Ashlar Masonry Techniques

Ashlar Masonry

• Ashlar masonry uses large rectangular blocks of stone, specifically sculpted to have square edges and even faces.
• Requires dressing the stone, making it a costly option.
• Different types of ashlar masonry exist, categorized by stone surface treatments.
• Ashlar Fine Tooled uses stones of the same height, meticulously dressed on all sides, resulting in uniform mortar thickness.
  • This method demands considerable labor and material wastage during dressing, making it expensive.
  • Offers excellent bond in the masonry.
• Ashlar Rough Tooled uses roughly dressed stones, creating uniform joints no thicker than 6mm.
• Ashlar Rock, Rustic, or Quarry Faced resembles rough tooled, but leaves a rough, chiseled margin on the face.
• Ashlar Chamfered is similar to quarry faced, with the edges beveled at 45 degrees for a depth of at least 2.5 cm.
• Ashlar Block in Course utilizes squared, dressed stones, bridging the gap between rubble and ashlar.
  • Resembles Coursed Rubble Masonry or Rough Tooled Ashlar Masonry.
• Ashlar Facing is the most refined type of ashlar masonry, used sparingly in expensive projects.
  • Its high cost makes it unsuitable for full wall thickness, leading to facing built in ashlar and the rest in rubble to reduce costs.

Rubble Masonry

• Rubble refers to stone, irregular in form and size, used in masonry.
• Rubble masonry is characterized by randomly placed, undressed stones, often found in rustic buildings or traditional structures.
• Examples of rubble masonry include random rubble, coursed rubble, and dry rubble masonry.
• The quality and stability of rubble masonry are primarily determined by the size and shape of the stones, the mortar used, and the craftsmanship involved.
• Due to its varied appearances and rustic character, rubble masonry is often aesthetically appealing and adds a sense of authenticity to buildings, making it popular in restoration and preservation projects.
