Rooftop Pavers

Q: What sizes do your rubber roof and patio pavers come in? +
RubberForm offers roof pavers that are 24” x 30” (5 sq. ft.) available in 1.5” and 2” thick with stand-offs so water will drain underneath.
Q: What colors do your roof pavers come in? +
Our most common colors are gray, red and black.
Q: I see a lot of rubber pavers and playground molded rubber tiles, what makes yours different? +
RubberForm’s roof paver is made specifically for the roof, and molded where there is no porosity in the rubber for water or the elements to infiltrate.
Q: How do you handle drainage so water will drain off the roof? +
RubberForm molds in 3/8” stand-offs on the bottom of the rubber.
Q: Are your rubber pavers flexible and soft? +
No. We mold them in 2 formulations - all rubber and with plastic eWaste. The eWaste makes them hard and concrete, a unique RubberForm development. We can also mold with 100% recycled tire rubber. Request a sample to see the RubberForm difference for yourself!
Q: How much does your 20” x 30” x 2” thick, 5 sq. ft. paver weight? +
10 pounds per square foot. Concrete is 25 pounds per square foot.

Spill Containment

Q: What size of spill containment berm/dikes do you offer? +
We offer 5 sizes of spill berm and spill dikes and two different rubber materials, with other rubber material available upon request. Our extruded EDPM rubber spill berms come in 2” x 2”, 4” x 4”, 6” x 6” and a 2” high drive over berm, these are all extruded in 10’ lengths. They are in a pyramid, peaked shape. Our molded crumb rubber product (SBR rubber) is 4” tall x 6” wide x 65” long. This is our most economical product and comes pre-drilled, ready for installation.
Q: Do you offer custom fabrication services - cutting and drilling - or will I have to do it myself? +
RubberForm has a custom fabrication services – cutting and drilling - department that can custom fab per your specification drawing for your spill containment project. There is a charge for this custom fabrication service. Email your specs to to access these services.
Q: Can I cut your rubber berm and fabricate myself? +
Yes, with the proper tools you can cut and fabricate on-site. You will need a radial arm or chop saw with the proper saw blade. We offer an installation guide so you can fabricate and install on-location. You can download it here
Q: Which spill berm is best for me? +
The EPA/DEC have guidelines for this SPCC – Spill Containment Counter Measure requirement. Based on the SPCC requirement, you need to contain 110% of the stored liquids on premise. We have a spreadsheet that provides a rough estimate of the height and size containment berm you will need. Please consult with your licensed engineer/P.E. for certification and full requirements.
Q: What type of liquid will your rubber spill berms contain? +
RubberForm uses EPDM and SBR rubber for our spill berm. Please review the Rubber Elastomer Chemical Resistance Charts to determine if the rubber compound will work (Chart 1, Chart 2). Consult with your P.E. or engineer to verify.
Q: How many bolts do you recommend for the spill containment berm? +
We recommend bolting down every 1 ½’ to 2’. Our rubber berm needs to be sealed/caulked/glued down as well. However please consult with your P.E. and engineer for your specific project requirements.
Q: Do we need to bolt and glue our berm down? +
Definitely glue/seal/caulk your berm down. This creates the seal for the spill berm. Not all surfaces are level and the glue/sealer/caulk should fill in the holes or gaps on the surface. We also recommend bolting down in place, however this is up to the customer and your P.E./engineer’s recommendation. If it is in a high traffic area, we highly recommend bolting and sealing/caulking/adhering in place.
Q: How tall of a spill berm do I need? +
According to the rules governed by the EPA’s SPCC, your spill containment berm needs to hold more than 110% of the total liquid stored on your location. You would need to engineer the volume of liquid that fits into the square foot area you have to work with. If you need help, please give one of our specialists a call. For a rough estimate of the height and containment berm needed, use our spreadsheet.
Q: I need to drive in and out of the containment area. Do you offer a ramp solution for a drive-in containment area? +
Yes. We have a couple different solutions for this scenario. We have a drive-over ramp that can be attached to our 4” and 6” spill berm, or a modified 2.5” high speed bump. We’d be glad to help you with this over a quick phone call!
Q: What is the turnaround time for these berms? +
Depending on the spill berm type and size and the amount of fabrication we will be doing, this can range from 1 week to 3 weeks. Please email us your drawing so we can quote and provide a better timeframe for delivery.

