Wood To Stone Deck Conversions

Turn Your Front Porch or Deck Flooring
From Ordinary to Extraordinary

A wood to stone deck conversion has never been easier thanks to products like Silca System® structural underlayment. You now have the ability to construct or renovate your elevated deck or front porch using stone, brick, slate, or other non-wood flooring material.

You can use this system for walkways, patios, stairs, and sidewalks too.

Silca System® is one of our sponsors and we are proud to share their innovative flooring options with you.
Although Mary and I haven't had the opportunity to install this system ourselves, we like the idea of adding elegance and beauty that only stone, slate, or brick can deliver. Learn more about Silca System® below.

Yes, your deck can look this beautiful!

Silca System® allows not only the DIY-Yourselfer, but also contractors, deck and porch builders, and others to create amazing outdoor structures.

Silca System® So simple, yet so ingenious.

Silca Grate ™ (pictured at left) honeycombed designed platforms are sized to fit over standard deck joists and are secured with screws.

Each grid measures 1 1/2 inches and covers 2 square feet.

The hexagonal design ensures maximum strength for both elevated and ground-level decks or porches and other applications as well.

How Does It Work?

New Deck or Porch Construction

The photo below depicts the placement of Silca System® on a new conventionally built deck. Joists are placed on 16" centers upon which the Silca Grates ™ are secured. If adding grout between your stones, bricks, or other materials, place landscape fabric over the grates. Then add your selected flooring material.

Not only do you acquire a sophisticated looking deck or porch, you also minimize maintenance while potentially extending the longevity of your structure.

Resurfacing An Existing Deck or Porch

I've built and resurfaced many decks over the years and believe this is a really neat way to convert an existing deck into a striking outdoor living space.

Simply remove the existing decking material. Follow the general process as outlined above.

You may have to add 2x4 supports to the existing floor joists to support the grates if you have insufficient threshold height (height from the top of your flooring to the bottom of your doorway) as depicted in the photo below.

We like the total versatility of this product. It isn't all or nothing. You can transform all or part of your deck or front porch with this unique structural underlayment.

Perfect for Deck and Porch Steps Too!

First impressions are important. Easily convert your traditional wooden steps to something your friends will envy. Your visitors will be amazed at the beauty of your deck whether it is elevated or not once they set foot on your new stone steps.

Innovative Ideas for Wood to Stone Decks

Walkways, Bridges, and More

Mary and I are also excited to see how easy it is to use for other structures as well. Because of their design it should be easier to use for a variety of projects. Walkways, bridges, patios, and stairs come to mind along with creating platforms for planters, surrounds for mailboxes or other outdoor structures, a patio or work area around a shed, grill pads, and more.

Silca System® for walkways

Use Silca System® technology to create sophisticated and elegant outdoor structures like this garden bridge.

We love this idea and it would have been perfect for us on a previous deck. Use Silca System® technology to create a space for an outdoor fireplace right on your deck. How cozy is that!

Important Planning Considerations for Wood to Stone Decks

We've determined there are several key planning considerations you must apply to your building or renovating porch or deck project.
  • Your deck's infrastructure must be of sufficient strength and free from rot or decay. If remodeling your deck, we recommend you remove the existing flooring material and have it inspected by a building inspector to ensure it complies with local building codes.

  • Carefully consider your stack height and you finished floor height. Include threshold heights in your calculations. If you have sufficient threshold height you will probably be able to attach the grates directly to the tops of your joists. Otherwise, you may have to attach treated 2x4s to the joists as depicted in the photo above.

  • Stack height refers to the total height of your grate plus the material you place on it. For example, the grate is 1 1/2 inches thick and if your brick is 3 inches thick your stack height is 4 1/2 inches. Use your stack height calculation to adjust the height of your flooring around obstacles like thresholds.

  • Use landscaping fabric between the grates and your flooring if you are going to use Polymeric sand between your bricks or stones.

  • Comply with your local building codes. See below for a link to basic deck building codes courtesy of Silca System®
