Landscape Pavers Installation
When installing your edge restraint, it should rest directly
on top of the compacted gravel base. The compacted gravel base course should
extend a minimum of 6in beyond the perimeter of the pavers. This will provide a
proper foundation upon which the edging restraint can sit. Manufactured edging
( i.E. Plastic, steel or aluminum ) should be firmly anchored into the
compacted gravel base( check with the manufacturer's literature for the
recommended spacing of the spikes). There are some edging restraints that will
extend deeper into the gravel base or beyond the base course ( i.E. Timbers or
poured-in-place curbs ). Edging restraints should never be placed directly on
top of the bedding sand. This could result in the migration of the bedding sand
and eventual lateral movement of the pavers. If there is a possibility of
losing bedding sand between the pavers and the edge restraint, then geo textile
fabric is recommended. When a gap between the pavers and the edging exceeds 3/8"
(10mm), then the space should be filled with cut pavers. All edging
applications should be properly back filled after they are installed to help
provide additional stability.landscape pavers is an excellent resource for this.
After installation, the pavers need to be compacted. The
entire area that is to be compacted should be swept clean of any foreign
objects and debris that can cause scratching or scuffing on the surface of the
pavers.
It is important to have a compactor that can exert between
3000lbs. And 5000 lbs. Of centrifugal compaction force. In addition, it is
important that the first compaction takes place before any jointing sand has
been applied to the pavers. If jointing sand is applied to the pavers before
compaction takes place, this can cause a bridging problem and will not allow
the joints to be completely filled with jointing sand. This can also prevent
the pavers from being properly set into the bedding sand.
When compacting the pavers, it is recommended that you make
at least two passes in different directions across the pavers. This will allow
the pavers to be properly set in the bedding sand and will force the bedding
sand up into the joints from the bottom of the pavers. The compaction of the
pavers is very critical to the final performance of the pavers. Failure to do
proper compaction can result in deformations and pavement failure over time.
