Resin
In substitute for traditional Portland cement, the resin acts as the glue, the bonder that holds the structure together.
Precast Polymer Concrete (PPC)
Vertical Structures
Aggregate
Our precast polymer concrete material is fabricated with inert aggregate, non-reactive in an acidic environment. Our sand as well as our aggregate are selected to be completely corrosion proof and most resistant to compressive stress.

Fiberglass Rebar
Acid resistant FRP bars are used as reinforcement. With a life span of more than 100 years, MST-BAR® is a more durable solution over galvanized, epoxy coated and stainless steel. Approved & Manufactured in compliance with CSA S807 & ACI 440.

Corrosion Proof
Hydrogen sulfide gas (H₂S) oxidizes to sulfuric acid (H₂SO₄), creating corrosion in wastewater systems. H₂S is generated by bacterial growth from the waste feeds on the structure and oxidizes to H₂SO₄. Acid attacks the cement (glue) in the concrete causing deterioration. Depending on the aggregate source, acid can also attack that component of the traditional concrete mix. Once corrosion begins, the integrity of the structure is compromised.
Material Strength
PPC material is as versatile as traditional concrete, but resists corrosion and has higher performance qualities. PPC is superior when comparing multiple properties that are critical when comes the time to select the best solution for your wastewater systems. The material properties of Armorock PPC manholes and structures adhere to the criteria specified in ASTM D-6783. PPC is 8 times stronger in flexural and 4 times stronger in compression.
Sustainability
The design of our precast polymer concrete structures are build to last without compromising the performance level throughout the year. This results in a low life-cycle cost, making polymer concrete a cost-effective choice. Minimizing the number of interventions and maintenance efforts has not only a positive financial impact, but also on environment, the safety of our workers and users, and the well-being of the community.
Easy Installation
Installation is similar to that of a traditional concrete storm drain manhole. With custom structures, we optimize the design to deliver the precast product in sections to make the contractor's life easier. Our products are designed for ease of installation and with safety considerations for the workers. Novinfra's team will support you every step of the way to make sure the installation is a success.
PPC Maintenance Hole
Our polymer concrete maintenance holes range from 36" to 192" and we can provide precast maintenance hole bases. Available in circular and non-circular designs.
Rehabilitation Inserts
This solution allows you to rebuild a "new" structure from inside your existing system.
Lift Stations
Polymer concrete resolves the challenge of H2S exposure to lift stations.
Tanks / Cells
The properties of polymer concrete make it an ideal material for building structures that are exposed to acidic solutions in the mining process.
Custom Structures
Base rule: whatever you can produce in traditional concrete, you can do in polymer concrete.
