Split faced or Bull nosed squared un-coursed rubble – common from the mid 19th Century after the introduction of frame saws and splitters, joint widths, generally 8-12mm on bed, slightly wider on the face to 12-20mm. Sands usually fine sand  with occasional pieces of 4-5mm maximum aggregate size normally less than 2-3% of the total sand grading.  (See section on choosing sands)

Typical construction and finishing mortars were the same until the early part of the 20th Century when the rapidly expanding variety of cement gauged lime mortars were commonly used for joint finishing, either as a wet on wet process or as joint finishing at a later date, It became common practice, particularly in urbane areas to apply a stronger mortar over the common lime bedding mortars.

Some joints were very slightly completed with a tight cement fine sand finish – tooled tight – sometimes with a false joint struck through the centre of the joint with abundant surviving examples being only 3-5mm thick – in most instances, these were “Ironed on” wet on wet with the construction mortar.

This became a much more common practice from the Edwardian period onwards as transportation links increased the availability of cement proportionality with the rapid increase of poured in place concrete foundations.

Many large public buildings, bath houses, libraries, town halls etc used this type of masonry, along with large scale urbane development, where dressed masonry around windows and doors was infilled with uncorked and coursed stone of a similar dressing style, As the rapid increase in cities and suburbs increased, the strain on the quarry supply side and the emergence of cast block, often meant the front of the building was of stone and the remainder was rendered or roughcast.
