If you find the top is uneven, add or remove sand as needed to make paving slabs smooth. Place a piece of cardboard between the roller plate and the paving stones to avoid scratching the paving stones. Compact pebbles in the sand. Brush the very coarse sand between the paving stones with a sliding brush.
First, remove the paving stones with the tip of a small flat-blade screwdriver. Gradually pry at the end of each sidewalk. Sometimes the use of two screwdrivers - one on each end of the paver - will help with the swinging process. If the paving stones are close, hit them with a rubber mallet to loosen them.
Build a stone or brick wall at the bottom of the slope. Stack the materials layer by layer. Keep stacking bricks or bricks until your wall is level with the top of the ramp. If necessary, use mortar to fix the wall.
Like all pebbles, lay the paving stones on top of the concrete. Scrape off excess sand and cut off excess landscaping material with a utility knife. Glue the last edge blocks. Let the glue dry for a few hours before emptying the flooring and sweeping the sand across the patio to fill in the joints.
Prevent paving stones from shifting by adding a sturdy border to your patio. You can use a concrete, plastic or metal border. When you’re done, sprinkle fine sand on the decking and sweep it into the crevices to keep the stones in place. You can consider using polymer sand for longer life.
If the paving stones sink, problems with improper compaction of the base material can arise. If it loosens over time, the paving stones can begin to sink. Or it is also possible that not enough gravel was used in the first place.
Laying the paving without sand
Apply a 1-inch layer of sand to the gravel before laying the paving. After laying the pavers, the masonry sand is spread over the entire surface. Photo of sand, gravel and earth outside. Some soil types are particularly sensitive to water retention.
How to Repair Uneven Concrete Driveways
To level the sandy ground of a paved patio:
According to several paver manufacturers, paving stones can be laid on concrete without mortar if you first lay a 1/2 to 1 bed of coarse sand. The procedure is almost identical to the installation of a paved terrace above ground. Before starting, make sure the concrete is well drained and doesn’t itch.
The best way to lay paving stones on concrete
- Build a concrete terrace.
- Incorrect appearance of the stone.
- Be creative with color.
- Place pavers in front of your terrace.
- Color or seal the concrete.
- Set up an outdoor seating area for entertainment.
All types of pavement are suitable for covering an old terrace, as long as the stones fit together and form a dense surface. This includes natural brick, stone or paving. However, if you plan to use mortar, you shouldn’t use bricks if the existing surface is asphalted.
QUICK START: CREATE SHOW BOARDS ON CONCRETE
Determine the slope required for the footbridge size. The slope should be at least 1 inch for each 8-foot patio. For example, a 12-foot bridge needs a 1-inch slope and a 16-foot bridge needs a 2-inch slope.
A deck should move away from the house at a rate of 1/8 (3mm) per foot. In general, a set of 4 (100 mm) thick 2 (50 mm) panels above the floor is suitable. To make sure the height and slope are correct, start digging, planning, and building the formwork where the patio meets the house.
