Performance evaluation of patch repairs on historic concrete structures (PEPS): the evolution of conservation repairs on the Historic England Phase II test sites and PEPS Phase II results

Historically, little effort had been made to match patch repairs culturally significant reinforced concrete structures so that they are effective and sustain the aesthetic values of structure. The collaborative research project, Performance Evaluation Patch Repairs on Historic Concrete Structures (PEPS), being undertaken by Getty Conservation Institute (GCI), England (HE) Laboratoire de Recherche des Monuments Historiques (LRMH), seeks address this problem. Through its advice grant-aided projects, has tried achieve like-for-like over last 20 years. ten English sites selected for PEPs Phase II non-destructive testing (NDT) includes some buildings where repair work was carried out. Data site location, specification repair, environmental conditions, test results tentative conclusions from phase is presented in paper. Five will be subject further NDT destructive sampling as part III.
