Think of a pipe running under a live arterial road, a railway embankment, or the foundation of an occupied building: cracked, root-infiltrated, leaking at every joint, and utterly impractical to dig up. Konudur HL 11 PP is the needle-punched polyester felt hose, PP-foil faced, that gets impregnated with reaction resin and pulled inside-out through that pipe by water or air pressure until it presses flush against the old pipe wall and cures into a new, jointless conduit — a pipe within a pipe, installed from a single access manhole.\n\nWhat makes it a genuine engineering material rather than a generic liner is the calibration behind every number on its data sheet: felt grammage from 450 to 1,050 g/m² per layer depending on the wall thickness required, a PP-coating held to a ±10% tolerance across the DN150-600mm range, and inversion and vacuum pressures that are deliberately specified as bands rather than fixed values because every host pipe’s diameter, ovality and defect profile is different. It is a project-engineered component, sold and installed against a specific pipe survey, not a stock item pulled off a shelf. For Space Arc, as an authorised MC-Bauchemie distributor and applicator, it sits at the specialist end of the repair-and-rehabilitation portfolio — supplied and coordinated for municipal, industrial and infrastructure clients who need trenchless sewer renewal rather than surface-level structural repair.”,”technicalInsight”:”The PP foil is doing more than branding: as the CIPP hose is impregnated and then everted through the host pipe, that foil ends up forming the smooth, low-friction, chemically resistant bore of the finished liner while also acting as the pressure membrane that holds inflation air or water against the curing resin. That is why grammage, wall thickness and inflation pressure are all specified together in the data sheet — get any one wrong relative to the host pipe’s actual diameter and wall thickness, and the liner either undersizes, wrinkles, or fails to cure evenly. The ~10% liner-undersize allowance and the 0.2-0.6 bar inversion-pressure band are MC-Bauchemie’s acknowledgement that this is a live, condition-dependent installation, not a fixed-dimension product — which is exactly why it is specified and supplied per project rather than off a catalogue shelf.”,”applications”:[“Trenchless (no-dig) rehabilitation of cracked, fractured or root-intruded municipal sewer mains and laterals, DN150-600mm”,”Renewal of corroded RCC, stoneware or cast-iron underground drainage pipes without open-cut excavation”,”Relining industrial effluent and process-water ducts where shutting a plant for open-cut repair is not viable”,”Restoring hydraulic capacity and joint-tightness in ageing sewer networks prone to groundwater infiltration/exfiltration”,”Rehabilitating stormwater culverts and box drains running beneath live carriageways, railway tracks or runways”,”Sewer lines beneath occupied buildings, heritage structures or congested utility corridors where excavation risk is unacceptable”,”Manhole-to-manhole sewer renewal as part of MC-Bauchemie’s wider Ombran/Konudur Homeliner CIPP system”],”advantages”:[“Genuinely trenchless — removes the excavation, traffic disruption and reinstatement cost of open-cut sewer replacement”,”Wide diameter coverage, DN150-600mm with larger sizes on request, spans most municipal lateral and trunk sewer sizes”,”PP-foil face gives a smooth, low-friction finished bore that can improve flow capacity versus the corroded host pipe it replaces”,”Needle-felt structure impregnates evenly, with resin consumption (~1.0 l/m²/mm) given as a clear planning guideline”,”Cures in place at up to +115°C into a continuous, jointless liner with no infiltration-prone joints”,”Stable minimum one-year shelf life under correct dry, dust-free, UV-protected storage supports project scheduling”,”Part of MC-Bauchemie’s complete Ombran ecosystem — impregnation resins, manhole connection sealants (Konudur Flexfit) and structure repair mortars from one accountable system”],”limitations”:[“It is a substrate/textile component, not a ready-to-lay liner — must be impregnated with a compatible reaction resin and engineered per pipe before installation”,”Installation needs specialist CIPP inversion equipment and a trained crew; this is not general-contractor or DIY material”,”Liner performance depends heavily on matching diameter, wall thickness, vacuum and inversion pressure to the actual host-pipe condition — under-specification risks sag or wrinkling”,”Rated service temperature is +70°C based on potable-water testing; aggressive sewage chemistry can reduce this, so the impregnation resin must be matched to actual effluent conditions”,”Being cut and supplied to a project-specific diameter and length, lead times and minimum order quantities run longer than shelf-stocked repair mortars”,”Pricing and availability in India are quoted per project against a pipe survey, not off a standard rate card”],”bestPractice”:”Commission a proper pipe/CCTV survey before ordering — diameter, ovality and defect extent decide both the DN and wall-thickness selection, and Konudur HL 11 PP is cut to length with explicit allowance for liner ends, the vacuum connection and the resin filling port, so under-ordering length is a common and costly mistake. Store the felt hose at +15°C to +20°C, dry, dust-free and shielded from UV before use; it holds for at least a year under those conditions but degrades faster outside them. Always work from MC-Bauchemie’s “General Application Advice for CIPP Liner Systems” and the “Konudur Homeliner” application manual for vacuum, impregnation and inversion pressures rather than improvising, and impregnate the felt fully and evenly with the specified reaction resin before installation — partial saturation is the single biggest cause of in-service liner defects.

