Permeable Paving is used when:-
Water penetration through a hard top 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. The resin percentage is varied for a “hard or soft substrate”. 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.
Beware of installers only offering this one service. ( One-dimensional )
Permeable Paving can cause numerous negative / expensive issues in the wrong situation.
Researching many resurfacing options, will reveal the most suitable / guaranteed option for your project.

Notes:- 1) Preparation and application is determined by sub-surface type? porous? and compaction level? 2) We install an underlying fiber mesh, if sub-surface movement is expected. 3) Our aggregate to resin mix ratio will vary, depending if water penetration is required or not? Ie:- If existing sub-surface is not porous, we use higher % of resin, otherwise water is trapped in paving. |
