CONCRETE PATCHING GUIDE

Maintenance personnel often select a material for patching concrete based on what they have used in the past. However, each patching job has particular demands, which may be different from what was required in past applications. Also, the list of available products changes often with manufacturers producing new patching materials, discontinuing some products and changing the name of products. The Oregon Department of Transportation recognized the difficulty in selecting the right patching material and developed a patching guide to help maintenance personnel determine which product to use. The selection tool is based on a Microsoft Excel spreadsheet and matches the attributes of specific products to the needs of a particular patching job. An output report is then generated and provides a list of qualified and conditional products from the Qualified Products List.
