Mold Health Hazards

Excess moisture and lack of ventilation in the home can harbor toxins, allergens and also promote the growth of mold and mildew. Failure to deal with a moisture issue in your home can lead to structural damage, ruin appliances and other home goods, and make your family sick. In extreme cases, black mold poisoning can be fatal.

Symptoms of Black Mold Poisoning

Black mold spores can become airborne and a person exposed to black mold may experience flu-like symptoms, which might include:

Burning or sensitivity of the eyes

Difficulty focusing


Headache and fever



Sore throat


Skin irritations

Shortness of breath

Symptoms of Black Mold Poisoning

At the first sign of a mold (musty smell, water leaks, condensation, or visible growth), contact a basement waterproofing specialist for an in-house consultation. If black mold is detected, we recommend a qualified mold removal specialist who can deal with the issue promptly and appropriately.

Addressing Mold Issues

Hiring a professional basement waterproofing contractor to repair a foundation crack or a full-blown leak is only the first step in combatting the problem—a total solution includes first eliminating the source of moisture and then cleaning the mold, which should be handled by a mold remediation specialist.

Well, you could up the ante on that generator but, before you take out a second mortgage to pay for it, consider the much easier and more economical alternative of installing a battery backup sump pump.

Although most of us refer to “battery” backup sump pumps, there are actually two kinds – those that use a battery only and those that use an AC/DC power system. Here’s how they differ:

A battery-only backup sump pump is designed to step in when your primary sump pump fails due to a power outage. It takes over the task of removing storm water from the sump basin and, depending on the type of battery used, will run from 24 to 72 hours. These pumps are great for power outages and can save you not only the cost but the work and aggravation of repairing water damage in your basement.

An AC/DC backup sump pump will also function solely on battery power during an outage, just like the battery-only pump. However, the dual-power variety will also assist your primary pump when the volume of incoming water overwhelms its capacity and the power stays on. These pumps are great for sustained periods of rainy weather or mega-storms like last July’s. They also extend the life of your primary pump by preventing the frequent recycling that kills electric motors.

So, when you see those dark clouds gather and the cat’s hair is standing on end, think about what can happen to your basement while you’re running out to close the car windows. A backup sump pump can relieve you of one more worry, so why not set your mind at ease? At Worldwide Waterproofing, we’ve installed thousands of backup sump pumps and our customers can rest assured that a passing thunderstorm won’t endanger their basements.

Basement Wall Failure: Causes & Issues

How Moisture & Soil Composition Contribute To Foundation Failure

Foundation walls that fail can lead to a wide variety of issues for your home. The open pathways in the walls can be a pathway for flooding water, pests, odors, and humidity. Bowing walls can lead to cracks in drywall, loss of property value, and the potential collapse of the structure.

If your home is experiencing foundation damage or failure of any type, we can help!

What Causes Basement Wall Failure?

When external pressure on your foundation walls exceeds their capacity to resist it, they will begin to bow in the middle, tilt in along the top, and/or slide in along the bottom.

Foundation walls most commonly fail for two reasons:

Water flooding on muddy clay soils

Improper Drainage

Poor slope or drainage around a building causes surface water to drain away slowly, thereby increasing water infiltration next to the foundation.

Increased soil moisture conditions increase hydrostatic (water) pressures on basement walls.

If the combined hydrostatic pressure and earth pressure (exerted by the surrounding soil) on the wall exceed the wall's design capacity, the wall will crack, bow, lean, or shear.

This type of pressure may be partially reduced by proper grading of soils, maintaining gutters, and extending downspouts. However, any foundation damage should be professionally inspected.

dry, cracked clay soils

Expansive Clays

Clay soils are considered expansive when they have the capacity for extreme volume changes with fluctuations in water content. This most commonly occurs during the rainy seasons in the local areas.

In short, expansive clays swell when wetted and shrink when dried. Expansive, swelling clays against basement walls can exert lateral pressures on the walls of the magnitude of several tons per square foot!

This type of damage will only get worse as the foundation continues to buckle under the pressure, and is most cost-effectively dealt with during an early stage.

Horizontal Wall Cracks

Horizontal foundation wall cracks are potentially very serious problems that can sometimes lead to the complete failure of the foundation walls.

These cracks occur when pressure builds against the side walls and forces them inwards. Given time, this pressure can snap the walls, creating an enormous and devastating problem.

Foundation Wall Cracks

Foundation wall cracks can easily get worse if they're left untreated, especially in the case of cinder block wall foundations. Any crack or opening in the foundation at all can become a passageway for water to enter.

Because the foundation wall is literally cracked through, the gap will continue to worsen as the walls move and become influenced by pressure from outside the walls.

One crack in the foundation walls will lead to another, and no crack will ever improve on its own. All cracks should be repaired if they're allowing water through, and even a hairline crack can be evidence of a larger problem and should be inspected by a professional immediately.

