Key Features & Benefits:

Ultra-High Flowability: Easily fills complex voids, narrow cavities, and annular spaces behind linings or around structures with minimal effort.

Controlled Set Time: Adjustable set characteristics (standard & accelerator options available) to suit project schedules and pumping requirements.

High Early & Ultimate Strength: Provides rapid structural support and long-term load-bearing capacity.

Minimal Bleed & Shrinkage: Ensures complete cavity filling without voids or settlement, preventing future structural weaknesses or water pathways.

Pumpability: Excellent consistency for efficient placement using standard grout pumps over significant distances and heights.

Durability: Resists erosion, chemical attack (sulfate-resistant option available), and freeze-thaw cycles.

Eco-Friendly: Low-dust formula, non-toxic, and compliant with environmental regulations.

Primary Application Scenarios:

Tunneling & Microtunneling:

Annular space grouting behind segmental linings (TBM, Pipe Jacking).

Backfilling around conduits, pipes, and casings.

Stabilization of ground behind tunnel linings.

Filling voids around shafts and portals.

Mining:

Backfilling stopes and mined-out areas for ground support and subsidence control.

Sealing old workings and voids.

Consolidation of fragmented rock.

Filling around pillars and infrastructure.

Civil Engineering & Infrastructure:

Backfilling behind retaining walls, abutments, and foundations.

Filling voids under slabs, pavements, and bridge approaches.

Stabilizing soil and rock around buried structures (culverts, tanks).

Repairing sinkholes and subsidence areas.

Utilities & Pipelines:

Annular space grouting around pipelines (water, sewer, oil/gas) in trenchless installations (HDD, Direct Pipe).

Encasement and protection of pipelines and conduits.

Sealing around pipe penetrations through walls and structures.

 

Geotechnical Applications:

Filling large cavities and solution features in rock.

Slope stabilization and underpinning.

Creating grout curtains or barriers (in specific formulations).

 

Packaging & Handling:

Available in 25 kg (55 lb) moisture-resistant paper bags or 1-ton bulk bags (Big Bags).

Store in a cool, dry place on pallets off the floor. Keep bags sealed until use.

Mix with clean, potable water using a high-shear colloidal or paddle mixer according to specified water ratios.

Safety: Always wear appropriate PPE (dust mask, gloves, eye protection) when handling dry powder. Consult Safety Data Sheet (SDS) before use.
