DETAILS | Interlocking Planters
Interlocking planters add
beauty and charm to residential and
commercial landscapes.
The flexibility of Keystone Potenzo Stone gives you the ability to create a wide variety of impressive projects. One particularly rewarding design option is the interlocking planter system. If built correctly, this straightforward project will produce a unique design element that is as sturdy as it is impressive.
In wall designs with 90° corners, it is recommended that the largest unit size available be used at the corners, overlapped and interlocked with the units above and below. In addition to providing better stability through greater mass, the large units provide an additional pin position for greater design flexibility. Interlocking planters should be constructed as one cohesive structure, not multiple
independent planters.
Where planter walls intersect, care should be taken to overlap and interlock the units- not just “butting” the walls up against each other. It is also recommended that planter walls be assembled in the “closed” position (without any gaps along the inside of the wall) when possible.
To insure proper drainage, stability and appearance, each course needs to be backfilled as the wall progresses. Free draining fill material that compacts well (i.e. 1/2"-3/4" crushed stone) should be placed to a depth of 12" behind wall. (Good drainage will help eliminate the undesirable “wet” look at the front of the planter.)
