STACK STONE

The Stack Stone system was created with the Do-It- Yourself landscaper in mind. Each unit has two, textured, natural looking faces; a larger 4" by 8" face and a smaller 4" by 6" face.

CORNER

The comer unit needs to be split in half with a hammer and chisel. Place the chisel in the splitting grove on the bottom of the unit and split the unit into a left and a right half. Place one half on the first course, and the other half on the next course. Use adhesive to secure the units together. If corner units are not required, the unit may be used as a coping stone.

SOLID WALL

To construct a solid wall, the larger faces of adjacent units should be aligned on opposite sides of the wall. This creates a straight wall with a continuous stone face on both sides.

Semi-Solid Wall

A semi-solid wall is constructed by aligning the larger faces of all units on one side of the wall. The side of the wall with the larger faces will exhibit a continuous surface. A semi-solid wall is necessary for curved walls. It can also be used for straight walls.

CURVES

The minimum radius for a curve is 21" for inside curves, and 29" for outside curves. For inside curves either the larger or smaller face can be used for the face of the wall. For outside curves, only the largest face can be used for the face of the wall.

COPING UNIT

The coping unit, which is the finishing course of units, should be secured to the top of the wall with an adhesive. A line of adhesive should run along the length of the wall on either side of the tongue of the units below. A coping unit may replace a standard unit anywhere within the wall as long as it is not placed above or beside any other coping unit.

Curve Transition

When the alignment of the wall changes from an outside curve to an inside curve, it will be necessary to place transition pieces on every other course. This transitions is made using two left or right corner unites.

Free Standing Wall

If the wall is to be constructed so there is no soil within 8" of the top, the wall is considered to be free standing. For the free standing wall, it is recommended to place adhesive under the top two courses of the wall.
