I have two 3" x 3" square holes on a sports court. They are around 2' deep. They take two long poles that support a net.
When the poles are not in the holes they fill with water when it rains (mosquito breeding area) and are a trip hazard.
Question: How can I cover these holes where the cover will be flush with the surface of the court?
What I'm currently thinking of doing, not sure if it's the right approach: Buy a 3x3 piece of lumber (surprisingly hard to find) and cut 2' lengths from it and stick those in the holes.
Problems I see with that:
- Home Depot and Lowes don't have 3x3 wood listed on their sites.
- When it gets wet I am guessing that it would swell and be difficult or impossible to remove. (I'm also guessing that there's something I could treat it with to make it water proof.)
- It would be difficult to get out even when dry. (Thinking that a small hole in the middle of the end with a sunken eye screwed into it would allow me to lift it.)
If you think that my current approach of putting a block of wood in there is the right approach then I'd love to hear suggestions about how to do it to solve the problems that I forsee. Otherwise if you have a better idea to solve this...
