How to Build a Concrete Boat Ramp?

Last Updated on October 16, 2022

Assuming you want to build a boat ramp on your own: The first step is to mark out the area where the ramp will go. Then, using a spade, dig a trench that is about one foot deep and two feet wide.

The next step is to lay down some wire mesh in the trench. After that, you will need to mix concrete and pour it into the trench. Once the concrete has dried, you can then add whatever finishings you desire.

  • Excavate the area where the ramp will be built, making sure to leave enough room for the desired slope and width of the ramp
  • Install any necessary drainage pipes or culverts in the excavated area
  • Place concrete forms around the perimeter of the excavated area, making sure they are level and plumb
  • Reinforce the concrete forms with steel rebar placed at regular intervals
  • Pour concrete into the forms, using a vibrating tool to help settle it into place and remove any air pockets
  • Smooth out the surface of the wet concrete with a trowel or float
  • 7 Allow the concrete to cure for at least 24 hours before removing the Forms and starting construction on the ramp itself

How Thick Should Boat Ramp Concrete Be?

Boat ramps are an essential part of any marina, boat launch or waterfront property. They provide a safe and easy way to get your boat in and out of the water. But how thick should boat ramp concrete be?

The thickness of your boat ramp concrete will depend on a few factors, including the weight of your boat, the tides and waves in your area, and the type of bottom you have (sand, mud, etc.). In general, most boat ramp concrete should be at least 4 inches thick. However, if you have a very large or heavy boat, you may need to go up to 6 or 8 inches.

And if you live in an area with strong tides and waves, you may need to go even thicker. When it comes to choosing the right thickness for your boat ramp concrete, it’s always better to err on the side of caution. It’s much easier and less expensive to pour extra concrete than it is to repair or replace damaged concrete later on.

So if you’re unsure about what thickness is best for your situation, don’t hesitate to consult with a professional contractor who can help you make the determination.

What is the Best Angle for a Boat Ramp?

If you’re looking to build a boat ramp, there are a few things to consider. First, you’ll need to decide on the type of ramp you want. There are two main types of ramps: fixed and floating.

Fixed ramps are attached to the shoreline or dock, while floating ramps can be moved and positioned as needed. When it comes to the angle of the ramp, it’s important to strike a balance between too steep and too shallow. If the ramp is too steep, it will be difficult for boats to get on and off without hitting bottom.

If it’s too shallow, however, water will quickly build up and make it difficult to launch boats. The ideal angle for a boat ramp is about 10 degrees from horizontal.

How Deep Should a Boat Ramp Be?

A boat ramp should be deep enough to allow a boat to float freely and without hitting the bottom. The average depth of a boat ramp is about 8 feet. However, some ramps can be as shallow as 6 feet or as deep as 10 feet.

It all depends on the size and type of boat that will be using the ramp.

How Do You Pour a Concrete Boat Ramp Underwater?

Assuming you would like a detailed explanation of how to pour a concrete boat ramp underwater: The first step is to excavate the area where the ramp will be built. This includes clearing any vegetation and leveling the ground.

Once the area is prepared, forms will need to be set in place. These can be made from wood, metal, or plastic. The next step is to install reinforcement bars, or rebar, into the forms.

This will help to strengthen the concrete once it is poured. After the forms and rebar are in place, you are ready to start pouring the concrete. To do this, a hose must be placed into the water at one end of the forms and concrete mix pumped through it until it reaches the other end.

It is important to have someone at each end of the hose during this process so that any clogs can be quickly removed. As the concrete mix comes out of the hose, it will need to be tamped down so that air pockets do not form. Once all of the concrete has been poured, it will need time to cure before being used.

Depending on temperature and humidity levels, this could take anywhere from 24 hours to a week. Once cured, your new boat ramp will be ready for use!

Concrete Boat Ramp Planks

If you’re looking to add a concrete boat ramp to your property, you’ll need to purchase concrete boat ramp planks. These planks are specially designed to withstand the weight and wear of boats, trailers, and other vehicles. They also provide a slip-resistant surface that will keep your ramp safe for users.

