Basement Waterproofing Hillsboro, Oregon

Water damage crawl space with blowers to dry it out

In order to make our home waterproof, we first must learn about basement waterproofing in Hillsboro, Oregon.

One method of waterproofing your basement involves placing a vapor barrier between the outside and inside of the basement. A vapor barrier acts as an insulator and absorbs all but the smallest amounts of moisture.

On the exterior, it is comparable to a plastic tent that is left unbroken and open. The vapor barrier prevents water from penetrating the interior of your basement. These systems can be installed by our professional water-proofers.

Our Hillsboro Waterproofing Contractors have been in the industry for many years. They have the skills and expertise to assess and diagnose exactly how to seal your concrete basement. 

Often times the best method is by waterproofing basement walls from inside. Our professionals also specialize in foundation leak repair for your home.

Don’t wait until it is too late and your basement is flooded and has extensive repairs needed. Call the best waterproofing company Hillsboro has to offer at 503-809-8200!


The process of waterproofing your basement:

Installing a vapor barrier prevents water from seeping into the basement while simultaneously protecting the interior of the basement from water damage.

The wall-to-wall diagonal water drain runs parallel to the walls and drains through the center of the basement. It connects to a vapor barrier that is installed at the second wall.

The water is directed away from the foundation and the walls of the basement by gravity. If any part of the vapor barrier is damaged, it can be replaced.

The second method of basement waterproofing involves installing a special waterproof membrane. There are different types of membranes available. Some are molded plastic sheets that are affixed to the outside of the walls or the bottom of the basement.

The interior of the mold sheet can overlap the exposed basement floor. This will create an extra waterproofing layer above the existing interior drain. Most of these layers are designed to resist mold and mildew.

The third method is using special mold-resistant paint. When water seeps into the basement, the paint will be penetrated and provide an extra layer of protection.

This will make the basement appear dry. We recommend that you use water-proof paint for basement floors and walls. This basement waterproofing Project requires some sanding and painting.

The fourth method is using a vapor barrier. It is effective. It creates an airtight seal on the exterior of the walls. Also, this process does not seem to work well with wet walls.

Last but not least, we recommend basement waterproofing through basement drain improvement. There are two main options. You can use an excavating machine to remove excess soil around the foundation walls or you can use a specialized sewer snake auger with a screen.

Basically, you create an effective seal around the exterior of the walls and then install drains that lead to the basement.

Basement waterproofing is a tedious process. First, we have to dig the basement. Second, we have to seal the basement, and third, waterproof the basement. Once we are all done, your house is safe from any sort of water penetration.

Whether your home needs a concrete waterproof sealer, a foundationcrack repair, or a wall sealer, you have come to the right place! Call us now and book your free no-obligation assessment with one of our skilled contractors.

Why basement waterproofing is so important? 

It can protect the structural integrity of your home. 

A proper waterproofing system will prevent water from reaching the interior of the house and causing structural damage or leaks. 

Waterproofing your basement provides added protection against mold and mildew, which are two of the main culprits of basement flooding.

Prevention of basement flooding reduces the chances of structural damage, leaks, or a basement floor condition that may lead to more serious issues.

Can I install my own basement waterproofing system? 

A good way to learn about the process is to ask one of our professionals for some help. 

You should never attempt to do any kind of basement waterproofing by yourself. It is too complex and if you don’t know what you’re doing, it can be very dangerous.

What are the benefits of basement waterproofing systems? One benefit is that basements allow for a more comfortable home. 

If your basement is constantly wet, then you will have a difficult time enjoying your basement space. 

Another major benefit is that a dry and usable basement will increase the value of your home.

There are additional benefits as well, including reduced mold growth in the basement, improved energy efficiency, and a reduction in the cost of insurance claims. 

Water damage accounts for about one-fifth of all insurance claims made by homeowners.

What are the costs of basement waterproofing systems? 

Some of the costs associated with waterproofing your basement may include the price of the materials needed as well as the labor that is needed to do the job. 

The price of waterproofing materials can vary depending on the type of materials that are used.

Basements that are not waterproofed cause a variety of problems for the people who live in them. 

