Polymer concrete

Polymer concrete is part of group of concretes that use polymers to supplement or replace cement as a binder. The types include polymer-impregnated concrete, polymer concrete, and polymer-Portland-cement concrete. Polymers in concrete have been overseen by Committee 548 of the American Concrete Institute since 1971.

In polymer concrete, thermosetting resins are used as the principal polymer component due to their high thermal stability and resistance to a wide variety of chemicals. Polymer concrete is also composed of aggregates that include silica, quartz, granite, limestone, and other high quality material. The aggregate must be of good quality, free of dust and other debris, and dry. Failure to fulfill these criteria can reduce the bond strength between the polymer binder and the aggregate.


Polymer concrete may be used for new construction or repairing of old concrete. The adhesive properties of polymer concrete allow patching of both polymer and conventional cement-based concretes. The low permeability and corrosive resistance of polymer concrete allows it to be used in swimming pools, sewer structure applications, drainage channels, electrolytic cells for base metal recovery, and other structures that contain liquids or corrosive chemicals. It is especially suited to the construction and rehabilitation of manholes due to their ability to withstand toxic and corrosive sewer gases and bacteria commonly found in sewer systems. Unlike traditional concrete structures, polymer concrete requires no coating or welding of PVC-protected seams.[1] It can also be used as a bonded wearing course for asphalt pavement, for higher durability and higher strength upon a concrete substrate. Companies such as North American Poly Supply Company, Inc. have developed means to provide polymer concrete for structural concrete overlay and rehabilitation applications in conjunction with a methacrylate primer with costs economically suitable for public road and highway departments. Further developments in polymer concrete may lead to common usage of the material in additional infrastructure applications. [2]

Polymer concrete has historically not been widely adopted due to the high costs and difficulty associated with traditional manufacturing techniques. However, recent progress has led to significant reductions in cost, meaning that the use of polymer concrete is gradually becoming more widespread.[3][4]


Advantages of polymer concrete include:

  • Rapid curing at ambient temperatures
  • High tensile, flexural, and compressive strengths
  • Good adhesion to most surfaces
  • Good long-term durability with respect to freeze and thaw cycles
  • Low permeability to water and aggressive solutions
  • Good chemical resistance
  • Good resistance against corrosion
  • Lighter weight (only somewhat less dense than traditional concrete, depending on the resin content of the mix)
  • May be vibrated to fill voids in forms
  • Allows use of regular form-release agents (in some applications)
  • Dielectric


Product hard to manipulate with conventional tools such as drills and presses due to its strength and density. Recommend getting pre-modified product from the manufacturer

Small boxes are more costly when compared to its precast counterpart however pre cast concretes induction of stacking or steel covers quickly bridge the gap.
