MC-Bauchemie Konudur 170 TR
MC-Bauchemie’s tropical-grade CIPP liner resin, engineered to cure reliably in the high ambient and ground temperatures typical of Indian sewer-rehabilitation sites.
What is it?
A two-component, low-viscosity epoxy resin from MC-Bauchemie’s OMBRAN underground sewer systems range, purpose-built to impregnate polyester needle-felt tubes used in Cured-In-Place-Pipe (CIPP) liner installations.
Where is it used?
Non-accessible (non-man-entry) sewer and drainage pipelines undergoing trenchless, no-dig rehabilitation — municipal wastewater networks, storm-water drains, industrial effluent lines and utility ducts where open-cut excavation is impractical.
Why use it?
Its thermo-reactive (“TR” = tropical) chemistry is tuned to cure reliably and quickly at the elevated ambient and ground/water temperatures typical of Indian conditions, where standard ambient-cure resins can gel too fast on site or cure unevenly, risking wrinkles, resin-starved zones or liner failure.
How is it applied?
Component A (resin) and Component B (hardener) are metered and mixed in a dedicated CIPP wet-out/impregnation unit, vacuum- or roller-impregnated into the felt liner tube under controlled pressure, then the saturated liner is winched or inverted into the host pipe and cured in place with hot water, steam or UV per standard CIPP practice.
About MC-Bauchemie Konudur 170 TR
Konudur 170 TR sits inside MC-Bauchemie’s OMBRAN range for underground sewer systems, in the sub-family built specifically for Cured-In-Place-Pipe (CIPP) rehabilitation of non-accessible — meaning non-man-entry — sewer and drainage pipelines. CIPP is the standard no-dig method for renewing an ageing pipe from the inside: a resin-saturated felt tube is pulled or inverted into the host pipe, inflated against the pipe wall, and cured in place to form a tight-fitting structural liner, all without cutting open the road above. The resin used to saturate that felt tube is not incidental to the process — its viscosity, pot life and cure profile decide whether the liner wets out evenly, holds its shape during cure, and reaches design strength on schedule. Konudur 170 TR is the tropical-climate member of MC-Bauchemie’s Konudur 170 resin family, purpose-formulated for exactly the site conditions Indian contractors deal with through most of the year.
On site, the two components are metered and mixed in a dedicated CIPP wet-out unit, then rolled into the felt tube under controlled pressure; the resin’s light-blue tint makes uneven or under-saturated patches visible during this quality check, before the liner ever goes into the ground. Once cured, it bonds to the range of substrates a rehabilitation crew actually finds inside old sewers — concrete, brick, ceramic pipe and metallic sections — and is formulated to perform on pipe walls that are damp rather than bone dry, which matters given that a completely dry host pipe is rarely achievable on a live wastewater line. MC-Bauchemie has REACH-assessed the resin for long-term water contact and periodic inhalation exposure, relevant given the product’s end use inside pipework carrying wastewater and stormwater.
The technical insight
The “TR” in the name stands for tropical, and it is the whole point of the formulation. Most CIPP epoxies are calibrated around temperate-climate installation windows; push their reaction kinetics into a 35-40°C Indian summer ambient, or warm groundwater infiltrating the host pipe, and pot life can collapse faster than the wet-out and inversion sequence allows — risking a liner that gels before it’s fully saturated or positioned. Konudur 170 TR’s thermo-reactive chemistry is recalibrated the other way: it’s designed to hold a workable pot life at elevated temperatures while still using that same warmth to drive a faster, more complete cure once the liner is in place, rather than fighting the climate. That’s the practical reason a distributor stocks both the TR and the standard-temperature BT variant side by side — the right one depends on the ambient and infiltration-water temperature the crew will actually be working in, not a general preference.
Where it is used
- Trenchless CIPP lining of non-man-entry municipal sewer mains and lateral connections
- Storm-water drain rehabilitation without cutting open the carriageway
- Renewal of ageing vitrified clay, concrete and cast-iron sewer pipelines
- Relining of industrial effluent and process drainage pipework
- Culvert and buried utility duct renovation in high-ambient-temperature site conditions
- Impregnation of polyester needle-felt liners for inversion or pull-in-place CIPP installation
- No-dig rehabilitation under busy roads, live utilities or heritage-restricted zones
- Resin component within larger OMBRAN sewer-network rehabilitation programmes
Key advantages
- Cure kinetics tuned to Indian ambient and groundwater temperatures rather than temperate-climate defaults
- Low viscosity for thorough, void-free saturation of the felt liner
- Light-blue pigmentation makes impregnation quality visible before the liner is installed
- Bonds well to concrete, brick, ceramic and metallic host-pipe substrates
- Performs on damp as well as dry pipe walls, cutting pre-drying downtime
- Part of an engineered, REACH-assessed OMBRAN system rather than a generic epoxy substitute
- Works with automated CIPP wet-out/impregnation equipment for consistent large-diameter runs
- No-dig installation avoids road cutting, traffic disruption and reinstatement cost
Limitations & considerations
- A specialist liquid resin for calibrated CIPP wet-out equipment and trained crews — not a hand-applied patch or repair mortar
- Exact mixing ratio, pot life, gel time and cured strength figures are formulation/batch specific and must be confirmed from MC-Bauchemie’s current datasheet before dosing
- Its warm-cure profile is matched to tropical conditions; cooler or high-altitude sites are usually better served by the standard-temperature Konudur 170 BT variant
- Resin performance cannot compensate for a poorly surveyed host pipe or incorrectly sized liner — CCTV survey and correct liner selection remain the contractor’s responsibility
- As a two-component epoxy, mixing and impregnation call for standard 2K-epoxy PPE, ventilation and skin-contact precautions
- A specialist, imported system component — lead time and technical coordination need to be built into the project schedule rather than treated as shelf stock
Selection & best practice
Confirm the host pipe’s condition and diameter with a current CCTV survey before finalising liner and resin quantities, and check actual site and infiltration-water temperature against MC-Bauchemie’s recommended range for Konudur 170 TR rather than assuming it’s the right variant by default. Mix and impregnate strictly through a calibrated CIPP wet-out unit — this resin is not meant for hand-mixing — and use the light-blue colour as a visual check for uniform, void-free saturation across the full liner length before inversion or pull-in. Always work off the latest technical and safety data sheets from MC-Bauchemie for the exact mixing ratio, pot life and cure schedule for the batch in hand, since epoxy formulations are periodically revised, and hold back cured-sample verification (per standard CIPP QA practice) before reinstating flow through the rehabilitated line.

How we position MC-Bauchemie Konudur 170 TR
Konudur 170 TR belongs to MC-Bauchemie’s Konudur 170 resin family within its OMBRAN underground sewer systems platform — sitting alongside Konudur 170 BT (the standard-temperature counterpart for cooler site conditions), the TR-NA and TL-NV variants formulated for related site scenarios, Konudur Flexfit for rehabilitating manholes and accessible chamber structures, and Konudur Robopox for fast-curing robotic point-repairs within a lined pipe. Specified together, these cover a full non-man-entry sewer rehabilitation programme from mainline CIPP lining through to chamber and spot repair, all under one manufacturer’s system responsibility. There isn’t a genuine like-for-like Fosroc equivalent to name here — Fosroc’s Indian range is built around above-ground and accessible concrete repair (the Renderoc and Nitomortar families), waterproofing and flooring rather than CIPP liner-impregnation resins, so trenchless sewer rehabilitation specifiers should treat this as a specialist, single-source OMBRAN category; Fosroc’s repair mortars remain the relevant reference point for any accessible-chamber or manhole repair scope sitting alongside this pipeline work.
