Clear stone products can be used in parking areas. This is more of an aesthetic choice or possibly treating a drainage issue. You can use clear stone in a parking area or driveway, however, you will notice that it is noisier with traffic, more difficult to walk on and more susceptible to damage from snow removal than that of a Granular M or Granular A, that has fine particles and binds together.
Paving Stones are a manufactured concrete product and therefore have a very accurate thickness tolerance, allowing for the base layer to be accurately levelled and compacted. Therefore, Granite Screenings are easy to ‘screed’ into a smooth compacted layer and are recommended as the under layer for paving stones.
Although our ½” clear stone (crushed granite) is easier to work with, we do recommend our 1” clear stone (crushed granite). The larger particles will allow for water to flow more freely in drainage areas.
We find all landscapers have their own preferred products and methods. The following is the rationale we use as we are asked this question a lot. On our projects, we typically use ½” clear below a flagstone patio, we do this for a few reasons: 1.) Clear stone does not require compaction and cut flagstone is not always a perfect thickness, and therefore, it normally requires some minor adjustments to the granular layer. Levelling with screenings or Granular M means if the top material is loose, it could compact and result in minor settling. Using clear stone, we find we can set the flagstone with less risk of future settling. 2.) the clear stone offers a drainage layer. 3.) ½” clear is easier to grade and work with than a larger diameter stone below a patio. However, for stair treads, a larger diameter stone is recommended depending on conditions. Drainage is a very important aspect of setting stair treads. If the area is susceptible to water, use larger stone, it will allow for water to flow. We have seen stair treads wash out because of a too-small drainage stone used.
Although, the material recommended depends on the situation, and the larger the product, the better the water will flow. The overall most popular product is 1” clear stone. Larger material such as 2” clear stone is used in some cases with high groundwater flows, but not typical. Smaller materials, such as a ½” clear stone, will drain as well, but water will not move as freely.
All of our quarries are predominantly dark grey in colour. Some quarries have different tones of greys and colours of reds and pinks blended in. The very trained eye can spot a difference but they are all very similar in appearance after application. We do not manufacture or inventory 100% pink granite.
All of our crushed stone products are Granite and manufactured at our local quarries. Granite is a superior product to Limestone. Limestone will breakdown quicker over time, will create a slimy surface when wet and will track into a house. Granite products will not breakdown, go slimy or track as easily.
Decks have open slats that cause drip lines and cause splashing of dirt up against the cladding of a building and windows. Therefore, it is recommended to install geotextile over the sub-base to help prevent weed growth, then a layer of a clear stone product. A crushed ½” crushed granite clear stone or ¾” round natural stone are the recommended products for this application. For each of their advantages, the clear stone crushed granite products bind together better than round particles and therefore do not roll as the round pea stone does. The round pea stone has a more natural, softer appearance, although the small crushed stone looks great and contemporary as well.
