Do Laundries Need Waterproofing? Act Fast Now!

A laundry room is an essential part of any home, but it’s also a space that is prone to water damage. With the constant use of washing machines and dryers, spills, leaks, and humidity, it’s no wonder that many homeowners wonder if they need to waterproof their laundry rooms. Is it Necessary?

A Laundry does need waterproofing to protect your home from water damage. By investing in waterproofing, you can extend the life of your appliances, prevent water damage, and increase the value of your property. It’s a small investment that can greatly impact your home.

To help you make an informed decision, this post gathers insights from various homeowners and experts on the best ways to waterproof your laundry room floor, offering practical solutions for your home improvement needs.

Why is Waterproofing Required in the Laundry Room?

A laundry room is an area of the home that is often overlooked when it comes to waterproofing. Water leaks are common in the laundry, just as they are in the bathroom and kitchen. Most households use the laundry every day to wash their clothes. It accounts for more than 23% of average household water use and is the home’s third most water-intensive space.

Due to the significant amount of water utilized, proper drainage and protection of surrounding surfaces are crucial in case of any water flow issues. Laundry rooms can become damp due to frequent water usage and machine-generated moisture.

So, waterproofing the laundry room is a practical solution to prevent overflows and leaks that could cause drainage problems for the home’s walls and floors.

Moreover, the moisture from the laundry can create the perfect environment for mold to grow. Waterproofing can help prevent mold growth and protect your family from the harmful effects of mold.

Waterproofing regulations apply to the foundation and certain parts of the flooring. Effective moisture management is crucial since water damage can cause significant and lasting structural damage to the property, making it unsafe. If not addressed promptly, it can be challenging to maintain.

What Happens if the Laundry is not Waterproofed?

You risk water damage from occurring if your laundry is not waterproofed. Laundry rooms often have water leaks and pipe bursts. The pipes connected to your washing machine should have valves that stop water if a pipe bursts, but sometimes these valves don’t work or are missing. Also, pipes in the walls can leak slowly without you noticing.

When water seeps behind walls and beneath floors, it can cause:

• Wooden studs are weakened and rust away.
• Insects will be attracted, resulting in insect damage.
• It also increases the formation of fungus and yeast, which can be harmful to one’s health.

How to Waterproof the Floor in a Laundry Room?

If the washing machine or its connections leak into the floor, water can run down into adjacent rooms on the same level. Leakage in your laundry room could lead to severe problems throughout your home.

When water from your washing machine or hoses escapes, it can seep into hardwood floors in adjacent rooms or even trickle down to the basement. To safeguard against these costly issues, implementing waterproofing measures in your laundry room is crucial.

Let’s look at some effective waterproofing methods to keep your laundry room dry and safe.

1. A membrane that keeps water out

A key solution to prevent water damage is the use of a waterproofing membrane. Unlike sheet-based products, these membranes are liquid-applied directly from a bucket and are designed to protect the subfloor. 

This method is ideal when laying a new floor over an existing one, such as tile over vinyl. Applying the membrane requires a notched trowel to evenly spread it across the floor surface, filling all cracks and edges for a comprehensive watertight barrier. 

Before you lay flooring on top of the membrane, it must be perfectly clean and dry. Once dried, this membrane forms a solid, moisture-resistant foundation for your new flooring.

I suggest using a material like Ditra as a transitional material from subfloor to tile. This approach, along with Kerdi band strips for seam sealing, can effectively waterproof the tile installation. 

Moreover, If you plan to use hardwood flooring in your laundry room, a waterproofing membrane can be particularly beneficial. While hardwood isn’t inherently resistant to water damage, the membrane can localize any potential water damage to the laundry room area itself, preventing it from affecting other rooms or seeping into ceilings below.

Now, if you’re considering whether to install a waterproof membrane on a sloped floor leading to a drain, a situation many homeowners face, you should be aware of some alternative options. Here they are:

2. Vinyl flooring

Vinyl flooring is a low-cost choice for waterproofing your floor. Available in a wide range of colors and patterns, it’s easy to find an option that matches your home’s decor. 

Vinyl sheets protect against water better than vinyl tile. However, if opting for tiles, ensure that every edge is sealed properly to maintain waterproof integrity. For added protection, consider extending the vinyl up the walls by a few inches and covering the edges with baseboard.

Should your vinyl flooring suffer any damage, such as dings or chips, sealing the area with caulk or replacing the damaged section is essential to retain its waterproof qualities.

Another option is LVF (luxury vinyl flooring). It is a slightly elevated vinyl that looks like real wood. Vinyl boards are available in a variety of colors and patterns, with the majority of them embossed and fashioned to look like real wood planks. When fitted correctly, they are watertight. To make sure that the job is done properly, get professional assistance with installation.

3. Ceramic Tiles

Ceramic tile, while more expensive than vinyl, offers enhanced durability and a range of design options. The grout between tiles, though porous and susceptible to staining when wet, doesn’t usually allow water to penetrate through to the subfloor. 

They are scratch-resistant but can be slippery. To ensure maximum waterproofing, treat the grout with a waterproof sealer, which may need reapplication over time.

To achieve a tight seal, you can also cement the tile’s outer edges where it touches the wall. Because the edges between ceramic tiles can become dirty rapidly, it is necessary to seal them.

