Does Waterproofing a Basement Add Value?

Before starting any sort of project around the house there are a couple of questions every homeowner wants to ask themselves. The first question typically revolves around affordability relative to what will be gained from the Improvement.

The average homeowner, for instance, cannot afford a huge spray water feature in their front yard that would be at home on a Town Square. Sure, it would be beautiful and a real talking point, but for the average homeowner it would be prohibitively expensive, and probably damaged the resale value of the house.

However there are certain kinds of improvements and upgrades that should happen in your house as soon as they are affordable.

One of these no-brainer improvements is waterproofing a basement.

Waterproofing a basement is a no-brainer

Keeping water out of your basement is important for many reasons.

First and foremost wet basement is a place where mold can grow. Mold in the air of your home can cause allergic reactions or even worse effects on breathing and your body. Mold ca n even render your home unlivable.

A second reason to keep water out of your basement, is that water often comes through cracks or weaknesses in the foundation. so at the first sight of water one concern should be stopping the water, and the other concern should be making sure your foundation is sturdy and stable. Water doesn’t mean your house will fall down but left untreated it can contribute to the quicker demise of your biggest investment.

And a third important reason to waterproof your basement is to get it ready for an upgrade.

Remodeling your basement is a good investment

According to general estimates, remodeling your basement to add new living space and useful room, is  one of the better Investments you can make in your house.

It is estimated that in resale value alone, you recover about 70% of your investment in your basement remodel.  This means a $2,000 investment in your basement will likely get you about $1,400 in resale value, and a $10,000  investment would net you $7,000.

Of course, a remodel of any space typically isn’t done solely thinking about the resale value. This is true about the basement as well. For many people, a basement represents 1/4 to 1/3 of the entire space in their house. Converting that to useful space such as a den, TV room, or spare bedroom can make your house more welcoming, spacious. In all, a happier place to live.

And in order to be remodeled, it must first be waterproofed.

What better investment is there than that?

Commercial Waterproofing Products: Waterproof Membranes

When gearing up for your next construction product, you will want to consider the wide range of commercial waterproofing products available to pick the perfect option for your project.

While each of these products does what it was designed to do – keep out water and moisture – it is important to choose the right product for the specific job. This involves taking into consideration the location, depth, accessibility, and amount of water that the surface will be exposed to when the work is completed.

With so many different options, and so many different companies with their own proprietary lines of these products, one could be forgiven for being confused or overwhelmed by the options.

For this reason, we offer a light introduction to different commercial waterproofing products. One common type of waterproofing product is waterproof membranes.

Here are some products you might consider for your next major project.

Waterproof membranes

Waterproof membranes are separate materials that are designed to be attached to your structure, usually entirely below grade, to keep out water. They come in many different types and have different primary materials.

Some of these membranes are rubberized, providing an impermeable non-porous surface that works in applications where there is likely to be less compression and movement. These are placed on the foundation in the way you might put on a raincoat to go outside in the rain (though you might use less spray adhesive!)

Some waterproof membranes contain clay or similar materials that help absorb water without passing it through to the structure. This loose material, sandwiched between semi-permeable layers, allows for a more dynamic response to water below the surface. These filler ingredients can dry to allow the building to breath and contribute to evaporation. However, they are designed to self-seal when the conditions demand it.

Still other waterproof membranes are made of first use or recycled plastics. In many cases, these can be specially formed to not only keep water away from your foundation, but to direct or carry water away from it.

Some of these products can contribute to the LEED score of your building, as well as providing a lifetime warranty and guarantee against water invading your major investment.

Why do so many contractors protect their foundations with ShockWave Drainage Board?

At Mar-Flex, we have been producing quality lines of waterproofing products for years. We occasionally get asked which are our favorite lines.

And of course, to us, waterproofing products are like our children, and we love them all equally.

But for the most common applications, we find our technicians and our customers turning time and again to our ShockWave drainage boards. Why are they trusted so deeply?

We think there are three primary reasons.

ShockWave drainage board protects from an impressive amount of water

ShockWave drainage board’s most impressive statistic reveals how well it does the thing it is built to do: handle water.

ShockWave can soak up over 100 gallons of water per hour per linear foot of drainage board. 101.11 per hour, to be precise.

