Part of the OMBRAN underground sewer systems range, it exists to solve a problem municipal engineers and trenchless-rehabilitation contractors face constantly — a house-connection intake has come loose, a joint is leaking, or a section of concrete or vitrified-clay pipe has cracked, but digging up the road above it is either impossible or prohibitively disruptive. The resin is delivered through a shuttering sleeve or sealing bladder positioned by CCTV-guided robotics, injected under pressure, and left to cure in place, rebuilding the connection from the inside.\n\nWhat makes it usable in that environment is the chemistry: it adheres to dry, slightly damp or moist mineral substrates and to GRP laminates, and it will actually harden underwater — a real constraint in sewer work, where a line can rarely be dried out completely even after flow is temporarily locked up. Once cured it delivers structural-grade compressive strength and a wet-concrete bond that meets EN 1542, backed by DIBt general building supervision approval. In the Indian context, this places it squarely in the no-dig/trenchless rehabilitation space that Smart City and AMRUT-linked sewer network upgrades are increasingly specifying, rather than in routine RCC repair work. Because the product ships in pre-packed 2:1 pairs sized for robotic dosing rigs, Space Arc supplies it against specific trenchless-rehabilitation projects and coordinates lead time with the applicator’s crawler/packer crew rather than carrying it as an open-stock repair item.”,”technicalInsight”:”Two numbers explain why this resin is engineered the way it is. First, the working time is only about 20 minutes once the resin is preheated to 40°C — deliberately short, because the material has to be mixed, pumped through the filler plug, and packed into the shuttering before it starts to set inside a robot that the crew cannot see or reach directly; the 2:1 mixing ratio (by both mass and volume) has to be hit precisely, which is why MC-Bauchemie insists packs be emptied completely rather than part-mixed by eye. Second, the consumption figure of 1.76 kg/m²/mm is really a density-linked dosing reference (the mixed density is also 1.76 kg/l) rather than a fixed coverage rate — actual quantity depends on the void geometry the robot is filling, which is why the data sheet explicitly calls for object-specific trials before a project is priced.

The technical insight

Two numbers explain why this resin is engineered the way it is. First, the working time is only about 20 minutes once the resin is preheated to 40°C — deliberately short, because the material has to be mixed, pumped through the filler plug, and packed into the shuttering before it starts to set inside a robot that the crew cannot see or reach directly; the 2:1 mixing ratio (by both mass and volume) has to be hit precisely, which is why MC-Bauchemie insists packs be emptied completely rather than part-mixed by eye. Second, the consumption figure of 1.76 kg/m²/mm is really a density-linked dosing reference (the mixed density is also 1.76 kg/l) rather than a fixed coverage rate — actual quantity depends on the void geometry the robot is filling, which is why the data sheet explicitly calls for object-specific trials before a project is priced. Combined with the ≥2.5 bar injection pressure needed to force-fill damaged zones, the whole system is really a process (equipment, pressure, timing) as much as a product.

Where it is used

• Robotic repair and embedding of house-connection intakes/unions in concrete and vitrified-clay sewer pipes using the PE-shuttering technique
• Rehabilitation of longitudinal and circumferential cracks and disruptions in non-man-entry wastewater pipelines
• Sealing and filling of leaking pipe joints and sleeves within sewer networks
• Force-fit annular filling between the host pipe and shuttering sleeve during CCTV-robot-controlled sewer point repair
• Trenchless point repairs on municipal sewer mains beneath live roads, deep interceptors, or other no-dig zones
• Repair works carried out as part of MC-Bauchemie’s broader OMBRAN underground sewer rehabilitation programme
• Injection repair on substrates that stay damp or where standing groundwater infiltration cannot be fully stopped before grouting
• Sealing GRP liner joints in sewer sections that have already been relined

Key advantages

• Hardens even underwater and on moist substrates — critical because sewer lines can rarely be dried out completely before repair
• High compressive strength (≥80 N/mm²) and E-modulus (≥7,000 N/mm²) for repairs that have to carry long-term soil and traffic loading
• Adhesive bond of ≥3.2 N/mm² to wet concrete (EN 1542) — tested in the exact damp conditions a sewer actually presents
• German general building supervision (DIBt) approval gives specifiers and municipal authorities a recognised technical basis for sign-off
• Distinctive anthracite-grey colour makes the finished repair optically identifiable during post-repair CCTV inspection
• Precise 2:1 mixing ratio supplied in pre-packed pairs of cans, reducing on-site batching error compared to open-bag systems
• High chemical resistance suited to aggressive wastewater exposure, including sulfates and detergents
• One resin system that bonds to concrete, ceramics and GRP laminates across mixed-material sewer networks

Limitations & considerations

• Needs specialised robotic/packer shuttering equipment and a trained crew — this is not a product a general mason or waterproofing contractor applies by hand
• Working time of only around 20 minutes (with resin preheated to 40°C) leaves little room for error and demands an experienced operator
• Standing water at the substrate is not permitted even though damp or moist substrates are fine, so active flow has to be temporarily locked up first
• Full cure takes roughly 3.5-5 hours before the line can be put back into service, which usually means bypass pumping or flow diversion for that window
• Stated consumption (1.76 kg/m²/mm) is a density-linked reference, not a fixed coverage rate — object-specific trials are recommended before quoting a job
• Pack sizes (2.8 l pairs, 0.5 l foil bags, 50 kg pairs) are sized for robotic dosing systems, so it is procured per project rather than kept as general site stock

How we position MC-Bauchemie Konudur Robopox 10
