CAPCO was established in 2003 with the aim of producing polymer and chemical products in the construction industry. In the first step, plastic spacers were produced for almost all of the reinforced concrete elements. CAPCO company is the biggest producer of concrete plastic spacers in Iran. The design unit of the company, designs more than 50 injection molds for new plastic spacers annually. Production of PVC sealing strips (waterstops) has been generated in the second step. This product has an important role in water and wastewater projects and requires high quality based on the determined Standards. For the first time in Iran, CAPCO company published a national Iranian standard (ISIRI 13277) for concrete waterstops. Concrete chemical admixtures are another category of products in the product portfolio of CAPCO company. These products are of great importance in today's concrete projects and CAPCO has defined a good perspective in this market for itself.
