Cast-In-Place
Cast-In-Place CPL Solution
Durable Protective Barrier with Seamless Integration
A cast-in-place solution (also known as poured-in-place) refers to the smooth side of the Concrete Protection Liner (CPL) placed against the inside of a form before pouring concrete. The anchors face inwards so that the concrete consolidates around them during the pour and the concrete then cures around the anchors.
In a cast-in-place solution, the Concrete Protection Liner protects against concrete corrosion. It creates a durable barrier that shields the concrete from corrosive media. This extends the life of concrete structures in both above-grade and below-grade infrastructure. In addition, the CPL can be used in both exposed and nonexposed applications.
Benefits of Cast-In-Place CPL:
- Durability: A cast-in-place CPL solution extends the life of the infrastructure by protecting the concrete from concrete corrosion or concrete degradation stemming from microbial-induced corrosion (MIC), hydrogen sulfide attack, chemical attack, abrasion, and physical damage.
- Customization: A cast-in-place CPL solution can be utilized with any tank or structure shape and can also be made from a variety of thicknesses to accommodate the specific needs of the application.
- High-Performance Life: Concrete Protection Liner in a cast-in-place solution increases the design life of the structure, requiring no future or ongoing maintenance.
- Cost Savings: Unlike spray coatings, CPL does not need to be reapplied over time. Using CPL reduces the total cost of ownership of wastewater transmission systems.
Applications Cast-In-Place CPL:
- Municipal and Agricultural Digesters: Protects against biogas, acidic conditions, and thermal variations.
- Water Treatment Plants: Shields against microbial induced corrosion, hydrogen sulfide attack, chemicals, and biological growth.
- Wastewater Systems: Prevents concrete from concrete corrosion or concrete degradation stemming from microbial induced corrosion, hydrogen sulfide attack, inflow and infiltration. Public utilities reinforced concrete pipe.
- Storage Tanks: Guards against chemical attacks and provides secondary containment, assuring additional environmental protection.
Material Options
Concrete Protection Liner, made from high-density polyethylene (HDPE) is the most commonly used material and covers the widest range of applications for cast-in-place solutions.
For extreme conditions with either high temperatures or an extremely corrosive media, Concrete Protection Liner is also available in polypropylene, polyvinylidene difluoride (PVDF), and ethylene chlorotrifluoroethylene (ECTFE) with temperature ranges from -30° C to +140° C.
