Advice Welcomed

We dug out a test hole today in the basement and were fortunate to find that we didn't strike any water at 3 feet deep so it appears that we can dig as far as we will need. My goal is to get to 10 feet. I really appreciate all of your input as it forced me to go further which is going to make for a first rate sim. Thanks

Just because there is no water present at the moment does not guarantee that there won't be in the future. It could be dependent on the season, etc. Remember to allow for this possibility.
A local builder or renovation specialist could be useful for advice.

Aja is right, you need to prepare for a time when there is water present. Static pressure will allow water to seep right through concrete. Consult with a professional before proceeding any further. Sump absolutely needs to be in place before excavation. Otherwise you may wake up to your excavation full of water one morning. Also you need to excavate at least 1.5 foot deeper than the planned height of the concrete pad as you need about 12 inches of 50-75mm rock to allow water to flow through.

Thanks. I agree with everything that the three of you have said. I might end up doing the digging and earth removal but I have a total home reno going on here so there are lots of legitimate experts involved in the process. I want to do it right the first time.

Make sure to take some pics through out the process and keep us posted.

I will do that. It. I figured this was a normal thing, but it appears to be anything but normal. I will hopefully be a sounding board for future excavations..

Rope, I dug down 11 feet. It was dry as a bone. I put in a sump anyway. I forget but I thnk its code. My sump comes on a lot when there's a lot of rain. My buddy 5 miles away and close to a Lake Ontario dug down 8 feet. His sump comes on every 5 minutes 24/7/365. I like the security of a sump.

I agree. We live on the lake (Huron) so the water table will be more pronounced here.

5ft 9 inches tall ceiling 7ft 11inches lose 1/2 to 3/4 inch from mat. I can swing up to 3 wood but hitting the ceiling is on my mind. I generally hit no more than hybrid. Ill get up to 142 ball speed with the hybrid and under the right conditions it will chase out to 240yds. I game with that for sims. Im mostly working on my iron game. I need to finish the ceiling but really cant give up any more height. I have thought about taking an inch or 2 off the concrete floor to drop that mat. Does anybody have any experience doing that? Equipment to do it?
