Installation Guidelines: Cambridge MaytRx^® Wall Systems

The Cambridge MaytRx® Wall System consists of four unique basic wall stones and a cap. The four double-sided shapes (designated A, B, X and Y) offer a total of five different face sizes and can be used to build freestanding walls and landscape retaining walls that are up to three feet high. With the use of MaytRx® pins and geogrid, higher engineered walls of any height or length can be accomplished as well.

Constructing A Freestanding Wall

The four Cambridge MaytRx® stones (A, B, X, and Y) can be used to build a freestanding wall with a solid face on both sides. By randomly placing the five face sizes available on the four stones, finished walls will have an attractive free style appearance. Another variation may be added by placing capstones on end as a soldier that spans two layers (12") of the wall. With the capstone protruding 1/2" off the face of the wall, this design approach will provide a break in the random pattern while adding a 3D effect.

Stones are easily placed using the alignment groove that visually matches up the next stone in line. Freestanding projects can be built on compacted aggregate or a poured concrete footing. It is important to make sure that the wall is plumb. The wall can be strengthened further by adopting a serpentine design or by incorporating 90-degree corners or columns. Complete the installation with capstones.

Constructing A Landscape Retaining Wall

When installing a landscape retaining wall, excavate a trench approximately 16 inches wide. Walls of 3 feet in height require a trench depth of at least 6 inches and at least 3 inches of compacted quarry process. Three feet is the maximum recommended height. Dig to virgin soil or compact the soil below your footing to high density. Next compact and level your footing material. Place the first course of Cambridge MaytRx® stones smooth side down. Use a carpenter’s level in all directions and a string line to verify straightness. Use the side alignment groove and line up additional courses to achieve a 3/4" setback, staggering the face seems for interlocking wall strength. Compact a backfill of 3/4-inch stone behind wall. Complete the installation with capstones.

Constructing Engineered SRW Walls

With the use of MaytRx® pins and geogrid, engineered walls may be built up to any height or length with the proper-engineered design.