When the job is done right, basements provide improved indoor air quality, which in turn can improve your overall health. 

Basement waterproofing systems help to prevent mold from growing, which can be very hazardous. 

Finally, once your basement is waterproofed, you can enjoy all the beautiful features that made your house special.

It is always best to catch any sort of water penetration issues early as it is less costly. The longer you wait to think that the problem will fix itself, the bigger the damages grow. 

Cracks in your foundation, nonfunctional sump pumps, and insufficient waterproofing barriers won’t fix themselves on their own.

If you are tired of feeling the dampness in the air and smelling the mold and mildew, now is the time to act! All these factors are enough to avoid your home getting damaged further and decreasing its value. 

Now might be the time to consider basement waterproofing with our Hillsboro Waterproofing Company.

What Causes Sinking Crawl Spaces? 

There are several contributing factors to the sagging of indoor crawl spaces. These factors include structural damage, deteriorating structure, improper design, pest infestation, and weathering. 

All of these factors have the potential to dramatically change the appearance and usability of your crawl space.

The structural integrity of your crawl space will directly impact the overall look and feel of your home. For example, your foundation will need to be in decent shape. 

Poor foundation strength can cause subsidence and cracks in the floor and walls. If the foundation is not sound there will be a decrease in the structural load on your floor. 

This in turn can force weight to shift to other areas of the floor such as the ceiling, causing the joist to buckle and fail. 

This can result in floor buckling, structural weakening, buckling of wall frames, and weakening of the floor system itself.

The first way you can deal with your crawlspace moisture issue is with a dehumidifier. Why a dehumidifier? 

Well, most people understand the benefits of a dehumidifier – it helps keep a home or business from experiencing excess moisture in the air.

In addition to this, a dehumidifier can help remove excess moisture from crawlspaces by removing humidity. 

This will help you lower the water damage in your home from structural moisture, thus making your foundation more comfortable.

Sealing your vents will prevent moisture from getting into the space, and will help you keep the space dry. 

For your crawlspace, there’s one simple solution. Damp-proof membrane tape is the easiest, most effective, and least expensive way to seal your vents.

Improper waterproofing and drainage are also the primary culprits when it comes to causing sagging and sinking of a crawl space. 

Water that seeps into your crawl space will eventually find its way to the exterior environment, possibly causing dampness and moisture buildup that can promote mold and mildew growth. 

The moisture that seeps in can also deteriorate the structural integrity of the floor, which can lead to buckling and failure. 

As an added issue, improper crawl space waterproofing can allow rainwater to seep below the surface of the concrete, causing the same issue above.

There are several solutions to these problems, including external pressure from the ground or water pressure from underground pipes. 

External pressure will cause the ground to bulge out, creating sufficient downward. Unfortunately, there is no way to stop water from penetrating through soil or rock. 

External pressure alone can make your siding and wood framing crack, split, and buckle.

Proper waterproofing of a crawl space begins with an evaluation of the soil under your siding material. A proper waterproofing solution must also include materials that repel water, such as polyethylene sheeting. 

Impervious materials will withstand pressure to prevent structural damage but will not prevent water from penetrating. 

For this reason, impervious materials are often not used in basement remodels, even though they can be easily installed on the outside of the home.

Finally, many people are surprised to learn that what causes sagging and sinking crawl spaces is the expansion and contraction of the house itself. 

The moisture from inside the house will tend to rise above the surface it is leaking through, while cold air will push moisture toward the outer walls of the home. 

The waterproofing solution may also include coatings to prevent mold from forming.

Our skilled waterproofing contractors have many years of experience in this industry. We are dependable, trustworthy, and efficient to take on any size project. You will always get the best and most affordable solutions for all your waterproofing needs.

Whether a leaking basement, foundation cracks, or subsidence, most homeowners do not realize why a foundation must be repaired quickly and properly.

Most often, they make the mistake of waiting until the situation has become severe enough to justify an extensive search for the root cause.

In most cases, a foundation leak or other problem will only become more problematic as time passes because of the accumulation of sediment underneath the surface.