When choosing concrete boat ramp planks, it’s important to select a product that is durable and long-lasting. You should also consider the size and weight of the vehicles that will be using the ramp. The thickness of the plank is also an important factor to consider.

Thicker planks will be more durable, but they may be more difficult to install. Once you’ve selected the right concrete boat ramp planks for your needs, you’ll need to install them properly in order to ensure a safe and stable surface. This process begins by excavating a trench for the footing of the ramp.

The depth of this trench will depend on the thickness of your chosen plank. Once the trench is dug, forms must be set in place and filled with concrete. After the concrete has cured, the forms can be removed and your new ramp is ready for use!

Precast Concrete Boat Ramp Cost

Precast concrete boat ramps are becoming a popular choice for many marinas and waterfront property owners. There are many benefits to using precast concrete, including the fact that it is extremely durable and has a long lifespan. Additionally, precast concrete is very easy to maintain and does not require much in the way of repairs or upkeep.

One of the most important considerations when choosing a precast concrete boat ramp is cost. These structures can be quite expensive, but there are ways to save money on the overall project. One way to do this is to purchase your materials from a reputable supplier who offers discounts for bulk orders.

Another option is to work with a contractor who specializes in installing precast concrete boat ramps. By doing your research and getting multiple quotes, you can be sure that you are getting the best possible price on your new ramp.

Boat Ramp Construction Methods

There are many ways to construct a boat ramp, but the most common methods are either by using pre-cast concrete or building a ramp with interlocking blocks. Pre-cast concrete is the more popular choice because it’s less expensive and easier to install. Interlocking blocks are typically used for temporary ramps or in areas where pre-cast concrete is not an option.

When constructing a ramp with interlocking blocks, it’s important to make sure that the blocks are level and secure. The last thing you want is for your boat ramp to collapse while you’re trying to launch your boat! To ensure stability, it’s often necessary to use reinforcement rods or cables when building a ramp with interlocking blocks.

No matter which construction method you choose, there are a few things to keep in mind when designing your boat ramp. First, make sure the slope of the ramp is gentle enough for safe launching and loading of boats. Second, consider the wave action at your launch site – you don’t want waves washing over your boat ramp and damaging it (or worse, capsizing your boat!).

Finally, be sure to leave enough room at the top of the ramp for people to safely walk around boats that are being loaded or unloaded. By following these guidelines, you can be sure that your boat ramp will provide years of trouble-free service!

How to Build a Small Boat Ramp

Are you looking to add a boat ramp to your property? If so, you’ll need to take a few things into consideration before getting started. Building a small boat ramp is a great way to make your waterfront property more accessible and enjoyable.

Here are a few tips on how to build a small boat ramp: 1. Choose the right location. When selecting a location for your boat ramp, be sure to consider the slope of the land and the depth of the water.

You’ll want to choose an area that is flat and has deep enough water for your vessel. 2. Make a plan. Once you’ve selected the perfect spot for your boat ramp, it’s time to start planning!

Draw up a design or sketch of what you envision for your ramp. This will help you when it comes time to purchase materials and start construction. 3. Gather materials.

Now it’s time to gather all of the materials you’ll need to build your boat ramp. Be sure to select durable lumber that can withstand the elements and heavy use. 4x4s or 6x6s are typically used for this type of project.

Other supplies include concrete, rebar, screws, nails, and hardware cloth (to keep animals out).


Building a concrete boat ramp is not as difficult as it may seem. With the proper planning and execution, any do-it-yourselfer can complete this project successfully. The first step is to determine the location of the ramp.

It is important to find a spot that is level and has good drainage. Once the location is determined, the next step is to excavate the area for the ramp. The depth of excavation will depend on how high the finished ramp needs to be above water level.

After excavation, forms need to be built in order to pour concrete into. These forms can be made out of wood or metal, but they must be strong enough to hold the weight of wet concrete. Once the forms are in place, reinforcement bars (rebar) should be placed inside them before concrete is poured.

After pouring concrete into the forms, it needs to be smoothed out with a trowel and left to cure for at least 24 hours before removing the forms. Once cured, your new boat ramp will be ready for use!