This helps protect your foundation – and your investment – against the equivalent of a stream running into your foundation. Knowing that our drainage board can handle this amount of water, which is unusually large, means that our customers know they can count on ShockWave to deliver the expected results in normal circumstances for the life of their investment.

ShockWave drainage board is virtually crush-proof

Of course, When you put drainage board on the outside of your foundation and then backfill tons of clay and dirt against it, you need to know that it will retain its strength and vibrancy over time.

So we designed Shockwave to be virtually crushproof. Let’s get to the numbers:

ShockWave can withstand up to 283.72 psi while still humming along, doing its water work. This is the equivalent of running a bulldozer across the ShockWave surface. This amount of weight and concentrated pressure would STILL not damage ShockWave drainage board.

You can be sure that your building demands will not diminish its effectiveness.

ShockWave drainage board adds to your LEED score

And here’s the kicker for many contractors. Sure, it handles more water than any other drainage board. Sure it is essentially crush-proof and …

It is meticulously constructed from 100% post-consumer recycled materials.

So, it does everything you could want, and using it actually increases your LEED rating, making it easier to reach your project’s goals. Not many waterproofing options can do that.

It’s clear that so many contractors rely on ShockWave drainage board because of its unparalleled strength, effectiveness, and LEED rating.

The real question is, why would someone choose anything else?

Get the Facts on Waterproofing Membranes

When you are working to waterproof your foundation,  you will come across a lot of proposed solutions and materials. Paints, caulks, and even concrete backfills can all be part of a comprehensive  waterproofing solution for your building’s basement.

Waterproofing membranes also need to be in the conversation.

Cost-effective and practical, waterproofing membranes offer a wide range of solutions including eco-friendly options that might even boost your LEED scores.

Here are some different options for you to consider for your next building or waterproofing project.

Drainage boards

One popular product that accompanies a waterproofing membrane is a drainage board. Fastened to the outside of your foundation below grade or ground level, drainage boards encourage water to move down away from your foundation instead of remaining pressed up against the concrete.

By moving the water away, your concrete is protected from having to do the work it was never designed to do.  Water sitting next to concrete will eventually permeate the concrete.

Waterproofing boards like the Mar-flex Shockwave drainage board have several important features which make them durable. First, they help move the water down and away from the foundation instead of holding it. Second, they are inert and don’t interact chemically with the soil around them, so they last a long time. Finally, they resist pressure from water and soil, retaining their drainage properties over time as the construction settles.


Drainage boards are an inexpensive partner for a waterproofing membrane. You should consider this for your next build. They are available in different model and price ranges.

Waterproofing Membranes

Waterproofing membranes can come in different forms. Some are fastened to the wall in panels, and others are sprayed into place. Either way, They offered the same great protection for your foundation by completely repelling all the water that comes against them.

The last barrier between the outside and your concrete when you’re building a home, office or other structure, is a waterproofing membrane.

When you pair a quality membrane, like the Mar-flex 5000, with drainage board, you can get a 60 year guarantee that your foundation will be protected from groundwater.

An advantage of waterproofing membranes like the TopGun WB Waterbased Membrane is that they can be sprayed over any clean, dry, sound substrate, and offer a lifetime of protection with a Limited-Lifetime warranty.

What is “Relative” Humidity?

We have all heard the term relative humidity before. We know that it means something about how much water vapor is in the air.

And we know that relative humidity is important especially inside a building where we want to keep mold and other contaminants to a minimum.

But what is “relative” humidity, exactly? What is it relative to? And what does it mean to us individually?

The air we breathe is more than just air

We know that the air is far more than just oxygen. The atmosphere and air we breathe holds much more than just one gas. It holds a mix of Oxygen, Nitrogen, Carbon Monoxide, Carbon Dioxide, and lots of others, in a mix that our lungs are used to sorting through. Our sensitive lungs can filter out their favorite candy from this Halloween grab bag of ingredients.

But also suspended in the air is a host of minor and major pollutants, including pollen, dust, and mold. And also, there is water vapor in the air, and that causes a problem.

The problem with humidity

Humidity over 70% supports and carries a whole boatload of allergens, irritants, and contaminants. It carries more pollen, more dust, more smoke, and of course, more mold. All of these wreak havoc on your lungs, making them work harder in an effort to reject them.

Individuals with asthma know that humidity means asthma attacks because of these pollutants and irritants.

