As soon as the concrete hardened on the new Jonas Park basketball court in the fall of 2010 it was evident that there were a
number of areas where rain water would collect. That is most unfortunate. The court should have been slightly higher along
the central spine and tapered off to the sides to shed water. More recently the installer has made saw cut lines which partition
the court into 24 rectangles. It is expected that future crack line of the concrete will be along those lines. Some drainage
may occur at these lines as well.
In the rainy spring weather the court was usually impaired due to the water puddles here and there. To try to get a handle on the
problem I poured 16 large buckets of water on the dry court on May 30/11 on a nice sunny, warm (26 C) day. That revealed the low spots.
Then I took pictures of the court periodically.
The first pic shows the court about 12 noon.That was about an hour after the original water was poured on the court.

And at 6 pm
And lastly, the next morning at about 6 am.
So. What is to be done? The biggest problem is the large puddle in the middle. It's over 1/4" deep and lasts a long time even
under very good drying conditions. A cut line goes through its middle but the water does not drain well. The court has a one year
guarantee which will expire in the fall of 2011.
Apart from replacing the whole court what solutions remain? The Seeley's Bay court has a vinyl covering. I have heard of drilling small (1 inch?) holes in the concrete and forcing high pressure concrete in to raise the slabs. A 1" hole at the centre of the main puddle would likely hasten its drying. Finally, we can do nothing at all and leave the court as a not-so-great facility.
