What curing is required after grouting?

Cover the exposed surface with wet sacks or curing compound and water-cure for at least 7 days to ensure full strength development and prevent early drying shrinkage.

What is the shelf life and storage condition?

The shelf life is 6 months in original unopened packaging. Store in a dry, ventilated place away from moisture, rain and direct sunlight, and keep bags on pallets.

What certifications does LANGUAN H90 have?

LANGUAN products are manufactured under ISO 9001/14001/45001 and certified by CE, SASO and China National Green Building Material. Specific test reports for H90 can be provided upon request.

Do you support OEM or private labeling?

Yes. With 10 factories and 6 million tons annual capacity, we support OEM packaging, private-label bags and customized formulations for large projects.

Key features

90 MPa Final Strength: 28-day compressive strength >= 90 MPa, providing the highest load-bearing capacity in the LANGUAN grout range for bridge bearings and heavy machinery bases.

Ultra-High Early Strength: 1-day strength >= 40 MPa and 3-day strength >= 60 MPa, enabling fast stripping, early loading and shorter construction windows.

Compensated Shrinkage: vertical expansion rate >= 0.02% maintains tight contact with the substrate and prevents gaps after hardening.

Self-Compacting Flow: initial flow value>= 300 mm and 30-minute flow value >= 260 mm fills complex cavities and dense reinforcement without vibration.

Bridge Bearing Specialist: purpose-formulated for secondary grouting of bridge bearings, rails and highway expansion joints where long-term dynamic load resistance is critical.

Heavy Equipment Base Anchoring: delivers reliable bedding and bolt anchorage for turbines, compressors, presses and other critical rotating equipment.

Freeze-Thaw & Chemical Resistance: durable cementitious matrix withstands penetration, freeze-thaw cycles and chemical exposure in harsh infrastructure environments.

Easy On-Site Mixing: single-component powder requiring only 11-13% clean water; mixes to a uniform, lump-free fluid consistency with standard equipment.

Cost-Effective vs. Epoxy: cementitious chemistry avoids expensive two-component resin systems while still meeting >= 90 MPa structural grouting requirements.

AI-Powered supplier vetting

SummaryShanghai Languan New Building Materials Co., Ltd. is described as a developer, manufacturer, and seller of environmentally friendly building decoration materials. Its stated scope covers building materials, floor-related solutions, machinery and equipment, hardware, chemical products, communication equipment, and import/export and technical services. The supplier reports OEM service for well-known brands, quality assurance, documented complaint-handling and corrective-action procedures, and facilities including mixing, self-leveling, and automatic packaging lines. However, it has no available SDK, no stated AI-based decision-management practice, no inventory capability, no overseas warehouse or showroom, and no valid manufacturing-capacity contract with affiliated subcontractors. Financial information is limited to years identified as 2021–2023 without performance values. Certification, customer cases, and detailed customization evidence are not sufficiently documented.

Supplier typeThe supplier is presented as Shanghai Languan New Building Materials Co., Ltd., focused on R&D, production, and sales of environmentally friendly building decoration materials. Its business scope includes building materials, insulation materials, sealing fillers, cement products, machinery, hardware, chemical products, and related sales and import/export activities, supporting classification as a building-material manufacturer and supplier.

After-Sales capabilityThe supplier reports clear procedures and records for corrective and preventive actions and customer complaint handling, and describes providing technical guidance and comprehensive customer services. However, it lacks overseas warehouse and showroom capabilities, so the evidence supports structured service handling but not broad overseas after-sales infrastructure.

R&D capabilityThe company describes R&D activity and the ability to develop new materials using existing technology, and its culture emphasizes innovation. However, it explicitly has no available SDK and has not established an AI model for big-data decision support; these limitations prevent a broad conclusion that its innovation capability exceeds requirements.

Production capacityThe supplier states that it conducts production and lists processing and manufacturing activities, with a mixing line, self-leveling production line, and automatic packaging robot. Quality assurance and documented corrective-action procedures are also reported, although there is no valid contract with affiliated subcontractors and no in-stock capability.

Customization capabilityThe supplier reports OEM services for well-known brands and says it provides solutions for difficult floors, technical guidance, and development of various new materials using existing technology. This directly supports some customization and OEM capability, although the slices do not specify product scope, minimum quantities, lead times, or engineering resources.

Product Q&A

Q:What is the main difference between H60, H80 and H90?

H60 is a general high-strength non-shrink grout (28d >= 60 MPa) for equipment foundations and bridge bearings. H80 is an ultra-fine precision grout with aggregate <= 0.8 mm for micro-cracks and precision equipment. H90 is the highest-strength bearing grout (28d >= 90 MPa) specifically designed for heavy-load bridge bearings and critical infrastructure.

Q:Can H90 be used for applications other than bridge bearings?

Yes. H90 is also suitable for heavy equipment foundations, railway tracks, steel column bases, and structural reinforcement where very high early and final strength are required.

Q:What is the water-to-powder mixing ratio?

Approximately 11-13% by weight, or about 5.5-6.5 liters of clean water per 50 kg bag, depending on the required flowability and ambient temperature.

Q:What is the recommended grouting thickness per pour?

H90 is typically placed in layers of 20-100 mm per pour. For thicker sections or large-volume grouting, please consult our technical team for layered pouring instructions.

Q:How should the substrate be prepared?

The substrate must be solid, clean, and free of oil, dust and loose debris. Moisten the concrete 24 hours before grouting and remove all standing water immediately before pouring.
