Basement waterproofing does not end with the installation of one, two, or even three waterproofing systems. It is a continuous process that requires patience and in some cases, vigilance. You have to remedy minor problems (like cracks in the basement wall) early on to prevent dampness and flooding in the basement.

Full awareness of some local geography (elevation of water tables, soil type, etc.) and house design will also aid you in determining the most suitable waterproofing system to protect your basement. This part of the book will discuss both solutions, preventions and a combination of both.

Floor Replacement Options

Some of you may have flooded basements already and we know how it feels to look at rotting floor boards. It's a mixture of anxiety and utter frustration. There are options that you can try if flooding has already caused significant damage to your basement's floor boards. The first option is carpet tiling. Anything synthetic is a good choice when it comes to replacing worn or rotted out basement flooring.

If no waterproofing system is in place, wooden walls and floor boards really don't stand a chance against the natural action of water and dampness. Combine these factors with the fact that basements are naturally humid and you have a recipe for disaster.

Your second option is vinyl tiles. If installed properly, vinyl tiles can last for years and will help keep your basement flooring dry. If your basement or crawl space's flooring is rough concrete, a good option would be to invest in false flooring.

To install false flooring, you will need two-inch polystyrene foam (for the entire basement), plywood, concrete fasteners, and floor cover (like vinyl tiles or synthetic carpeting). Measure your basement or crawl space first, then lay down the extruded polystyrene and add the plywood on top.

The plywood sheets should be at least 5/8 of an inch thick. Add the concrete fasteners before laying down the floor cover of your choice. False flooring is such an effective approach because the material literally separates all your stuff from water or dampness that may have seeped in from outside.

The concrete may crack and become flooded, but all your stuff will be safe because of the extruded polystyrene. With a synthetic floor covering, you have three layers of protection against moisture.

The Master Toolbox of Moisture Reduction Techniques

Below is a compilation of tips and tricks that I have learned or discovered throughout these years. Consider this section a toolbox of moisture/dampness reduction techniques.

Moisture is the number one enemy of any basement. This section will help you choose the best approach for your own basement by presenting different short-term and long-term solutions for basement dampness.

Apply Waterproof Membranes

Waterproof membranes are a must if you have concrete flooring in your basement or crawlspace.
The waterproof membrane goes in between the concrete and the actual flooring of the basement/crawlspace (wooden floor boards, synthetic carpet tiles, etc.).

When water from the ground seeps through tiny cracks in the concrete floor, the membrane will push back the water or moisture, preventing the water from rotting out the sub flooring. (Note: Waterproof membranes are liquid in form and can still be degraded by ground water over time.

Damp Coursing Is a Must

Musty, rotting basement walls are the stuff of nightmares. Avoid this scenario by applying waterproofing paint on at least two feet of your entire basement walling (measure from the floor level moving upward). This process is called "damp coursing" and is a tested solution -- it works every time!

Waterproof Membranes for Walls

Believe it or not, you can also apply liquid waterproof membranes on your walls. This is an excellent way to protect your basement's interior and is also cost effective, since you won't have to buy another interior sealant for your basement, as the membrane can be applied on both the floor and the walls.

Waterproof membranes, if given sufficient time to dry out and cure, can transform into a rock-hard layer that will prevent water from invading your basement all year round.
