Pump station wet wells, manholes, and lift stations operate in some of the most aggressive environments in civil infrastructure. Between biogenic sulfuric acid attack (H2S gas), severe hydraulic turbulence, concrete movement, and continuous liquid immersion, traditional coatings quickly crack, delaminate, or dissolve.
Liquimix provides an Australian-manufactured, field-proven lining system engineered specifically for wastewater and water infrastructure: Civilox-LV100 Deep-Penetrating Epoxy Sealer paired with Tufflon-P80 Pure Polyurea Elastomer.
Step 1: Substrate Sealing with Civilox-LV100
Before applying polyurea to concrete, sealing the porous substrate is essential. Civilox-LV100 is an ultra-low viscosity, 100% solids epoxy primer designed to soak deep into concrete pores:
Step 2: High-Build Seamless Barrier with Tufflon-P80
Applied using hot-spray plural component equipment over primed surfaces, Tufflon-P80 forms a seamless, heavy-duty protective skin:
| Performance Characteristic | Liquimix System (Civilox LV100 + Tufflon P80) | Heavy-Duty Epoxy Linings | Polyurethane Coatings | Cementitious / Mortar Liners | HDPE Sheet Liners |
| Cure Time to Full Immersion | Hours (Gel time: 8 seconds) | 5 to 7 Days | 24 to 48 Hours | 7 to 28 Days | Mechanical Fastening / Anchor |
| Flexibility & Elongation | High (>400% Elongation) | Low (<5–10% Rigid) | Moderate (50–150%) | Rigid (0%) | High (Plastic sheet) |
| Crack-Bridging Capability | Superior (Bridges dynamic micro-cracks) | Poor (Cracks when concrete moves) | Moderate | None (Prone to structural cracking) | Poor at welded joints |
| H2S & Acid Resistance | Outstanding (Immune to biogenic acid) | Moderate to Good (Vulnerable at pinholes) | Moderate to Good | Very Poor (Acid dissolves cement) | Excellent |
| Seamless Monolithic Seal | 100% Monolithic Spray (Zero joints) | Monolithic (Brush / Roller / Spray) | Monolithic Spray | Troweled / Shotcrete | Seamed (Welded joints prone to leaking) |
| Pin-Holing Resistance | Optimized via Civilox LV100 deep penetration | High risk on porous concrete | High risk of CO2 reaction with moisture | N/A | N/A |
| Bypass Pumping Duration | Minimal (Ultra-fast turnaround) | High (Long cure required) | Moderate | Very High | High (Labor intensive) |
| Expected Service Life | 20+ Years | 5 to 10 Years | 7 to 12 Years | 3 to 7 Years | 15+ Years (If mechanical anchors hold) |

A Smarter Approach to Sunken Concrete Repair Uneven or sunken concrete can create serious safety problems, affect drainage and interrupt daily operations in warehouses, factories, driveways and other areas. Although replacing the entire concrete slab is an option, it can be expensive, time-consuming and disruptive. PURL-SJ40 polyurethane slab-lifting foam provides

Introduction: The High Stakes of Secondary Containment in Australia Across Australia’s industrial landscapes—from chemical processing plants in Queensland to mining operations in Western Australia and wastewater facilities in Victoria—storing and processing hazardous materials carries immense responsibility. Concrete bunds, containment sumps, and processing floors act as the crucial last line of
