Hi All,

Bit of a strange question this but I have a problem that needs a solution ASAP.

I'm designing a car park drainage system for a local council as part of a design and build high school project. The site has some unusual characteristics which means we can't put pipes in the ground in the car park so we were considering using Kerb Drains i.e. such as those found here: http://66.232.135.138/drainage/detail_beany_block.htm

There is also another major problem.

We need to get the water across the school access road. Normally we could put a pipe under the road with a minimum cover depth of 1.2m. In this case this isn't feasible and we need some way of getting the water across the road at a much shallower depth than this, but obviously we can't have it flowing across the surface of the road!

I was considering using some of these (from Aco Drains):

The idea been to have them crossing the road at ground level so they act as a channel across the road. Does anyone know if this would be feasible or what any potential problems would be? E.g. blockage, flooding, damage due to traffic loads etc.

Also, if anyone knows of any other viable approach then it would be very much appreciated if you could let me know what it is!

Thanks
-Richard

Aco have a system that can do the lot - the kerb-drain and the road-crossing channel, in one, complementary system.

I'll ask my pet Aco bod to pop in to the Brew Cabin on Monday and point you in the right direction.

Hi Tony,

Thanks for the advice. I've found that Marshalls have a system that will do the whole lot at well (found the link on your web-site to the Beany Block system).

I think these are the kinds of things I'm looking for.

Joe Bordas, Product Manager at ACO, has been trying to get into the Brew Cabin, but it's having another of its dicky fits and won't let him post, so he's asked me to post the following on his behalf....

ACO do offer a design & layout service- if you want to contact the Technical Services team they'll help you to specify what you'll need and should be able to save you money by putting what you need in the right places. They can be contacted on draintechnical AT aco DOT co DOT uk, and their service is completely free.

In short, KerbDrain can go around the edges, and RoadDrain can be used as a channel across the road. Both of these systems are monolithic, so no worries about components coming apart. Also they're made of polymer concrete (not OPC concrete) so are far lighter for the same strength. You may find that RoadDrain is in fact overspec on size and strength- a similar system, ParkDrain, is ideal for car parks (hence the name) and offers greater capacity for the installed height. For exact sizings, run lengths and so on, get in touch, and let ACO take the strain!"

Many thanks,

Ah "Park Drain", that name takes me back to my yoof when I used to go fishing. We'd cycle past the Park Drain hotel to get to the appropriately named Idle Stop.

To digress even further - the Park Drain hotel was built when coal was found under the area, and a speculator thought the area would soon be full of coal mines. Unfortunately that never happened, and this grandiose hotel stood in the middle of open fields and drains. There, we've got back on to topic at last!
