Heated Driveway News

Keeping Your Driveway Clear of Snow and Ice

I just ventured in from the frozen outdoors. The roads are packed with ice and the trees are laden with frost. My driveway has a rather steep incline, but good traction usually does the trick and allows me to pull up to my home. However, However, ascending my driveway's slope during winter time can often be an adventure. Truth is, my driveway is an ideal candidate for an electric heated driveway snow melting system.

Driveway snowmelt systems are the ticket during winter in any areas that regularly see the icy stuff. Every time you drive over snow you pack it further into dense, slippery ice. How nice would it be to not have that concern? With a radiant heated driveway snowmelt system there is one less thing to have to worry about when you are getting ready to head out in the morning (or pull up to your house in the evening). When morning hits, you get up and look out to discover that it snowed again. Then you look at the driveway and it is as clean as if it were July. You get in your car and drive off. Driveway snow melting has provided us with an easy life. It really wasn’t that long ago when you would have had to break out the snow shovel to clear the way.

A heated driveway system is a big asset in many areas and it isn’t that difficult to install. It will pay for itself in time savings over and over, as well as increase the value of your home. It can even be installed over existing asphalt driveways. Danfoss GX heat cable comes pre-spaced in mats that can be conveniently rolled out over the surface of the driveway. Hot asphalt can be applied directly over the top and vwalah, your icy worries are a thing of the past. Take a look into the many forms of electric radiant heat. You will find systems for virtually every application, both interior and exterior, that can make your life much easier and more comfortable.

Laying the paving – almost done!

This blog the sixth in a series of blogs designed for do-it-yourselfers. This series features step-by-step instructions for building your own heated driveway or patio using brick pavers. The process for building a non-heated driveway is the same (just omit install of heating cables).

Brick paving is laid as ‘flexible paving’ or ‘rigid paving’. The difference is very simple - flexible paving is laid on a bed of sand using sand joints; rigid paving is laid on a bed of mortar using mortar joints. Mortar bedding is used for more sophisticated designs, so for these DIY project, we’ll choose the flexible paving option.

To get started, the first blocks should be positioned from the edge or from outside the pavement area. Setting the first set of bricks is the most difficult part of the paving process and will set the stage for the placement of subsequent blocks. Depending on the pavement pattern you choose, this will be done in a number of different ways. Since we cannot possibly accommodate every kind of pattern and paver type here, let’s start as simply as possible: square pattern.

First things first, take care not to step on the compacted bedding layer by laying the first blocks parallel to the edge. An edge can be set using a taut string line along the perimeter of the paving area. Starting at the edge of the middle and working across, pay attention to the pattern to prevent drifting as you lay each block. Use a rubber mallet to tap blocks into line and keep joints tight.

Shapes of driveways/patios/pathways are not always square shaped with straight edges. Keep your pattern on course and omit blocks on the edges that will require cutting to accommodate varying shapes and curves of the course. Once all the blocks have been laid, the cuts for these blocks will be easily determined and measured. If you are offsetting the blocks, half blocks will need to be cut to fill the edges.

The paving now needs sand jointing, which is best applied by using a broom to brush the sand into the joints, sweep surplus sand off to the side. Compact the paving with the vibrating compactor. The compactor will help the sand settle into the joints, so you'll need to do a second pass of filling the joints with sand and compacting.

Now that you are finished designing and gathering tools, the next step is LAYERS.

Layers. All paving is made up of multiple layers that improve the structural quality of the paving.

Sub-grade is the first layer – the bare raw earth. You will need to reduce the sub-grade to formation level, in other words dig down. As you reduce the layer, keep in mind that you are creating a space deep enough to accommodate not only the brick pavers, but the sub-base as well. Make sure the formation level is as even as possible, removing all high spots and low spots until it mimics the profile of the proposed driveway/patio/pathway. Check for any soft spots that need to be excavated and filled with the harder clay based soil of the formation level.

At this point in the process, many people choose to put down a geotextile separation membrane. This layer has many different names but the goal of the layer is the same: to keep the sub-grade and sub-base layers from mixing and creating settlement. However, a geotextile layer is not needed for every job. If you live in an area with a sub-grade that is dry and firm, you can omit the geotextile layer with a minimal risk of mixing between layers. For sub-grades that are anything less than dry and firm, a geotextile layer can dramatically improve the performance of the completed project. So what is a geotextile layer? Surprisingly, it’s a simple sheet of non-woven fabric.

After the sub-grade layer comes the sub-base.  The sub-base provides flexibility between the sub-grade layer and the base. Although you may not always need a sub-base layer for all patio projects, it is an essential layer in the creation of driveway paving. The biggest cause of settlement and shifting of the base layer is a non-existent or unsatisfactory sub-base layer. Most residential building projects require an unbound sub-base layer such as crushed rock or recycled crushed cement (versus cement-bound and bitumen-bound sub-bases).  The goal is a mixture of larger particles and fine particles (sand) that creates a firm void-free layer.

After spreading the sub-base layer, level it out using spades and finish off with a rake. Next use the vibrating plate compactor to compact the layer and eliminate as many voids as possible.  The sub-grade layer should be between 100-200mm in depth (after the compacting process). To achieve a depth of 150mm, a safe rule of thumb is spreading 200mm depth of non-compacted sub-grade. After the compacting process, the depth will be reduced to 150mm. 

After designing and planning is finished, the next step is gathering proper tools.
