I agree, not for play areas, but I've used them for service areas that you want to look green (i.e. for trucks, emergency vehicles etc.) and since the use is infrequent, the grass tends to do well.

Just a reiteration of what someone else noted in their post. These blocks have a big drawback if they are being used for kid's play surfaces. Their edges are rough and hard and will scrape and bruise. They are unforgiving in that way. Also, if you don't keep grass growing in them, they become mud or dirt holders.

I tried to find the name before sending the e-mail but the
suppliers are
closed today (27th Dec.) I'm not sure when the 'holiday
season' finishes
for them but I'll let you know more info. when I can contact them.
Happy Holidays all!

James--is there a name for that 25% concrete product?  I've

never heard

of it and it sounds perfect for the parking our city,

Denver, requires.

Karen, I'm not sure what decomposed granite is.  In my

part of Canada

(the prairies), we use what we call 'pea gravel' for this


I used it around my own house for 'organic flowing paths' -a good
idea, tends to look like a flowing river bed if the edges

are treated

as such, e.g. rocks, planting beds, etc. in an organic

design.  The

pea gravel is smooth round small pebbles, approx 1/4' to 1/2"
diameter, often river washed granite.  In this part of the world
another material used for paths and parking areas is '1/4" down'(
presumably means the same as your '1/4" minus') limestone.

This is

broken, not rounded, small limestone pebbles that go down

in size to

dust.  This tends to pack and harden after several rains

(unlike pea

gravel which stays loose and contains no dust).  This is a

much harder

surface but could track into the house a little (not a lot)

Re/ your second question:  What is often used here for the

purpose you

describe (a drivable surface that looks like a lawn) is a concrete
block made for that purpose. It is about 25% concrete and

75% voids

that earth & grass can be planted in.  Viewed at an angle you see
primarily grass but it is strong enough for trucks.
Hope this helps

Hello cohousing friends!
Our cohousing group here in Ashland is getting very busy


the landscape plans.  In designing our pedestrian paths,

we would

like to create organically styled (flowing around natural


and human movement, ie. not linear) pathways that would

create areas

for gardening, privacy and play in our common outdoor

space.  Our

landscape architect is suggesting 1/4 minus Decomposed

Granite (DG)

for the pathways.  There is some concerns about this

material and how

well it will work.  Does it tend to track into homes and other
places?  Does it need a lot of repairs to prevent muddy

spots?  Does

anyone have any experiences with this or suggestions for other
materials to consider?
Also, we are looking at ways to make the "driveway" past

the parking

area pervious (rather than paved) so that water can flow

through and

we can have an open grass lawn.  This area needs to be able to
support the weight of the occasional car or fire truck so we are
planning to reinforce it with a material that is being

described as

"egg-crate" below the surface of the grass.  If anyone has any
experience with this type of pervious surfacing or other


we would love to know more about it.
I'd like to wish everyone a very peaceful holiday season

filled with

presence, magical moments & laughter.  Reading the emails

that come

in through this list everyday, I am inspired by who you

all are and

your commitment to community.
Thank you for taking the time to read and respond!
