Assess Your Needs
Proper planning is crucial before embarking on the construction of a wheelchair ramp. Carefully consider these factors to ensure a safe and functional ramp:
1. Determine User Requirements:
| Consideration | Explanation |
|---|---|
| Accessibility | Identify the location and purpose of the ramp, whether it’s for a residential entrance, public building, or vehicle access. |
| Wheelchair Specifications | Measure the user’s wheelchair, including its width, length, and turning radius, to ensure ample clearance and accessibility. |
| Disability Regulations | Review applicable codes and regulations for wheelchair ramp design standards, such as the Americans with Disabilities Act (ADA) or local building codes. |
| User Preferences | Consider the user’s preferences and mobility abilities, such as manual or power-assisted wheelchairs, and adjust the ramp design accordingly. |
| Obstructions and Safety | Identify any potential obstructions or hazards along the ramp’s path, such as steps, slopes, or narrow passages, and plan to mitigate them. |
| Slope and Length | Determine the appropriate slope and length of the ramp based on the user’s needs and disability guidelines. |
| Surface and Traction | Select durable and slip-resistant materials for the ramp surface to ensure safe and comfortable passage. |
Determine the Slope
Selecting the Appropriate Slope for Your Ramp
The slope of your wheelchair ramp plays a crucial role in accessibility and safety for users. The following guidelines will help you determine the optimum slope for your specific application:
1. Horizontal Run: Determine the length of the horizontal run (the horizontal distance the ramp covers). This measurement should be taken from the point of entry to the desired elevation at the top of the ramp.
2. Vertical Rise: Measure the vertical difference between the starting point of the ramp and the desired elevation at the top. This measurement determines the height the ramp must ascend.
3. Slope Ratio: The slope ratio is calculated by dividing the vertical rise by the horizontal run. The recommended slope ratio for wheelchair ramps is 1:12, meaning that for every 1 inch of vertical rise, the horizontal run should be 12 inches long.
4. Maximum Slope: In some cases, it may be necessary to exceed the recommended slope ratio. However, the maximum allowable slope for wheelchair ramps is 1:8, meaning that for every 1 inch of vertical rise, the horizontal run can be as short as 8 inches.
5. Transition Zones: Provide flat transition zones at both the top and bottom of the ramp. These zones should be at least 5 feet long to allow for acceleration and deceleration.
Gather Materials

- Portable ramps are lightweight and can be easily folded up and transported. They are a good option for temporary use or for people who need to use a ramp in multiple locations.
- Modular ramps are made up of individual sections that can be connected together to create a ramp of any length or shape. They are a good option for complex installations or for people who need to adjust the height or slope of their ramp over time.
- Threshold ramps are designed to bridge small gaps, such as the difference in height between a doorway and a floor. They are typically made of rubber or plastic and are lightweight and easy to install.
Permanent Ramps
Permanent ramps are the most durable and stable type of ramp, but they can also be the most expensive and time-consuming to install. They are typically made of concrete or asphalt and are attached to the ground. Permanent ramps are a good option for homes with multiple levels or for people who need a ramp that can withstand heavy use.
The cost of a permanent ramp will vary depending on the size and complexity of the installation. However, you can expect to pay at least $1,000 for a basic ramp.
| Type of Permanent Ramp | Pros | Cons |
|---|---|---|
| Concrete | Durable, stable, and long-lasting | Expensive and time-consuming to install |
| Asphalt | Less expensive than concrete, but not as durable | Can be slippery when wet |
Plan the Layout
1. Determine the Start and End Points
Establish the precise location where the ramp will begin and end. Consider factors such as accessibility, safety, and the desired slope.
2. Measure the Vertical Rise and Horizontal Distance
The vertical rise refers to the height difference between the start and end points. The horizontal distance represents the length of the ramp. These measurements are crucial for calculating the slope.
3. Calculate the Slope
The slope of the ramp is expressed as a ratio of vertical rise to horizontal distance. The ideal slope for wheelchair ramps is between 1:12 and 1:20. This means for every 1 inch of vertical rise, the ramp should extend 12 to 20 inches horizontally.
