Interlocking Pavers - Do it Yourself Installation

   
   
1. Determine the depth then dig by hand or hire
    someone to bring a skid-steer in to do the
    digging for you. Remember to check for utilities
    before you dig!

   
3. Lay a 1/2" or 3/4" plastic pipe on top of the
    crushed stone and hold a paver on top of the pipe
    to make sure you are about 1/4" above the
    intended level of the finished patio. The paver
    should be about 1/4" high because they will be
    compacted into the bedding sand.

   
5. Using a metal screed or straight 2x4, slide along
    the pipes to screen the sand smooth. Fill any low
    spots and repeat until the sand is smooth. Do
    NOT compact the sand.

   
7. You can cut pavers with a mallet and cold chisel,
    or with a power saw and metal masonry blade.
    Fiber blades are not recommended as they do not
    last. A saw will yield a cleaner cut surface and may
    fit better.

   
9. Compact the pavers into the bedding sand with a
    plate compactor. If you are using untumbled
    pavers or pavers with a textured surface, it's a
    good idea to install a hard rubber pad on the
    bottom of the compactor to protect the pavers.

   
2. Install 4" of crushed stone and compact
    thoroughly using a plate compactor. The patio
    should have a minimum 2% slope (about 1/4" in 1
    foot) for drainage purposes. For driveways and
    other traffic areas, install two 4" layers of crushed
    stone, compacting each layer to a minimum of
    98% Standard Proctor Density. The compaction can
    be measured by a relatively inexpensive test
    performed by a Geotechnical Engineer.

   
4. Using a coarse sand (NOT mortar sand) as a
    bedding layer, spread the sand between two
    plastic pipes. Make the layer slightly higher than
    the pipes.

   
6. Start against a fixed surface, such as a structure,
    patio, driveway, etc. If you do not adjoin a fixed
    surface, install edge restraint on two sides and
    start in the corner. Install the pavers in the desired
    pattern using the "click and drop" method.
    Holding the paver slightly above the sand, click
    against the other pavers then lower onto the sand.
    If the patio has a significant slope, start at the
    lower edge and work uphill to avoid "creep" in the
    pavers.

   
8. When the pavers are laid, install the outside edge
    restraint.

   
10. Spread sand over the top of the pavers, then
      compact again. Repeat the process until you have
      a good fill in the joints.
 

Polymeric joint sand is designed to harden when installed. This will inhibit weed growth and virtually eliminate maintenance. If you decide to use polymeric sand, make sure you have a good fill in the joints, then use a blower on low setting to blow out of the joints to a level about 1/4" below the top of the paver. (When you mist the polymeric sand, a glaze will come off of it. Having the sand slightly below the surface of the pavers will ensure that the glaze does not adhere to the pavers.) Mist the pavers with a hose. Wait until the edges of the pavers start to dry, then repeat. Repeat 3 or 4 times. Polymeric sand MUST be installed on a dry day. Check the weather and make sure there is no rain forecasted for 24 hours.

You can use a paver sealer to protect the paver surface and bring out the color. It will have a slightly "wet" look and will be a little darker. Keep in mind, however, that sealers wear off over time in the higher traffic areas. Once you use a sealer, then every few years you may need to recoat.
