MC-Bauchemie Konudur 180 PW
MC-Bauchemie’s epoxy resin that turns a felt liner into a drinking-water-safe pipe inside an old, corroding water main — without digging up the road.
What is it?
A two-component, thermo-reactive epoxy resin used to impregnate the felt/GRP liner hose in CIPP (Cured-In-Place Pipe) rehabilitation of pressurised drinking-water pipelines.
Where is it used?
Underground potable-water trunk mains and distribution pipes — cast-iron, ductile-iron, steel and cement-lined lines being relined by trenchless contractors and water utilities.
Why use it?
Lets a leaking or corroded water main be relined from inside, in place, avoiding road-cutting, traffic disruption and the cost of dig-and-replace.
How is it applied?
Vacuum-impregnated into the matched Konudur HL 31 PE hose, the wetted liner is winched or inverted into the host pipe, then thermally cured in place.
About MC-Bauchemie Konudur 180 PW
Konudur 180 PW is a specialist resin, not a general-purpose repair product — it’s the epoxy half of MC-Bauchemie’s Konudur PW-Liner system, built specifically for trenchless (no-dig) rehabilitation of potable-water pressure pipes. City water networks across India are ageing: cast-iron and asbestos-cement mains laid decades ago are now leaking, corroding internally, or discolouring supply, and digging up arterial roads to replace them is often neither affordable nor permitted. CIPP lining addresses that directly — a resin-saturated liner hose is pulled or inverted into the damaged pipe and cured in place, effectively creating a new pipe within the old one.
For Space Arc, this sits at the specialist end of the MC-Bauchemie range we carry. It isn’t a counter-stock item picked up for a site repair job — it’s procured against a confirmed trenchless-rehabilitation contract, typically for municipal Jal Board/Jal Jeevan Mission or AMRUT pipe-renewal work, airports, refineries, or campuses where excavation isn’t an option. We coordinate supply and technical documentation with MC-Bauchemie directly for such projects, working alongside the specialist CIPP installation contractor rather than general site labour.
The technical insight
MC-Bauchemie calls this resin “thermo-reactive” for a reason: the two-component epoxy needs to stay workable long enough to fully saturate a liner hose that can run tens or hundreds of metres, then cure quickly once heat is applied after installation. That long-open/fast-cure split is what makes CIPP practical — installers get a real window to wet-out and handle the liner without it curing prematurely, while the utility gets the main back in service fast. MC-Bauchemie references the finished Konudur PW-Liner system against EN ISO 11295’s Class C category, broadly liners assessed for hydraulic and corrosion-barrier performance rather than independent full structural capacity — which is why a host-pipe condition survey should always precede specification, not follow it.
Where it is used
- Impregnation resin for CIPP liners used in trenchless rehabilitation of potable-water pressure pipelines
- No-dig relining of ageing cast-iron, ductile-iron, steel and asbestos-cement drinking-water mains
- Municipal water-network renewal under Jal Jeevan Mission, AMRUT and smart-city pipe-rehabilitation contracts
- Corrosion-barrier lining inside metallic mains to arrest internal tuberculation and discoloured-water complaints
- Relining water mains beneath roads, railway crossings or other no-excavation-permitted zones
- Used together with the Konudur HL 31 PE hose to form the complete Konudur PW-Liner system
- Institutional and industrial campus potable-water pipe renewal without disrupting operations
Key advantages
- Purpose-built for drinking-water contact, with DVGW-referenced hygiene assessment rather than a repurposed industrial resin
- Long working time gives installer crews a real window to saturate and position long liner runs
- Fast thermal cure once triggered, minimising water-supply downtime for the community served by the main
- Trenchless application avoids road-cutting, traffic disruption and reinstatement cost of dig-and-replace
- Bonds to both mineral and metallic pipe substrates, covering the mixed-material reality of ageing Indian water networks
- Forms a single-source system with the Konudur HL 31 PE hose, simplifying technical accountability
- Backed by MC-Bauchemie’s global CIPP/ombran engineering support for contractors new to trenchless work
Limitations & considerations
- A specialist CIPP wet-out resin, not a trowel or brush-applied repair mortar — needs dedicated impregnation and inversion/pull-in equipment plus trained crews
- Published sources are thin on open numeric values (pot life, viscosity, mixing ratio) — always obtain the current signed TDS and compliance certificate before specifying
- Thermo-reactive cure means site heating or hot-water/steam curing equipment is required, not an ambient-cure convenience
- Purpose-built for buried pressure-pipe rehabilitation — unsuited to cosmetic concrete patch repair despite sitting in a ‘repair’ product listing
- In India, typically a project-specific procurement through MC-Bauchemie’s channel rather than an off-the-shelf dealer-counter pack
Selection & best practice
Treat this as a specification, not a stock item. Get the current signed TDS and drinking-water compliance certificate from MC-Bauchemie/Space Arc before finalising a BOQ, and confirm the matched Konudur HL 31 PE hose diameter for the host pipe. Engage only trained CIPP crews — wet-out, inversion and thermal curing are controlled processes, not manual site work. Verify a CCTV condition survey and EN ISO 11295 class suitability before choosing lining over replacement, and plan the curing cycle and supply shutdown window with the utility in advance.

Is Konudur 180 PW safe for drinking-water pipelines?
Can Space Arc supply this off the shelf like a repair mortar?
What’s the difference between Konudur 180 PW and Konudur HL 31 PE?
Can our regular concrete-repair mason apply this?
Does this remove the need to excavate and replace the old pipe?
We need a faster or ambient-cure option — is one available?
How we position MC-Bauchemie Konudur 180 PW
Konudur 180 PW only performs as specified when paired with the Konudur HL 31 PE hose liner — together they sit inside MC-Bauchemie’s broader ombran underground-pipe rehabilitation programme, alongside the MC-RIM PW 40/80/101/201/301 mineral and shotcrete systems used for larger, accessible potable-water structures. There’s no genuine Fosroc equivalent here: Fosroc’s Indian range is strong on general concrete repair (Renderoc, Nitomortar) and structural grouting (Conbextra), but doesn’t publish a comparable CIPP impregnation resin for trenchless water-main lining. For standard concrete patch repair, Space Arc’s Fosroc range remains a credible alternative — but for CIPP relining of drinking-water mains specifically, MC-Bauchemie’s Konudur system is the relevant specification, and our role is project coordination rather than shelf supply.
