What Is Rubble Stone Masonry?

The science of rubble stone masonry is based on the use of natural and quarried stones to build walls, retaining walls, columns, arches and vaults.

The stones are first sorted by size and shape and then laid in courses with the smaller stones at the top and the largest stones at the bottom.

The stones are bonded together with mortar, which is a mixture of lime and sand. The skill of the mason is to use the stones to create a strong and stable structure.

Historically, rubble stone masonry was used to build castles, churches and other large public buildings.

The walls were made thick to withstand attack and the masons used a variety of stone shapes and sizes to create a decorative effect.

Today, rubble stone masonry is still used for a variety of applications, including houses, walls, garages and outbuildings.

What Are The Types Of Rubble Stone Masonry?

Rubble masonry is a type of stone construction where the stones used are either undressed or partially dressed.

There are two types of rubble masonry: random rubble masonry and squared rubble masonry.

Random rubble masonry is constructed using stones in a random order. There are two subtypes of random rubble masonry: uncoursed random rubble masonry and built-to-courses random rubble masonry.

Uncoursed random rubble masonry is the roughest and cheapest form of stone-walling. Stones are of widely different sizes, and greater care and integrity is needed in arranging them to distribute pressure and avoid long continuous vertical joints.

Built-to-courses random rubble masonry is similar, but the work is roughly leveled up to form courses.

Squared rubble masonry is a type of rubble masonry in which face stones are squared on all joints and beds by dressing before laying.

There are three types of square rubble masonry: uncoursed square rubble masonry, square rubble built to courses, and square rubble regular coursed.

UnCoursed Square Rubble Masonry uses stones with straight edges and sides, arranged in irregular patterns.

Square rubble built to courses uses the same stones but is leveled up to courses of varying depth.

Square rubble regular coursed is a superior variety of rubble masonry where the stones are squared on all joints and beds, laid in courses of equal layers, and joints are uniform.

What Is Ashlar Masonry And Rubble Masonry?

Masonry is a construction trade that involves the use of stone, brick, concrete block, or glass block, fitted together with mortar to build or repair walls, arches, vaults, and other structures.

There are two main types of masonry construction: ashlar and rubble. Ashlar masonry is characterized by the use of blocks of even size and shape, with minimal or no mortar between them.

The blocks are usually dressed (sawn or chiseled) to create a smooth, uniform surface. Rubble masonry, on the other hand, involves the use of irregularly shaped stones, with lots of mortar between them.

This type of construction is often used in areas where good quality ashlar stone is not available.
