Frequently Asked Questions

Bison Innovative Products

What Are Bison Deck Supports & Where Do I Use Them? 

Bison Deck Supports create adjustable deck support systems for rooftop decks, terraces, over cracked concrete and even in water features. These supports allow you to create unique deck designs with a variety of materials: wood tiles, natural stone, concrete pavers or wood planking over traditional wood stringers. 

What Are The Pedestals Made of? 

High Density polyproplene plastic. There is no water penetration, so they are resistant to freeze-thaw cycles and mold. The patented adjustable design allows precise deck leveling, even when pedestals are loaded.

Where Can I Use Bison Deck Supports?

Bison Deck Supports can create a beautiful deck in no time over compacted soil or cracked concrete or can sit directly over smooth or granular roof membranes without attachment. 

How Many Deck Supports Will I Need?

Roughly one deck support for every 3-4 square feet of deck. Most concrete or wood tile decks will require about 1 pedestal per tile. For help with estimating, please contact us.

How Do I Correct For Slope Surfaces?

One Bison bottom leveler (Bison LD4) corrects for 1/4″ per foot slope. Two stacked together adjust from 0-1/2″ per foot slope. You can use up to four under one pedestal to compensate for a maximum of 1″ in height.

Which Bison Pedestal Will I Need For My Project?

To determine what Bison Pedestal would be suitable for your project, you first have to determine the surface material you plan to use. Each Bison Pedestal line offers different features including different height and weight capacities. Please contact us for help in determining what pedestal line would be most appropriate for your project. 

How To Build Steps Or Ramps With Bison Pedestals?

Stairs and ramps are often required in renovation projects to accommodate existing elevations, duct and mechanical work and other obstacles to create unique terrace designs. Stand-alone pedestal paver installations require perimeter containment at every change in elevation or step. Bison recommends that step design and handrail attachments be designed by an architect or engineer to provide adequate containment of lateral forces and to ensure safety and compliance with local codes.

What Is The Difference Between Ipe, Cumaru And Massaranduba Wood Tiles?

Ipê, Cumaru and Massaranduba are species of hardwood coming from South America. They are exceptionally durable outdoor hardwood decking materials and proven to withstand the elements (think Atlantic City Boardwalks). They all have excellent resistance to mold, termites and decay and over time, all weather to a gray patina. They can be used in a variety of applications from hotel rooftop pool decks to boardwalks, shared condo terraces, outdoor dining spaces for restaurants and bars and more. While there are slight variations in their Janka rating and grain, the differences really comes down to initial color and aesthetics.


Is Paverdeck Strong?

The EDECK platform is likely the strongest and safest deck system available. The nesting nature of the deck provides a complete structural subfloor that has been tested to over 560 lbs per square foot without collapsing - greatly surpassing the limits of the building code. Unlike other steel deck systems, we use higher strength steel than the building codes and our competition.

What Is The Expected Lifespan of Paverdeck?

Unlike other steel deck systems that rely on a paint layer for protection, we add 50% more zinc galvanizing for longer corrosion protection than our competition and the building codes require. We are the only deck system to offer anodes to provide an indefinite lifespan to our deck structure. Our structures are not susceptible to fire or termites.

What Type of Foundation Do I need for Paverdeck?

A Paverdeck foundation can be: (a) floated on-grade using concrete footing pads or concrete block; (b) installed below the frost line on concrete sonotube columns using a Bigfoot or other footing form; or (c) installed below the frost line on steel helical piles. Check with your local building office for limits.

Are There Any Elevation Restrictions With Paverdeck?

A Paverdeck installation can be at any elevation below or above grade. You can sink the beams in the ground for at-grade decks or pool surrounds, or install the deck as a second floor balcony for walkout basements. Deck support columns are typically concrete (up to 54 inches from grade) and 4x4 steel HSS pipe (up to 20-feet).

What Spans Can Paverdeck Accomidate?

The galvanized steel deck pan can span 14-feet between beams (12-feet preferred) for a residential deck, and can cantilever 39 inches over a beam - more than any wood structure can do.

Is Paverdeck Difficult To Install?

Installation is straightforward for a DIY project or your own contractor. We generally use a gasoline abrasive cutoff saw (12" or 14") or angle grinder to cut the metal. You can also use an electric circular saw with appropriate metal cutting blade. Make sure to follow all safety instructions, including using protective gloves, eye and face protection.

