Designing Your Own Bathroom Drainage System

Designing Your Own Bathroom Drainage System

A great bathroom calls for a reliable drainage system. However, designing it can often feel overwhelming. For it to work, you need to consider several factors, such as the layout of your bathroom, costs and benefits, and the type of drainage materials to use. So, you may feel tempted to hire someone to do it for you and get it over with. Doing so, however, may cost a lot of money, most especially if you have a unique bathroom layout.

To help you out, we’ve outlined some of the critical things you need to consider when designing your own bathroom drainage system.

Primary Vs. Secondary Sewer Connections

Bathroom drainage systems are usually split into two sections. Primary sewer connections are those that drain water directly to your central sewage system. They are the pipes hidden under your bathroom floor. On the other hand, secondary sewer connections are the drains that collect wastewaters from your bathroom fixtures like showers, sinks, and bathtubs. 

You need to understand the interactions between these two sections. Doing so will guide you on deciding stuff like the size of your pipes and the type of materials you will use. It can also help you find ways to minimize costs without sacrificing efficiency.  

Two Types Of Bathroom Drainage

There are two types of bathroom drainages you can choose for your bathroom. The first one would be traditional bathroom drains, while the second one would be linear drains. Traditional bathroom drains are the typical square or circle-shaped drains that you see in most houses. On the other hand, linear drains are newer technologies that use longer drain bases.

Both systems have pros and cons. Traditional drains are cheaper as they require less material. They, however, catch fewer gallons of water per minute, which may cause ponding or water pools. Linear drains, on the other hand, offer a more modern look and faster draining. They, however, often cost more. Some homeowners also report worse scumming with linear drains.

Fortunately, nothing limits you from using both drain types. For example, you can use linear drains for your shower. You can then use traditional drains for the other parts of your bathroom. With this combination, you can take advantage of the benefits of both drain types at the same time.

Ground Topography Of Your Lot

Your drainage system extends way beyond what you see inside your bathroom. For this reason, you should also consider inconspicuous factors such as the shape and features of your land.

The general design of your drainage should mimic the natural water morphology of your property. Doing so will allow you to take advantage of the shape of your property, reducing excavation costs. Furthermore, following natural depressions on your land will help you avoid backflows and water build-up in your system. 

Possible Underground Structures

If you are building a home in a city, or a pre-used lot, there is a chance that underground structures in it. These underground structures may include underground electricity cables, oil pipelines, gas lines, and communication cables. Unfortunately, you do not have the option to move service lines like these ones. So, your only option is to adjust your design based on them.

Failing to detect a single one of these lines will force you to go back to your drawing board; thus, wasting your precious time. This is why we recommend getting the help of a professional underground detection services. Professionals use high-tech equipment such as sonar devices to scan your lot as deeply as possible.

Waterproofing Your Bathroom

The perfect drainage system is worthless if water can find other ways to leak through your bathroom floor. If your upper floor bathrooms have inadequate waterproofing, you can expect water to collect in the crevices of your home. Even worse, these leaks may facilitate the growth of harmful molds, and, in some cases, compromise your home’s structure.

When designing your bathroom drainage system, always consider different methods to waterproof each section. Doing this step is essential as the primary and secondary sections of your drainage system may require varying degrees of waterproofing.

Getting the help of professional waterproofing companies can help you make sure that your drainage system works flawlessly.

Different Kinds Of Basement Molds

Different Kinds Of Basement Molds

Whenever we hear about mold infestations, we imagine homes being cordoned off, men hazmat suits, and people losing their properties. Although exaggerated, there is a reason for this panic towards these microscopic plants which can affect your health.

Several types of molds have been proven to be dangerous to humans. Many of them are seen to cause severe reactions, both with short and long-term exposure. So, as a home or property owner, you must know which molds you should always keep an eye on.

To help you out, our excellent waterproof specialists listed them down below. We also threw in some tips on how you can fight these pesky molds.

A list of the most common species of toxic molds:


This type of fungus proliferates in climate zones during spring and summers. It can cause allergic reactions and respiratory irritation to individuals with weak immunities. Its spores can easily be carried by the wind, thus spreading it within your home.

They are found in very humid places such as basements, crawl spaces, and kitchens. Other materials that Alternaria can grow on include cardboard, electric cables, textiles, and canvas materials.


