Seems to use some sort of bonding agent flowed over compacted
aggregate material of your choice to create a solidified block
or layer that is completely permeable

Found this on the web:

===============
CELL-TEK GEOSYNTHETICS, LLC

Technical Data: Gravel-Lok Hydrophobic Polyurethane System

Description: Gravel-Lok is a moderate viscosity, single component,
moisture curing liquid designed to stabilize aggregates for foot traffic
and light vehicular traffic. It is ADA compliant for wheelchair access.

Application: Pour or pump onto stones to be stabilized. Do not spray
(atomize). Allow 24 hours to cure. If rain is expected, the area should
be covered with a plastic tarp. Application is not suggested if the
temperature falls below 50°F or rises above 90°F. Coverage rates will
vary with soil conditions. Typical coverage is 15 – 20 square feet per
gallon.

Basically what we have here is a rigid hydrophobic polyurethane liquid
that cures when exposed to air (ie - water vapor). *There are many
polyurethanes that do this (PL-Premium construction adhesive is one
example).

I would imaging that the average high-performance home handiman could
obtain a similar material from a construction supply shop that may not
be marketed exactly for the same purpose, such as this:

Or for the limey's around he

============http://www.elichem.co.uk/p-14-aggregate-gravel-bonding-resin.aspx

EL151SB/NC Aggregate Bonding Resin is a clear polyurethane resin
specifically formulated for use as an aggregate- bonding material for
driveways and paths. *The resin is mixed with aggregate particles and
spread into place where it sets to a durable, flexible surface.

What could be easier?

Buy a load of small stone. *Have it delivered to your home (most places
that sell decorative or landscaping products will do this). *Maybe a few
different types or colors. *Several cubic yards of material. *Small
stone, pea-gravel, etc.

Prepare the area where you want to form your hard-surface pad. *Set some
dividers into it (straight, curved, etc) if you want to form patterns in
the finished surface. *Spread the stone over the area, compact and
smooth it so it's flat.

Buy one (or more) 5-gallon pails of polyurethane resin, spread over the
stone using a large watering can (or devise your own pouring system) and
wait a day or two and it's ready to use.

I really don't think there's any need to go to elaborate lengths to
prepare the sub-surface if you're not going to be driving any vehicles
over this area.

Duh - is the final surface going to be a glossy, flat resin? Through
which one can see the pebbles? A little confused...
