Gaps between block paving clogged

I have ponding in 3 areas of recently laid block paving, I suspect is due to clogging.

Marshalls SuDs Development manager states:

"Clog easily and stop working
We have been installing permeable paving for over 15 years and in all that time, we have never experienced any issues with clogging."

Its laid on the correct bedding, or so it appears, traffic over parts of the paving have been builders with various bags of waste containing plaster boards, used plaster, some muck, so in theory some of this could have spilled and done the clogging, but its all been kept mostly clean by all the rain.

I have tried scrapping out whatever seems to be clogging the block gaps, but cannot get a thin bladed spreader between the block gaps, which means I can't see if there is any kiln dried sand used, which I will assume has been, but is covered by what ever is causing the clogging.

Any one have any thoughts on how to resolve this, apart from taking it up, cleaning the blocks and then re-laying. Is Jet washing is out of the question on block paving ?

Jet washing cleans mine out, and I guess the permeable stuff has wider gaps. Maybe your sub-base is saturated though.

Umm, thats an interesting point, but 24 hours after the last rainfall I still have the ponding - I will assume the grounds saturation must abate after so many hours without rainfall.

That depends on the ground....

any pictures?

What about a wet vac on the joints in the pooling area? I always think jet washing will blast half out and the other half further in.

Not sure it's a good idea to let water through. It will sink after a while. Lifting the blocks won't be hard, a couple of flat head screw drivers or chisels will work. But it won't fix the problem permanently because soil, vegetation, dust and other debris will mix in to form a seal. The only real solution is a drain or a tilt in the paving to divert the water.