Aspergillus is a relatively common type of mold. In fact, most of us breathe it every day without any severe reactions. However, if you have a compromised immune system, you should avoid places with a high concentration of Aspergillus. Aspergillosis is an infection due to the inhalation of this type of mold.


Chaetomium is a type of fungus under the Chaetomiaceae family. Its natural habitats include soil, air, and plant debris. It thrives in high moisture places such as flooded basements and wood boards. Hence, it shares the same environment with black molds, resulting in people confusing the two

Inhalation of Chaetomium spores may cause red, watery eyes and trouble breathing. Overexposure of immunocompromised individuals can also result in neurological damage and certain autoimmune diseases.


Fusarium is a genus of filamentous fungus. They are often found on soil and plant debris. They, however, can also grow on other suitable surfaces that are moist or wet. Besides respiratory diseases, this fungus is known to cause a severe eye infection named fusarium keratitis.


This fungus is famous for its contribution to the discovery of the drug penicillin. Although scientists can create drugs from it, Penicillium can still be dangerous in its fungiform. Inhaling its spores can cause bronchitis, asthma, and other respiratory problems.


Probably the most recognizable mold is the Stachybotrys. People commonly refer to it as the black mold. If there is a reason for the panic towards molds, then the Stachybotrys would be it. A person who inhales the spores of black mold can experience a wide range of symptoms and reactions.

These symptoms include diarrhea, memory loss, flu-like symptoms, headaches, and severe respiratory damage. The danger of black molds is most significant for children, people with asthma, and those with weak immune systems. If black mold is found, homeowners should immediately contact authorities and mold removal experts.

What to Do If You Suspect Your Property Has Toxic Mold

The first thing you should do if you suspect mold infestation in your home is to have specialists test your property. Doing so will make sure that there is an actual need to get mold removal services.

If the experts confirm your suspicion, look for a mold removal company for the specific type of mold you have. This part is vital as not all companies cater to all kinds of molds. Spores may also be found in the air of your home. If so, it would be best for you to stay somewhere else while the removal is ongoing.

After the removal of the molds, it is important to take steps to make sure that infestation doesn’t happen again. A waterproofing service can help you prevent dampness and moisture that molds love to grow in. Seattle Permadry Waterproofing offers excellent basement and crawl space waterproofing services.

Do I Need Drainage for My Driveway?

Do I Need Drainage for My Driveway?

Your driveway experience extreme wear and tear. So you should wonder once cracks start appearing on the surface. You’re probably wondering, “What does this have to do with needing drainage for my driveway?” The thing is, besides your car driving through it every day, your driveway experience just as much damage from something you would never expect, water.

If left on its own, water can erode the surface of your driveway, creating uneven surfaces or worse large cracks. The best way to prevent this issue is to plan ahead of it. The water management system of your home should include a well-designed driveways drainage system.

Why Should I Prevent Water Accumulation In My Driveway?

Most homeowners and business owners often disregard installing drainage systems to their driveways. The reason for this is that some of them are unable to see the damage a single puddle of water can do. However, this is the same reason many driveways last shorter that than they are made to be.

One example of a minor issue that may ultimately ruin your driveways is tiny cracks in your pavement. Concrete driveways often act like sponges that absorb considerable amounts of water whenever it rains. Although invisible, this accumulated water can expand and shatter your driveway when winter arrives.D

iscoloration is also a common problem of driveways that lack proper drainage systems. Accumulated water is often accompanied by dirt and other materials that can be absorbed by your pavement. Once absorbed, this dirt can stain your driveways, ruining the aesthetics of your home. For asphalts, accumulated rainwater can quickly discolor it over some time.

Another issue with letting water accumulate on your driveway is the growth of fungi, weeds, and sometimes mold. Some varieties of fungi can discolor your driveway. Weeds, on the other hand, are both an eyesore and damaging to your driveway. Weeds, although small, can force their way through cracks forcing the latter to widen.

Molds are the worst among the three. They grow in damp to wet surfaces causing impossible to remove stains. They are also a significant health threat, most especially to persons with compromised immunities or weak respiratory systems. Furthermore, if your driveway is close to your basement, the lack of drainage can also cause dampness on the latter. If there are two things that molds love the most, it would be moisture and darkness.

