    So, I have to answer the question myself. Maybe it will help someone.

    You can repair a polygon using the geos::operation::buffer::BufferOp class. E.g.

    geos::geom::Geometry * result = 
                       geos::operation::buffer::BufferOp::bufferOp(polygon, 1.0);

    You can find some more good recipes in the Secrets of the JTS Topology Suite.
