Drain stack renewal · Southeast Asia
Renew your vertical pipes. Keep every tile.
We clean and renew drain and waste stacks from the inside, for hotels and residential buildings. In most cases, no walls are opened.
40 seconds: how a stack is renewed from the inside, floor by floor.
The problem
Ageing stacks hide behind your best finishes
Most buildings built 15 to 30 years ago reach this point. The pipes fail long before the finishes do.
Leaks and odours
Corroded and cracked vertical pipes cause water damage, smells and complaints from guests or residents.
Costly repairs
The usual fix means opening walls and ceilings, then rebuilding tiles, bathrooms and kitchens.
Lost time
Rooms closed for weeks, residents disturbed, dust and noise on every floor.
Our approach
A new inner wall, without opening walls
A technique already used in Europe and still rare in Southeast Asia. After cleaning, we brush resin onto the inside of the existing stack, so in most cases there are no walls to open and no tiles to break. Toilets, kitchens and bathroom drains stay connected: nothing to remove or rebuild.
For hotels
- Rooms out of service for a short time, not weeks
- Bathrooms, marble and tiles stay in place
- Toilets and drains stay connected, nothing to remove
- Work planned floor by floor, around your occupancy
- Low noise and dust, so guests stay comfortable
For condominiums and landlords
- Residents stay in their homes during the work
- No rebuilding of private bathrooms and kitchens
- We work from the roof, rarely from inside the homes
- One clear quote, based on a camera inspection
- Fits the building's maintenance plan

Questions
What engineers usually ask us
Do toilets, kitchens and bathrooms stay connected?
Yes. Every branch connection stays open. The resin is applied so that the junctions are not blocked, and each one is checked with a camera after the work. Nothing is removed or rebuilt in the rooms.
Do you need to enter the apartments or rooms?
Rarely. In most cases we work from the roof, through the top of the stack. No toilet or fixture has to be removed.
How do you check the result?
We film the stack before the work and again at the end. You keep the before and after footage for your records.
Do guests or residents have to leave?
No. They stay in place. Only the drains connected to the stack are out of use for short periods while it is being treated.
