Components made of polymer concrete outperform similar components made from ordinary concrete. Strength in tension, compression and flexure ate 3 to 5 times higher and polymer concrete is more tolerant of shock loading. It is more resistant to corrosion than cast iron and strength is basically unaffected by normal exposure to oil, diesel or petrol. The products should however be used in environments where high concentrations of acids or alkalis are regularly inspected. The load bearing specifications as set by the SABS (SABS 558/1973 AND SABS 1115/1976) for conventional (Cast iron) manhole covers are met and in certain cases exceeded. Withstands high mechanical compressive and bending stress. Excellent resistance to chemical attack, smooth surface without pores prevents settling of solids. The material structure is free of capillaries, absorbs no water and does not allow gas diffusion covered by standards and approved by the municipalities and construction authorities.
