we have a deigner who has specified grasscrete on a school car-park area. i can see a few H&S issues with this: high heels getting stuck, mud on clothes, people tripping etc.

have any other users used such a system and if so what did they do to overcome the risks associated?

thanks

the designer should be addressing issues on what they specify

This has environmental benefits and may be part of a Sustainable Drainage Scheme.

Heels are a problem only for the wearer.

Smiff, i realise heela are only an issue for the wearer. it is part of the planning requirements that the area be grasscreted, should they then not have looked at the risks associated with the requirement?

surely for the grass crete to beneficial the holes need to be of a certain size, thus making them dangerous for people wearing heels?

In my view grasscrete offers environmental benefits over a paved surface and a pure grass surface. Sensible risk assessment (IMHO) discounts risks from people wearing high heels, but what you should do is make sure that the area is well maintained. There can be problems if the grass does not germinate leading to bare patches, and possibly settlement or erosion of soil that leaves trip hazards. If properly constructed it should have very good drainage.

We have grasscrete parking area and have never had any problems. I've not tried it with high heels on myself but have observed others. With good drainage the soil stays surprisingly firm.

I personally believe that the flood-reduction and aesthetic benefits of this type of paving outweigh the trivial risk to those who choose to wear a particular type of shoe. Where I live and work the footpaths are grass, mud or rock. Just as God intended. I would not have it any other way and dress accordingly. I choose therefore to only wear heels in the privacy and safety of my own home. The carpark of my local town has this type of paving and it seems to work very well, especially as it is on the flood plain. Sorry if my thoughts have touched a nerve, but I happen to believe that we are over-paving our green and pleasant land (hence the flooding that does nobody's H&S any good), and the proposed solution makes the best of a bad job.

Strange logic smiff, and a strange statement - if God intended it.

Luckily my house is built of brick/slate and not mud. What's yours?

What is so strange, that I agree with Martin above, that I live in the country, that I understand the benefits of minimising hardcover in development, or the cross-dressing joke?

Not being familiar with the product I did a little investigating. According to the supplier this stuff gives you bow legs and a very hairy body. See this link: http://www.grasscrete.com/img/circle/7.jpg

My employer has numerous schools which have limited provision for parking and would benefit from being able to adapt and use parts of their lawned areas for extra parking. Rather than use tarmac which would add to environmental problems by causing rainwater to run directly to drains, from time to time I have suggested using grass-crete type surfaces which allow rainwater to soak into the ground beneath. I think plastic mesh versions are available as well as concrete ones.

Please can anyone advise whether such surfaces are significantly cheaper to lay than tarmac, including the appropriate supporting foundation layer in eah case? If you can give a rough idea of the approximate cost per square metre compared with that for tarmac, that would be even more helpful.

Also, does anyone know if the laying of grass-crete or similar surfaces is within the capability of willing volunteers with appropriate information and supervision? If not, I guess the cost of using a contractor to provide additional parking surfaces will be the dominant factor no matter what sort of surface is being laid.

To end on a frivolous note, an earlier responder referred to sensible risk assessment (IMHO). Seeing repeated mentions of IMHO in/on this forum prompts me to ask: Is IMHO related to IMO, IMSO, IISO or even NAMHO?! Is it a secret select society for H&S people with membership by invitation only? Alternatively, could it be one of the Latin words which a few local councils have recently told their employees to desist from using in official correspondence?

so the general opinion is if a person chooses to wear heels and then gets stuck in the mud, falls over a breaks her/his ankle its tough??? the benifit to the environment far outweighs the detrimental effects to ones ankles??

and that is the result of a risk assessment?

if only the rest of the world were so black and white!

I know it isn't the U.K. but the Dusseldorf exhibition centre had this type of surface for visitor parking for years and I do not think that it was ever a problem. Of course, there is one question that hasn't yet been touched on - maintenance! You have to cut the grass!

NJS,

Yes it is sensible risk assessment! My earlier posting said that in my experience there was little evidence that the surface would cause a high level of risk whatever footware was worn. Consequently whilst the potential severity is (at max) a broken ankle the likelihood is slim. In my mind this is an acceptable risk.

A perfectly smooth tarmac surface may be safer, but is far more expensive, has environmental implications - and at this time of year needs gritting.

There is a volenti element to choosing high heels that cannot be ignored and has been discussed on this forum before. I believe that people who wear high heels are aware of the risks and limitations and will tread carefully. I do the same when I am wearing patent leather soles compared to when I'm wearing work boots.

I do not believe that grasscrete significantly alters the risk compared to alternative surfaces.

The key element to reduce your liability (if that is the main concern) is to ensure that that the area is maintained. Simply: You can't be sued for having grasscrete (or any particular surface, or steps, etc), but you can if you fail to maintain it.

Really. A risk assessment for grass?

In the absence of a response I thought I would clarify my comment of 'show me where it says you can't be sued'.

If a surface or steps etc has, for example, a design defect then a person attributing an injury to the defect would be quite within their rights to sue.
