How-to-Paving-Patio

1 Do It Yourself Or Have It Done By A Professional?

Paving a patio is not necessarily a job for a professional. If you have the right materials and tools on hand and have the necessary manual dexterity and time, you can do this project yourself. To make it as easy as possible for you, we have prepared detailed instructions for paving a patio.

2 Paving a Patio: Step-By-Step Instructions

Important questions to ask yourself before paving a patio:

Which paving stone should decorate my patio? Tips in general about paving a patio we have summarized in our article “Paving a Patio.

What is the current condition / What preliminary work needs to be done?

What laying pattern do I want for paving a patio?

Are all the necessary tools for paving a patio available?

3 Paving a Patio: Important Preparatory Work

To ensure that everything goes smoothly when paving a patio, some preparatory work is needed. Doing this work correctly will also ensure that the patio remains beautiful for a long time and that the ground does not sink and create unsightly deformations.

4 Digging Out The Ground For Paving a Patio

The area to be laid should be excavated by hand or with an excavator. It is recommended to excavate about 40 cm, especially about the frost resistance and winter suitability of the patio (you can read more about what to consider to winterize your patio in our article. Winterizing your patio). These 40 cm are needed for a layer of gravel (about 25 – 30 cm), a layer of grit or sand (about 5 cm), and the paving itself (about 8 cm). Now it is a matter of calculating the right amount of material. This is then ordered from a civil engineering company or another supplier of building materials.

As a rule of thumb, we use the Required amount of gravel = area x 25 cm.

5 Adjacent To The Side Patio

Curbs not only have the function of demarcating the sides of the patio but they are also needed to give stability to the paving. Curbs are available at different heights (25 / 30 / 40 cm) and depths, usually, the stones have a length of 100 cm. Curbs need a solid foundation to be laid.

The height of the foundation depends on the height of the curb. As with the actual paving, it is essential to draw a guideline at the height of the top edge of the curbs. Especially on larger patios, the settlement of the curbs can otherwise get out of alignment very quickly. As a rule, curbs are set before the substructure with crushed stone.

If the patio will later have a privacy screen, it can already be planned here and any supports can be placed immediately.

6 Fill The Patio With Gravel

The area excavated in the last step, where the paving is to be placed, must be carefully compacted. Important note: The gravel should be laid in layers, that is, it should be shaken and compacted after each layer. This increases the strength of the subgrade. The better the layers are shaken, the less likely the pavement will set later. Since compaction makes the aggregate “denser,” you should calculate about 3 inches more ballast height.

Our tip: It is advisable (at least for large patio) to order the truckloads one after the other so that there is always enough time for vibration and the crushed stone – if possible – can be poured directly into the excavated subsoil. This saves you the work of doing this with an excavator.

You have finished placing the ballast when, after compaction, a height of about 11 cm remains from the top of the ballast to the (planned) top of the pavement. This 11 cm is calculated from a layer of grit or sand (about 4 cm) plus the height of the pavers (about 8 cm). When vibrating with the vibratory plate, the pavement sinks another approx. 1 cm. Therefore, the following calculation yields: 4 cm + 8 cm – 1 cm = 11 cm.

7 Crushed Stone Or Sand Bed

The pavement rests on a neatly trowelled bed of fine crushed stone or sand. Which bed material is used depends on local conditions and also on the stones used – the supplier can provide detailed information on this. As a rule, however, the material used also depends on whether the patio is to be permeable or impermeable. Very fine-grained sand barely allows water to permeate, while coarser-grained crushed stone ensures fairly high water permeability.

The sand/chippings are spread evenly over the gravel subgrade with a shovel or wheelbarrow. It is advisable to use a rake to spread the material easily. The layer of bedding material should be about 3 to 4 cm thick; it is then neatly removed with a wooden or a ruler.
