1.Facilities Specialized in Exterior Renovation
Kakeru Koumuten Co., Ltd. has prepared the following warehouses and material storage areas to provide exterior renovations such as waterproofing at lower costs and faster.
We have established 5 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.

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 savings on waste disposal can be achieved.

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
This time, since the customer wanted to renovate using a long-lasting method rather than just protective agents like topcoats, we proposed waterproofing work using a high-strength urethane ventilation buffer method.
Timing for Waterproofing Work
Already Experiencing Leaks
If leaks have already occurred, it is necessary to address them promptly before the damage spreads.
If left unattended, it can negatively affect the interior and the underlying structure, so it is essential to stop the leaks quickly.
Bloating or Cracking of the Waterproof Layer
If the waterproof section is cracked, it can cause rainwater to enter.
If the waterproof layer is bloated, it indicates that moisture is accumulating inside the waterproof 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 accumulated moisture or rainwater.
This can be caused by poor drainage or sinking of the waterproof layer due to aging.
Exceeding the Durability Years
Generally, the durability of 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 of the type of waterproofing, please send us a photo via email or LINE inquiry, and we will assess it!
Types of Waterproofing Work
1. Urethane Waterproofing
Urethane waterproofing is a method of applying liquid polyurethane resin onto 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 method is commonly used for large areas such as rooftops.
One advantage is that it does not require waiting for drying, making the installation faster compared to urethane waterproofing, 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.
Waterproofing Work | Learn about Rubber Sheet Waterproofing here!
3. PVC Sheet Waterproofing
PVC sheet waterproofing involves using waterproof sheets made of polyvinyl chloride, which, like rubber sheet waterproofing, adheres sheets to the surface to prevent water intrusion.
Similar to rubber sheets, it is not suitable for complex shapes. Although it is more expensive 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 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 sheet waterproofing, it may give 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 detailed information 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, with an overwhelmingly short construction period, often completed in just one day.
Due to its lightweight and cost-effectiveness, it seems that about 80% of single-family home balconies use FRP waterproofing.
However, it is not suitable for installation on large surface areas, making it less appropriate for rooftop applications.
For more detailed information 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 Asao-ku, Kawasaki.
Among the numerous contractors, I believe many people feel “I don’t know who to ask…”.
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 availability 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 the process 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 process.
To prevent troubles, it is important to hire an experienced and reliable contractor!
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 platforms like Instagram, so checking those can be effective!
It is also effective to refer to review sites to look for waterproofing construction companies!
A particularly recommended review site is “Google”, as contractors cannot arbitrarily delete low ratings, making it a trustworthy 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 for Aftercare and Construction Warranty
In case of any poor workmanship or defects after construction, make sure to confirm whether they provide a “construction warranty“!
Contractors who offer warranties are usually confident in their workmanship, making them more trustworthy!
If waterproofing work has been 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 construction!
Additionally, to detect any defects early, confirm whether they conduct thorough aftercare!
Since non-specialized contractors may not notice signs of defects or troubles, having a specialized contractor perform regular aftercare can help prevent issues before they arise!
Our company sends out aftercare DM every year, so if desired, annual aftercare can be arranged!
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 and warranties or after-services may vary between contractors.
Moreover, 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,” and compare the details!
Confirm Whether They Perform Waterproofing Work In-House
Check whether they perform waterproofing construction in-house!
If a sales company investigates and then requests a subcontractor, it will incur additional time and costs.
Also, there may be cases where customer requests are not fully communicated to subcontractors, leading to troubles. By having one company handle everything from sales to construction, responsible waterproofing work can be performed quickly and cost-effectively. Kakeru Koumuten conducts 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 use the optimal method and materials based on the construction site 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 substrate?” and “are the materials appropriate?”
Thus, if the materials used are only “urethane waterproofing materials,” make sure to confirm the product name and understand what kind of materials they are!