4. Plan the Turns (if necessary)
If the ramp requires turns, ensure that they are gradual and have a wide turning radius to accommodate wheelchairs. The minimum turning radius for a ramp is typically 5 feet.
5. Consider the Dimensions and Features
Width and Length:
The minimum width for a wheelchair ramp is 36 inches. However, a wider ramp (48 inches or more) is recommended for increased safety and ease of use. The length of the ramp will depend on the slope and vertical rise.
Handrails:
Handrails are required on both sides of the ramp for support and stability. They should be positioned at a height of 34 to 38 inches above the ramp surface and extend at least 12 inches beyond the top and bottom of the ramp.
Resting Platforms (if necessary):
If the ramp is long or has a steep slope, it may be necessary to include resting platforms to allow individuals time to rest or make adjustments. The recommended length for resting platforms is 60 inches.
Surfacing:
The ramp surface should be nonslip, weather-resistant, and easy to clean. Common surfacing materials include concrete, asphalt, and rubber.
Install the Ramp Supports
Installing the ramp supports involves stabilizing the ramp and ensuring its safety and stability. Here are detailed steps for this crucial step:
Preparation
- Mark the locations for the support posts using the pre-determined spacing measurements.
- Dig holes for each support post, ensuring they are deep enough to provide a secure hold.
Post Installation
- Place the support posts in the holes and backfill with concrete.
- Allow the concrete to cure according to the manufacturer’s instructions, typically for 24-48 hours.
Stringer Attachment
- Position the stringers on the support posts, aligning them with the ramp’s slope.
- Secure the stringers to the supports using lag bolts or other suitable fasteners.
Additional Support Considerations
In certain cases, additional support may be necessary, especially for longer ramps or heavily used ramps. This can include:
- Railings: Install handrails on both sides of the ramp for additional safety and support.
- Toe Plates: Add toe plates at the bottom of the ramp to prevent tripping and provide a smooth transition.
- Mid-Span Support: For longer ramps, consider adding a mid-span support to minimize deflection and increase stability.
Build the Ramp Platform
The ramp platform is the main walking surface of the ramp. It should be made of a material that is durable, slip-resistant, and easy to clean. Common materials used for ramp platforms include concrete, wood, and metal.
The platform should be at least 36 inches wide to allow for easy passage of a wheelchair. The length of the platform will vary depending on the slope of the ramp.
The platform should be built with a slight slope to allow water to drain away. The slope should not exceed 1:12, which means that for every 12 inches of horizontal distance, the platform should rise 1 inch.
The platform should be supported by a sturdy frame. The frame can be made of wood, metal, or concrete. The frame should be strong enough to support the weight of a wheelchair and its occupant.
The platform should be attached to the ground or to the existing structure in a secure manner. The method of attachment will vary depending on the materials used for the platform and the frame.
Once the platform is built, it should be tested to ensure that it is safe and accessible. The ramp should be inspected regularly to ensure that it is in good condition.
Materials for Ramp Platform
The following materials can be used to build a ramp platform:
| Material | Advantages | Disadvantages |
|---|---|---|
| Concrete | Durable, slip-resistant, easy to clean | Expensive, requires professional installation |
| Wood | Relatively inexpensive, easy to install, can be stained or painted | Not as durable as concrete, can rot or warp |
| Metal | Strong, durable, slip-resistant | Expensive, can be slippery when wet |
Add Handrails
Handrails provide stability and support for wheelchair users and prevent them from falling off the ramp. They should be installed on both sides of the ramp and extend beyond the top and bottom of the ramp. The handrails should be made of a durable material, such as metal or PVC, and should be at least 1 1/2 inches in diameter. They should be installed at a height of 32 to 38 inches above the walking surface.
The following steps will help you install handrails on your wheelchair ramp:
- Mark the location of the handrails on the ramp.
- Drill pilot holes for the handrails.
- Insert the handrails into the pilot holes.
- Tighten the handrails into place.
- Secure the handrails to the ramp.
The following table provides some additional information about handrails:
| Characteristic | Requirement |
|---|---|
| Material | Durable material, such as metal or PVC |
| Diameter | At least 1 1/2 inches |
