Damp Proof Course Clause Samples
The Damp Proof Course clause specifies the requirement for installing a barrier within a building's structure to prevent moisture from rising through walls and floors. Typically, this involves the use of impermeable materials such as bitumen, plastic, or slate, which are integrated at a certain level in masonry construction. By mandating the inclusion and proper placement of a damp proof course, this clause helps protect the building from structural damage and health issues caused by dampness, ensuring long-term durability and habitability.
Damp Proof Course. Damp proof course shall either be with cement concrete or with cement mortar of specified thickness as mentioned in the relevant item of schedule. Damp proof course shall not be carried across doorways. It shall be laid for all walls except verandah retaining wall or for particular wall only directed by the Engineer-in-charge. It shall be laid flush with floor level or as instructed by the Engineer-in-charge. Damp proof course with cement concrete shall be of 25 or 38 mm thick in cement concrete M15/M20 as specified using 12mm. and down size aggregate well rammed and smoothened with trowel. It will be kept wet for 40 hours and after it has dried, two coats of hot bitumen shall be applied over it and allowed it to dry after which sand shall be sprinkled over it. Damp proof course with cement mortar shall be 12 or 20 mm thick in cement mortar 1:3 well mixed with crude oil at 5% by weight of cement used.
Damp Proof Course. 5.1 Laying of vertical and horizontal damp proof course is to be in accordance with the regulations laid down by the Sanitary Authorities. The horizontal damp proof courses on walls are to consist of a mixture of pitch and sand applied hot.
5.2 The vertical damp proof membrane shall consist of 3mm thick water proofing membrane as specified under specifications for Roofing Works. The dpm shall be carried 150mm into the surrounding walls over the horizontal dpc (laps at joints shall not be measured extra).