What are Anodes?

Our deck structure is the only decking system with anode corrosion protection technology, which will provide for an effective unlimited lifespan in your deck investment. Anodes are inexpensive and simple to install, and require inspection every 10-15 years. Installation is straightforward for a DIY project or your own contractor.

Does Paverdeck Meet Building Codes?

In Canada, the PAVERDECKTM system is suitable for use as an exterior or interior platform for residential and commercial buildings, in compliance with CSA S136-07 as referenced in the building codes.  In the United States, the PAVERDECKTM system is suitable for use as an exterior or interior platform for residential and commercial buildings, in compliance with AISI S100-12 – North American Specification For The Design Of Cold-Formed Steel Structural Members, as referenced in the sections 2210 and 2211.5 of the International Building Code, and sections R301 of the International Residential Code.

Silca Grates

What Is Silca System?

Silca System is a subflooring grid that spans the space between floor joists to provide a super strong substructure for deck flooring.

What Kind Of Deck Flooring Material Can Be Installed With Silca System?

Your deck flooring options are almost limitless: natural stone pavers, travertine, blue stone, brick pavers, slate, marble, granite—in a variety of shapes, colors, and sizes.

How Cost Effective is Silca System?

If you have an existing framed deck or are looking at new construction involving any elevated heights, multi-tyres or building over or around obstacles - Silca Systems will save you both time and money.  Typically converting an existing wood or composite deck to a stone deck would involve full demolition, excavation, poring footings and/or sub-slabs, fallowed by full construction of the new stone structure. Based on current pricing, typical Interlock Decking runs between $18-20 per sq ft. When you take into account concrete footings or a sub-slab the price increases to $25-35 per sq ft and these prices do not include the cost of demolition and debris removal.  Silca System will typically run between $10-15 per sq ft, depending on the style of stone you choose and any additional framing that may be required.

What Are Some Of The Advantages Of Using Silca System?

Silca System is an American-made, UV stable product. The durable Silca Grate grids are designed to withstand freezing temperature and the harsh effects of the sun. Unlike deck boards which are known to warp, crack, distort, split, fade, and promote mold/mildew, natural stone and brick pavers are easily maintained and durable. Silca System enables you to install these heavy-duty materials on your deck, eliminating the need for the time-consuming labor and expense of sealing and staining a wooden deck.

How Do You Connect Silca Grates To The Floor Joists?

Center the Silca Grate on the floor joist and fasten down with three-inch deck screws coated for pressure treated lumber. Make sure the screws are placed into the holes at the edge of the grate.  

Is It Easy To Cut Silca Grates?

Yes. For customized cuts around posts, railings or other obstacles, use a circular saw, table saw, jig saw or sawzall.

Can Silca Grates Be Installed Over An Existing Deck Floor?

No. Wood and composite flooring traps water and moisture, creating an environment for mold and mildew. Wood and composite deck boards also warp and distort over a period of time, making an unacceptable surface for proper Silca Grate installation.

How Do You Adhere Pavers To Silca Grate?

Pavers are naturally designed to fit together without moving. Their rough edges, when placed side-by-side, create tension, locking the pavers in place. With that built-in design and the finished edge of your deck, your pavers will remain permanently placed. If you are using polymeric sand between pavers, the sand will harden like concrete, giving you extra insurance that your deck flooring won’t go anywhere. For places where you can’t edge and want to insure that your pavers won’t move, use a construction adhesive.

How Do You Finish The Outside Edge Of The Deck?

You can glue the pavers you used for the deck flooring around the edge, or you can use pressure treated lumber, cedar, composite, or vinyl as edging.

What Makes Silca Grates Structural?

Silca Grates are based on the hexagonally structure of beehives and manufactured from engineered polymers into grids that are 1 ½” thick 

Do Silca Grates Meet Building Codes?

Silca Grate, received an evaluation report ESR# 3748 from ICC Evaluation Service (ICC-ES), providing evidence that the Silca Grate meets code requirements. Building officials, architects, contractors, specifiers, designers and others utilize ICC-ES Evaluation Reports to provide a basis for using or approving Silca Grate in construction projects under the International Building Code.

Can Silca System Be Installed On Roof Tops?

Yes. Silca Grates can be installed in conjunction with Bison Pedestal Products, providing a structural surface for stone, brick pavers, or astro-turf.

Are Silca Grates compatible with Bison Pedestal Products?
