| 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.
・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 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 trouble 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
If 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 area 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 accumulated 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.
Before curing, it is in liquid form, allowing it to 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.
For more detailed information about the advantages and disadvantages of PVC sheet waterproofing and maintenance methods, please refer to the article below.

4. Long Sheet Waterproofing
Long sheet waterproofing, officially known as “anti-slip vinyl flooring sheet,” is commonly applied in shared areas of apartments and on stairs 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 rooftops of apartments where people do not frequently enter.
For more detailed information about the advantages and disadvantages of long sheet waterproofing and maintenance methods, 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 on single-family home balconies, and the construction period is significantly short, often completed in as little as 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 installation on large areas, making it less appropriate for rooftops.
For more detailed information about the advantages and disadvantages of FRP waterproofing and maintenance methods, 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 for 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 Minamiashigara City.
Among the numerous contractors, I believe there are many who feel, “I don’t know who to ask…”.
Choosing the right contractor can be challenging at first, 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 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 construction defects during the installation.
To prevent troubles, it is important to hire a contractor that is experienced and trustworthy!
You need to refer to the contractor’s website for their past work 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, 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 verification!
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 ensure early detection of any issues that may arise, confirm if they provide thorough aftercare maintenance!
Since non-specialized contractors may not notice signs of problems or troubles, having a specialized contractor conduct 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 three)
When requesting waterproofing work, be sure to obtain estimates from multiple contractors.
We recommend obtaining estimates from at least three companies.
The costs may vary between contractors even for the same waterproofing work, and the warranties and after-services may differ as well.
Additionally, obtaining multiple estimates makes price negotiations easier. To request at the lowest possible price, it is essential to get estimates from several contractors.
When comparing estimates, be sure to check not only the costs but also the “types of materials used” and “construction methods” for detailed comparisons!
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 additional time and costs.
Moreover, there may be cases where customer 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!
Furthermore, if any leaks or troubles occur, 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 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 like “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!
