Anyone come across this system before?

 

Infilta | Aggregate Industries

WWW.AGGREGATE.COM

A tough, hard wearing permeable block capable of handling heavy-use trafficking but with the ability to provide water...

 

Been to look at a site today where there is a problem with the gaps between the pavers becoming clogged with sediment, debris and moss / weed growth preventing the effective permeability of the surface.

 

Whilst I was there on my own, I hadn't even realised that there were 2 different types of paving - one non permeable (normal block paving) and the other permeable (infilta.)  The site foreman didn't appear to be aware either until the developer arrived and explained the difference and what the problem was.

 

Can't help but think this system is pretty much doomed to fail since the necessary gaps between the infilta blocks are certain to become clogged over the passage of time.

 

Just thought I'd throw it out there in case anyone else had encountered (or was considering) this type of system.  Anyone got any ideas about how to prevent / remedy / resolve?  I can't see the standard type of rotary wire brush or nylon brush vacuum system being particularly effective.

Pressure washer, drain jetter with a turbo nozzle, labour intensive,  Kiln dried sand should be brushed back into the joints after the blocks have dried.

There’s meant to nuffin in the joints Egger! Seems a bit daft to me.

I'll stand corrected, I can't see how the paviors will stay in place mind.

When I looked at these sort of blocks they were infilled with a coarse material. Just having a bit of a look online and crushed stone/rock is used such as: https://www.bradstone.com/products/jointing-aggregate---fixing-products/

Just had a quick Youtube and found this vid:

 

 

They have infilled the gaps with 6mm washed stone chip.  The 3 ton water drop test at the end is genuinely impressive!

 

Albeit a different product (Marshalls) rather than the Aggregate industries 'infilta' system, the principle must be similar.  

 

Makes me wonder if the developer I met today didn't realise it should have a 'filler' between the blocks.  Don't know.  I'm going to try the tech desk at Aggregate industries to see what they spec for in between the blocks.

There had to be something inbetween the blocks, they wouldn't stay in place else. Marshalls run out of RAF Huntingdon, used to service their pumping station years ago. Would you like anymore useless information?
