iGrout is a proprietary cementitious product that is specifically designed to be pumped over long distances without segregating or settling. iGrout was designed for annulus space grouting and pipe abandonment installations. iGrout has a unit weight that is greater than that of water, thus will displace any water encountered during installation. iGrout can be installed through running water when it is present within the annulus due to groundwater entry through the host pipe resulting from deterioration or displaced joints. This highly-flowable product is designed to minimize the heat generated during hydration which is a critical factor in slip-line and other annulus space grouting installations.
