Ultrafine Pozzolanic Cementitious Grout

707 views

Published on

US Grout manufactures Ultrafine and Microfine Cementitious Grouts. Made from Portland cement, pumice, and super-plasticizers, US Grouts are super-charged with natural pumice pozzolan, effectively overcoming the deleterious effects inherent in standard cementitious grouts. US Grout Ultrafine, with an average particle size of 3 microns, will effectively penetrate and seal micro fractures and completely grout dense silty soils. These are truly superior cementitious grouts that have effective application for sealing microfractures in rock, “squeeze” cementing in the petroleum industry, repairing concrete structures, improving the bearing capacity of weak soils, and limiting the migration of contaminants in environmental remediation.
