It’s vital to always ensure that you correctly install patio pavers for a more durable and composed finish to your living space. But do I level ground for patio pavers?
Create a plan (diagrammatic representation) of the paving project. Measure the ground accurately before starting the excavation of the area. Pour the Coarse sand (0.5-2.0 mm) or gravel for a depth of about 1-2 inches, compact as you level the ground for pavers installation.
Leveling is an indispensable part of the job when installing pavers on any surface. A level surface not only makes your work easier but also ensures that your paving blocks remain in place for a long time.
Can you lay patio pavers on uneven ground?
Most experts consider an even ground to be essential when laying patio pavers. However, prevailing circumstances such as rocks, tree roots, and so on, might make it difficult for you to have an entirely even surface before installing a patio.
You can lay patio pavers over uneven ground. However, it is not advisable to do that, given the problems that might arise from such a project. It’s crucial to consider the ground topography before deciding on an ideal patio design. Having a poor design can create problems in drainage, aesthetics, durability and limit the practical use of the patio.
Pavers tend to become loose over time. Installing patio pavers on uneven surfaces can cause injuries to young children, old persons, pregnant mothers, and other vulnerable persons who could easily trip over the paving stones.
It’s easy to notice bumps, dips, cracks, and other undesirable consequences after installing paving bricks over an uneven ground surface. The visible imperfections ruin the overall appeal of the construction, and in a house setting, they would diminish the overall value.
Besides, uneven surfaces provide adequate room for weeds and other undesired plants to grow. If your patio floor has several dips, water can quickly accumulate on the indentations giving grass and other weeds a conducive growing environment.
It’s imperative to ensure that you level your ground before laying pavers for your patio. Ideally, you can also talk to a specialist for ideas and suggestions on preparing an uneven surface before laying patio pavers.
How to Level the Ground for Patio Pavers
Having a level ground provides a firm base when laying pavers for your patio. Leveling ground for a backyard chilling spot can be a labor-intensive project that may require more than one person to undertake successfully.
Large patio spaces might require specialized equipment and machinery. If you are working on a small surface, it is also possible to use a few garden tools (such as shovels, rakes, etc.) available at your disposal.
Here are a few steps to consider when leveling the ground for patio pavers
1. Create A Plan for the Project
It’s always a good idea to carefully conduct an extensive assessment of the target area and draw up plans before starting your project.
You can hire the services of a surveyor, architect, and other professions to help you come up with an elaborate plan for your project. You can plan the project yourself if the task isn’t too big (or you want to save some money).
Planning also helps you to keep within your budget limits. You can actively research different designs, prices of materials, etc.
It’s also advisable to create a diagrammatic representation of your project during the planning phase. Diagrams help to build a mental picture of the project and how it will complement the surrounding.
2. Measure the Dimensions
Having accurate dimensions makes it easy to build a quality structure. If the ground is regular shaped, measuring the dimensions is relatively straightforward.
You can use a string and stake to lay out the ideal sections and measurements according to your plan. Measuring dimensions also helps you to make adjustments on uneven ground.
Marking powder helps you to create a two-dimensional view of your patio before construction. It also allows you to identify potential areas of concern that might require more analysis before you can move forward with your project.
3. Excavate the Ground
Ground excavation is an essential part of leveling a paving surface. There is no definite measurement for how deep you have to go when digging for a patio foundation, but there are several considerations that could help you find the model depth.
It’s vital to consider the type of soil within the location of your patio. Clay and other soggy soil types might require deeper digging owing to how it relates to water. It’s also advisable to have a slight gradient on your paving surface to accommodate for proper drainage.
Some experts advise against digging too deep or disturbing the firm underlying floor (common when people decide to use heavy machinery such as tractors). It’s much better to skim over the ground to create a level surface while maintaining the structural integrity of the underlying foundation.
4. Fill Ground with Sand/ Gravel
Sand is a good material commonly used to level paving surfaces. Leveling sand/gravel provides a firm base and creates stability when laying paving blocks.
Coarse sand is better suited for leveling as opposed to fine sand. An ideal sand composition ranges from 0.5mm to 2.0 mm in size. (Which has a much larger size compared to ordinary sand composition).
Some specialists suggest that the ideal depth of sand should be about 1-2 inches. A quick calculation of the dimensions of the patio area coupled with the recommended depth requirements can help you identify the amount of sand needed for the entire project.
When leveling using sand, you need to pour ideal quantities of sand over the intended surface and spread it out evenly. You can use a compactor to make sure the sand levels out on the ground and becomes firm.
Adding sand also prevents your paving blocks from shifting from weight stress or after extended durations. The sand provides good drainage during periods of heavy rain that can help keep your patio durable for a considerable time.
It’s vital to level off the sand before installing pavers on your floor. You can use a long metal pole or a straight board to run across the sand top layer and screed off excess sand.
Make sure to fill in any dips and other indentations on the sand surface before working to lay your patio pavers.
5. Level the Surface
Once you have completed the preparations for the patio foundation development, you can now consider laying your pavers on the leveled surface.
There are numerous designs for you to consider – applying different patterns, types of pavings blocks to use, etc. It’s crucial to work diligently, but don’t rush things. You can also opt for alternative techniques to make your patio floor edges firmer, such as using metal edgings to hold the blocks in place.
It’s also advisable to fill in cracks and other indentations on the paving floor with fine sand as an extra measure against shifting (weak links) between individual blocks.
Can you level pavers after installation?
It is possible to level pavers after installation (although the process can be somewhat cumbersome and tiring).
Poor installation may cause your pavers to become uneven, which can have disastrous consequences for anybody living within your home. Pavers become uneven for several reasons: poor drainage, uneven ground, instances where you did not use correct edging materials, etc.
It’s crucial to identify the prime reasons why your pavers are becoming uneven. (it’s much better to be proactive in your actions instead of constantly patching up the surfaces once the damage occurs).
First, remove the uneven paving blocks. A reinforced surface might be more challenging to work on, but if your patio pavers sit over the sand, a trowel, screwdriver, and other everyday tools might work just fine.
Carefully pry off individual blocks, starting with the one loosely attached to the ground. Work your way across the entire surfaces, use leveling sand to make the ideal adjustments, use a screeding pipe to level and compact the sand before reinstalling your paving blocks one by one. It’s also advisable to tap on the finished pieces gently using a rubber hammer once you are through with the reinstallation.
It’s crucial to make sure that you Lay your pavers on level ground. If not, you might encounter such problems in the future. You should also consider accommodating for drainage, especially if your patio is close to your house. Water can cause your paving stones to sink over time despite having a level surface.
