Baumhaus.Bau11 Jun 2017 17:34Hello everyone,
We are now starting to work on our outdoor areas. Curbstones have been installed, and now we need to choose a drainage channel between the street and our garage driveway.
The street is covered with asphalt, and on the other side, paving stones will be laid. As a placeholder, we have placed a timber beam in the trench where the drainage channel will be installed later.
My question is whether it is sufficient to use a plastic channel (about 10€/m (3.05 USD/ft)), or if it would be better to choose a concrete channel (C40/50), which is only slightly more expensive.
The channel will be driven over several times a day, including by older American cars that tend to weigh more than the typical plastic-bodied vehicles...
I understand that the grate on top of the channel also matters, and we will probably opt for a more robust one.
If anyone has experience with this, I would be happy to hear your insights.

Knallkörper11 Jun 2017 19:41I can only recommend using a concrete channel and setting it in concrete. Cast iron is best for the grate.
In the old house, we had a cheap plastic channel in an asphalt driveway, which became brittle and fell apart over the years, even though I only drive a 2-ton (approximately 4,400 lbs) plastic car.

I also tend to prefer concrete rather than plastic.
What about polymer concrete? Is its strength comparable to regular concrete?

Knallkörper12 Jun 2017 09:39Yes, polymer concrete is actually a type of real concrete. I believe it handles tensile stresses better than cement concrete, and it is waterproof as well as frost-resistant, so it is basically the ideal material.
Instead of cement, EP, PUR, or polyester resin is used as the binder. All three plastics are highly UV resistant and weatherproof. Polyester is the least moisture resistant of the three. However, entire ships are built from it, so porous is something else. They are solid, lighter, less impact resistant, but more flexible in bending. But who hits something like a channel hard anyway? So impact resistance is not that important here.
