Dek-block - Patio and terrace bases
When the time comes to build a new patio or terrace, different methods will determine its size, structure as well as the materials you use. Follow our how-to guide to understand the fundamentals of deck building.

Soil Preparation

Regardless of the type of installation you choose, take into account that proper soil preparation plays a crucial role in ensuring the stability and long-term durability of your patio. It’s very important to solidify the ground by compacting the foundation soil. For maximum density, do not underestimate the amount of compacting material involved. It will serve as the foundation your posts will settle on. Once you’ve dug holes that are deep enough, they must be backfilled to capacity with compact aggregate. This will allow the soil to achieve full strength and support while promoting adequate water drainage. In this part of the country, in the spring, it’s not uncommon for snow to melt quickly during the day and freeze overnight. In order to protect against frost heaving, keep in mind the importance of proper water evacuation. This will help you avoid potential disaster.

Assembling the Structure

Once you’ve decided on a base, our free estimating application provides step-by-step instructions on how to position beams parallel to the house. These beams support the joists which will run perpendicular. Next, anchor your platform to the joists. Your selection of decking material will impact the rest of your patio’s construction. The spacing increments between the joists will also be in function of the materials you choose. You’ll inevitably find that some wood-plastic composites and thinner deck boards require a distance of 12 inches between the joists. Another option is to use pressure-treated wood or cedar decking which can be distributed over joists with 16 inch gaps.

As a result, spacing between the joists will also affect the span of the beams supporting them, and will inform the relative number of blocks or screw piles needed for the foundation. Your choice of foundation type is the underlying factor when planning the layout of your structure. Depending on the materials you choose, you may need to review your measurements and make adjustments.

Rototeck™ Block - An innovative product!

Manufactured by the company with the same name, ultra-durable Rototeck™ Blocks are made from 100% recyclable plastic and are 18 times lighter than regular deck blocks. Developed in 2015, and rigorously tested by an independent engineering firm, Rototeck™ Blocks have a load bearing capacity of 2000 lbs. Rototeck™ Blocks can withstand extreme variances in temperature, thus protecting the structure from damage due to freeze/thaw cycles.

Significantly lighter, each Rototeck™ Block weighs only 2.75 lbs compared to standard 50 lbs deck blocks. This makes them easy to carry and will go a long way in preventing work related injuries. Lightweight, high-performance Rototeck™ Blocks simplify building projects by decreasing the workload, eliminating costs and reducing the overall time you’ll need to invest. Rototeck™ Blocks are an attractive and affordable alternative. Engineered for premium soil gripping, they are impact resistant and weatherproof.

With various technical details to consider, our free estimating application takes the guesswork out of any building project. The proprietary software allows you to explore possibilities as you visualize beams, joists, and decking which you can then recalculate, redraw and customize. The innovative drafting program allows you to experiment with different configurations until you settle on a final plan that meets your budget, before you even get started. 

Ready, set, go have fun and give it a try!
