Reasons why Kakeru Koumuten is chosen for waterproofing work in Ebina City
Regarding the reasons why our company is entrusted with waterproofing work by customers in Ebina City,
one reason is that we have a base in Kanagawa Prefecture, but
“Our strengths in waterproofing work that cannot be imitated by other companies”
have received high praise from many customers.
“Cost,” “Quality,” “Plan” are our absolute strengths, so
we would be grateful if you could compare us with estimates from other companies.
Because we are confident, we welcome competitive estimates!
1.Facilities Specialized in Exterior Renovation
Kakeru Koumuten Co., Ltd. has organized the following warehouses and material storage areas to provide exterior renovations such as waterproofing at lower costs and faster speeds.
We have established five bases centered around Aoba-ku, Yokohama for material storage and showrooms.
In-House Scaffolding Materials
We own the scaffolding materials necessary for temporary scaffolding required for waterproofing work, allowing us to assemble temporary scaffolding in-house.
By conducting scaffolding work with our own scaffolding team instead of outsourcing, we can also reduce the costs associated with scaffolding work.
Since everything is handled in-house, we can significantly reduce costs by shortening the construction period!
We have enough scaffolding materials for approximately 50 single-family homes!
Storage of materials in our large in-house warehouse
We store roofing materials and waterproofing components.
By ordering a large quantity of materials at once, we can purchase materials at a lower cost!
Additionally, we always have waterproofing components in stock, allowing us to respond quickly to emergency waterproofing work!
In-house sorting of waste materials
In waterproofing work, various waste materials are generated.
Most contractors dispose of them all together, but by sorting and recycling waste materials, significant cost reductions in waste disposal fees can be achieved.
Exterior Renovation Dedicated Showroom
In our showroom, not only can you have meetings, but you can also
directly check the actual structure and colors.
2．Complete In-House Construction
One of Kakeru Koumuten’s major strengths is its complete in-house construction.
From inquiry to project completion, everything is handled by Kakeru Koumuten Co., Ltd., allowing us to keep costs down while providing high-quality waterproofing work.
Additionally, one representative will assist you from the estimate to the completion of the work.
Since the same person will handle sales and construction management, smooth communication is possible.
We are confident in our construction plans and costs, so we welcome competitive estimates!
3. Various Permits and Skilled Workers
We have obtained construction industry permits and permits for industrial waste collection and transportation!
We also have qualified personnel on staff and are confident in our construction techniques.
We are capable of handling large-scale waterproofing projects, such as those for factories!
4. Warranty and Aftercare
Waterproofing work comes with a guarantee!
Depending on the type of waterproofing work, we provide a 5 to 10-year leak guarantee.
If you have any questions about the guarantee, please click on the image above!
In the unlikely event that leaks are not resolved after the waterproofing work, we will take full responsibility and respond accordingly!
Additionally, aftercare maintenance is available every year, and we will send you a DM reminder for aftercare maintenance each year.
During aftercare maintenance, we will check the entire waterproofing system and assess the condition of any deterioration.
5. Flexible and Prompt Response
Our company is equipped to handle various troubles and situations.
If you are unable to access the rooftop for waterproofing checks, we will utilize drones to assess the condition.
During leak investigations, we can also conduct inspections using thermal imaging cameras.
We will respond according to your wishes.
We also accept emergency measures for sudden leaks!
Since our sales and construction management are not separated, one dedicated representative will handle everything from the estimate to the completion of the work!
Changing representatives frequently can lead to miscommunication regarding the details and precautions of the work, which may cause issues, so we maintain a system where the representative remains the same.
6. Human Resource Development
We are creating various building models to enhance our skills and conducting practical training.
To ensure that each staff member can handle various buildings, we regularly provide technical training.