Humidity makes these problems worse, so we work to keep it at an acceptable level, usually no higher than 60%

Relative humidity, defined

But what is relative humidity?

Well it turns out that air can hold different amounts of water at different temperatures. The warmer the air is the more water that it can hold. Colder air can hold less water vapor.

So the word “relative”  doesn’t mean it is compared to other times, it means that the humidity is compared to other temperatures.

So a “relative humidity” of 60% can feel quite different, and represent different amounts of water vapor in the air, based on the actual temperature.

A relative humidity of 60% when it is 60 degrees is very different from a relative humidity of 60% when it is 90 degrees. It represents far more actual vapor in the air at the warmer temperatures.

Of course, since indoor temperatures are usually highly regulated, this doesn’t mean too much of a difference inside, but whenever the inside air feels humid, you should grow concerned about the presence of mold and other contaminants.

What is Hydrostatic Pressure?

When you are looking to waterproof an existing or new building you are likely to come across the term ”hydrostatic pressure”. It sounds very scientific and complex. Hydro definitely means “water”, but what’s with “static”?

The term is easily understood, but the concept is a bedeviling problem for builders and engineers.

Hydrostatic pressure is, in its simplest form. The pressure that water places against everything else around it.

It causes problems in building, for reasons explained below, yet is a necessary feature of our water systems and water pressure in our homes.

Hydrostatic pressure can be the enemy

In building, one of the first and biggest problems to solve is how to keep your foundation dry, and to keep water away.

One of the great problems is caused by hydrostatic pressure.

The concept can be as complex as this, as described at

Hydrostatic pressure is the pressure that is exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity. Hydrostatic pressure increases in proportion to depth measured from the surface because of the increasing weight of fluid exerting downward force from above.

However, the concept is as simple as this: the further underground your building meets with water, the more pressure that water is placing against your walls. This is mostly explained by gravity, but also by other forces.

The best waterproofing plans for new construction and existing construction involve reducing hydrostatic pressure by directing water away from your foundation every way possible.

Hydrostatic pressure can be a friend

Hydrostatic pressure isn’t just for forcing water into your foundation, however.

Mankind learned a long time ago about the concept, and we have harnessed it to create … water pressure.

By utilizing tanks raised high above our communities and buildings, we have created a system that allows water to flow freely into our sinks, toilets, and showers. We simply pump the water up into the local water tower, and let hydrostatic pressure – also known as gravity – do the work from there.

You can see that hydrostatic pressure is an important concept to understand, whether it is working for you or against you.

Mar-Flex waterproofing offers a range of solutions designed to keep your foundation dry at whatever depth your plans require.

What is A Raft Foundation?

Builders employ a wide range of methods to keep their foundation safe. Experienced construction designers know that a dry foundation is necessary for creating a building that will be problem-free for generations.

There are lots of ways to achieve the goal of keeping your foundation dry. A rare but effective method of building a foundation that also helps keep it dry in certain soils is to create a raft foundation.

When should you choose a raft foundation

A raft foundation is not always the best foundation choice. Under most normal soil conditions, a regular poured foundation will be suitable for construction of even the tallest building.

If, however, you are building on weak soil that might give way under the full weight of your building, a raft foundation is the right answer.

It works in these conditions because the raft foundation is one large, flat surface on which you place the entire building. The flat, open surface of the “raft” or mat works to distribute the weight over the entire surface of the foundation. By doing this, the weight on any one given spot is reduced.

By distributing this weight evenly, no one spot carries a great weight. Instead, the building weight is distributed and thus it is less prone to shift, drop, or settle.

What is a raft foundation, exactly?

The raft foundation works as the name implies. Think of a raft of the sort you might use to escape from a desert island. It is a flat surface upon which everything else is built.

It is not like a building constructed on pilings, footings or columns of wood or concrete which only make contact on certain points of the surface below.

The flat surface is its own full surface to build on, but not to drill through or otherwise breach.

It lays on the excavated flat surface at the base of the building site. Once it is waterproofed and poured into place, everything else is constructed on top of it.

A raft foundation doesn’t float, and for this reason it’s best to think of it as a mat foundation, in that it lays there, and everything else happens on top of it.

A raft foundation is not necessarily used for the purpose of waterproofing, though it also comes up in waterproofing conversations. The point of choosing this foundation type is to create the safest, most secure foundation on loose soil.
