If you or someone you know uses a wheelchair, building a wheelchair ramp can be a great way to improve accessibility and independence. Wheelchair ramps can be built in a variety of ways, depending on the specific needs of the user and the layout of the property. However, all wheelchair ramps must meet certain minimum standards in order to be safe and effective.
The first step in building a wheelchair ramp is to determine the best location for the ramp. The ramp should be placed in a location that is convenient for the user and that does not obstruct access to other areas of the property. The ramp should also be built on a level surface and should have a gentle slope. The slope of the ramp should not exceed 1:12, which means that for every 12 inches of horizontal distance, the ramp should rise no more than 1 inch.
Once you have determined the location and slope of the ramp, you can begin to build the ramp. The ramp can be built using a variety of materials, including wood, concrete, or steel. However, wood is the most common material used to build wheelchair ramps. To build a wooden wheelchair ramp, you will need to purchase pressure-treated lumber, screws, and nails. You will also need to rent or purchase a circular saw, a drill, and a level.
Selecting the Right Materials
Constructing a safe and durable wheelchair ramp requires selecting the appropriate materials. Here are key considerations for each material type:
Wood
Pressure-treated lumber is a popular choice due to its resistance to rot and moisture. Consider southern yellow pine, redwood, or cedar for their strength and durability. Ensure wood is free of knots and warping.
Advantages:
- Durable and cost-effective
- Can be stained or painted to match surroundings
- Easy to work with and customize
Disadvantages:
- Requires regular maintenance and sealing
- Susceptible to moisture damage if not properly treated
- Can become slippery when wet
| Material | Advantages | Disadvantages |
|---|---|---|
| Pressure-treated lumber | Durable, cost-effective | Requires maintenance, moisture damage, can be slippery |
| Southern yellow pine | Strong, durable | Knots, warping |
| Redwood, cedar | Strength, durability | Knots, warping |
Determining Ramp Slope and Dimensions
Slope
The slope of a wheelchair ramp is the ratio of the vertical rise to the horizontal run. It is typically expressed as a percentage. For example, a ramp with a slope of 5% rises 5 units vertically for every 100 units of horizontal distance.
The maximum allowable slope for a wheelchair ramp is 12%, according to the Americans with Disabilities Act (ADA). However, it is preferable to build a ramp with a slope of 5% or less for ease of access.
Dimensions
The dimensions of a wheelchair ramp are determined by the following factors:
- The slope of the ramp
- The width of the ramp
- The length of the ramp
The width of a wheelchair ramp should be at least 36 inches to allow for a wheelchair and an attendant to pass side by side. The length of a ramp is determined by the slope and the height of the obstacle being overcome.
| Slope (in percentage) | Horizontal Run in Inches per Inch of Rise |
|---|---|
| 5% | 20 |
| 10% | 10 |
| 12% | 8.3 |
Building the Ramp Base
The ramp base provides the foundation for your wheelchair ramp. It must be strong, stable, and level to ensure a safe and accessible pathway. Here are the detailed steps to build a proper ramp base:
1. Mark and Excavate the Base Area
Determine the location and dimensions of the ramp base, ensuring it meets building codes and accessibility guidelines. Mark the area with stakes and string, then excavate 4-6 inches of topsoil to create a level surface.
2. Install Gravel for Drainage
Spread a 4-inch layer of crushed gravel over the excavated area. This will provide drainage and prevent water from pooling beneath the ramp. Use a tamper or compactor to pack the gravel firmly.
3. Create a Reinforced Concrete Base
Construct a reinforced concrete base to provide structural support for the ramp. Here’s a detailed guide for creating a sturdy concrete base:
- Set formwork around the perimeter of the ramp base area, ensuring it is level and square.
- Install rebar reinforcement according to engineering specifications or building codes. This will reinforce the concrete and increase its strength.
- Pour concrete mix into the formwork, filling it completely. Use a screed to level off the concrete surface and remove any excess.
- Cure the concrete according to recommended guidelines, which may involve misting or covering it to prevent cracking.
- Remove the formwork once the concrete has gained sufficient strength, typically after 7-10 days.
The thickness of the concrete base should be determined by an engineer based on the ramp length, slope, and expected loads.
Installing Support Posts and Handrails
To ensure the stability and safety of your wheelchair ramp, support posts and handrails are essential components. Here’s a detailed guide to installing them:
Support Posts
1. **Placement:** Position the posts along the sides of the ramp, approximately 3-4 feet apart. Ensure they align with the studs in the wall or foundation.
2. **Excavation:** Dig holes for the posts, deep enough to extend at least 2 feet below the frost line in your area.
3. **Post Installation:** Insert the posts into the holes and fill the voids with compacted gravel or concrete. Allow the posts to cure fully.
4. **Securing the Posts:** For added stability, secure the posts to the ramp and the wall or foundation using galvanized lag bolts or heavy-duty screws.
Handrails
1. **Materials:** Choose corrosion-resistant materials such as aluminum, stainless steel, or PVC for the handrails.
2. **Spacing:** Install the handrails at a height of 32-34 inches above the ramp surface and at a distance of 12-18 inches from the ramp edges.
3. **Brackets and Mounting:** Use heavy-duty brackets to secure the handrails to the support posts or the wall. Ensure the brackets are strong enough to withstand the weight and force applied by users.
4. **Extending the Handrails:** If the ramp is longer than 6 feet, extend the handrails beyond the end of the ramp by 1-2 feet for added safety.
| Handrail Requirements for ADA Compliance |
|---|
| – Continuous, unobstructed length |
| – Smooth, rounded edges |
| – No sharp projections or pinch points |
| – Securely anchored and strong enough to support 200 lbs. |
Connecting the Ramp to Your Home
