When you are planning to build a house with a basement, think beforehand how to protect it against water damage. Most cases (about 90%) of leaks and moisture in basements are a result of leaks in grade foundation walls. That happens because new build basement waterproofing measures haven’t been considered in advance.

If the foundation waterproofing has been done for the grade line only, topsoil and water-retaining mulch start covering the unprotected surface. There are some other flaws that can result in leaks, for example:

  • The basement wall gets wet because of sloping grades.
  • insufficient drainage
  • downspout drains that have been incorrectly installed
  • foundation sealant that has been incorrectly applied
  • lack of sealant above the grade line

Steps of New Basement Waterproofing

Everybody knows that if a basement retains damp and smells of mold, it is impossible to turn it into cozy and dry living space. If you intend to make a comfortable room in your new basement, consider it while investing in your new construction project. Plan the installation of the new foundation waterproofing in the basement to avoid the further problems with it.

Step 1. Exterior Waterproofing

  • Waterproofing or Damp Proofing
  • Sealing
  • Cementitious
  • Foundation Membrane
  • Bentonite Clay
  • Weeping Tiles
  • Excavation

Exterior (or external) waterproofing is meant to fix the leaky basement

The technology implies fixing these problems from the outside. The foundation is exposed and the necessary waterproofing technique. The materials are applied for making the solid waterproofing system. It will disperse or redirect any water or moist from the foundation walls.

Waterproofing or Damp Proofing?

If you live in the extremely humid area where soil moisture can penetrate into your basement even if there is not much rain or flooding, damp proofing will be the best option. First, the dirt should be removed from the area around the foundation. It will allow for the application of the damp proofing coating. Waterproofing works well for blocking moisture and heavier water leaks, such as rainstorms, flooding, or water runoff. It is widely used for poured foundations and cinder blocks because it is always a challenge to protect these thick materials from the moisture. Houses in the areas that suffer from a high water table need waterproofing badly.

There is a great variety in local climatic conditions. You need to consider them to make the right choice of waterproofing methods. Even in the areas where the climate is drier and water tables are lower, basements are built with the foundation walls that are 10 feet tall to prevent water infiltration. If your area shows the high figures of annual rainfall and higher water tables or lack of frost in the soil, consider using the slab-on-grade foundation. However, you need to protect such a foundation as well because moisture will permanently infiltrate through this slab from the ground.

Sealing

A basement sealer is always recommended to prevent the damage from leaking in your house foundation and in your household items.

Cementitious Products

These products are widely used as waterproofing materials. They can be found at any household items store, and such materials are easy to deal with while mixing and applying. To cope with these procedures more effectively, use a brush with a long handle. You will also need acrylic additive. That is a white milky substance which is mixed with the cementitious product and provides better bonding and more durable coating.

Foundation Membrane

External waterproofing membranes are applied to the foundation wall after excavating it. If the situation with the excess water is rather disastrous, the technology recommends installing a perforated drain pipe at the bottom of the trench and surrounding it with the washed stone. That will help to diminish the water flow and leaks.

Bentonite waterproofing

Bentonite is a type of clay. It has some special characteristic features that are used for a waterproofing membrane. They help binding, thickening, cohesion, and sealing. The color of the material is grey. When you work with it, the material looks like fine powder which resembles flour or cement. Bentonite waterproofing is usually applied below grade. When installed, it is hydrated by the soil moisture. That creates a strong barrier which can absorb and expel such chemicals as acids and salts (in case of using sodium bentonite) as well as water.

Weeping tiles

Tiles are actually not tiles but plastic pipes. They are perforated with small holes to be able to absorb water which usually leaks into the walls creating damp.

All these external waterproofing methods (either weeping tiles or installation of a membrane, for instance) require extensive excavation around the house.

Step 2. Interior Waterproofing

  • Foundation Coatings
  • Silicate Sealers
  • Basement Waterproofing Paint
  • Crawl Space Vapor Barrier
  • Epoxy Injection

Interior (or internal) basement waterproofing uses coatings

The method is effective when wetness is created by condensation. Normally, it is used when your home experiences minor dampness, though it is not quite efficient in case of large leaks. Concrete products for such waterproofing are the following ones:

Foundation Coatings

That is used as the most affordable and, actually, the best way to waterproof new foundation! A thick coat of concrete mix is applied to the interior walls. The premium foundation coating is a rubberized and cold-applied liquid for foundation waterproofing. It is a blend of rubber and some reinforcing fibers that resembles asphalt and provides a strong and flexible waterproof sealing.

Silicate Sealers are also known as densifiers of concrete

Penetrating into the concrete surface, they react chemically with other substances. It forms the solid barrier in the concrete pores made of calcium silicate hydrate (CSH). This substance does not change the color or look of the concrete surface, though it increases its strength by up to 45%. That can reduce dusting and the water and moisture moving through the concrete pores enhancing the durability of the entire base.

Basement Waterproofing Paint

The paint is, in fact, an acrylic paint product applied for basement waterproofing because it creates a perfect vapor barrier. Such waterproof paint can prevent water penetration into your basement. However, the paint can lose its qualities even within six months after its application if the exterior part of the foundation has not been waterproofed in a reliable way.

Crawl Space Vapor Barrier

The vapor barrier is one of the easiest and most effective solutions for prevention of moisture in the crawl space. Good-quality insulation can help avoid some health problems and structural damage. Such a barrier is simple to install and it maintains the good quality of the air inside your home. The crawlspace vapor barrier is also used to block insect infestation, mold growth, and it can sufficiently reduce your energy bills.

Epoxy Injection

An epoxy injection is used to prevent cracks and to avoid leaking. Epoxy is even stronger than concrete. Such an injection is applied under pressure to fix cracks that are 0.05 mm and more. The method is not applied when there are many active cracks and water leaking is sufficient and uncontrolled.

Why Should I Waterproof New Basement

The new basement waterproofing process can be rather expensive and time-consuming. However, you need to find an effective method to withstand water that wells up from the floor or leaky foundation walls. In the long run, that will save you a lot of costs and effort.

New Basement Waterproofing Cost

The entire process of basement waterproofing involves planning and preparation, first of all. Then, you will deal with sealing of the foundation and wall waterproofing with cement or other material. You may also need to install a perimeter drain or sump pump, to divert the downspout runoff from your foundation, or even to repair cracks, if any, with an epoxy injection. All these jobs are rather costly and time-consuming.