Pipe / Hose Ramps

Q: What is the largest pipe or hose you can fit into your 2” pipe ramp? +
Our 2” pipe ramp is designed to hold up to a Schedule 40 pipe, 2 ⅜” OD, however you could fit a 3” OD hose/pipe.
Q: What is the largest pipe or hose you can put in the 4” pipe ramps? +
Our pipe ramp was engineered for the Yelomine™ and Aquamine® pipes, however our pipe ramp can fit up to a 5” pipe or hose.
Q: Do the 2” or the 4” pipe ramps need to be anchored down? +
That depends on the application and your requirement. Generally they do not, just lay down and place your pipe or hose into the open slot. Our 2” pipe ramp weighs 36 pounds and our 4” pipe ramp set (2 ramps and our interconnector) weigh a total of 84 pounds each and are generally stabilized by the inserted pipe. If they need to be anchored in place, we recommend the GRK’s RSS™ Rugged Structural Screw.
Q: Do they connect together side-by-side? +
No there is no connector piece. They lay side-by-side.
Q: How many pounds of pressure can these pipe ramps withstand? Can a dump truck drive over your pipe ramps? +
Our pipe ramps are extruded with EDPM rubber and are construction rated. They have been tested and used daily with large construction vehicles and large emergency vehicles.
Q: Will your pipe ramps support the inserted pipe or hose? +
No, the pipe or hose will need to be strong enough to hold the weight. Our ramps will disburse and hold the pipe in place as the vehicle rolls over the ramp and inserted pipe. Please see RubberForm’s YouTube channel for different vehicle demonstrations.
Q: Your 4” pipe ramp set is shown as a 3 piece unit. What are the pieces? +
Our 4” pipe ramp system consists of 2 ramps and one ramp interconnector piece that hold the 2 ramps together when the pipe or hose is inserted. The total weight of this ramp set is 84 pounds. The ramp pieces stay below the OSHA standard weight regulation for one man. These pieces easily fit together on-site and are ready for use in minutes.
Q: What is the standard length of your 2” and 4” pipe ramps? +
We extrude both the 2” and 4” pipe ramps in 36” (3’) sections. We can custom extrude up to 10’ if needed.
Q: Why don’t I just use gravel and asphalt to cover the pipe during a waterline restoration project? +
If your project is in a mandated prevailing rate area, the first time you use our pipe ramps they will be paid for. Please email RubberForm ( for our cost-justification spreadsheet so you can convince your municipality or your team to use the RubberForm pipe ramp system.

Speed Bumps / Humps

Q: What style speed bumps and speed humps do you manufacture? +
We offer our MLSB Mini speed hump that is 1 ⅞” tall, which will slow traffic to around 20 mph. Our MLSB 2.5 speed bump is 2 ½” tall, which will slow traffic to 5 to 10 mph. The most aggressive speed bump on the market is our MLSB4. This 4” tall speed bump will slow traffic to about 2 to 5 mph, and most of time to a complete stop. You will need to make sure you have appropriate ground clearance for this speed bump.
Q: How are your speed bumps and humps anchored down? +
We offer a lag bolt mounting system consisting of a lag bolt, shield, and washer to anchor into pavement or concrete. There are 4 anchor holes in each speed bump. For temporary situations, you can just lay them down or moor them in place with our GRK’s RSS™ Rugged Structural Screw.
Q: Can your speed bumps and humps be installed on a gravel road? +
Yes, with a 24” rebar spike or gravel screw can be purchased from RubberForm. These rebar spikes and gravel screws will need to be checked periodically to make sure they have not crept up and created a hazard. We have another mounting methodology for gravel and dirt road, please email for more details.
Q: What is the reflective material on your speed bumps and speed humps? +
RubberForm uses AASHTO approved yellow reflectors, 2 on our RF-MLSB2.5 and 6 on our RF-Mini-Hump. On our RF-MLSB4, we use a special-formulated safety yellow paint with reflective glass beads. We’ve found this to be a far more durable solution than the fabric road tape that many other manufacturers use. If our reflector breaks, they can easily be replaced.
Q: Are these speed bumps removable, i.e., can they be moved to a new location or taken up for winter plow season? +
Yes, if you need to remove them for the winter, just unbolt or unscrew the bolts/screws and store for the season. Seal the holes with Eco-Bond so dirt or rocks do not get lodged.
Q: How long are your speed bump/speed hump sections? +
Our line of RF-MLSB traffic calming speed bumps/speed humps come in 36” long pieces that connect with a dovetail, allowing you to create the length you need.
Q: What is the rubber material your speed bumps and speed humps are made of? +
We have custom-formulated the right material for hard traffic over many years of use. We use masticated recycled rubber, which is harder and more durable than virgin clay-filled rubber or crumb rubber and poly compounds.
Q: What is the turnaround time for your speed bumps and speed humps? +
Our speed bumps and speed humps are generally in stock and can be shipped out the following day. Larger orders (greater than 100 units) may take a little longer - please provide us enough time to manufacture and let us know when you will need delivery.
Q: Are your speed bumps and humps truly made in the U.S.A.? +
RubberForm is one of the only true U.S. manufacturers of rubber speed bumps/humps. They are made from domestically-sourced materials, manufactured and assembled in the U.S. We believe that this is the only way to maintain our high standards of quality control.

