A general guide is presented to the materials and methods that are generally used in repair work. The properties are briefly reviewed of ordinary or rapid-hardening Portland which is the cheapest basic material; epoxide resin, the properties of which can be adjusted over a wide range by varying the formulation; polyester resins (cheaper than epoxide resins); natural and synthetic rubber latices which are used in conjunction with cement (as bonding agents or in order to modify the properties of cement mortar or concrete); and polyvinyl acetate (PVA) which is used for purposes similar to those of rubber latex. A review of repairs to spalled concrete describes the preparation for the repair, the cement-based repairs, and resin-based repairs. Methods of sealing cracks are outlined for conditions when further movement is not expected and when futher movement is expected. Gunite is described (which is a general term for spray-applied concrete and known in the U.S. as 'Shotcrete') as well as guniting. Waterproofing problems are reviewed, and attention is focused on concentrated leaks and damp areas.
