Baller ScarletArrow Posted July 13, 2018 Baller Share Posted July 13, 2018 Our lake is a man-made. The boat ramp is a little short and uneven. During August and September, the dry season in Ohio, the water level gets low and you have to put your trailer in so deep that it drops off the concrete at the end of the ramp. How would you go about extending the ramp? What kind of engineering would be involved to get an additional 5 - 10 feet at the end of the ramp that's under water?

Baller LeonL Posted July 13, 2018 Baller Share Posted July 13, 2018 I saw an extension project in FL a few years back. They poured a formed concrete slab on their existing ramp and after a few of cure time they pushed it out with a front loader. You could always lower the lake level at the end of your season and pour more concrete conventionally. Link to comment Share on other sites More sharing options...
DynaSkiPete Posted July 13, 2018 Share Posted July 13, 2018 Does the area naturally get deeper after the end of the concrete? If so just carefully put in some pre-made concrete slabs. You will need a big crane and the ability to make or buy suitable slabs to add on. Then the only problem is the potential for one surface being a difference height than the other where they meet together. I assume you don't want to lower the lake and replace the entire landing surface? Link to comment Share on other sites More sharing options...
Baller BraceMaker Posted July 13, 2018 Baller Share Posted July 13, 2018 Aluminum dock plate and some chain? Slide it off the ramp when the level goes down, haul it out with the chain when it comes back up. Or just pour more ramp. Link to comment Share on other sites More sharing options...
Baller oldjeep Posted July 13, 2018 Baller Share Posted July 13, 2018 https://oldcastleprecast.com/oldcastle_product/boat-launch-panel/ If you live where there is winter then build yourself a wall right before winter and then start pumping and digging once the water starts to be less liquid Link to comment Share on other sites More sharing options...
Baller skiep Posted July 13, 2018 Baller Share Posted July 13, 2018 At my lake we simply took the bucket on a large track hoe and pushed the existing slab deeper into the water then formed and poured a new section on dry land. Lake 38 Link to comment Share on other sites More sharing options...
Baller ForrestGump Posted July 13, 2018 Baller Share Posted July 13, 2018 You're making this too complicated. Concrete sets up fine under water. My dad was a custom home builder and built mostly homes around lakes in texas. We'd form up bulkheads and ramps in the water, order a more dry mix, and pour it. For the ramps, we'd then bullfloat the surface under the water. The section poured under the water won't be as pretty or consistent as above. But the concrete will displace the water and set up just fine. Link to comment Share on other sites More sharing options...

Baller aupatking Posted July 20, 2018 Baller Share Posted July 20, 2018 I’ve seen it done like @LeonL says. I like the sound of @skiep method too. Link to comment Share on other sites More sharing options...
