Permeable Paving is used when:-

Water penetration through a hard surface is required during rain, to reduce storm water runoff and recharge the water table etc. This helps reduce pollution in our rivers and oceans etc, plus reduce flood damage. The stones or aggregate we use, come in a range of colours and sizes to match surroundings.  Permeable Paving is also used when:-
1) Exposed aggregate look on existing concrete.   2) Sub-surface is unsound.   3) Safe grip and looks count.
These 3 links help explain the many great benefits. 

Any concrete, anywhere improves with our services.

Permeable Paving thickness guide.

Aggregate size

Hard non-porous sub-surface:- Concrete; Slate; Tiles; Non-porous asphalt.

Medium strength sub-surface:- Pavers; Stones; Broken concrete.

Soft porous sub-surface:- Gravel; Timber decks; Soil; Porous asphalt.

Notes:-   1) Preparation and application is determined by sub-surface type? porous? and compaction level?

                2) An underlying fiber mesh should be placed, if sub-surface movement is expected.

                3) Aggregate to resin mixing ratios will vary depending if water penetration is required or not.           Ie:- If existing sub-surface is not porous, use higher % of resin, otherwise water is trapped inside paving.
