ENGINEERING SPECIFICATIONS

Key Features & Structural Design

Centrifugally spun concrete yields ultra-dense compaction and smooth internal finish
High-grade reinforcement steel cage embedded within rich cement matrix
Exceptional compressive strength capable of withstanding heavy surface vehicle loads
Factory-cured under controlled atmospheric conditions for uniform strength
Ready-to-install precast units delivered directly to the construction site
Integrated baffle divisions for effective anaerobic settling

Operational Benefits

Can be placed beneath car parking bays, driveways, and heavy traffic zones

Pore-free inner walls prevent subterranean sewage leaching into nearby drinking wells

Zero on-site masonry work or shuttering required, saving weeks of construction time

Tremendous structural stability resistant to earth tremors and soil vibrations

Recommended Applications

Urban plots where the septic tank must be located beneath vehicle driveways/porches
Apartment complexes, residential townships, and educational institutions
Industrial estates, factories, and warehouses with heavy vehicle traffic
Hospitals and commercial buildings requiring robust underground containment
