so as to ensure complete and continuous barrier to the passage of water from floors, walls or roof.
