Hard Scapes
Ramp it Up
Decking and Railing Materials Can be Used for a
Variety of Applications, Not Just Outdoor Spaces
by Samantha Carpenter, editor of Shelter magazine.
William Orsi has built many ramps for both commercial and residential
properties, but the owner of the deck building company, Deck Builders 4 Hire
in Richmond, Va., says his favorite accessibility ramp was built for an area
church in order to provide its physically challenged members easy access to
enter.
For the project, Orsi used pressure-treated Southern yellow pine, concrete pier
blocks and hot-dipped galvanized hardware (nails, bolts, washers, etc.). The
project took him approximately two days, and he says ramps are usually straight-forward
projects, but these types of projects do give him great pleasure.
Instead of it being something for just one person, for instance, it will
provide a greater service for many people, of various age groups, Orsi
says.
There is a market for materials usually used for decking and railing systems
for aging-in-place and Americans with Disabilities (ADA) applications.
According to the National Aging in Place Council, The entry to [a] home
is [its] connection to the rest of the world
Barrier-free entryways make
it easier for a family member or friend who uses a wheelchair, or a grandchild
whos on crutches because theyve broken a leg or twisted an ankle,
to gain access to [a] home.
Many of you are already distributing outdoor products, including railings and
decking, but you may not know that many of these products arent only used
for decks but they can be used to build accessibility ramps to make a barrier-free
entrance to a home or business.
If you arent familiar with the different attributes of the outdoor products
you sell or distribute, then you could be missing out on a potential market.
I think [constructing ramps] is an opportunity for contractors that maybe
they havent thought of, especially contractors that have built decks,
says Huck DeVenzio, manager of marketing/communications for Arch Wood Protection
in Smyrna, Ga. Ramps arent that much different than a deck. With
the ADA laws, theres a need for ramps on a lot of buildings.
Jerry Tracy, a sales representative for Fiberon products, located in Columbus,
Ohio, backs up what DeVenzio says.
Tracy says his company, which manufactures a composite decking product, started
using it mainly in commercial applications, but lately he has seen the product
being used more in residential work.
I had a builder who just called me up last week in Columbus that is going
to put in a ramp, he says.
Product Advantages
With any building project, companies say there are advantages to using different
types of materials, such as treated wood, vinyl or composite products.
Wood proponents tout its products durability, rot resistance and more.
Wood makes a good choice and treated wood is the sensible choice because
you dont have to worry about it rotting or collapsing, DeVenzio
says.
Richard Kleiner, director of pressure treated markets with the Southern Forest
Products Association in Kenner, La., says treated wood has been used in access
ramps because it has high strength and treatability.
Most access ramps are usually installed in the weather and treated Southern
pine has excellent resistance to rot and other pests that attack wood, such
as termites. Treated Southern pine will last decades, he says.
He does say that the species of wood used on these types of projects is a regional
preference.
Generally codes are going to require some sort of treated wood or a naturally
durable wood like a cedar that can be very expensive. Southern treated pine
is economical, widely available, easy to work with and doesnt take any
special tools, he adds.
There are also wood products available that arent treated with chemicals.
Ron Long is president of Purewood in Kansas City, Mo., one such wood decking
company.
People like wood and working with it, and we make a little bit thicker
board thats 1 1/4-inch thick instead of standard decking that is 7/8-
to 1-inch thick, Long explains. Its a little bit beefier deck
board. Its a non-toxic, chemical-free outdoor wood product.
Vinyl and composite decking materials also have their benefits, and most companies
plug the products low-maintenance qualities.
The Low-Maintenance Appeal
Deron Manwaring, national marketing and sales manager for Royal Outdoor Products
in Milford, Ind., says his company had one of the first vinyl deck products
on the market.
When it was designed it had codes in mind and especially ADA codes, such
as slip resistance on any kind of ramp or the space between the boards,
Manwaring says. Most of the ramps that are used are used in places and
facilities that want to keep their maintenance to a minimum, and products that
they dont have to replace. Our decking has a great surface for ramps,
but most of those ramps need railings to go along with it, and a vinyl railing
system makes sense as it needs minimal maintenance, too.
TimberTech offers a 25-year limited warranty on the product, so those
homeowners who are looking to design with the future in mind know they arent
going to spend as much time as compared to a pressure-treated deck, explains
Rob Foster, TimberTechs spokesperson. It becomes a very low-maintenance
option for them, and it can provide a greater benefit over a period of time.
All the decking products are ADA-compliant for slip resistance.
Foster says hidden fasteners are also important.
These decks are grooved and allow for hidden fasteners, which are really
important because with regular pressure-treated lumber, most decks are secured
by nail and/or screw and with those boards expanding and contracting with the
heat and the water, the fasteners can possibly pop outand thats
about the last thing you want to have on a ramp when you are on a wheelchair.
