Reasons why Kakeru Koumuten is chosen for waterproofing work in Atsugi City
The reasons why our company can be entrusted with waterproofing work by customers in Atsugi City include
one reason being that we have a base in Kanagawa Prefecture, but
“Our strengths in waterproofing work that cannot be imitated by other companies”
which has received high praise from many customers.
we have absolute confidence in “cost,” “quality,” and “plans,” so
we would appreciate it if you could compare our estimates with those of other companies.
Because we are confident, we welcome competitive estimates!
1．Specialized equipment for exterior renovations
At Kakeru Koumuten Co., Ltd., we have organized the following warehouses and material storage areas to provide more affordable and faster exterior renovations such as waterproofing work.
We have established five bases centered around Aoba-ku, Yokohama for material storage and showrooms.
In-house Ownership of Scaffolding Materials
We own the scaffolding materials necessary for temporary scaffolding required for waterproofing work, allowing us to assemble temporary scaffolding in-house.
By not outsourcing scaffolding work and using our own scaffolding team, we can also cut costs associated with scaffolding construction.
Since everything is done in-house, we can significantly reduce costs through shortened construction periods!
We have approximately enough scaffolding materials for 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 canprocure materials at a lower cost!
Additionally, we always have waterproofing components in stock, allowing us torespond quickly to emergency waterproofing work!
Separation of waste materials in-house
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 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 complete in-house construction.
From inquiry to project completion, everything is handled by Kakeru Koumuten Co., Ltd. This allows 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.

We have obtained permits for construction work and industrial waste collection and transportation!
We also have qualified personnel on staff, and we 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!

| Inquiry Details |
| We received the following inquiries from our customer: ・There are wrinkles and bulges in the waterproof sheet on the rooftop, so I am worried about leaks. ・I would like 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. |
Our Proposal
Since you mentioned wanting a long-lasting method rather than just protective agents like top coats, we proposed a complete “urethane waterproofing project” for the rooftop.
If urethane waterproofing is applied using the 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 tube.”
This can prevent the most common issue in 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
If Leaks Have Already Occurred
If leaks have already occurred, it is necessary to address them promptly before the damage spreads.
If left unattended, it can adversely affect the interior and underlying structures, so it is essential to stop the leaks quickly.
Bulging or Cracking of 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.
Bulging can lead to cracks, which can result in leaks, so early detection and action are necessary.
Growth of Moss or Mold
Moss or mold can develop due to the accumulation of moisture or rainwater.
This can be caused by poor drainage or sinking of the waterproof layer due to aging.
If the Durability Period Has Been Exceeded
Generally, the durability period for waterproofing work is 10 to 20 years.
Of course, the durability period can vary depending on the construction method and materials, but for some types of waterproofing, it is recommended to apply only the 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.
Since it is liquid before curing, it can be applied to complex shapes, and unlike sheet waterproofing, it can be installed 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.

3. PVC Sheet Waterproofing
PVC sheet waterproofing is a waterproof sheet made of polyvinyl chloride, which, like rubber sheet waterproofing, is applied 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 long durability is a significant advantage.
We provide detailed explanations about the advantages, disadvantages, and maintenance methods of PVC sheet waterproofing in the article below.

4. Long Sheet Waterproofing
Long sheet waterproofing, officially known as “anti-slip vinyl floor sheet,” is commonly applied in shared areas and stairs 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 the rooftops of apartments where people do not frequently enter and exit.
We provide detailed explanations about the advantages, disadvantages, and maintenance methods of long sheet waterproofing 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 applied 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 use FRP waterproofing.
However, it is not suitable for areas with complex shapes, making it less appropriate for rooftop applications.
We provide detailed explanations about the advantages, disadvantages, and maintenance methods of FRP waterproofing 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 waterproofing is used in large buildings 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 detailed information 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 Atsugi City.
Among the numerous contractors, there are likely many who feel, “I don’t know who to ask for help…”.
Choosing the right contractor can be challenging at first, so I will explain 5 points to be careful about when requesting waterproofing work.
● Have extensive experience in waterproofing work
● Confirm the presence of aftercare and warranty
● Obtain estimates from multiple contractors (at least 3 companies)
● Check if they perform 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 poor construction during the installation.
It is important to hire an experienced and trustworthy contractor to prevent troubles!
You need to refer to the contractor’s website for their construction achievements and reviews to make a judgment.
There are also contractors who showcase their achievements on social media like Instagram, so checking those can be effective!
It is also effective to look at waterproofing companies on review sites for reference!
The review site we particularly recommend is “Google”.
Since contractors cannot delete low ratings on their own, it is a reliable source of 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 is done, let’s confirm if they provide a “construction warranty”!
Contractors who offer warranties are usually confident in their work, making them more trustworthy!
If waterproofing work is done, make sure to have photos taken of 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 it will facilitate smooth communication shortly after the work is completed!
Also, to detect any issues early, confirm whether they will conduct thorough aftercare maintenance!
If a contractor is not specialized, they may miss signs of problems or troubles, so having a specialized contractor perform regular aftercare maintenance can prevent issues before they arise!
Our company sends out aftercare maintenance DM every year, so if desired, annual aftercare maintenance is possible!
Obtain estimates from multiple contractors (at least three)
When requesting waterproofing work, always get estimates from multiple contractors.
We recommend obtaining estimates from at least three companies.
Even for the same waterproofing work, costs and warranties or after-service may vary between contractors.
Additionally, obtaining multiple estimates makes it easier to negotiate prices. To request at the lowest possible cost, it is essential to get estimates from several contractors.
When comparing estimates, check not only the costs but also the details such as “types of materials used” and “construction methods”!
Confirm if they perform waterproofing work in-house
Check if they perform waterproofing work in-house!
If a sales company investigates and then requests a subcontractor, it will take more time and cost.
Moreover, there may be cases where your requests are not fully communicated to the subcontractor, leading to troubles.
By having one company handle everything from sales to construction, responsible waterproofing work can be done quickly and cost-effectively. Kakeru Koumuten conducts everything from on-site surveys to actual construction in-house!
Also, in the event of rain leaks or troubles, if the company has its own craftsmen, they 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 “methods,” “materials,” and “processes,” 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, including “high-strength specifications,” “heat-insulating specifications,” and “anti-slip specifications.” Therefore, it is essential to confirm whether the construction content is appropriate for the installation location!
It is important not to judge solely based on cost, but to carefully check whether “the method is appropriate for the base material?” 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!
