If all the ground was level, a lot of construction would be easier. Unfortunately, the earth is not flat, so sometimes you have to set up your yard on an uneven surface. There are design techniques to deal with these situations. Brick, concrete, or stone must be laid on all gravel and sand or concrete floors infirm condition. The first thing to do before installing pavers is to evaluate the grounds. Use long boards and levels to determine slopes and valleys. Draw a chart showing the major changes in the area you will be working.

Build trails on uneven ground by adapting to the terrain. Incorporate some slopes – some drips help drainage. Design for major obstacles such as large rocks or deep drops of water. Curved trails can be more visually appealing. Use stairs or terraces on steeper slopes. Construct stairs on steep slopes 1 foot wide and 1 foot high. Create terrace steps with small pitches using long gentle slopes leading to lower steps. Turn the packing material sideways or all the way to secure the step. They must be strong enough to hold the ground. Place individual stiff stones under the slope.
Evaluate the terrain for the courtyard. Make sure the hump is hiding rocks or other hard elements. Check the drips and valleys to see if they are caused by a leaking drain pipe or a natural draining side effect. Depending on the size and other conditions, boulders may be removed, the patio moved away from the patio, or placed in the patio. Replace leaking drain pipe. Divert natural drainage to another area – water must be removed so it must not flow above or below the patio surface. Use a shovel to create wavy depressions in your yard to change drainage patterns.
Keep the walls flat on one side or both sides of the patio on extreme terrain. For extreme slopes, place a retaining wall at the bottom made of paving bricks or blocks and another retaining wall on the opposite side. For moderate pitch, a single wall with grounding on only one side may suffice. Mortar these walls to make them sturdy and support the weight of dirt, foundations, and pavers. If your wall is more than a foot tall, build it step by step from your entry point.
Excavate the paver with a shovel or excavator. Dig 6 inches deep for walks, patios, and other pavements that won’t hold heavyweight. The ramp should dig at least 8 inches and deeper for vehicles capable of handling large boats or other large vehicles. Lay the gravel first, leave it 2 inches wide for walks and patios and set it tight. Use medium gravel, 1/2 to 3/4 inch. Start with large gravel on the highway, then add smaller courses. Finish the floor with at least 2 inches of medium sand. Do not use coarse construction sand or fine masonry sand.
Move a 2″ x 4″ board across the sand base to smooth it out. Shake it from side to side to hold the sand firmly. Layout bricks or blocks in any pattern you like, but always replace seams and gaps. Install flagstone to match the look of your patio. These will be of random width and length. Use a level to make sure the surface is level. Secure it with a rubber mallet.
Finished patio, sanded crevices, or paved surfaces. The use of polymer sand with a binder that seals the joints after wetting is less likely to be infested by weeds and the installation is more robust.
