Preparation for a Sloped Driveway
Knowing how to pave a sloped driveway the best way will help give character and definition. The driveway paving process for a driveway that has a slope is not complex as long as you have all the right materials and use proper lay technique.
Excellent preparation either by yourself or chosen paving contractor is necessary before anything else, as it will massively affect the overall outcome. Understanding what type of traffic (heavy, intermediate or low) will frequently be passing to your house should have already been thought out. Next, you need to choose a location for installing a paver on a steep slope; you have to pick the area that comes with the least amount of grade.
It will make levelling the ground and installing the paver a lot easier. You can also expect no unsightly installation or tripping hazards.
When marking out your path, spray paint, stakes, strings, garden hose can be used to mark the edges of the driveway. That way, you can confirm the width much easier visually. It also helps you measure the area to figure out the necessary materials to complete the driveway project and even pave the area more quickly.
Prepare Soil & Ready the Ground
So let’s get started with the building process. First, you have to ensure that the soil under your driveway is well compacted. By doing so, rest assured that you can reduce the chances of sliding down the soil during the installation and driveway usage. This step also provides a stable paver base. Meanwhile, it is advisable to utilize the standard proctor density test, ensuring that the soil beneath the installation area is compacted to 98% or more of the maximum density.
Before making a field samples comparison, you can effectively monitor the compaction by determining the 100% proctor density in a laboratory.
Meanwhile, part of the excavation process is removing roots, rocks, or sods. The surface has to be free from any debris.
You can use a take to ensure that dirt is evenly spread on the exterior. Beware that leaving any large holes causes water build-up underneath the new, paved driveway. If there is build-up, ensure to remove it.
Drainage is found at the bottom of the decline. It is highly critical when dealing since water from the rain may exist. The water picks up more momentum once it travels down the decline.
Take this requirement into consideration, whether you have to incorporate a comprehensive system tying all the downspouts, a sump pump, popups, channel drains, or surface drains to different core outs to the street. When improving the system, you can take advantage of porous geotextile fabric. It also protects the subsoil.
The installation of this fabric also extends beyond the driveway’s edges. Installing the fabric is very easy; unroll and cut it to the required size. Use landscape staples or stakes to secure the fabric. Then, do not forget to use a drainage mat to help prevent water from collecting at the driveway’s bottom.
Sub-Base with Gravel & Compact
Now, it’s time to add the sub-base and gravel. The process of compacting this is very critical in every paver stone installations in driveways. It is essential to be sure the driveway’s integrity and longevity.
That is even more critical if you have to install pavers on a slope because you require an extra layer of precautions. By doing so, you can limit erosion. When tamping down the earth, be sure to use a tamper. This tool also helps in creating a solid foundation.
After the foundation, you need to focus on adding the gravel. Add the coarse gravel or crushed rock down onto the driveway. Ensure that it is approximately two inches deep. Get the rake and spread the gravel evenly. When tamping the crushed rock down, you can use a plate compactor.
Ensure that everything is even while the gravel is compact before adding the pavers.
Install the Pavers
Installing pavers on your takes longer than installing on the ground level. However, all your patience will soon pay off.
In this stage, you have to install the pavers in pattern design. Start by laying out the stones at the driveway’s bottom part. First, you have to install the paver in the middle part of your driveway and then work the way out to the borders, the path’s bottom, and the top layer.
You can use concrete blades for cutting the pavers to ensure they will accommodate the gradient while you are working way up the path. For instance, you try making the pavers narrower as it helps the installation to rise a little bit with the pitch. Don’t worry; the walking surface will remain even.
If you are unsure which pattern you should choose, the safest option is the herringbone pattern. It is ideal for sloped driveways because it interlocks the blocks tightly while reducing the pavers’ chances of shifting horizontally under the weight.
