External damp-proof membranes are essentially a waterproof sheet of polyethylene that is placed over the surface of a foundation. Damp proofing does, however, effectively stop diffuse ground . Further, the American Concrete Institute (ACI 515.1) defines waterproofing as a treatment of a surface or structure to resist the passage of water under hydrostatic pressure, whereas damp proofing is defined as a treatment of a surface or structure to resist the passage of water in the absence of hydrostatic pressure. In short, the main difference is that dampproofing only retards moisture and it can't stop ahead of water bearing against the foundation, while waterproofing completely seals your foundation from moisture and liquid water. Waterproofing costs between $3 and $10 a sq.ft. 790-11 Hot Rubberized Asphalt. On the other hand, damp proofing only retards the progress of moisture, in absence of hydrostatic pressure.

Explore. ! Summary: 1. When it comes to damp proofing, there is a choice to be made between a liquid solution or a sheet membrane. The primary difference between waterproofing and damp proofing is that this membrane isn't expected to prevent penetration by standing water when hydrostatic pressure is present. Because the coating material used in damp proofing forms a membrane . External damp-proof membranes are less common today than they were in the mid-20th century because they have been replaced by bituminous or have had their role augmented by it. Some problems involves salt damp, lateral damp, rising damp & mould. A damp proof course, or DPC, is often placed to prevent water from rising. The reality of waterproofing vs. damproofing.

As a guideline, waterproofing is often needed for below-grade applications, whereas dampproofing is often satisfactory for above-grade applications. Basement and cellar waterproofing. 4. Damp proofing is the application that resists water passage with no hydro-static pressure. R406.1 Concrete and Masonry Foundation Dampproofing. In the context of below-grade protection, dampproofing is the treatment of a surface to make it resistant to the passage of humidity in the absence of hydrostatic pressure (e.g. The difference between damp proofing and waterproofing is how resistant they are to different types of water exposure. 88 Rubberized Waterproofing (Spray Grade) Dampproofing. Simply put, damp proofing can only keep out small amounts of moisture, whereas waterproofing completely seals the surface.

The intention of damp proofing is to prevent water vapor permeating the foundation which can result in condensation on the interior of the foundation walls. The primary difference between the two is that waterproofing can withstand hydrostatic pressure in addition to moisture control. Asian Paints SmartCare Damp Proof is a fiber reinforced elastomeric liquid applied waterproofing membrane for waterproofing of flat and sloping roofs. Damp proofing is tar based, while water proofing is rubber based. The damp-proofing process keeps out soil moisture, while waterproofing keeps out moisture in addition to liquid water. Whereas damp proofing only controls water vapour from the soil moisture and will not stop the inflow of liquid water. 3. Waterproofing is very similar to damp proofing, where it adds a layer of protection to the surface of your concrete. Thus, preventing the passing of moisture or water into interior spaces. It is also usually applied more thickly, typically up to 40 mils, which is about four times the thickness of damp proofing compounds.
