Prefabricated reinforced concrete (RC) combined septic tanks are not restricted by seasonal changes. They are especially suitable for areas with high groundwater levels, poor soil bearing capacity, and loose soil prone to collapse. Using prefabricated circular RC combined septic tanks reduces slope coefficients and avoids large-scale trench excavation. This not only minimizes earthwork but also eliminates the need for foundation pit support procedures, saving both labour and materials.

The installation process is straightforward and efficient, requiring only 3–4 hours to complete. It simplifies construction and addresses longstanding issues such as leakage, collapse, environmental pollution, and lengthy construction periods. As a result, these septic tanks truly embody the principles of green and sustainable construction.
Our moulds come in the following capacities:
6 m³, 10 m³, 12 m³, 16 m³, 20 m³, 25 m³, 30 m³, 40 m³, 50 m³.
High Strength, Rigidity, and Stability: Accurate in shape and dimensions with consistently high installation precision.
Ease of Assembly and Disassembly: Reliable positioning and convenient maintenance.
Mass Production Capability: Designed for factory-based large-scale production with high reuse cycles, suitable for steam-curing environments (humid conditions).
Excellent Surface Finish: Meets exposed and decorative concrete requirements.
Reasonable Design: Ensures long service life and prevents slurry leakage.
Mould Maintenance
Regularly clean and inspect the moulds during use to prevent residual concrete from affecting the surface quality of the components.
Use of Release Agent
Before each concrete casting, evenly apply a release agent to ensure smooth demoulding and prevent surface damage.
Operational Standards
Follow standard procedures during concrete pouring and vibration to prevent air bubbles and cracks, ensuring the quality of the components.
With rational design and efficient construction, cement septic tank moulds are an ideal solution and should be widely promoted for use in various projects.
