Leaky walls and surprise puddles are no fun. Rainwater belongs outside, not in your living room.
Getting waterproofing in Bali ensures your home stays dry and protected all year round. You don’t have to worry every time clouds roll in. It’s a small step that can save you big headaches later because dry walls make for a happier home.
And to help you out, we’ve rounded up some of the most reliable waterproofing companies so you can choose what best suits your home.
How much do waterproofing services cost in Bali?
Waterproofing services in Bali typically cost between IDR 45,000 and IDR 75,000 per square meter, depending on the method and materials used. Some companies offer warranties and site inspection packages, especially for villa or resort-scale jobs.
1. RBP Waterproofing
Address: Jl. Singasari Utara No.61, Peguyangan, Kec. Denpasar Utara
Contact Details: +6285735415998
Business Hours:
- Monday to Friday: 8 AM – 5:30 PM
- Saturday: 9 AM – 5:30 PM
We found RBP Waterproofing to be one of the more tech-forward firms in Denpasar. They operate as a regional branch of a national company with over 15 years of experience.
One thing that stood out was their use of heavy-duty materials, such as spray polyurea coatings, up to 1000 microns thick. They also offer “membran bakar” torch-on systems, which are done with proper heat-sealing equipment.
Their moisture inspections are surprisingly advanced. They come with sensors and meters to provide a quote.
We even obtained the breakdown by surface type and system, and we started at IDR 55,000 per square meter for basic work.
They even offer epoxy flooring and hardeners for people wanting functional and good-looking waterproofing. We also liked that they offer optional maintenance contracts and post-job inspections, very rare at this price level.
On the flip side, they are not purely specialists in leak diagnostics. Their broad service menu includes coating and flooring. If you’re looking for a forensic-type leak tracker, you might want someone who focuses strictly on that area.
Price was competitive, and the quality was excellent
“Very satisfied with Mr. Abdul’s torch-on membrane installation service. His team was professional, neat, and the results were very satisfying. The work was done quickly. The price was competitive, the quality was excellent, and the roof leaks were significantly reduced. Highly recommended!”

Quick, kind, polite, and responded very quickly
“The team was all quick, kind and polite, and responded very quickly even though it was a holiday, one day of the survey, then the next day it was completed in a day. Hopefully it lasts as promised. Keep up the good work! 🙏🏼 …”

2. Amanah Mandiri Bali
Address: Gg. Carik I No.118, Pemecutan, Kec. Denpasar Bar., Kota Denpasar
Contact Details: +6281246514369
Business Hours:
- Open 24 Hours
Amanah Mandiri Bali’s deep experience in villa-scale waterproofing, epoxy floors, and general repair jobs across Denpasar, Ubud, and even Lombok caught our attention.
Their scope covers torch-on membranes, cementitious sealants, and PU injections for everything from rooftops to bathrooms.
They quoted us IDR 65,000 per m², which was fair considering their various methods—torch-on and elastomeric coating. The team was equipped with trained applicators and showed a good technical range, not just basic waterproofing.
One heads-up, though: while they say warranties are included, we didn’t get a written one for our small residential job. It’s not a total deal-breaker, but we would suggest asking for something in writing if that’s important to you.
Still, their no-cost site survey made up for it. It included moisture checks and drainage suggestions that most others skipped. That extra diagnostics layer made their recommendation feel less salesy and more engineered.
On top of that, they patched a hard-to-reach planter box with fibre coating and didn’t charge extra. It was a small job, but how they handled it made us feel like our project mattered.
The team was very responsive and professional
“I am very satisfied with the results of Amanah Mandiri Bali’s work for waterproofing services in my house. From the beginning of communication, their team was very responsive and professional. They came on time for the site survey, explained in detail the cause of the leak, and provided the best solution that suits the condition of the building.”

I highly recommend Amanah Mandiri Bali for your waterproofing needs, because they provide the best service with perfect results.”

3. Injeksi Beton Dan Waterproofing
Address: 952V+4RV, Gg. Munduk Indah, Pemecutan Kaja, Kec. Denpasar Utara, Kota Denpasar
Contact Details: +6289510006747
Business Hours:
- Monday to Sunday: 8 AM – 5 PM
This Denpasar-based crew focuses solely on leak repair and waterproofing, particularly through concrete injection methods like high-pressure polyurethane and cement admixture systems.
They are not a one-size-fits-all contractor, and that’s clear from their three specialised injection types: PU, water-plug cement, and a cement-admixture mix, all tailored for different crack conditions.
What sold us was their clean execution. They drilled only tiny ports to inject from the inside, so the tiles and surrounding surface were completely untouched.
Beyond the injections, they also do membrane waterproofing, integral admixture systems, epoxy floor finishes, and even grouting.
Their 5-year warranty is also reassuring, especially knowing their methods target the root of the leak and not just the surface.
We also like that they seal leaks and prevent future ones through internal structural reinforcement. Their PU injection expands inside cracks and restores the concrete’s integrity, which not many Bali providers offer at this level.
One downside is how outdated and limited their website is. Without messaging them directly on WhatsApp, we couldn’t find any case studies or before-and-after images.
Workmanship is thorough and neat

4. Qiyyama Aretha Solution
Address: Jl. Imam Bonjol No.51, Pemecutan, Kec. Denpasar Bar., Kota Denpasar
Contact Details: +6281233332643
Business Hours:
- Monday to Saturday: 9 AM – 5 PM
Qiyyama Aretha Solution handles concrete injection, floor hardeners, and membrane coatings, so it was easy to manage overlapping work in one go.
Our concern involved applying a torch-applied bitumen membrane and silicone sealant, priced at approximately IDR 72,000 per m². This already included scaffolding and post-job cleanup.
We also appreciated that they offered a free survey visit beforehand and didn’t rush the consultation. They even ran moisture tests on the slab before quoting.
One thing to watch for is that the quality of service delivery may vary depending on your location. They operate across Bali, but if you’re outside Denpasar or Badung, it’s best to ask for project photos or referrals before locking anything in.
Still, what stood out for us was the aftercare. They promised a 6-month follow-up inspection and minor patch-up, which not many Bali providers do without extra fees.
We were also impressed by how they approach deep repairs, using surface sealing and structural strengthening with PU and epoxy injections.
Very neat, and done by professional people
“The installation was very neat, and done by professional people, and the price was also very friendly and what’s more important is that the owner is super friendly.”

5. Gurtex Waterproofing
Address: Jl. Bypass Ngurah Rai No.22, Kedonganan, Kec. Kuta, Kabupaten Badung
Contact Details: +628118689060
Business Hours:
- Monday to Friday: 8 AM – 5 PM
- Saturday: 9 AM – 12 PM
Gurtex Waterproofing specializes in water-based, anti-corrosion coatings specifically designed for tropical and coastal conditions.
Their SG368 liquid latex sealant provided us with both waterproofing and rust protection in one pass, while the SG168 roof coating helped reduce surface temperatures by 10°C.
At IDR 95,000 per square meter, our job included materials and labor, with no additional charges later.
They’re based in Kedonganan but cater to developers and contractors island-wide. We are amazed that their coatings work on metal, bamboo, concrete, and even decorative finishes like exposed cement.
We also loved that everything was non-toxic, water-based, and safe to apply on damp surfaces.
However, they don’t offer membrane-only or injection repair systems. If your issue calls for deeper structural treatment, you’ll need to supplement with another contractor.
But they’re miles ahead in terms of speed and efficiency. Our wall section was coated in less than a day with almost no mess, and it cured fast enough within 48 hours.