The technical insight

The PP foil is doing more than branding: as the CIPP hose is impregnated and then everted through the host pipe, that foil ends up forming the smooth, low-friction, chemically resistant bore of the finished liner while also acting as the pressure membrane that holds inflation air or water against the curing resin. That is why grammage, wall thickness and inflation pressure are all specified together in the data sheet — get any one wrong relative to the host pipe’s actual diameter and wall thickness, and the liner either undersizes, wrinkles, or fails to cure evenly. The ~10% liner-undersize allowance and the 0.2-0.6 bar inversion-pressure band are MC-Bauchemie’s acknowledgement that this is a live, condition-dependent installation, not a fixed-dimension product — which is exactly why it is specified and supplied per project rather than off a catalogue shelf.

Where it is used

• Trenchless (no-dig) rehabilitation of cracked, fractured or root-intruded municipal sewer mains and laterals, DN150-600mm
• Renewal of corroded RCC, stoneware or cast-iron underground drainage pipes without open-cut excavation
• Relining industrial effluent and process-water ducts where shutting a plant for open-cut repair is not viable
• Restoring hydraulic capacity and joint-tightness in ageing sewer networks prone to groundwater infiltration/exfiltration
• Rehabilitating stormwater culverts and box drains running beneath live carriageways, railway tracks or runways
• Sewer lines beneath occupied buildings, heritage structures or congested utility corridors where excavation risk is unacceptable
• Manhole-to-manhole sewer renewal as part of MC-Bauchemie’s wider Ombran/Konudur Homeliner CIPP system

Key advantages

• Genuinely trenchless — removes the excavation, traffic disruption and reinstatement cost of open-cut sewer replacement
• Wide diameter coverage, DN150-600mm with larger sizes on request, spans most municipal lateral and trunk sewer sizes
• PP-foil face gives a smooth, low-friction finished bore that can improve flow capacity versus the corroded host pipe it replaces
• Needle-felt structure impregnates evenly, with resin consumption (~1.0 l/m²/mm) given as a clear planning guideline
• Cures in place at up to +115°C into a continuous, jointless liner with no infiltration-prone joints
• Stable minimum one-year shelf life under correct dry, dust-free, UV-protected storage supports project scheduling
• Part of MC-Bauchemie’s complete Ombran ecosystem — impregnation resins, manhole connection sealants (Konudur Flexfit) and structure repair mortars from one accountable system

Limitations & considerations

• It is a substrate/textile component, not a ready-to-lay liner — must be impregnated with a compatible reaction resin and engineered per pipe before installation
• Installation needs specialist CIPP inversion equipment and a trained crew; this is not general-contractor or DIY material
• Liner performance depends heavily on matching diameter, wall thickness, vacuum and inversion pressure to the actual host-pipe condition — under-specification risks sag or wrinkling
• Rated service temperature is +70°C based on potable-water testing; aggressive sewage chemistry can reduce this, so the impregnation resin must be matched to actual effluent conditions
• Being cut and supplied to a project-specific diameter and length, lead times and minimum order quantities run longer than shelf-stocked repair mortars
• Pricing and availability in India are quoted per project against a pipe survey, not off a standard rate card

How we position MC-Bauchemie Konudur HL 11 PP

Within MC-Bauchemie’s own range, Konudur HL 11 PP is one half of a system: it pairs with impregnation resins from the Konudur line, with Konudur Flexfit (a two-component reaction-resin filler and sealant used to seal the liner into manhole connections), and with ombran-brand mineral repair mortars such as ombran MHP-SP 3000 for the accessible manhole structures at either end of the lined run — together forming MC-Bauchemie’s manhole-to-manhole Ombran/Konudur Homeliner sewer rehabilitation system. Where a project needs a PVC-faced finish instead, Konudur HL 11 PVC is the direct sibling variant. There is no genuine Fosroc equivalent worth naming here: Fosroc’s Indian portfolio covers repair mortars, waterproofing membranes and manhole/structure coatings, but not CIPP inversion liner textiles for trenchless pipe renewal — that is a specialist trenchless-technology category served by CIPP-specific suppliers, not by the general repair-mortar brands Space Arc typically cross-references. Specifiers evaluating this product are usually comparing it against other CIPP liner-hose suppliers on pipe-survey terms (diameter, resin compatibility, installed cost per metre), not against a shelf-stocked construction chemical.
