| Inquiry Details |
| We 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. ・We would like an estimate for a complete waterproof renovation, not just partial repairs or a top coat. ・We learned that urethane waterproofing has high waterproofing properties, so we would like an estimate for urethane waterproofing. ・Since this is our first waterproofing project, we would like to compare estimates. |
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 applying urethane waterproofing.
By applying the ventilation buffer sheet first, the air rising from the building is controlled by the ventilation sheet and expelled through a “ventilation pipe.”
This can prevent the most common problem 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
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.
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 and subsequently to leaks, so early detection and action are necessary.
Moss or Mold Growth
Moisture and rainwater accumulation can lead to the growth of moss or mold.
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 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 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 that involves applying liquid polyurethane resin to the waterproofing surface in layers.
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 for 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.
Similar to 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.
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 “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 capability.
It is rarely used in areas like the rooftops of apartments where people do not frequently enter.
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 used in single-family home balconies, and the construction period is remarkably short, often completed in just one day.
Due to its lightweight and low cost, it is estimated that about 80% of single-family home balconies use FRP waterproofing.
However, it is not suitable for construction on large surface areas, making it less appropriate for rooftop applications.
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 secured with cinder concrete.
This 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 benefit 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 Machida City, Tokyo.
Among the numerous contractors, I believe many people 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 keep in mind 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 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 an experienced and reliable 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 companies on review sites for reference!
A particularly recommended review site is “Google”.
Since contractors cannot delete low ratings on their own, it provides trustworthy 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 a warranty are usually confident in their work, making them more trustworthy!
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 it will facilitate smooth communication shortly after the work is completed!
Additionally, to ensure early detection of any issues that may arise, check if they provide thorough aftercare maintenance!
Since non-specialized contractors may not notice signs of trouble, having a specialized contractor conduct regular aftercare maintenance can help prevent issues before they occur!
Our company sends out aftercare maintenance DMs every year, so if you wish, annual aftercare maintenance is possible!
Obtain estimates from multiple contractors (at least three)
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, 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 work 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 your requests are not communicated 100% to the subcontractor, leading to troubles.
By having one company handle everything from sales to construction, responsible waterproofing work can be carried out quickly and cost-effectively. Kakeru Koumuten conducts everything from on-site surveys to actual construction in-house!
Furthermore, 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 “methods,” “materials,” and “processes,” and it is necessary to carry out the work using the most suitable method and materials depending on the construction site and existing substrate.
For example, even with the same urethane waterproofing, there are different 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 details are 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!
