How are outfalls/gullies constructed?
Drainage gully outfalls can be accommodated in a wide variety of asphalt kerb details. Wherever possible it is desirable to provide insitu machine formed kerb around the grate whether the grate be located on or off the kerb line. Pre-laid kerb may also be used to form off line mitred outfall details. The kerb is affixed to the apron surround using Bitukold. Additional gangs may be supplied to ensure that the benefits brought about by the high speed application of machine produced is not lost by the reduced output of the more labour intensive production of hand formed outfall details.
