Colcrete mortar is a highly durable grouting compound made from cement, water and aggregate. Produced in a completely mechanical process, it contains no chemical additives. Its colloidal properties come from thoroughly mixing in a special Colcrete mixer. Once prepared, Colcrete mortar does not bond with water molecules, so there is no segregation under water. Its flow and pumping properties are excellent and its adhesive properties good. When set, Colcrete mortar is waterproof. It is resistant to mechanical attack by waves and tides and withstands chemical attack by river pollutants or seawater.
