Masterful sealing

Building structure sealing and crack grouting

DMI can provide you with an all-in-one package when it comes to sealing structures that come into contact with water. Our staff and the specialists from our subsidiary, DBS Spezialsanierungen GmbH, can carry out any concrete restoration that may be necessary after sealing. We offer our customers service from a single source without any overlap.

For friction-locked grouting work, we use EP resins, rigid PU resins or microfine cements. For sealing injection work, we opt for flexible PU resins or acrylate gels.
