Permeable Pavers have changed a lot in the last 10 years. They were able to make the joints a lot smaller. Reason they invested to changed the joints was Ladies' heels would fall in the cracks. That was why permeable were mostly turned down! Driving over newer permeable pavers is not noisy now.
I see...So we got rid of cobble stone roads, to put in asphalt and concrete roads, to now get rid of the impermeable urbanite, to install cobble stone roads. With french drains! The idea in general is sound, and this video is beautiful. I worry about uplift during mass rain events or subsidence in areas creating uneven patches. I also worry about it's frictional stability when overlaying clays. Lastly, if anyone has every driven over cobble stone or brick roads, they know it's incredibly noisy.
I agree that the idea is brilliant in general, but i think its use and location needs context. Shouldnt be near buildlings for one and not on heavily trafficked roads. Therefore carparks really are one othe best situations to use it in. When you think at the number of carparks around, this would do a decent job at minimising runoff and pollution so i think it should have a place in development.
Wouldn't there be problems with the underlying soil eroding out from beneath the road surface over time in some environments? Also, the soil beneath roads is going to be highly compacted, especially if it's clay. How much water infiltration is there realistically going to be?
Hello! Different soil and traffic conditions will result in different construction methods. Depending on the soil’s load bearing capacity, the base thickness will vary in order to ensure adequate conical load distribution. With regards to soil infiltration rates, they too vary greatly. Low infiltration soils, like some clays, will require the use of an exfiltration pipe to direct subsurface water to a soak-away pit, dry-well, drainage swale or other approved option. Thank you!
I would like to ask - since the aggregate allows spaces for water to flow and also doubles as the insulation against freezing, what options exist for places that face regular snow/rainfall that would see near-freezing liquids flow through at high frequency? Also, what elements of this system can be easily replaced? Does the aggregate not complicate pipe maintenance and do we know what occurs in terms of erosion below the system (how far down does this impact the ground stability? Is there any risk of sinkhole cavities forming?) The product lifespan vs traditional and alternative methods? If the aggregate filters debris and dirt - is there not an accumulation of it? Thank you in advance (I'm a student looking at different water management options so any and all factual information is appreciated).
Hello Gabriele! Simple and regular maintenance (sweeping or leaf-blowing) is enough to prevent the accumulation of dirt or debris in the joints that could give seeds or spores a place to germinate or sprout. Ultimately, a well maintained system allows water to flow so easily and quickly through the joints that it is very difficult of plant life to survive. Thank you!
Hello! The insulating factor of the air found in a permeable pavement system greatly reduces the frequency of freezing. However, in the event that water freezes before it is evacuated, the space between reservoir aggregates allows sufficient room to accommodate the expansion caused by freezing water. The system is flexible enough to tolerate minor movements.

Hello, The geotextile serves primarily as a soil separator. We do not want the open-graded stone to blend with the soil, over time. A geotextile with an apparent opening size (AOS) of 70-100 and a grab-tensile strength of 110 lbs will provide enough resistance to separate the materials, confine the base and permit water infilitration. Thank you!
Yup, I get it, but what's the next after the water pass through the geotextile? I mean it will flow the soil or sand away then make a cavity at the subgrade, then the road surface will sink. Have you considered the situation? Thank you for sharing. Kevin
Hi, This is not a concern when properly designed. Soil type, infiltration rate and load bearing capacity must all be considered. Additionally, the rate at which the water reaches the soil and infiltrates is not such that erosion would occur. In the case of weaker soils, amendments can be applied to reinforce.
Please take the road in front of your house. Design the inflow pavement, which will collect all the rain water of your house on to the pavement in fromt of your house, as well all this water filters down to the under groundwater to fill back reserves. Plan and es timate cost of project. Sell it to municipality for all houses. This will solve all water logging problems of your city. Solve water problem too. Good luck
Hi Erika, for more information on permeable pavement, check out both these articles we wrote : Part 1: pros.techo-bloc.com/how-to-build-a-permeable-pavement-part-1 Part 2: pros.techo-bloc.com/how-to-build-a-permeable-pavement-part-2 Thank you!
the water accumulated between the asphalt and the base made with sand that causes the holes, in the system presented in the video, the water flows straight to the ground, that is, it does not accumulate
Hi, I just want you to know that I am very interested in your Permeable Pavement. How can I learn more about it? I think I would like to invest in this as a business in my country.
Hello Kathleen, more information is available in our brochure. You can download it here: www.techo-bloc.com/support/resources/technical-resources/permeable-pavement-solutions/ Thank you!
Some people just do not care. A small college in Pennsylvania, named California University of Pennsylvania, drains its newly constructed asphalt parking lots at its football stadium and student housing complexes into the nearest stream, which then travels to a larger stream, and then to the Monongahela River.
1:46 is exactly where you lost me. If the point of this is to replenish the planet and lessen our imposing footprint, why would we remove natural terrain and water sources only to keep building our crummy communities?
Hello Erik, Snow removal can be done as for any other type of paving, but it is still recommended that snow removal blades be covered with a protective coating and raised 1 inch.

You're right about the last one.

When you think at the number of carparks around, this would do a decent job at minimising runoff and pollution so i think it should have a place in development.
This should be done everywhere around the world
If the installation is for light use and foot traffic and NO vehicles, can the amount and size of the stone be reduced?
Thanks Sir, love from india 😍😍
please is good for rainy places
Compliments to the 3D artist.

I wonder if these streets have the structure to support the high weights of modern cars and trucks
Hi, may I know the software tool to generate the 3D model? It was such a great work!

i want this tipe of permiable cement or what ever it is for my whole country of el salvador
What about the grass that will grow in the joints?
Hello Gabriele!

Thank you!
@@techobloc how often would it require a maintenance care at a ground with near to none soil nearby like a parking lot?
Brilliant!
Nice video
i see 2 problems. 1. ice. and 2. detritus build ups, which will block the small channels and rot creating a bad odor
It's resistant.

Hi,why put geotextile over the soil layer? The water will across the aperture and bring the sands away and there's the cavity at the subgrade,right?

How can i make a final year project like this topic😃

If you have any project report on this , can i get it
is it suitable to cover highways or expressways where length is in km
probably not the entire road surface, perhaps along the sides of the roads
We are mainly used in low volume road or pedestrian
What is the material?

Isnt water the reason of potholes?
the water accumulated between the asphalt and the base made with sand that causes the holes, in the system presented in the video, the water flows straight to the ground, that is, it does not accumulate
Song?
Water goes from concrete tube down to water table it's called pipe

it helps reduce urban sprawl. meaning that cities don't spread out as much or as rapidly preserving surrounding green spaces. that's the idea.
Hi i am doing this as my final year engineering project . so can any1 suggest me some ideas??
Hello Manoj Kumar can you did this project please give me some information soft copy
lol
But it can’t be hit with a s snow plow...