| Inquiry Details |
| We have received the following inquiries from our customer. ・There are wrinkles and bulges in the waterproof sheet on the rooftop, so we are worried about leaks. ・Please provide an estimate for a complete waterproof renovation, not just partial repairs or a top coat. ・I learned that urethane waterproofing has high waterproofing properties, so I would like an estimate for urethane waterproofing. ・Since this is my first waterproofing project, I would like to compare estimates from multiple companies. |
Our Proposal
Since you expressed a desire to renovate using a long-lasting method rather than protective agents like top coats, we proposed a complete “urethane waterproofing project” for the rooftop.
If urethane waterproofing is applied using a direct adhesion method, air rising from the building can cause bulges in the waterproof layer, so we proposed the “urethane waterproofing ventilation buffer method.”
The ventilation buffer method involves applying a ventilation buffer sheet over the entire area before installing the urethane waterproofing.
By applying the ventilation buffer sheet first, the air rising from the building is suppressed by the ventilation sheet and expelled through the “ventilation pipe.”
This method can prevent the most common issue with waterproofing, which is bulging of the waterproof layer!
After explaining the materials and methods, you entrusted the work to us among the four estimates you received!
Timing for Waterproofing Work
Leaks Have Already Occurred
If leaks have already occurred, it is necessary to address the issue promptly before the damage spreads.
If left unattended, it can negatively affect the interior and underlying structures, so it is essential to stop the leaks quickly.
Bulges or Cracks in the Waterproof Layer
If the waterproof section is cracked, it can lead to rainwater intrusion.
If the waterproof layer is bulging, it indicates that moisture is accumulating within the layer.
Bulges can lead to cracks, which can result in leaks, so early detection and action are necessary.
Moss or Mold Growth
Moss or mold can develop due to accumulated moisture or rainwater.
This can be caused by poor drainage or sinking of the waterproof layer due to aging.
Exceeding the Durability Period
Generally, the durability period for waterproofing work is 10 to 20 years.
Of course, the durability can vary depending on the construction method and materials, but for some types of waterproofing, it is recommended to apply a surface protective agent (top coat) approximately every 8 years (such as urethane waterproofing or FRP waterproofing).
We recommend conducting regular inspections starting from 5 years after construction.
Understanding the types of waterproofing and performing appropriate maintenance is essential.
If you are unsure about the type of waterproofing, please send us a photo via email or LINE, and we will help you determine it!
Types of Waterproofing Work
1. Urethane Waterproofing
Urethane waterproofing is a method where liquid polyurethane resin is applied in layers to the waterproofing surface.
Before curing, it is in liquid form, allowing it to be applied to complex shapes, and unlike sheet waterproofing, it can be applied without seams, which is a significant advantage.
It can be widely applied to balconies, rooftops, and more.
For more details on the advantages, disadvantages, and maintenance methods of urethane waterproofing, please refer to the article below.

2. Rubber Sheet Waterproofing
Rubber sheet waterproofing involves adhering synthetic rubber sheets to the surface to prevent water intrusion.
This type of waterproofing is commonly used on large areas such as rooftops.
Compared to urethane waterproofing, it has the advantage of faster installation since there is no waiting for drying, but it is not suitable for complex surfaces.
For more details on the advantages, disadvantages, and maintenance methods of rubber sheet waterproofing, please refer to the article below.
For more on waterproofing work | Rubber sheet waterproofing, click here!
3. PVC Sheet Waterproofing
PVC sheet waterproofing is a waterproof sheet made of polyvinyl chloride, which, like rubber sheet waterproofing, is adhered to the surface to prevent water intrusion.
Like rubber sheets, it is not suitable for complex shapes. Although the cost is higher than rubber sheets and urethane waterproofing, its durability is a significant advantage.
We provide detailed explanations about the advantages and disadvantages of PVC sheet waterproofing, as well as maintenance methods, in the article below.

4. Long Sheet Waterproofing
Long sheet waterproofing, officially known as “anti-slip vinyl floor sheet,” is commonly used in shared areas and staircases of apartments where people walk.
As the name suggests, it is slip-resistant and has high durability and abrasion resistance, making it suitable for walking areas.
Additionally, it comes in various designs, excelling in aesthetic appeal.
However, it tends to be more expensive, and since it does not overlap seams like rubber sheets or PVC sheets, it may give a slightly lower impression of waterproofing performance.
It is rarely used in areas like rooftops of apartments where people do not frequently enter.
We provide detailed explanations about the advantages and disadvantages of long sheet waterproofing, as well as maintenance methods, in the article below.

5. FRP Waterproofing
FRP waterproofing involves creating a waterproof layer by solidifying glass mat with epoxy resin to prevent rainwater intrusion.
It is commonly used in single-family home balconies, with an overwhelmingly short construction period, often completed in as little as one day.
Due to its lightweight and low cost, it seems that about 80% of single-family home balconies utilize FRP waterproofing.
However, it is not suitable for construction on large surface areas, making it less appropriate for rooftops.
We provide detailed explanations about the advantages and disadvantages of FRP waterproofing, as well as maintenance methods, in the article below.

