Patio pavers base,pergola in san diego,glass blocks for landscaping lights - New On 2016

So a few years back we tested all of the available methods and stone types available to us for use as patio base. To force failure, we sprayed an equal amount of water over each pavement, and then immediately drove a small vibratory compactor in a straight line across all four areas.
The number one reason for raised patio failure is improper installation of fill and improper fill material selection. Probably the third most common cause for raised paver patio failure is loss of fill material. The idea is to minimize the amount of material you have to dig, then build a Brock "platform" on which you lay your pavers. In restricted construction zones, such as in areas where storing materials on street is prohibited, where traffic patterns are difficult, or where dump fees are high. Brock PaverBase is engineered for Pedestrian applications, such as patios, paths and walkways.
Note: Expansive or unstable subgrade soil conditions may result in failure of the paver installation including undulations in the finished paver surface or cracking of pavers.
Starting against a straight edge of the patio, lay the Brock panels, ensuring that the side flanges overlap. Once you are done spreading the polymeric or joint sand into the gaps, use a leaf blower to blow the fine dust off the surface of your patio. Once the surface of the patio is completely clean, follow the instructions for wetting on the packaging of the polymeric sand. A long lasting brick patio, driveway, or walkway is the result of a properly installed base. Once the area has been excavated to the right depth and width (excavate wider by however many inches you have in base depth on each side) it’s time to compact the subgrade. Once you have lifted the paver base to the proper height it is important to check for low and high spots.

Notes: It is important that during compaction the entire plate be in contact with paver base material. Landscapers, although this doesn’t apply to everyone of them, can typically install simple patios and hardscape projects, but building a raised patio requires a company that has a tremendous amount of experience installing only hardscape projects to understand what to do and what not to do when building a raised patio. Fill is the material used to fill the void between the bottom of your pavers and the ground. Pea gravel (very small round pieces of gravel) has been used under concrete for years as a base fill material. If you’re familiar with all the general paver installation steps, you know that after the fill material aka the base comes the sand setting bed. Raised patio’s are typically much more labor and material intensive making them more expensive than paver patio’s closer to ground level. Brock PaverBase will not resolve subgrade issues associated with expansive or unstable soils. The 1-2" of Base material should be tightly compacted using a hand tamper or plate compactor. The determining factors include things such as paver thickness and the application of the surface whether it be for pedestrian or vehicular use. In most instances, if you’re building a raised patio, you will be adding a substantial amount of fill material.
However, this doesn’t mean that you don’t have to excavate if your building a raised patio. Brock PaverBase panels will then spread load over that base to help ensure your patio stays level and smooth for years. Subgrade soil issues should be remediated prior to the installation using Brock PaverBase if these soil conditions exist.Brock PaverBase is intended for pedestrian applications and not for vehicular traffic of any kind. By the time you’ve finished reading this post on paver base installation you should know almost everything you need to know about properly installing paver base.

Now there are a lot of advanced factors that can be considered, however, I’m just going to cover the basics and as a rule of thumb should be all that you need to achieve a structurally sound foundation for your paver surface.
An indicator of dry paver base is dry dust being generated during compaction as well as material piles or trails that are created by the sides of the compactor. If a compactor approaches a small low spot, the plate of the compactor will bridge over the low spot and that particular spot may never receive compaction resulting in future settling of the paver surface. In the world of hardscaping (term used to describe the installation of interlocking patios and retaining walls), raised paver patios are among the most difficult installations to pull off successfully. I see it all the time; a contractor builds a raised patio and doesn’t excavate below the frost line and doesn’t remove the top soil. You should always use a geotextile fabric to contain all fill materials when building a raised paver patio.
So to determine the excavation depth we need to know the thickness of the paver and the necessary thickness of paver base.
This will give a pretty good compaction to the subgrade preparing it for the remainder of base to be installed (high clay soils may require additional compacting techniques to achieve prime compaction as clay is compacted by kneading rather than vibrating). This tamping procedure will insure that the maximum amount of sand is holding the pavers in place. If there is limestone 411’s below the concrete or paver driveway but there is pea gravel below the garage floor, the limestone 411’s could work its way into the pea gravel after time. That being said, I HIGHLY recommend that you use a vibrating plate compactor to compact the base especially if you’re building a raised patio.
