What Is Basement Waterproofing

Common Questions

What is basement waterproofing?

Basement waterproofing is a technique using materials used to prevent water from intruding into the basement of a house or building. There are two different types basement waterproofing.


There is INTERIOR Waterproofing, which uses membranes and French drains along foundation footings and steam walls of the basement. It encapsulates a basement from the outside.  At the side of the footings new drainage pipes are placed covered with P-gravel and drainage fabric, which redirect water to exterior by gravity or a sump pump. It is a very effective and cost efficient way to control water intrusions. Interior waterproofing can be done faster than exterior waterproofing.


Then there is Exterior Waterproofing which consists of excavating foundation walls to the bottom of the footings. Once the area is excavated, the walls are covered with exterior membranes, like Delta or Mira drains. These membranes expand drainage areas to all layers of a soil profile. The dry walls may also be sealed with waterproofing solution. At the side of the footings, new drainage pipes are placed covered with P-gravel and drainage fabric. Exterior waterproofing is the best route to go to prevent structural damage caused by water intrusion, but is more expansive, and causes damage to the surrounding landscaping, which requires a restoration afterwards.

Can mold cause health problems?

Mold can be a problem indoors when airborne mold spores land on a wet or damp spot and begin growing.  Many people report health problems related to molds.  Molds produce allergens and irritants, and sometimes toxic substances called mycotoxins.  Individuals sensitive to mold spores may have allergic respiratory reactions from inhalation – symptoms are similar to hay fever such as sneezing, runny nose and red eyes.  Molds can trigger asthma attacks in people with asthma who are sensitive to mold.

Touching mold may cause similar reactions and even skin rashes or dermatitis.  Allergic reactions to mold are common and symptoms can be immediate or delayed.  Mold exposure can affect allergic and non-allergic people alike with irritation to the eyes, skin, nose, throat, and lungs.  Mold exposure may stress the immune system and thus provide an avenue for opportunistic infections.  Other symptoms unrelated to inhalation or topical exposure are uncommon and individuals suspecting other complications from mold exposure should consult a medical health professional.  Additional resources are available with your state or local health department.

The key to mold control is moisture control.

  • You should routinely inspect your house for water leaks, don’t wait until the leak finds you.
  • Household water leaks should be fixed and any mold cleaned up promptly.
  • Once leaks are found, dry water-damaged items and areas within 24-48 hours to prevent mold growth.
