Frequently Asked Questions

What are the benefits of CastleLite Concrete

One of the many benefits of CastleLite is in the method
in which we manufacture our pavers. We using a single
mold process that enables the color to be integrated
throughout the paver. The color you see on the surface
is the same color throughout the paver. This enhances
the color of the pavers for years to come.

Other paver manufacturers use a “face mix” method of
manufacturing. They make a core paver, using “grey”
concrete in the center of their pavers. Then they coat
their pavers with a “face mix”.


Why should I choose pavers over asphalt or

The ground under asphalt and concrete will move over
time, which causes cracking and displacement.
Concrete pavers are modular and flexible, so it will not
crack over time. If the ground does heave or a utility
needs to be repaired under the pavers, they can be
removed in whole and replaced after the repairs have
been made.


Can pavers be laid over the top of my existing
asphalt or concrete?

Pavers can be laid over existing pavements that are in
good condition. If the pavement shows signs of major
cracking, heaving, or settling, we donʼt recommend
placing pavers over these conditions. We recommend
that you remove the existing pavement, treat the
substrate and construct a new structural section
beneath the concrete pavers.


How do the pavers interlock?

All of CastleLiteʼs concrete pavers are interlocking.
Regardless of which shape, color or laying pattern you
choose, they are ALL interlocking concrete pavers. The
term “interlock” is used to describe the internal friction
imposed by the joint sand between the concrete pavers.
It is this interlocking feature that give concrete pavers
the flexibility and durability to withstand minor and
major movements of the native soils. Maintenance and
repairs (if required) are simplified because no mortar is
used in the installation process.


Are concrete pavers slippery?

No, CastleLite concrete pavers have been tested and
are known to exceed the Caltrans standards for friction
coefficient (skid and slip resistance) for highway
construction. Concrete pavers are also known to
surpass the slip and skid resistance standards
established by the American Disabilities Act.

What type of sand should I use under the concrete

We recommend using a hard, course, angular washed
sand. This is typically referred to as “washed concrete
sand”. This type of sand will drain water well and will
not deteriorate over time. DO NOT use rounded/fine
sands, decomposed granite, stone dust or limestone


What type of sand should I use between my
concrete pavers?

We recommend an angular washed sand with sand
grains between a No. 10 and No. 30 sieve. The use of
angular sand will bind together during the compaction
process. The problem with using a very fine sand is it
will wash out easily and will cause an interlock failure.


Will weeds and grass grow between the paver

If you installed your concrete pavers with the
recommended materials and methods, you will have
created a sterile environment that will not allow weeds
or grass to grow between the pavers. Seeds can blow
into the top of the paver joints and weeds or grass can
start growing in any organic material that has built up in
the joints. In the event that this happens, you can pull
the weeds as normally or apply a weed killer spray.


How can I replace a concrete paver?

One of the major advantages of using concrete pavers,
is the ability to remove individual pavers. To simply
remove an individual paver, you need to remove the
sand from around the paver edges. Using two flat
headed screwdrivers, gently wedge them into the joints
of the pavers and rock the paver back and forth. You
will be able to lift the paver out with the screwdriver.


Where can I buy CastleLite concrete pavers?

You can purchase our concrete pavers at any of our
Factory Direct showrooms or on-line at our website.
