This article shows the principle requirements for remediation of WTG foundations and the advantages and disadvantages of different injection materials like cement lime, epoxy resin and PUR resin. Mostly there are reservations against epoxy resin mainly because of assuming wet cracks in foundations. Regarding state of the art epoxy resins are not usable at wet surfaces or for cracks with liquid water inside. It will be shown that nevertheless it can work and why it works. There were done some basic investigations in how to fill a crack/gap between two concrete slabs. The gap was filled with water or a suspension to simulate a wet crack surface. The spread of an Epoxy resin in the gap was investigated.