Sign Bases

Q: How much do your sign bases weigh? +
72 pounds, with a low center of gravity. We also have a 65 pound base.
Q: I’m in a high-wind area and I need a heavier sign base. Do you have a base that weighs more than 72 pounds? +
Yes, we have an add-on sign base weight that will add 75 pounds to our sign base, for a total of more than 145 pounds. It also creates a wider base, making it less likely to tip.
Q: Does your sign base come in colors? +
We manufacture an all-black sign base and a designer series sign base with gray/white speckles to mimic the look of concrete. They are offered at the same price. We also offer a safety yellow plastic cover that snaps on top of the sign base for higher visibility. The covers can be ordered in custom colors, but require a minimum order.
Q: What size signposts does your sign base support? Can I use round, square or C channel posts? +
We have 3 post hole sizes. They can be ordered with a square hole to accommodate a 1 ¾” square perforated or smooth post with drilled holes. The square hole will accommodate a C channel post. We can also custom-fabricate square tubes to any configuration. We also have sign bases with a round hole to accommodate a 2 ⅜“ standard plastic or aluminum post and a 1 ⅔” round post. The round plastic 2 ⅜“ post is our most-used sign base. Custom sized posts are available upon request.
Q: What post height do you recommend for your 72 pound sign base? +
We generally recommend a 5’ post for our sign bases. This cuts down on the wind shear that might tip the sign base over in higher wind areas. If you require a taller post, please order our 75 pound sign base weight that attaches to the bottom of our 72 pound sign base; this sign base weight will enable you to go to the MUCTD height of 7’ to 8’, use a metal post for this application. Please check with your local sign ordinances for the regulations/code.
Q: How do I lift or move your sign base? +
You can either tip-and-roll into position, or if you need an easier way to move around, we offer a sign base mover cart for longer distances. Just slip the RubberForm sign base cart underneath the sign base, tip it back with one hand, and use the wheels to roll to a new location.
Q: What is the minimum quantity I can order? +
Just one sign base. We can ship out via UPS or FedEx ground to any location or up to 15 bases per pallet via common carrier – LTL.
Q: What is the turnaround time to ship your sign base? +
Our sign base are generally in stock and can be shipped out the following business day. Larger orders (greater than 100) may take a little longer.
Q: How many sign bases fit on a pallet? +
We can ship up to 15 bases per pallet via common carrier – LTL.
Q: Why is the RubberForm sign base better than the octagonal sign bases I’ve seen other places? +
Most of these sign bases are imported, from China and Quebec (Canada subsidizes their tire recycling program as much as 50%). Our sign base is made in our plant in New York. We’ve had these octagonal sign bases tested by sign companies, and they told us the RubberForm sign base is much more stable in high winds. They did a side by side comparison test and ours won. The center of gravity is 1.5” in the center of our base - engineered for excellence.

Wheel Stops

Q: What colors do your wheel stops come in? +
We offer polygons in yellow, white, blue (for handicapped parking), red (emergency vehicles), and green (hybrid and eco-friendly cars). Custom colors are available and require a minimum order.
Q: Can I mix and match the colors on the same order? +
Yes, any combination of available colors can be ordered for the same price (except custom colors).
Q: What is the minimum wheel stop order? +
We have no minimums; our RubberForm team is very flexible! We ship via common carrier (LTL), and for smaller quantities we can ship via UPS and FedEx Ground.
Q: How do I moor/mount the wheel stops and what kind of mounting hardware do I need? +
Generally, we recommend 14” rebar for installation into asphalt, and our lag bolt hardware set (lag bolt, shield and washer) for concrete installation. If you have the time and tools to install, using the lag bolt hardware set is the best way to mount/moor the wheel stops at a similar cost to the rebar spikes. We also have Eco-Bond adhesive for applications that don’t allow you to breach the surface for installation, such as reinforced concrete or parking decks.
Q: How many lag bolts/rebar do I need? +
Each RubberForm wheel stop has 5 mounting holes. We recommend using all 5 holes to mount for optimal installation. You can use a minimum of 4 spikes/lags, however we advise that you use the two outside holes and leave the center open, this is where the tire makes contact with the wheel stop. If you choose to leave the center hole open, it can be used for a marker flag for snow plows in the winter.
Q: Will your wheel stops warp in the heat or crack in the cold? +
No, not if they are installed properly Our wheel stops are made of recycled tire rubber and, just as your tires, they don’t warp or crack. Proper installation is needed so they adhere to the ground.
Q: What are your polygons made of? +
RubberForm uses a recycled plastic polygon molded directly onto the rubber surface. This means that our polygons will not deteriorate, flake or peel-off. They should last the product lifetime of the wheel stop.
Q: Does RubberForm offer a warranty on its wheel stop? +
RubberForm stands behind our products and offers a product lifetime warranty from manufacturer defects. Under normal use, the RubberForm wheel stop should last for decades.
Q: What is the turnaround time for your wheel stops? +
Our parking lot wheel stops are generally a stock item that can be shipped the next business day from receipt of your order. Quantities over 1,000 may take additional time.
Q: How many wheel stops fit on a pallet? +
We can ship up to 56 on a heavy pallet.
Q: Are your wheel stops truly made in the U.S.A.? +
RubberForm is one of the only true U.S. manufacturers of rubber wheel stops. They are made from domestically-sourced materials, manufactured and assembled in the U.S. We believe that this is the only way to maintain our high standards of quality control.
