Hi Tufty
I am rather late to the party with this one.
My father also served in the Airfield Construction Branch and was with 5202 Plant squadron during the Normandy Campaign.
He was also wounded, by shrapnel, and briefly hospitalised at No8 RAF General Hospital. The hospital was located in Brussels in early 1945. I believe the injuries may have been sustained as a result of enemy action as part of Operation Bodenplatte. A number of airfields were attacked on 1 January 1045, including Ghent.
I believe 5202 Squadron was at Ghent, St Denis Westrem Airfield, at the time of Bodenplatte.