Components of Proper Driveway Drainage

Now that you are familiar with the most common reasons why you should install a drainage system to your driveway, you should now learn what you should consider making an excellent driveway drainage system. Here are the three things to consider when installing a proper drainage system:

The Shape Of Your Property

When constructing your drainage system, consider the shape, angle, and position of your property. You must know the height of your driveways. The reason for this is for you to prevent the mistake of directing run-off water towards your property.

You should also consider the location of your home to plan where to direct the exit of your drainage properly. One issue that can arise in not doing so is accidentally pointing your exit to your neighbor’s property. This mistake will not only get you tagged as a bad neighbor but also result in you spending money to reconstruct your drainage.

The Type Of Drainage to Use

There are several types of drainages that you can install in your driveway. Each of these types has its own pros and cons. The three most common types would be underground pipes, trenches, and channels.

Perforate pipes can be hidden underground to provide your home with a way to redirect water. A bonus point would be that, it being hidden, means that it does not affect the design of your home. Trenches, on the other hand, are simpler and easier to construct. However, they are often hard to design beautifully. Lastly, channels filled with rocks can both act as drainage and design of your lawn. If done improperly, however, it can result in smaller puddles that can eventually make things worse.

Constructing your driveway drainage can save you money. However, DIY projects often are of lower quality than getting a professional to do it for you.

What Are The Best Yard Drainage Solutions?

What Are The Best Yard Drainage Solutions?

Your front yard acts as an appetizer for your property. Being the first thing your visitors see, it can affect how they see you as a person. Considering all of these facts, a single misplaced puddle on your lawn can give the wrong vibes to people. Hence, homeowners like you must install effective yard drainage solutions.

Here are some easy ways you can improve your yard’s drainage:

Build A Simple Creek Bed

Creek beds are one of the easiest drainage systems to install. If done right, creek beds can also look amazing even when they dry out. Creek beds are often constructed with one end facing a water source like roof gutter pipes, and the other facing the lowest part of the property.

In simple words, its job is to direct water somewhere where it can’t do any damage. It can effectively prevent water puddles by giving the water an exit out of your yard. When building a creek bed, make sure that it is not directed to someone else’s property. Also, check your local public office to make sure that creek beds are legal in your area.

Beautify Your Yard With A Rain Garden

A rain garden is a section of your yard that is lower than its other parts and often enclosed by rocks and filled with plants. It acts as a catch-basin for rainwater what may otherwise turn into puddles. Rain gardens usually don’t collect water by themselves. So it is crucial to build it together with other water directing systems such as a creek bed.

When building a rain garden, it is ideal to choose native plants with deep roots and excellent water resistance. With a rain garden, you no longer have to worry about watering your plants as nature will do this for you. Beware, however, of grass overgrowth in your garden.

Use An Underground Drainage Pipe System

A drainage pipe system is a more modern approach to your yard drainage problems. Compared to the first two, a drainage pipe system uses materials not found in nature. To build your pipe drainage, position the inlet to a major source of water and place the outlet somewhere lower.

Ideal underground drainage should be sloped at least 1/8 inch per foot. Make sure also to cover the buried drainage with gravel to support it against any weight.

Construct A French Drain

A French drain is a level-up version of the drainage pipe system. Instead of using a smooth pipe, the French drain uses a perforated kind of pipes. This means that moisture stuck away from the inlet of the tube can still be drained. To make it even more effective, you can cover the buried pipe with gravel to make it easier to for water to enter.

Another difference between a French drain and a yard drainage pipe system is that the latter does not need an outlet. With it being surrounded by wholes, the water collected by it is evenly distributed into the soil it is buried on.

Find Someone Who Can Build You A Dry Well

A dry well is a relatively large whole on the ground used to collect rainwater to help disperse it on a single location. Special dry well barrels are specifically designed to do this job. They are built with heavy-duty plastic materials that make them immune to the environment.

A dry well requires a considerable amount of digging to construct. Without proper care, you can end up damaging your yard than helping it. Here at Permadry Waterproofing Seattle, we offer top-notch yard services to make your property look its best. We specialize in preventing water damage in properties, including preventing water puddles from accumulating and more. If you wish to learn more, call us now at (206) 309-5147.

What To Do When Basement Leaks After Rain?

What To Do When Basement Leaks After Rain?

