Mr Lout
A lesson in how it should be done, and you recycle as well- what a guy: 
Wish we could find chalk at any depth around these parts

BCO's maybe not asking yet for cells, crates etc, but it will come.
SUDS have to be incorporated into any new build developments ( may not be in all ares of uk yet )and it will no doubt start coming into extension, patios etc.
Councils are going big time into environmentally friendly, recycled and sustainable products, carbon footprints, co2 emmissions etc and incorporating into planning criteria.
There are various types and manufacturers of cells, crates, hydrochambers, tanks etc.
You have to watch out for loadings when installing ( some are only suitable for non trafficed areas.)
One drawback with crates is that they can tend to silt up ( depending on ground conditions)

thats why we use gulleys now for rainwater and the multitrack
i am all for using crates but they are blooming expensive
i used to do a soakaway on a saturday for £100 inclusive
with crates ,multitrack,back inlet gulley,5 m 110 pipe and spoil removal (say a miniskip) you are looking at £4-500
which people balk at

There seems to be quite a bit of variation in the price charged for the crates. At Civils last week, one supplier was telling me we shouldn't be paying more than 25 quid for a quarter-cube crate (500x500x1000mm), but I've never seen 'em for less than 48 quid.
What prices are you paying?

i was paying £48 after discount. the bm's don't like stoking them for some reason.
It needs to become the norm to install them then the price war will begin

There are a lot of different crates on the market, and the prices vary depending on quantity, spec etc.
To my knowledge the prices to contractors varies from around £85 - £95 mtr3 depending on quantities and spec.
One point worth mentioning! Be wary of loadings and spec particularly if installing in trafficed areas

i am sure i paid about £40 a crate but that was the garden only ones
still works out £160 for a glorified load of beer crates
hardcore is free
btw what is the spec for filling down the sides of the terram if you use crates??
in my ignorance i used pea shingle as it was all i could think of at the time?

hat is the spec for filling down the sides of the terram if you use crates??
i used crushed concrete on both mine, one was a drive, but 20mm shingle is fine in a garden

Pea shingle is fine as a backfill material

I have seen whin dust being used to surround the geotextile, then backfilled with AsDug.
Specs vary from manufacturer to manufacturer and application.

I paid £24 plus vat for each crate, from a national BM, these were the type that are not supposed to be used in structural situations, i.e. not under car trafficked areas, however, it was a couple of quid more for the structural ones.
Having consulted the local BC they wanted either the crates or a honeycomb brick built soakaway to be left empty, i.e. not to be filled clean gravel/hardcore. Perhaps the local building control demands are causing the BM locally to stock and therefore compete on prices.
The crate manufacture I was using recommended 4" of clean 10mm gravel all round the crates and Terram 3000, non-woven geotextile, which is a 300g/m3, however I couldn't get a sensible price on this (best quote was nearly £1000, for a big roll I wasn't going to use), so I opted for TDP115.

Recently paid in the mid £20s for the lightweight stuff from of all people T.P, last year on a big order we were down to £17 a unit from the same outfit.

On a job recently we put cordex around the steel cages of column bases and backfilled with hundreds of tons of shingle to avoid compacting prior to infilling with concrete. we were made to dig it all out after and replace with crush and run and type one. i reckon its ok for drainage backfill but not around load bearing structures.