6. Asphalt Waterproofing
Asphalt waterproofing is a waterproof sheet that has asphalt permeated into synthetic fiber non-woven fabric.
The waterproofing shown in the photo is a method where asphalt waterproofing is pressed down with cinder concrete.
This type of waterproofing is used in buildings with large areas, such as rooftops of schools and commercial facilities.
There are various methods of asphalt waterproofing, each with its own advantages and disadvantages, but a significant advantage is its high durability.
For more details on the advantages, disadvantages, and maintenance methods of asphalt waterproofing, please refer to the article below.

How to Choose a Waterproofing Contractor
There are many waterproofing contractors available in Ebina City.
Among the numerous contractors, there are likely many who feel, “I don’t know who to ask for help…”
Choosing a contractor for the first time can be challenging, so here are 5 points to keep in mind when requesting waterproofing work.
● Have extensive experience in waterproofing work
● Confirm the availability of aftercare and warranties
● Obtain estimates from multiple contractors (at least 3 companies)
● Check if the contractor performs waterproofing work in-house
● Carefully review the details of the waterproofing estimate, including processes and materials used
By confirming the above 5 points, you will be able to choose a reliable contractor.
Check if they have extensive experience in waterproofing work
About 10-20% of waterproofing work troubles are caused by construction defects during the installation.
To prevent troubles, it is important to hire a contractor who is experienced and trustworthy!
You need to refer to the contractor’s website for their construction achievements and reviews to make a judgment.
Some contractors showcase their achievements on social media platforms like Instagram, so checking those can also be effective!
It is also effective to look at waterproofing companies on review sites for reference!
A particularly recommended review site is “Google”.
Since contractors cannot delete low ratings on their own, it provides reliable reviews.
If there are many negative reviews or no reviews at all, it may be wise to refrain from making a request.
Check if there is aftercare maintenance and construction warranty
In case any construction defects or issues occur after the work, let’s confirm if they provide a “construction warranty”!
Contractors who offer a warranty tend to have confidence in their work, making them more trustworthy companies!
If waterproofing work is done, make sure to take photos of the hidden areas during the process for confirmation!
Check for leaks during rainy weather after the waterproofing work, and if there are any issues, contact the contractor immediately, as communication will be smoother shortly after the work is completed!
Additionally, to ensure early detection of any problems that may arise, confirm whether they conduct thorough aftercare maintenance!
Since non-specialized contractors may not notice early signs of issues or troubles, having a specialized contractor perform regular aftercare maintenance can prevent troubles before they occur!
Our company sends out aftercare maintenance DM every year, so if desired, annual aftercare maintenance is possible!
Obtain estimates from multiple contractors for waterproofing work (at least three companies)
When requesting waterproofing work, be sure to obtain estimates from multiple contractors.
We recommend obtaining estimates from at least three companies.
Even for the same waterproofing work, costs may vary between contractors, and warranties and after-services may differ as well.
Moreover, obtaining multiple estimates makes it easier to negotiate prices. To request at the lowest possible cost, obtaining estimates from multiple contractors is essential.
When comparing estimates, make sure to check not only the costs but also the details such as “types of materials used” and “construction methods”!
Check if they perform waterproofing work in-house
Confirm whether they carry out waterproofing work in-house!
If a sales company investigates and then requests a subcontractor, it will incur extra time and costs.
Also, there may be cases where customer requests are not 100% communicated to the subcontractor, leading to troubles.
By having one company handle everything from sales to construction, it enables responsible waterproofing work that is quick and cost-effective. Kakeru Koumuten conducts everything from on-site surveys to actual construction in-house!
Additionally, in the unlikely event of leaks or troubles, a company that employs its own craftsmen can respond to and resolve issues quickly!
Carefully Check the Details of the Waterproofing Estimate, Process, and Materials
Even for the same waterproofing work, there are various types such as “method,” “materials,” and “process,” and it is necessary to carry out the work using the most suitable method and materials depending on the construction location and existing substrate.
For example, even with the same urethane waterproofing, there are different types of processes such as “adhesion method” and “ventilated buffer method,” and there are various types of urethane waterproofing materials such as “high-strength specification,” “heat-insulating specification,” and “anti-slip specification.” Therefore, it is essential to confirm whether the construction content is appropriate for the location!
It is important not to judge solely based on cost, but to carefully check whether “the method is appropriate for the substrate?” and “are the materials suitable?”
So, if the materials used are only “urethane waterproofing materials,” let’s confirm the product name and check what kind of materials they are!
