Installing
Edge Restraint
Before installing your edge restraint you need to figure out your end line for
the patio and a center reference line.
To draw the end line, we measure out from the house the length of the patio on
both sides. Then we snap a chalk line between the two marks to give us the bottom
of the patio.
Now we need to draw a line perpendicular to this end line. Here's one way to do
this
- Find
the center point of the end line.
- Mark
off an equal length in both directions.
- Using
two tape measures, start at the two outside points and cross the two tape measures.
- Pivot
the tape measures until they cross at the same measurement.
- Snap
a chalkline from the center mark to the point where the tapes crossed.
- Mark
the ends of this perpendicular line on the edge restraint and the house so you
can resnap them when they get covered up with sand.
For our paver project, we used a PVC edge restraint that's designed specifically
for interlocking pavers.
We joined the sections with a connector pipe, and used 10-inch spikes to hold
the edging in place.
Sometimes it works best to put in all the edging right away. In our project, we
just installed the edging for the end at this point.
Sand
Layer
We used about two cubic yards of sand to make a one-inch bedding layer over the
whole patio. You need special sand for your bedding layer; ours was coarse washed
concrete sand.
We lined up one-inch thick pipes to give us our 1-inch layer. We filled sand in
between the pipes, then screeded it off level with the tops of the pipes. In
places where you can't use a screed, it's okay to use a trowel to smooth it out.
Setting
the Pavers
Resnap your center perpendicular line before starting the pavers..
We set our pavers in two sections: the big patio area first, and then the sidewalk
area. We started at the far end and worked our way up toward the house.
We've got a row of red pavers in what's called a "soldier course" along the outside
edge of the patio. So those were the first ones we set in.
We started the first two on either side of the line and worked out from there.
You
just set the pavers gently into the sand. Don't slide them in from the side, don't
twist them, don't push them down.
Our
general pattern is to set the pavers in sort of a pyramid, centered on our reference
chalkline. Adjust the pavers every few to keep them straight.
There are several different tools you can use to cut pavers. The most common is
a mechanical splitter. However, a splitter leaves a slightly uneven cut.
To get a cleaner cut, you need to use a heavy duty power miter saw. The pros use
a wet saw that's washed with water to keep the heat and dust down.
The main part of our patio was a herringbone pattern.
After the pavers were set, we put the edging on the sides. If we had installed
the edging earlier, we would probably have had to cut all the pavers on the sides
to fit.
Tamping
the Pavers
Now
run the compactor over the pavers. This starts the process of locking everything
in place. The compactor is pressing the pavers down, evening out the tops of the
pavers, and forcing some of the sand up into joints from underneath.
Next
you fill the joints with sand from above. And this is what makes a patio incredibly
strong.
You should be able to use the same type of coarse washed concrete sand as you
did for the bedding layer. However, you need the sand to be pretty dry.
The process is to spread sand with a broom, run the compactor over the pavers,
spread some more sand, compact, and so on, until the joints are filled. This process
will make for a very solid paver surface.
After your paver project is complete you have the option to seal the pavers. Sealing
will bring out the colors of the pavers and protect them from stain, but you will
have to reseal them every few years.
