Works completed within the waiting room of Welwyn Train Station. Kenwood worked in conjunction with other railway contractors to complete this project. Plaster was removed prior to our arrival; our operatives then worked over the weekend to inject a chemical damp proof course. They then applied a tanking system to the base of the wall; this prevents lateral dampness while the damp proof course prevents rising damp. Now our works have been completed the treated walls are ready for the waiting room to reopen to the public.
