In areas with higher water tables or higher-pressure water intrusion, damp proofing will not cut it and true waterproofing will have to be used. Damp Proofing is a great, economical, solution for many below grade structures, particularly in northern climates where the only issue is ground moisture and not serious water intrusion.

Damp proof paint is specifically formulated to protect against damp interior walls. This type of paint can also be used as a primer, prior to painting with a decorative finish paint.
A quick reminder - damp proofing should NOT be used as an alternative to solving any underlying damp problems. Damp must be treated correctly before damp proofing paint is applied. Any areas of concern should be investigated by a professional. Damp proofing the interior basement walls is effective as it seals up any cracks or faults in the foundation that could be letting in water. It then prevents any moisture from reaching the basement floor. Often, you can use the membrane and tar method for the interior.
This is mainly due to their effectiveness in plugging up any cracks that could compromise the foundation and their ability to stick to various surfaces. Because various forms of damp proofing are only temporary, it may need to be done again in several years. Damp proofing is widely popular in drier climates, as there is a lack of moisture in the soil. Therefore, damp proofing would be sufficient.
That said, you should consider waterproofing for cooler climates and those who live on high water tables. When building a new home, it will be damp proofed by the builder. Damp proofing during construction will prevent any structural damage for several years. Even on new construction, after several years, the damp proofing will begin to fail. Many handy homeowners take the DIY approach, as it is a rather easy process to master. Contractors and builders both do damp proofing, as builders damp proof new construction, and contractors often damp proof when it begins to fail.
Because damp proofing is critical to the foundation of your home, many homeowners prefer to hire a licensed contractor for their damp proofing and waterproofing needs rather than take a DIY approach. Because damp proofing is a relatively easy task, many homeowners will damp proof their homes themselves.
There are many damp proof mixes and kits available for this very purpose. Because damp proofing is only temporary, your home will likely need to be damp proofed every years, as the adhesive materials will eventually wear down and become ineffective. The square footage of your home is one of the most significant aspects that affect cost.
The larger the perimeter of your foundation, the more expensive it will be due to material cost and labor. If you have existing damage on the foundation, this would have to be repaired before damp proofing, placing a significant increase on the price tag. Since there are various methods used, the one chosen affects the price. For example, a membrane often costs more than the spray substance method.
It is a thick paste that is squeezed with a sausage gun into a series of horizontal drill holes along the mortar course. Damp proofing rods are made of the same materials as the cream, in a hardened form. The rods are impregnated with a water repellant and installed in a similar way — by drilling holes in a mortar course to insert the rods. Once in place, the rods release their water-repellent active ingredients to spread along the mortar course.
Damp proof sheeting is a type of membrane used to prevent rising damp. In addition to protecting floor finishes and indoor air quality, this product also acts as a barrier to methane and radon gas. Historically, an inexpensive and common method was to spray tar on foundation walls and footing joints.
This is no longer recommended because the tar contains harmful VOCs and the material can become brittle and flake away over time. The best damp proofing material is completely inert, does not emit any dangerous VOCs, does not require investment in expensive spray equipment, installs in any weather tar cannot be applied in cold rain, snow, or sleet , installs quickly and efficiently, and lasts a long time.
Poly Wall waterproofing systems check all these boxes. The EPA recommends that masonry block walls be parged prior to applying any damp proof coating. As mentioned above, the IRC also requires that parging be damp proofed. The purpose of a retaining wall is to hold back the soil when there is a change in ground level.
