Frequently Asked Questions

​Answering all your Rubaroc questions!

What is Rubaroc?

Often initially confused with cork, Rubaroc is a rubber surfacing that can be applied in both indoor and outdoor environments.  Made of high-quality EPDM rubber granules combined with a specially formulated urethane resin, Rubaroc is a virtually indestructible, non-slip surface that looks fantastic.

Is it new?

No.  The technique for installing rubber surfacing like Rubaroc originated in France 75 years ago.  Rubaroc has been installed around the world in its current form for 30 years.  

How is Rubaroc installed?

Only certified, trained installers apply Rubaroc. Typically installed by a crew of three, the rubber granules are mixed with the resin on site, wet poured like concrete then hand finished with a trowel.  It can be a labour-intensive process but an experienced hand ensures quality every time.

Can Rubaroc be applied over cracks in concrete or asphalt?

Yes!  Even severe cracks can be filled and covered with Rubaroc without too much concern for tearing.  Minor cracks and expansion joints are easily covered and never seen again!  Your GTA Safety Surfacing representative will inspect any existing cracks and advise on how to best handle them.

Can Rubaroc be applied on stair risers?

Yes!  The process is similar to applying Rubaroc on a flat surface and can create a seamless look top to bottom.

How long does it take to install?

Installation time can vary depending on design complexity or use of multiple colours etc., but the average pool deck, patio or porch is done in a day. 

How soon can I walk on it?

Several factors affect curing time - primarily temperature and humidity.  For outdoor projects in the summer months, Rubaroc installations are generally usable within 24 hours.  In the spring and fall, that may extend to 48 hours.  Your GTA Safety Surfacing representative can advise in more detail at the time of installation.     

Is the rubber surfacing slippery when wet? 


The rubber itself combined with a slightly textured surface ensures Rubaroc is non-slip even when wet, much like a rubber bath mat.   

What colours are available?

The overall colour of your Rubaroc surface is actually a blend of 2-4 solid colours mixed in a specific proportion.  GTA Safety Surfacing offers eight standard colours for your convenience but custom mixes are also available.  Your colour options are just about endless so be sure to ask if you're thinking about getting creative!

What substrates will Rubaroc cover?

Rubaroc can be installed on most solid substrates such as concrete, asphalt, wood, aluminum, steel and some types of plastic.  It can also be installed on compacted crushed stone for creating pathways or extending existing surfaces. 

How will the weather affect my Rubaroc?

Rubaroc systems have been proven over 30 years to cope with the harshest environments including the scorching deserts of Arizona and the harsh winters of Canada. 

Can I shovel it?

Yes!  Once cured, Rubaroc requires a hammer and chisel to take it up but we still recommend a plastic shovel without a steel edge.

Can I salt it?

Yes!  One of the many advantages of EPDM rubber over similar alternatives is its high chemical resistance. 

Does Rubaroc get hot in the sun?


Heating is most influenced by colour but generally, it’s cooler than concrete and asphalt because the pores trap moisture and create airflow that helps maintain a low surface temperature. 

Will Rubaroc delaminate in the freeze/thaw cycle?


Delamination is caused by water getting between two surfaces and driving them apart as it freezes and expands.  Rubaroc installations require the substrate to be primed and sealed with the same resin used to bind the rubber together.  This ensures that water cannot get between the surfaces.

Will the colour fade?


Everything fades in the sun.  It’s only a question of how much.  The EPDM used for Rubaroc installations is extremely UV stable and will maintain its full colour for many years.  Rubaroc has been used extensively in California, Texas, Arizona, Florida, the Caribbean and Australia, which are among the world’s harshest environments for UV.

Is Rubaroc tested?

Rubaroc has undergone many tests over the years including UV stability, critical fall heights, stain resistance and fungus & bacteria growth.  Each test has satisfied the strictest requirements.  All Rubaroc surfacing materials have ISO 9002 certification and have been tested by the NSF (National Sanitation Foundation). 

What happens to the water that drains through?

The water filters through to the substrate and will naturally drain in whatever direction it’s allowed.

How do I clean Rubaroc?


Rubaroc looks and performs best with regular cleaning.  A garden hose with diluted dish soap can be used casually to remove light soiling but a carefully managed pressure washer is often required for tougher stains.  For really stubborn stains, we offer a specialized product called RubaClean as well as a cleaning service.   

What happens if my Rubaroc needs repair?

Whether it’s accidental damage or underground repairs, your Rubaroc surface is usually easily repaired.  Because Rubaroc is rubber based and granular in nature, removing the damaged area and re-pouring additional colour-matched mixture will make repairs straight forward and virtually un-detectable.

What is the warranty period?

GTA Safety Surfacing offers a 10 year, limited warranty on the materials and installation.