A slow breakdown of a foundation will result in the long-term removal of the standing structure itself. For these reasons, it is vital to know when to seek emergency foundation repair assistance from a professional foundation repair specialist.

Why a foundation must be repaired quickly is because of the potential for hydrostatic pressure to build up. Hydrostatic pressure occurs when the volume of groundwater above a structure exceeds the volume of soil surrounding the foundation.

When a foundation’s volume decreases because of sagging or subsidence, hydrostatic pressure can increase, resulting in noticeable movement or cracks.

These cracks can allow dirt, debris, and moisture to enter the interior of the foundation or utility system and contaminate the drinking supply.

Many times, the hydrostatic pressure is the result of improper grading of a foundation. Improper grading can allow the soil to settle into the structure, creating pockets and outlets where water can accumulate.

Underground water pressure can also be the result of a subsidence event, which may result from heavy rainfall or from plant roots draining upward into the soil around the house.

Regardless of the cause, both of these situations present significant dangers that must be addressed.

How does a leak in a foundation occur? The answer varies greatly, but in most cases, the source of the leak is groundwater or possibly a subsided water pipe. Leaking pipes are the most common cause of hydrostatic damage in structures.

They can be detected by checking the exterior of any basement window, checking for small gaps where water is leaking.

Most leaks can be traced back to either a septic tank or a storm-water drain. If a pipe in the plumbing system or a manhole can be found, foundation repair should be initiated to prevent additional damage.

How does a leak in a foundation affect the drinking supply? The majority of leaks are the result of improper drainage. A utility system can contain contaminants that will cause symptoms similar to those found in tap water, including odor, taste, and smell.

If left undetected, the accumulated contaminants will eventually cause damage to the supply infrastructure, including the pipes and equipment.

How is a foundation affected by changes in elevation? Groundwater levels can vary tremendously from area to area. A slight change in elevation can make drastic differences in hydrostatic pressure.

As water levels rise, so does hydrostatic pressure along with the roots. When it is high enough, leaks in a foundation can occur. When rain occurs after the initial rainfall, the extra water created as a result of the excess precipitation may cause additional pressure.

No matter the cause of the foundation leaks, calling one of our professionals sooner than later will save you a lot of money. Assessing the issue early and repairing it will put your mind at ease as well as your home being safe.


Replacing the old sump pump in a basement

A basement waterproofing system, including sump pump systems, can prevent the damage caused by a flooded basement. 

While a flooded basement poses serious dangers, it’s even worse to have no protection for your valuable possessions.

Waterproofing will help prevent damage done by flooding as well as prevent water damage from outside the home.

Homeowners who live in areas that receive heavy rainfall should install a sump pump as soon as possible. These systems are especially beneficial for basement owners who use the basement for storage. A pump will help prevent flooding.

Protecting your home from the outside in is equally important. Wet areas can be a breeding ground for mold and other harmful insects and pests. This often occurs around sinks, plumbing fixtures, and hot water heaters.

To prevent the spread of harmful organisms, these areas must be sealed off. Properly installed drainage systems will allow water to flow away from the home.

The benefits of sump pump systems are certainly undeniable. They provide safety and lessen the damage that could occur from an overflowing toilet or other water infiltrations.

Having a good sump pump system helps drain water away from a foundation. The sump pump basin allows the water to collect, then the sump pump discharges or sends the water out either to a dry well or storm drain. 

The main thing is to ensure all water is routed away from the structure. These systems are important as it helps to relieve hydro-static pressure from around the home’s foundation.

When you have a basement, you need to be careful. Any water that has penetrated should be drained as soon as possible. Have our team install sump pump systems will help you keep your basement dry and can help it stay free of mold and mildew.

The process involves a pump that is able to remove liquid quickly, and this helps to keep it from stagnating.

The system requires power but you can choose to have a solar-powered sump pump. There are also battery backup sump pumps. The battery backup systems are useful in situations where you may not be able to get electricity or a power source for a while.

They provide a backup power source so that your sump pump will work even if you are without electricity. We have the knowledge to install them for you so pick up the phone and call us today!
