Can You Put Patio Stones on Uneven Ground? (How To)

You can put patio stones on uneven ground, but many experts agree that a level ground is much more suited for the job. However, it could be challenging to have a completely level site before installing a patio due to the surrounding conditions, such as boulders, tree stumps, etc.

Before settling on a good patio design, inspecting your selected area’s landscape is critical. To put patio stones on uneven ground, you must first adjust the unevenness and establish a reasonably smooth surface by filling depressions and flattening raised areas. The stones must be positioned on level ground to function correctly and have a pleasant outlook.

Also, to prevent movement of the stones after installation, levelling with bedding sand, crushed gravel, and a spirit level is important.

Should You Put Patio Stones on Uneven Ground?

You shouldn’t put patio stones on uneven ground because the ground may shift over time, and the pavers may eventually break or take on a sunken appearance.

A common problem that can arise from laying patio stones on uneven surfaces is the occurrence of multiple gaps on the patio surface which creates a conducive setting that gives weeds and other unwanted plants enough room to thrive. You can handle this by filling gaps with compacted sand.

What Preparations Do You Need to Install Patio Stones on Uneven Ground?

Tools used for stones

You will need to make these necessary preparations before installing patio stones on uneven ground:

Step 1: Determine the best location for a patio. Check to see whether humps conceal any rocks or other solid objects.

To determine whether dips and valleys are caused by a faulty drainage pipe, or are simply natural drainage depressions, inspect them. Depending on their size and other factors, remove the rocks, relocate the patio so that it is away from them, or include them in the patio.

Step 2: Measure the dimensions. It is simple to construct a high-quality construction with precise proportions. Measuring the dimensions is reasonably simple if the ground is evenly formed.

You will need a stake and string to set out the optimum parts and measurements following your plan. By measuring the dimensions, you can adjust your patio design to fit on uneven ground.

Step 3: Fix drainage issues by first replacing any leaking drain pipes. Then, move the natural drainage to another location. Eliminating the water is necessary to prevent it from flowing over or underneath the patio’s surface. Create swales, or small depressions, with a shovel to alter the yard’s drainage pattern.

Installing patio stones can be achieved by following these simple steps:

Step 1: Mark the Patio Perimeter

To indicate one horizontal line of a walkway, tie a thread to two stakes and bury the stakes. Replicate on the other side. To make curved edges, spread a garden hose across the surface. To draw the lines, sprinkle marking powder or flour over the hose. Use spray paint or turf to indicate curving boundaries if you’d like.

Step 2: Make a Trench

Wherever the walkway or patio will be placed, dig a hole about 10 inches deep. Utilize a shovel for tiny spaces. When moving dirt over more extensive regions, think about hiring a skid-steer loader with a bucket attachment.

To ensure a level trench bottom, adjust the depth of the trench. You can use a carpenter’s or laser level to check for flatness. When required, add or subtract dirt.

Step 3: Add Coarse Gravel

It would be best to place crushed gravel between two and three inches deep in the trench’s base. To level the gravel:

  • Run a plate compactor over it.
  • Use the level to check for uniformity.
  • Avoid using smooth stones since they do not bind together to produce a stable base like the rough edges of crushed stone.

Add two to three more inches of compacted gravel over the previous layer. You can produce a stronger foundation by applying the gravel in two layers rather than all at once.

Step 4: Add Coarse Sand

You should cover the gravel with 2 inches of coarse sand. In the sand, set two small pipes parallel to the outer edge of the sand.

To level the sand in place, move a flat 2-by-4-inch piece of solid wood across the pipes in a to and fro motion. When the sand is flat, gently remove the pipe from the sand while being careful not to disrupt it. Sand should be placed inside the pipe’s depression and evenly distributed.

Step 5: Put Down Patio Stones

On top of the sand, arrange the patio stones in any design you like. In the sand, avoid driving the pavers. If the top surface appears uneven, adjust the level of sand by adding to or removing from it, this will make the patio stones even.

Step 6: Include a Cardboard Piece

To avoid scratching the patio stones, place a piece of cardboard between the stones and the compactor plate. Sand should also be compacted between the stones.

Step 7: Brush With a Push Broom

With a push broom, remove any extra coarse sand from the spaces between the patio stones. You may need to perform this step a few times over a period of 8 weeks following installation.
