Intro to Poured Rubber Surfacing

Poured in Place Rubber is a unitary safety surfacing system that has gained popularity in the last couple of decades in the playground and sports arena. It has several advantages over traditional surfacing systems such as mulch or tiles. The rubberized surface forms one continuous layer without seams or edges and can be installed to fit any shape area. It comes in many colors and can be combined to create unique shapes such as logos. It is compliant with ADA standards (American Disabilities Act) and, with the right care, it can provide years of fun and safe play for your kids.

Most poured in place rubber systems consist of two layers:

  1. An impact attenuation layer, also called the base layer or the buffings layer (because it consists of tire buffings). This layer’s thickness goes hand in hand with the fall height of the equipment in the area. For example: A two inch base layer is typically adequate for equipment that has a 5 foot fall height.
  2. A wear layer that is typically made out of EPDM granules. This is the colorful layer that coats the base layer. Both layers are mixed with a polyurethane binder (Either aromatic or aliphatic glue), and then poured and hand troweled right on site, hence the term “Poured in place rubber surfacing”. (Note: In the UK, it is referred to as “Wet Pour system”)

What damages poured in rubber surfaces?

Like anything else, your poured in place rubber will require proper maintenance and repairs to look its best and perform properly. Although some vendors sell this expensive surfacing as a maintenance-free system, this is not entirely true. Anything out there needs maintenance. In the case of the poured rubber, here is a list of things that will degrade or damage your playground rubber surface:

  • Harsh UV rays degrade the polyurethane binders first used to mix the rubber granules. These binders need to ultimately be replenished to achieve system longevity.
  • High traffic areas such as slide exits and areas under swings will wear out faster than the rest of the surface.
  • In northern states, people complain that their rubber surface shrank, exposing a gap between the rubber and the surrounding grade. This gap typically leads to tripping hazards.
  • Vandalism and accidents can damage the surface. We have seen all types of damages resulting from stiletto heels to sharp chair and ladder legs. Landscapers and fencing companies call us all the time asking for tips to repair the rubber surface they have damaged.

Our poured in rubber Repair and Maintenance Products

Trassig Corp. (The owner of has been installing and maintaining poured in place rubber surfaces in one of the harshest environments for over a decade. Based in New England, the company has developed a unique expertise in this field. Clients have sought us out from all over the country to solve both unique and common problems they were having with their poured in place surfaces. The company then started doing more repairs to existing surfaces as well as installing new ones. Frustrated with the materials and tools available in the market, Trassig developed its own in-house products that were used and tried in the most demanding situations. A few years ago, the company decided to offer these products to other contractors and as do-it-yourself solutions to playground owners.

The following are the products we sell:

Poured in Place Rebinder

A clear top sealing product that rejuvenates your surface and rebinds the granules. The first stage of poured in place surface deterioration is granulation (where rubber granules come loose when you scuff your foot along the surface). As soon as you see signs of granulation, applying a coat of rebinder will save you countless headaches and loads of money by catching the damage before it progresses into the more severe stages of damage from cracks to holes and ultimately system failure. Our rebinder will not darken the surface, is environmentally friendly and most importantly will not harden your surface.

Poured in Place Patch kits

Once the damage on your poured in place surface has progressed to the development of holes and cracks, our patch kits are the proper solution. They can also be used to fill the gaps that sometimes occur on poured in place surfaces located in colder regions. We offer two types of patch kits: a base layer patch kit, which is intended to repair the impact attenuation (buffings) layer. And wear layer patch kits. These are available in solid colors, a standard choice of color combinations, or a custom mix.

Note: After patching we recommend sealing the entire surface with Poured in Place Rebinder to ensure that more holes don’t continue to develop.

Poured in Place Extender

A solution of last resort to poured in place rubber surfaces that are beyond rebinding or patching. This product will completely encapsulate your surface in a new rubberized layer, giving your surface a brand new look and extending its lifespan significantly.

Poured in Place Sanitizer

When we read a study showing that public playgrounds are dirtier than public toilets, we sought to offer a sanitizing product to complete our line of poured in place surface maintenance products. The sanitizing system hooks up to a regular garden hose and kills 99% of the germs commonly found on the surfacing. It can also be safely used on playground equipment as well.

For Poured in Installers

We are a one-stop-shop for poured in installers and contractors. We offer the best binders (Aliphatic and Aromatic), buffings, and EPDM granules. We also offer training for dealers and installers nationwide.
