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 more affordably and more quickly.
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 all work is performed in-house, it is possible to 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 can be achieved.

In the unlikely event that leaks are not resolved after the waterproofing work, we will take responsibility and address the issue!
Additionally, aftercare maintenance is available every year, and we will send you a DM notification for aftercare maintenance once a year. During aftercare maintenance, we will check the entire waterproofing and assess the deterioration status.

If you cannot 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 could cause problems, so our company maintains a system where the representative remains the same.

Examples of Waterproofing Work
工事内容
Rooftop urethane waterproofing work (ventilated buffer method)
Ventilation sheet: QV sheet
We received an inquiry from a customer living in Shibuya-ku, Tokyo, stating, “I am concerned about the deterioration of my rooftop, so I am considering waterproofing work. I would like to request a quote first.”
Our Proposal
Since the customer expressed a desire to renovate using a long-lasting method, not just protective agents like topcoats, we proposed waterproofing work using a ventilation buffer method with high-strength urethane.
Timing for Waterproofing Work
Already Experiencing Leaks
If leaks have already occurred, it is necessary to address the issue 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.
Bloating or Cracking of the Waterproof Layer
If the waterproof section is cracked, it can lead to rainwater intrusion.
If the waterproof layer is bloated, it indicates that moisture is accumulating inside the layer.
Bloating 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 the accumulation of 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 between 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 only the surface protective agent (topcoat) approximately every 8 years (such as urethane waterproofing or FRP waterproofing).
We recommend regular inspections starting from 5 years after construction.
It is important to understand the type of existing waterproofing and perform appropriate maintenance.
If you are unsure about the type of waterproofing, please send us a photo via email or LINE inquiry, and we will help you determine it!
Types of Waterproofing Work
1. Urethane Waterproofing
Urethane waterproofing is a type of waterproofing that involves applying liquid polyurethane resin to the waterproofing surface.
Before curing, it is in liquid form, allowing it to be applied even on complex shapes, and unlike sheet waterproofing, it can be installed without seams.
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 consists of waterproof sheets made from polyvinyl chloride, which, like rubber sheet waterproofing, is adhered to the surface to prevent water intrusion.
Similar to rubber sheets, it is not suitable for application on complex shapes. While the cost is higher than rubber sheets and urethane waterproofing, its durability is a significant advantage.
For more details on the advantages, disadvantages, and maintenance methods of PVC sheet waterproofing, please refer to the article below.

4. Long Sheet Waterproofing
Long sheet waterproofing, officially known as “slip-resistant vinyl floor sheet,” is a waterproofing method commonly applied in areas where people walk, such as shared spaces and staircases in condominiums.
As the name suggests, it is slip-resistant and has high durability and wear 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 sheet waterproofing, it may have a slightly lower impression of waterproofing performance.
It is rarely used in areas like the rooftops of condominiums where people do not frequently enter and exit.
For more details on the advantages, disadvantages, and maintenance methods of long sheet waterproofing, please refer to 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, and the construction period is overwhelmingly short, often completed in as little as one day.
Due to its lightweight and cost-effectiveness, it seems that about 80% of single-family home balconies utilize FRP waterproofing.
However, it is not suitable for installation on large surface areas, making it less appropriate for rooftops.
For more details on the advantages, disadvantages, and maintenance methods of FRP waterproofing, please refer to the article below.

6. Asphalt Waterproofing
Asphalt waterproofing refers to 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 Tama-ku, Kawasaki.
Among the numerous contractors, I believe there are many who feel “I don’t know who to ask…”.
Choosing a contractor for the first time can be challenging, so I will explain 5 points to consider when requesting waterproofing work.
● Have extensive experience in waterproofing work
● Check for aftercare maintenance and warranty availability
● Obtain estimates from multiple contractors (at least 3 companies)
● Confirm whether they perform waterproofing work in-house
● Carefully check 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 construction troubles are caused by poor workmanship during the construction.
To prevent troubles, it is important to hire an experienced and trustworthy contractor!
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 construction companies based on review sites!
A particularly recommended review site is “Google”, as contractors cannot arbitrarily delete low ratings, making it 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 arise after the work is completed, make sure to check if they provide a “construction warranty“!
Contractors who offer a warranty are usually confident in their work, making them more trustworthy!
If waterproofing work is done, make sure to have photos taken of the unseen areas during the process for confirmation!
Check for leaks during rainy weather after the waterproofing work, and if anything arises, contact the contractor immediately as it will facilitate smooth communication shortly after the construction!
Additionally, to detect any issues early, confirm whether they will conduct thorough aftercare maintenance!
Since non-specialized contractors may not notice signs of problems or troubles, having a specialized contractor perform regular aftercare maintenance can help 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 3)
When requesting waterproofing work, be sure to obtain estimates from multiple contractors. We recommend obtaining estimates from at least 3 companies.
Even for the same waterproofing work, costs may vary between contractors, and warranties and after-services may differ as well.
Furthermore, obtaining multiple estimates makes it easier to negotiate prices. To request at the lowest possible cost, obtaining estimates from several contractors is essential. When comparing estimates, be sure to check not only the costs but also the “types of materials used” and “construction methods” to compare the finer details!
Check if they perform waterproofing work in-house
Confirm whether they perform waterproofing construction in-house!
If a sales company investigates and then requests a subcontractor, it will take more time and money.
Also, there may be cases where the customer’s 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 handles everything from on-site surveys to actual construction in-house!
In the unlikely event that a leak or trouble occurs, a company that employs its own craftsmen can respond to and resolve issues quickly!
Carefully check the details, processes, and materials used in waterproofing estimates
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 based 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 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?”
Thus, if the materials used are only “urethane waterproofing materials,” let’s confirm the product name and check what kind of materials they are!
