How to Waterproof Your Basement in Just 3 Easy Steps

Take these 3 simple steps to waterproof your basement to prevent water from seeping into your house

It is not unusual for basements to become moist or wet. Rainwater or a leak in the basement walls and foundation are usually the main culprits behind a wet basement. Basement waterproofing can be carried out as a DIY project, depending on your expertise level and water issues.

What Causes a Wet Basement?

There are several common reasons why your basement may become wet:

  • Cracks in your home’s foundation allow water to seep through the basement walls and floors.
  • Inadequate drainage is a significant cause of wet basements. When rainwater is not properly directed away from your home, it can accumulate at the foundation and seep into the basement.
  • A poor drainage system, improperly installed or clogged gutters, or sloping around your home can lead to a wet basement.
  • If the land around your home slopes toward the foundation, water will flow toward the house and collect around the foundation.

Steps To Water Proof Your Basement

Here is how to waterproof your basement in 3 easy steps.

Step 1: Cleaning The Area

  • It is essential to start the waterproofing process with a clean area. First, remove any existing surface, wall, or floor coatings before applying waterproofing products. To remove old paint, use a wire brush or sandblaster, or seek advice from an expert on the best method for safe removal. Make sure you’re wearing proper protective gear. Next, use warm water, dish soap, and a scrub brush to remove dirt and dust.

Add bleach to the cleaning solution if mold is present. However, be careful not to mix bleach with any products containing ammonia. After washing, rinse the walls with warm water and allow everything to dry thoroughly before proceeding to the next step. Suppose there is efflorescence, a white, powdery, crystal-like powder on masonry walls. It should be removed using a commercial cleaner or muriatic acid, depending on the manufacturer’s instructions,

Step 2: Plug Holes and Seal Cracks

  • The next step is to address any holes or cracks in the area. For visible holes and larger cracks, hydraulic cement is the best product. This type of cement seals masonry cracks and holes to prevent water from passing through, even under pressure.

Hydraulic cement sets quickly, within 3-5 minutes, so planning to work quickly beforehand is essential. Smooth the cement with a trowel before it hardens. For more minor cracks, use a masonry crack filler. Seal openings like doors, windows, and window wells with caulk.

Step 3: Applying The Waterproof Coating

Choose a masonry waterproofing product that is effective and provides guaranteed protection against hydrostatic pressure and water seepage. First, however, It is necessary to apply the concrete sealer into the pores of the masonry with a quality nylon bristle brush or 3/4″ nap roller.

A minimum of two coats is required to ensure proper waterproofing. Be sure to read all manufacturer guidelines and instructions before applying. Furthermore, to prevent water from migrating down the exterior of the foundation and seeping through the seam, tape along the concrete floor 1 inch out from the base of the wall. Next, apply sealer on the walls, along the seam between the wall and the floor, and on the floor til the taped area.
