Hi Carlos, as you know, we had similar problems at levels a couple of seasons ago,ala, john McIntyre and clan going in the wall through the kink, now called the ice rink, on the run down the front straight.which has now been remedied .as a drainlayer, yes you are right, if the ground water height is high, or the ground holds water, and not free draining, there is still ways to improve the situation, not knowing too much about the construction, or work above and below ground(soil type etc), I am only going on what I have seen on tv and YouTube, but lets say for instance, the ground is saturated, a combination of novacoil pipe running into collection sumps/tanks, then pumped away from the troubled areas to a outfall or soakpit/pond, there is always away around these problems, and my guess is that there wasn't much thought gone into it, perhaps the concrete barriers on the left side going in to the hairpin need a series of holes bored through them to allow water to flow away from the track, I don't know,.but obviously some more work is required,.although I live in timaru, I will put my hand up and offer my services to help fix the situation, levels is my first love, but like lots of people have said, puke is an icon in nz motorsport.
