US Patent 7537413 Adjustable manhole cover apparatus

An adjustable manhole cover apparatus designed to fill a gap of any size or shape between a manhole and a resurfaced road pavement. The preferred embodiment provides a plastic bag filled with cement or heavy foam to fill the gap and an aluminum lid. The plastic bag prevents the filling from sticking to the pavement and manhole, while being heavy enough to support vehicles passing over the filling. Accordion-shaped versions provide accordion-shaped forms, with one incorporating a manhole cover, to be filled to eliminate the gap between a manhole cover and pavement.
