Installation Instructions

HOLLAND PAVERS

Tamp the subbase using a flat-plate

vibrator. Work in a circular motion compacting

the area twice.

Make a grid work of stakes and guide strings to indicate

the finished height and slope of your patio, then excavate

7-3/8", below these lines. This will provide room for a 4"

subbase, the 1" leveling sand base, and 2-3/8" for the

pavers themselves (Image 5). If the area is hilly, you’ll need

to go back and forth between excavating, leveling and

setting strings to get things right.

Soil conditions vary greatly across the country. If after

digging the necessary depth below your strings, you still

find pockets of loose dirt or black soil, remove it or it will

eventually settle, creating a wavy patio.

When installing pavers as a residential driveway, a

minimum of 8" of base will be required. See local code for

details.

Next, bring in the subbase material. Bring the

area up to a of height 3-3/8" below your guide strings (Image

6). It should be at least 4" deep in all places. The subbase

should extend 8" beyond the actual edge of the patio to

provide room for the edging. It’s possible you’ll need to

build up an area to accommodate your patio. In such cases,

remove the sod and loose soil, then build up the area with

your subbase material. Add subbase in 2-3" lift increments,

compact, and repeat until reaching the desired base level.

Building a 10" to 12" subbase is common; even 20" would

not be unusual.

BASE & EDGING DETAIL

Spread subbase to a depth of 4" over the

entire patio area and 8" beyond. Measure

down from the guide strings to establish a

uniform subbase surface.

Tamping the subbase is an important step when installing

your new paver patio, walkway, or driveway (Image 7). Proper

compaction provides stability to the project by spreading

any load over a greater area of the ground below. If laid and

compacted properly the subbase will help to recompress

the surrounding soil that could have been disturbed while

excavating.