The possibility of having the concealed fastener is very important in terms
of safety, Foster says.
Not so Slick
Jodene Wheeler, marketing representative at CertainTeed in Valley Forge, Pa.,
for railing and decks, says because the companys product is vinyl, there
is not a lot of maintenance that is involved with it. For a commercial
project, our product is guaranteed for 30 years, she says.
Our products are used in a variety of places because they are vinyl. The
deck material is cool to the touch and is very textured, [so its perfect
for] someone that is a little unsteady on their feet or a wheelchair is needed,
Wheeler says. When some people think of vinyl, they think plastic and
think when it gets wet it is going to get real slippery, but our product is
very slip-resistant.
Brent Gwatney, vice president of sales and marketing for MoistureShield in Springdale,
Ark., also boasts of the low-maintenance benefits of his companys product.
You arent going to have the standard maintenance you are going to
have with a wood product. You are still going to have to wash and clean it,
but you arent going to have to replace it, but its not going to
wear like a treated lumber deck thats wood in the same amount of time,
Gwatney says.
He says that his companys product is used in a number of ramp projects,
but he explains that these projects arent always without headaches.
We do quite a few of them and there is some confusion out there on ADA
Guidelines or what they would call acceptable. ADA doesnt have
an official slip-resistant test, but they have recommendations. And while some
products dont meet the slip-resistance recommendations, it doesnt
mean that they dont meet slip-resistance coding. So it can be confusing
at times, and it depends on who you work with and in what area of the country,
Gwatney explains.
And Gwatney is exactly right. There are American with Disabilities Act Accessibility
Guidelines (ADAAG), but they are not binding on private residences. However,
the ADAAG provides important guidance for building a residential ramp. When
these requirements are used in the residential code, they are often the same
or less stringent than the guidelines (see sidebar on page 18 for the ADAAG
ramp instructions).
But codes and guidelines aside, if a customer comes in asking whether your decking
and railing products can be used for aging-in-place and ADA-compliant applications,
you can simply say, yes.
Southern Pine Ramp to the
Rescue
An energetic group of volunteers, affiliated with the
Home Builders Association (HBA) of Greater New Orleans, teamed up to construct
a complex ramp. The ramp helped an elderly stroke victim confined to a wheelchair
finally be able to safely enter and exit his home.
The Southern Forest Products Association (SFPA) worked with the local HBA and
its Remodelers Council to ensure proper building practices and selection
of durable materials. SFPA member Elder Wood Preserving donated the wood products
for the entire project all pressure-treated Southern pine. The bi-level
ramp design specified No. 2 treated Southern pine 2 by 8s and 4 by 4 posts for
the framing and standard radius-edge decking on the surface. The sturdy railing
adds a nice finishing touch to the ramp.
Using a versatile product such as treated Southern pine greatly simplified
the construction process, says SFPAs Eric Gee: Unlike other
plastic and composite materials, treated Southern Pine requires no special tools
or skills.
ADAAG for Ramps
The following information can be found in the Americans with Disabilities
Act Accessibility Guidelines (ADAAG). As stated in the main article, these requirements
are usually more stringent than are required in many residential codes. You
can print a PDF copy of guidelines for ramps and other structures at http://www.access-board.gov/adaag/ADAAG.pdf.
4.8 Ramps.

ramp. The maximum slope of a ramp in new construction shall be 1:12. The maximum
rise for any run shall be 30 in (760 mm). Curb ramps and ramps to be constructed
on existing sites or in existing buildings or facilities may have slopes and
rises as allowed in 4.1.6(3)(a) if space limitations prohibit the use of a 1:12
slope or less.
4.8.3 Clear Width. The minimum clear width of a ramp shall be 36 in (915

(4) If a doorway is located at a landing, then the area in front of the
doorway shall comply with 4.13.6.
4.8.5* Handrails. If a ramp run has a rise greater than 6 in (150 mm)
or a horizontal projection greater than 72 in (1830 mm), then it shall have
handrails on both sides. Handrails are not required on curb ramps or adjacent
to seating in assembly areas. Handrails shall comply with 4.26 and shall have
the following features:
(1) Handrails shall be provided along both sides of ramp segments. The
inside handrail on switchback or dogleg ramps shall always be continuous.
(2) If handrails are not continuous, they shall extend at least 12 in
(305 mm) beyond the top and bottom of the ramp segment and shall be parallel
with the floor or ground surface.
(3) The clear space between the handrail and the wall shall be 1 - 1/2
in (38 mm).
(4) Gripping surfaces shall be continuous.
(5) Top of handrail gripping surfaces shall be mounted between 34 in
and 38 in (865 mm and 965 mm) above ramp surfaces.
(6) Ends of handrails shall be either rounded or returned smoothly to
floor, wall, or post.
(7) Handrails shall not rotate within their fittings.
