What is the best way of providing damp proof course in a building?

What is the best way of providing damp proof course in a building?

Methods of Damp Proof Course Installation in Construction The general principles to be observed while laying a damp proof course are: The DPC should cover the full thickness of the walls, excluding rendering. The mortar bed upon which the DPC is to be laid should be made level, even and free from projections.

What is the thickness of damp proof course?

The DPC should be of 40mm thickness and should be of uniform thickness. It should not be provided at the locations of the door openings. The top level of DPC should match with the planned finished floor level.

What is DPM in building construction?

A damp proof membrane (DPM) is a type of membrane material is used to prevent dampness from occurring through capillary action. It is often used underneath a concrete floor to stop it from gaining moisture.

What is the specification for damp proof course?

(a) The damp proof course may be of 2 cm thick layer of 1:2 cement and coarse sand mortar with standard water proofing compound at the rate of 1 kg per bag of cement. (b) The mixing, laying, curing, etc. shall be done in the same manner as above. The form or shuttering shall be 2 cm thick.

What is DPC in house building?

What is Damp Proof Course (DPC)? It is immensely important for all property owners to ensure that their property is protected with an effective damp proof course. The damp proof course prevents damp from the ground rising up the walls and damaging your property.

What is bituminous sheet waterproofing?

Bitumen, also known as asphalt, is a sticky, black and highly viscous liquid or semi-solid form of petroleum. Thanks to its waterproofing qualities, it is widely used in construction. Bituminous membranes are perfect for waterproofing roofs, basements, below-ground structures, bridges and other structures.

What is damp proof course (DPC)?

Home/ Building Technology Guide / Building Materials / Damp Proof Course (DPC) -Methods of DPC Installation in Construction. Damp proof course (DPC) is generally applied at basement levels which restricts the movement of moisture through walls and floors.

What are the different types of materials for damp proof course?

Types of Materials for Damp Proof Course. The materials commonly used to check dampness can be divided into the following three categories: Flexible Materials: Materials like bitumen felts (which may be hessian based or fiber/glass fiber based), plastic sheeting (polythene sheets) etc. Semi-rigid Materials: Materials like mastic, asphalt,…

How to use bitumen for DPC concrete?

In the case of a damp and humid atmosphere, a richer mix of concrete should be used. The concrete is further made dense by adding waterproofing materials like Pudlo, Impermo, Waterlock, etc. in its ingredients during the process of mixing. It is used to apply two coats of hot bitumen over the third surface of the concrete DPC.

What are the rigid materials used in DPC?

Some of the rigid materials used in DPC are: a. Rich Concrete Rich Concrete is the most commonly used material in DPC. Usually, rich concrete in the proportion 1:2:4 that is painted with two relative coats of hot bitumen is used for the horizontal damp proof course.
