090. Frequently Asked Questions
Which side up should the boards be installed?
At planted areas the diffusions holes should point upwards. Under paved or boarded areas the diffusion holes should be pointing downwards.
Why polystyrene?
Polystyrene retains its shape well in high summer temperatures and experiments support the view that even after 50 years of use it will not alter its form substantially.
Why do you recommend a draining layer shaped on both sides?
A double moulded layer ensures that there are two ways for air to get in and water to get out enhancing the efficiency of drainage and ventilation.
