Did the brainiac's build a retention wall for Poly

.....did Gold Circle and Martin Collins think to build a deep enough water retention wall between the turf track and poly track.....if not....you can kiss the grass good bye..... :blink:

Muti explain please.

Multi Musselburgh has a poly bend and grass straights, and they race on Jumps and the flat over it, seems to work fine

......the poly has a very porous layered structure to allow water to pass though it with ease....if no or not deep enough retention wall or dam was built between the two tracks.....the water on the turf will always move towards the poly for ....a) negative pressure b) move towards the ocean due to gradient and tidal water table....so in dry conditions the more you water the turf the more water escapes to under the poly... :dry:

.....but Durban ain't Musselburgh....the climatic conditions are poles apart....
