Concrete Protection
Concrete Protection Liner
A cutting-edge solution for safeguarding concrete wastewater infrastructure is the embedded High-Density Polyethylene (HDPE) Concrete Protection Liner (CPL). This technology distinguishes itself by incorporating anchors on its back that securely embed into the concrete, effectively becoming an integral structural component. This unique feature ensures a design life that aligns with that of the structure, negating the necessity for ongoing maintenance and its associated costs.
The HDPE Concrete Protection Liner stands out for its chemical resistance to standard wastewater streams, providing a dual protective shield. It effectively combats Microbial-Induced Corrosion (MIC) caused by hydrogen sulfide and acid-producing bacteria, while also preventing inflow and infiltration. Remarkably, it is the exclusive technology capable of delivering secondary containment within piping systems. In the event of a primary gasket failure or concrete cracks, the system remains impervious to infiltration and inflow, offering unparalleled security.
Concrete Protection Liner Vs. Spray Applied Coating
Concrete Protection Liner (CPL) differs significantly from spray-applied coatings in several key aspects:
Integration into Structure:
- CPL: Embeds directly into cast concrete, becoming an integral part of the structure.
- Spray-Applied Coating: Functions as a surface bond, lacking integration into the concrete structure.
Surface Preparation:
- CPL requires no surface preparation before application.
- Spray-Applied Coating requires surface preparation prior to application.
Moisture Content:
- CPL: Can be applied to concrete with higher moisture content without restrictions on relative humidity during application.
- Spray-Applied Coating: Limited by relative humidity restrictions during application.
Longevity:
- CPL: Lasts the entire lifespan of the structure.
- Spray-Applied Coating: Requires periodic replacement.
Back Pressure Ratings:
- CPL: Outperforms in back pressure ratings while matching industry norms.
- Spray-Applied Coating: Has low back pressure ratings.
Secondary Containment:
- CPL: Offers secondary containment, reducing the risk of infiltration and inflow in the event of concrete pipe or structure cracking.
- Spray-Applied Coating: lacks secondary confinement characteristics.
In summary, Concrete Protection Liner offers enhanced integration, application flexibility, durability, and additional protective features compared to spray-applied coatings.
