GRAVEL BASE

A properly constructed graded aggregate base is a minimum requirement for placement of your unit.

The sketches below show the minimum excavation area for different unit assemblies in a stand-

alone configuration; note that the excavation area extends one foot beyond the actual footprint of the

unit assembly on all sides. When a patio is included, the perimeter of the excavation would extend

one foot beyond the entire installation. Excavate 16 inches below the proposed base of the unit. When

a patio is included, the same excavation depth should be used for the entire area; the bottom of the

bedding layer for the paver should match the bottom of the base for the Elements

After the area for the unit is excavated, make sure the soils exposed are stable enough for support

of the Elements

structure. The graded aggregate base material should not be placed directly on

™

topsoil or other organic soils. If the exposed soils are too soft to work with, the excavation depth

may need to be extended or an alternative foundation support system may be necessary. Level

and compact the exposed excavation base until it is firm and unyielding. Once the excavation is

level and compacted, backfill the excavation with the graded aggregate base. The base material

should be placed in no more than four inch loose thickness lifts and compacted until it is firm

and unyielding. Repeat with subsequent lifts until the base elevation is achieved. It is important to

ensure that the graded aggregate base for the unit is level front to back and side to side while the

patio area should be graded to slope away from the unit.

Be sure to follow all local building codes before and during construction.
