Koster Aquatecnic offer a comprehensive range of materials in order to provide the optimal solution for every waterproofing challenge, whether new buildings have to be waterproofed or old buildings have to be restored.
Our high quality and long lasting waterproofing systems sustainably increase the life cycle of buildings. Avoiding moisture damage makes less repair work necessary and reduces the energy consumption because the insulation stays intact. Koster concrete repair & resin injection systems protect concrete from corrosions by acids or other chemical attacks and help to repair already corroded concrete in the most economical and safe manner.
With over 40 years combined worldwide technical knowledge in the UK office and extensive technical and scientific support from Germany, the user friendliness of our Waterproofing Systems in combination with the high level of certainty regarding their effectiveness were the reason for their development.
We provide an in-depth technical consultancy service and will recommend the best solution to suit the buildings requirements. For existing buildings it is vital that the correct diagnosis of problems and potential future issues are highlighted and reported so that client confidence is ensured.
