Installation Guidelines: Cambridge MaytRx^® Column
Columns that are larger than the standard 20 inch by 20 inch MaytRx column can be built as shown by this 36 inch by 36 inch column. Cutting of some MaytRx stones may be required to develop a perfect fit. Each layer’s construction should start at the four corners of these larger columns by using a split A, B or Y part and building away from the corner. To complete each layer, full MaytRx or cut MaytRx stones are then set between the corner stones to finish each side of each layer. Paver grade adhesive is advised in the construction of all columns. Columns may be square as shown or rectangular as required by the job.

Maytrx Column Basics
The multi-stone MaytRx system can build impressive 20 inch square columns and posts. The following drawings show three groupings of MaytRx stones to make 1/2 of a column layer. (i.e. 10 inches by 20 inches)

Combining any two of these three groupings will make one layer of a MaytRx column or post, as shown below.

Rotating layers 90 degrees gives a crossing of the seams of the MaytRx stones for interlock and stability.

Any combination of the 10 inch by 20 inch segments can be used for various layers as a column or post is built. The 90 degree rotation and random use of the three segments will give the four sides of the column or post a random pattern of various stone sizes. Be certain that the column or post is built on a concrete or highly compacted aggregate below grade footing that will hold the column or post plumb for years. Keeping at least 1/2 stone, 3 inches, below grade for the first layer is a proper installation

By adding an additional dimension of stone on each side, the column will increase from 20'' by that dimension and allow a hollow center for wires.
