Basement Waterproofing – Ultimate Guide

Basement Waterproofing involves techniques and materials used to prevent water from penetrating the basement of any structure, building, house. Waterproofing a basement that is below ground level can require the certain aspects of sealant materials, the installation of drains and sump pumps and more.

In Scientific terms Waterproofing Basement can be referred to as the formation of an impervious barrier, which is designed to prevent water entering or escaping from various sections of building structures.

Before you start waterproofing the basement walls, may them be interior basement waterproofing or exterior basement waterproofing consider this :

What Causes Basement Moisture?

Major issues for Basement Moisture are Improper Soil and Drainage Systems, Poorly Installed Maintained Gutters, Improper Slope, Hydrostatic Pressure and Condensation, etc. Preventing all these is the aim of installing basement waterproofing.

Improper Soil and Drainage Systems

When rain and groundwater cannot drain away properly it makes its way into the basement. Improper soil and poor drainage systems are main reasons of basement wetness. If water isn’t directed away from the home, it will accumulate around the foundation on which the house is build.

Poorly Installed and Maintained Gutters

Gutters are intended to channel rainwater away from the building foundation. If they are improperly installed or too clogged, water will drain around your foundation. Instead it should not even get around.

Improper Slope

The ground around your foundation should have a slope away from your structure, not towards it. If the slope is wrong, water will accumulate near the foundation, rather than running away from it.

Hydrostatic Pressure:

Hydrostatic pressure occurs when water gets collected around the foundation of the building. As gravity pushes down on that water, it will try to escape, in an effort to relieve that pressure. The water will force its way through any cracks in your basement walls and floors.

Now, once we know What Causes Basement Moisture? We can move the next process.

Ways of basement waterproofing

  1. Interior sealants
  2. Interior water drainage
  3. Exterior basement waterproofing

  5. Foundation crack injections

Interior sealants basement waterproofing

In poured concrete foundations, cracks and pipe penetrations are the most common entry points for seepage. These openings can be sealed from the interior.

Epoxies, which are strong adhesives, or urethanes can be pressure injected into the openings, thus penetrating the foundation through to the exterior and cutting off the path of the seepage.

Interior water drainage basement waterproofing

These methods are often used after an existing problem has been identified. This can include sealants and coatings, as well as methods to prevent condensation. A French drain, PVC pipe, or a patented drainage system is installed in the newly-made channel. The installed drain is covered with new cement.

Exterior basement waterproofing basement waterproofing

The exterior basement waterproofing method is designed to prevent water from causing any major structural damage to the building, using polymers and membranes to coat the exterior basement walls.

Interior basement waterproofing basement waterproofing

Interior basement waterproofing using coatings is effective where condensation is the main source of wetness. It is also effective if the problem has minor dampness. 

Foundation crack injections basement waterproofing

Foundation crack injections are used when poured concrete foundations crack either from a settlement or the expansion and contraction of the concrete. Epoxy crack injections are typically used for structural purposes while hydrophobic or hydrophilic polyurethane injections are used to seal cracks to prevent penetration of moisture or water.

Things to avoid during Waterproofing Basement Walls

During a rainy season, a crack in a basement wall can allow water inside, but before you seek to repair the crack, remove all the water from the floor. We would recommend you to not work in rainy season. Working in a flooding basement increases the risk of electrical shock or electrocution.

You should turn off the power to the basement, and then use a utility pump (with extension cords that reaches an upstairs outlet) to get rid of the water. The pump will discharge the water to the surface of your yard via a garden hose.

When the basement is water-free, proceed with inspecting, fixing, and effectively waterproofing the basement walls.
