Watch our short (3 minute) job highlight video below for the product and installation details on this anchoring project. Keligrout Polyester Resin was used to secure the threaded stainless steel anchors into the concrete. |

The existing rails and attachments were completely rusted out due to the highly corrosive conditions at the sediment tanks. Additionally the original hardware was only galvanized steel and the replacement hardware is all ASTM 316 stainless steel.
All the existing hardware and rails were removed from the top of the concrete tank walls, the old anchors were core drilled out of the concrete and the holes were cleaned out with compressed air. New stainless anchors installed with Keligrout from quart cans. After 24 hour cure the rail attach plates were bolted down and the rails were attached.