Many options are available for bowing foundation walls (such as wall anchors) that will reinforce your wall, prevent the inward movement of the walls, and redistributing the load to where it can be better handled.

Planning for a basement remodeling job takes time, money, and patience. But one of the biggest mistakes that you can make is to begin the remodel process before a waterproofing inspection is performed by an expert.

Waterproofing a basement, installing extra sump pumps, and sealing basement walls before you commit to a remodeling job will save you unnecessary future distress.

For this reason, it is always recommended that you have a basement waterproofing expert inspect your basement before you consult general contractors about a basement remodel.

Why? Because what a basement waterproofing expert brings to the table is years of expertise and talent in determining current issues and warding off future problems. A general contractor wouldn't be looking for these types of situations, and they shouldn't be the only person you consult on what solutions work best.

Basement remodels, including adding extra living space and bedrooms, should involve a basement waterproofing expert. If you forgo communicating with a basement contractor before you begin your remodeling job, you could be in for a rude awakening later.

Similarly, you should always have a basement inspection done before you move anything of value into the basement.

Even if you don't have any plans to transform your basement into a second living room, and are simply going to use it for storage, a basement contractor should be on hand to identify trouble spots.

Here are some additional benefits of having a professional basement waterproofer inspect your basement for leaks and moisture problems.

Protection of Property: Basements usually contain more than leisure items. It is incredibly common for small and large appliances, like washers, dryers, and furnaces, to be kept in the basement. A waterproofing inspection ensures that these important items will not rust or succumb to potential moisture issues and suffer permanent damage. A basement waterproofing inspection is far less expensive than replacing a furnace.

Protection of Keepsakes: Some people use their basement as a storage area, which is completely fine. So even if you are planning a complete basement remodel, you might still use parts of the basement as a place to store keepsakes, family memories, and collectibles. When you allow a basement waterproofing expert to take a close look at your basement, you can rest assured that moisture won't become a future problem and that your belongings are safe and sound.

Protection of Family: If your plans are to transform an area of your basement into an additional bedroom or sleeping area, a waterproofing inspection is a must. Further, by contacting a waterproofing contractor previous to a remodel, you can find out the facts (and laws) on installing an egress window in your home. An egress window is, by law, required in a basement where living and sleeping areas will be. A basement waterproofing expert can help you determine where the best placement for an egress window will be.

Protection for Future Sales: A basement inspection isn't just a must for the current occupants. If you ever plan to sell your home, you might want to add equity by sealing basement walls. A moisture-proof basement adds valuable square footage to your home. A homebuyer interested in adding more space will want to know time tables on inspections. Have an expert inspect your basement today so that your selling process will run smoothly tomorrow.

A basement remodel isn't complete without the keen eye of a basement waterproofing contractor. Ensure that your next home improvement project is sound and secure by hiring a basement waterproofing contractor.

When we first became homeowners, we knew that certain pressures came with the job – paying the mortgage, fixing things that break or replacing things that really break. We probably didn’t think much about something called hydrostatic pressure, but many of us are dealing with its consequences.

Hydrostatic pressure is one of those fancy terms a basement waterproofing contractor may use to describe the source of water coming up through your basement floor. It sounds serious – and it is!

So, what is hydrostatic pressure, where does it come from, and how do you stop the rising water it produces from seeping onto your basement floor?

What’s a Water Table?

Any discussion of hydrostatic pressure must start with some information on the water table. Simply put, the water table isn’t furniture but the level of the water in the ground on which your home sits. There are a number of factors that affect the water table, with the most common being proximity to large bodies of water.

The frequency and intensity of rains also play a large role in determining the water table. And, if your home is built on the dense clay soil that is very common in the Maryland DC ,Virginia area, you are more prone to higher water levels due to clay’s lack of absorption.

A quick story on water tables: A contractor put an addition on his home in 10 years ago. He dug the basement for the addition one foot lower than the existing foundation and, no surprise, hit the water table. Mistakenly thinking it was no big deal, he continued with his project. Now, the two sump pumps in the addition run nonstop in the middle of winter, moving more than 135 GPM (gallons per minute) all the time. The moral of this story: Beware the water table!

Hydrostatic Pressure on the Rise

So, we have this body of water in the ground…and now it's raining. Every day. For a week. As the rain seeps into the ground, the water table rises because the ground is unable to soak up all the water. This rising water table creates hydrostatic pressure against your foundation and the pressurized water will find every little crack, chink and hole in your foundation walls and floor and make its way into your basement.

Time to Face the Facts

The fact that the basement waterproofing contractor is talking to you about hydrostatic pressure is a cause for concern because you probably have water coming up through the basement floor. So, what’s the solution? Unless the water is the result of a failed sump pump, it’s most likely that your home’s drain tiles have failed and will have to be repaired or replaced.
