Different Methods of Laying Arches
There are several ways to build a stone arch. Each method has advantages and potential pitfalls, but choosing the right one for you can make stone bridge building easier.
Building Rubble Arches
Stone arches made with rubble masonry are easy to construct, and can be quite strong. The key to successfully building a rubble arch is in the laying and shimming of the stones.
The Strength of a Mortarless Stone Bridge
A mortarless stone arch bridge can be quite strong, as the secret to a successful stone bridge is to keep all the forces in compression as opposed to “gluing” the stones with mortar.
Using Feathers and Wedges to Split Stone
Feathers and wedges are simple-to-use and reliable tools that provide an easy means for obtaining reasonable slabs out of massive, irregularly shaped stones.
Building With Stone: The Intermediate Stage
Often at some point a masonry project will start looking wrong in the middle of construction. However, it is important to keep building with the final goal in mind.
Mortared Vs. Mortarless Masonry
In this post we contrast the pros and cons of mortared and mortarless stone arch bridge construction, mentioning potential pitfalls with each.
On Mortar
In this post, we investigate the advantages of using mortar in stonework, looking into what purpose the mortar serves and its limitations.
The Importance of Friction
Friction is a crucial factor in stone arch bridge stability, and, when the line of thrust is solidly within the arch, holds the arch stones firmly in place.
