Tips for laying pavers
Below is a summary of the most important points for laying pavers:
1. First of all make sure you have the right base or foundation
You can do this by asking yourself 2 important questions:
- How strong is my existing base?
A weak base may need a heavier or thicker foundation.
- What will my paving be used for?
A driveway requires a more solid base than a garden path. For example, for a driveway you will need a hard base of for example coarse rubble. For a small garden path a base of at least 150 mm of sharp sand is usually sufficient. Sharp sand normally has a slightly coarser grain than ordinary fill sand. It would be best to choose sharp sand with a low lime content, as this will prevent white efflorescence appearing on the pavers. You can spread a layer of no more than 50 mm of crushed sand (coarse sand) over the sharp sand to obtain a more stable base.
2. Choose the right paver
3. Choose the most suitable bond
The strength and aesthetic value of surfacing with pavers are achieved by the way in which the pavers are arranged relative to each other. Depending on the size of the pavers, there are different bonds to choose from. The requirements for a terrace or garden path are of course significantly less demanding than those for a road; but a driveway used by cars or a path used by bicycles would need a stronger bond. Some examples of strong bonds are the herringbone bond and elbow bond. For pathways and terraces a stretcher bond or diagonal bond would be perfectly suitable. When laying the pavers it is also important to have good edge restraints. This will prevent the pavers from sliding.
4. Joint the pavers
Once the pavers have been positioned, it is time to joint them. The best way to do this is with crushed sand or basalt chippings. Crushed sand is a coarse, angular sand that ensures the joints are stable. Basalt chippings have a size of 1 to 3 mm. This makes it harder for weeds to grow between the block paving. Use a broom to sweep the sand or chippings into the joints. Then sweep the paving clean and tamp the pavers into the sand using a plate compactor. Preferably this is equipped with a Teflon or rubber sole, to prevent any damage to the pavers. Once again fill in the joints to the maximum and sweep the pavers clean.
5. Maintenance is not required
If you have selected the correct pavers in the right place and laid them correctly, then they will need very little maintenance. HUWA pavers are also resistant to weather elements such as frost and are not susceptible to chemicals, oil, petrol or grit. If you insist on cleaning your pavers, we strongly advise you not to use a high-pressure washer. You can simply sweep them instead. Preferably use a broom with soft bristles. Any efflorescence can be removed with a brush and water.
