A stone staircase was cut to the southern counterfort plus a room large enough for a team of six men.

The meaning of the word Sankamphaeng in the Thai language is fortification or counterfort.

The counterfort with the staircase was roofed with wooden boards and tin sheets in 1869.

A counterfort could be constructed; that is, a new wall about 20 feet behind the existing wall, with perpendicular buttresses between them.

Sometimes cantilevered walls are buttressed on the front, or include a counterfort on the back, to improve their stability against high loads.

The term counterfort can be synonymous with buttress, and is often used when referring to dams, retaining walls and other structures holding back earth.

Bohemund's troops built a counterfort outside Saint Paul's Gate in Antioch's northeast wall to protect themselves against missiles from Antioch's defenders.

Its masonry is very uneven, including several stone pillars that have been inserted into it, often not fully, and its counterfort is made of small, irregularly fitted stones.