A house’s basement can serve many purposes. You can use it to store things that you no longer use. If you have some extra funds, you can even set up a kickass living area for you and your family. Unfortunately, being located at the lowest part of your home, your basement is most susceptible to water leaks and flooding. Basement flooding can cause significant financial risk.

Luckily, you can tap the services of waterproofing companies like Permadry Waterproofing Seattle to help protect your basement from leaks. However, you may not always have funds to ask for expert help. In this case, you can apply some DIY waterproofing techniques instead. Here are some easy ways you can prevent leaks in your basement:

Locate And Repair Cracks In Your Foundations

Your foundation carries most of your home’s weight. Hence, it is unsurprising that some cracks may appear over time. Repairing your foundation can cost hundreds to thousands of dollars due to its importance to your home’s integrity. You can, however, use polyurethane injections as a temporary solution for this problem.

Polyurethane injections seal cracks tightly to prevent them from growing. It also prevents water from seeping through these cracks, avoiding further erosion of your foundation. After applying the injection, make sure to consult a foundation expert to assure the safety of your home.

Remove Any Debris In Your Eavestrough

Your eavestrough or gutter helps control the flow of rainwater from your roof. It prevents rain flow from damaging your walls and digging through your lawn. It also helps direct rainwater to proper drainages.

An unfortunate drawback of eavestroughs is that they easily gather debris like leaves and branches. A clogged gutter can cause water to back up and flow to places you least want them to. Overflowing water may also slowly dig through your foundation, which in turn may cause leaks in your basement.

After clearing any debris from your eavestrough, you should then prevent future clogs by adding a filter to it.  You can install or have someone install large-hole metal meshes to catch debris flowing to your gutter. Also, use larger drain pipes to reduce the possibility of leaves accumulating inside them.

Prevent Condensation In Your Water Pipes

Even without cracks, your water pipes can contribute to water leaks in your basement. When cold water flows through your water pipes, air condenses on the pipes’ surfaces. Only small amounts of moisture are produced this way. However, the scarce ventilation in your basement will prevent the water from re-evaporating. The best way for you to prevent pipe condensation is to insulate your pipes.

Inspect Your Sewers Regularly

Besides being extremely unsanitary, leaking sewers can cause the most damage in your basement. Make sure to check your sewer tanks and pipes at least once a year. If you live in a very old building, your inspections should be more common. You can also hire companies that offer high-tech sewer inspection services that can help you find invisible cracks.

Ask For Expert Help

Applying DIY preventive measures against basement leaks can save you hundreds of dollars. However, nothing beats knowing that your home is protected by expert waterproofing services.

Why Do You Need a Crawl Space Sump Pump?

As a SeaTac-area resident, you don’t need anyone to tell you that you live in one of the rainiest places in the continental United States. On average, Seattle enjoys — or perhaps endures — 152 rainy days per year.

With that much rainfall and the Olympic Peninsula’s high humidity levels, it’s no wonder homeowners experience constant issues like wet basements, damp crawl spaces and the occasional basement flood.

Sump pumps are one common solution homeowners employ to keep their basements dry. Typically, homeowners install sump pumps beneath their basement floors where water often collects. However, you can place sump pumps nearly anywhere water tends to accumulate — including inside your crawl spaces.

If you frequently deal with wet crawl spaces, keep reading. We’ll explain how sump pumps keep damp crawl spaces dry and what else you can do to keep your crawl spaces dry so that they don’t attract rats or create mold and property damage. read more…

Crawl Space Problems? Save Energy and Your Home With Concrete Encapsulation

Issues with crawl spaces in Washington State affect the homeowner, contractor, remodeler, and property manager.

Waterproof Your Foundation Now to Avoid Dealing With Flood Damage Later

Recently, Seattle and Tacoma residents and officials watched helplessly as torrential rains caused flooding in many neighborhoods. Parts of Washington saw rain and snow totals that were 200 to 600 percent over normal precipitation amounts. The fact is, homes all over the state are at risk of or already suffering flood damage.

Additionally, due to the increased chance of flooding in coastal areas across the US, the Federal Emergency Management Agency (FEMA) has redrawn flood maps. FEMA recently raised the base flood elevations in the Tacoma area by several feet, meaning a new area of homes along Washington’s shoreline are expected to be vulnerable to intermittent flooding.

No matter where you live in Washington, climate extremes and flood-plain changes are your signal to act now to flood-proof your home. read more…