4. Concrete Flooring

Consider using concrete in your laundry room if your house is built on a concrete slab. It is simple to clean and long-lasting. Contact a flooring professional for embossing, refinishing, or painting services if you’re dissatisfied with the appearance of your concrete laundry room floor.

5. The Importance of Caulk in Waterproofing

Regardless of the flooring type you choose, caulk is an indispensable tool in creating a waterproof barrier. Apply a generous amount of caulk along the edges of the flooring, whether it meets the wall or baseboard. 

PVC baseboards, which mimic the look of glossy painted or stained wood, can be a practical addition to rooms prone to moisture, like laundry rooms. They not only enhance the room’s aesthetics but also aid in containing any potential leaks.

Remember to seal around floor drains and pipe holes with a suitable silicone caulk or one specifically designed for bathroom use to ensure a fully waterproofed floor.

Waterproofing for Your Laundry Room: Is DIY a Good Idea?

Many homeowners consider DIY solutions to cut costs, but when it comes to waterproofing your laundry, it’s wise to think twice before taking matters into your own hands. Let’s explore why professional waterproofing is the safer choice and how DIY might end up being costlier in the long run.

Why Shouldn’t I Waterproof My Laundry Myself?

Precision and expertise are key in waterproofing. It’s not just about passing inspections if you plan to sell your home. With abundant information available online, many homeowners are tempted to undertake DIY projects. 

However, when it comes to waterproofing, the stakes are high. Incorrect or substandard waterproofing can lead to significant structural issues, including rot, mold, and even termite infestations. These problems can be much more expensive to fix than hiring a professional in the first place.

My advice is to entrust this task to professional waterproofing services, ensuring that you comply with standards and avoid potential damage.

Regulations and Standards in Waterproofing

It isn’t just a routine task. Waterproofing in buildings is a critical task governed by specific regulations and standards to ensure quality and safety. 

• The Australian Standard AS 3740-1994 and the Building Code of Australia (BCA) guide waterproofing in domestic areas like laundries and bathrooms in Australia, ensuring structural integrity and prevention of water damage. 
• In the United States, the International Building Code (IBC) and the International Residential Code (IRC) set the standards for waterproofing, focusing on building safety and performance, with particular attention to moisture-prone areas. 

This means that your laundry’s floors and walls require proper waterproofing techniques.

Choosing the Right Waterproofing Material

Not all waterproofing materials are created equal. Choices like Bituminous Membrane, Cementitious Membrane, or Liquid Membranes need to be matched with the specific requirements of your project. Our team of experts can help you select the appropriate materials and apply them correctly for long-lasting protection.

5 Key Tips to Prevent Water Damage in Your Laundry Room

Water damage is often associated with flooded basements and soaked carpets. However, to keep your laundry room safe and dry, follow these five essential tips:

1. Install Waterproof Flooring Mats: Protect your laundry room from water leakage from washing machines or dryers by placing waterproof flooring mats underneath these appliances. These mats are particularly useful if you have pets bringing in mud or dirt. They help contain messes and protect your sub-floor.
2. Regular Hose Maintenance: Ensure that hoses from your washing machine are emptied after each use, especially after washing bulky items. Avoid leaving hoses bent or kinked, as stagnant water in them can lead to mold and bacteria growth, and potentially attract pests.
3. Secure Your Washer and Dryer: For newer front-loading washers, check the door gaskets for any signs of leaks. Placing an extra rubber mat underneath can catch any accidental overspray. For older models, watch out for rust or wear and tear that might indicate leaks, and consider replacement if necessary. Similarly, for dryers, ensure the hoses are clear after each use and consider installing lint traps.
4. Immediate Water Cleanup: In case of any spillage, quickly mop or towel-dry the area. For damp items like boxes or papers, dry them completely before storing them away, using an air cycle in the dryer if needed to prevent mold growth.
5. Routine Maintenance Checks: Regularly inspect your appliances for leaks, ensure all connections are secure, and keep lint traps clean. Consult your washing machine’s manual for specific maintenance guidelines and consider professional inspections to preempt major issues.

How to Determine if Your Laundry Room is Waterproofed?

Determining whether a laundry room is waterproofed can be tricky without official documentation like a compliance certificate from the installer or homeowner. However, there are several indicators you can check for:

Ensuring that a laundry room is effectively waterproofed is crucial, especially when considering purchasing a property. Taking the time to perform these checks can save you from future hassles and expenses.

Conclusion

Toilets, showers, laundries, and bathrooms are all designated wet places in the home, so the materials used in these areas must be waterproof or resistant to water. Waterproofing laundry areas is a task that is sometimes omitted in new construction and home renovations to save money. You have spent huge amounts of money on your renovation. A few amounts spent on laundry waterproofing is a drop in the ocean compared.

It’s essential to hire a qualified professional for waterproofing applications. DIY or untrained installations can compromise the integrity of your home, leading to expensive renovations later. A professional installation ensures that the job is done right the first time.

When waterproofing isn’t done correctly or is neglected entirely, it can be a serious flaw in a home. At times, laundry can be as wet as, if not wetter than, a bathroom. Any wetness on the hardwood floor of a laundry area, whether tiled or not, invites deterioration. You must waterproof beneath your tiles, as per the standards.

Remember, the cost of proper waterproofing is minor compared to the expenses of fixing water damage. If you have further questions or need more advice on this topic, feel free to ask!

FAQs

Is a Waterproof Certificate Required?
