Maintenance Tips for Long-Lasting Paving Stone Pedestal Installations

It is no secret that topping pedestals with paving stones is a time-tested and aesthetically pleasing method to form elevated surfaces over rooftops, terraces, patios and pool decks. The modular nature of their construction has excellent drainage, stability and flexibility. But in order to keep your paving stone pedestal system looking and enhancing your outdoor space for years to come, regular maintenance will be required. Here are some practical tips to help make your installation last longer.

Regular Inspection is Key

Regular checks may identify the small issues early on before they become major – and majorly expensive – problems. Look for indications of movement, such as differences in elevation, or the movement of tiles, or if the tiles have become wobbly, as they could indicate that the pedestals have shifted or the base has settled. Occasionally, look beneath the pavers and inspect the pedestals for any cracks that may have developed due to pressure or environmental stress. Keeping levelling flat and straight will not only help with levelling but also keeping the structure sound.

Keep the Surface Clean

Soil, moss, and other natural debris may accumulate over time that hold moisture or cause stains. “Regular cleaning of the surface of paving-stone pedestals with a mild-pressure water wash or stiff broom will help to ensure that the area remains safe and attractive looking,” says Vrolyk. Avoid using strong chemicals, or acidic cleansers which can damage the stone or pedestal material.

Maintain Proper Drainage

Efficient water drainage is one of the main benefits to having pavement stone pedestals. But if leaves, detritus or sediment fall into the paver joints and clog them, water can pool up and damage the foundation below. Keep the spaces clear and check the underground system to make sure it is working properly. In rooftop applications, cleaning scuppers and weep holes is crucial.

Check for Freeze-Thaw Damage

In cold climates, both pavers and pedestals can be put under additional strain if they are exposed to a freeze-thaw cycle. Water pooling under the stones and then freezing could expand and push lifting or breaking. Make sure the pavers and joints are sealed correctly (if they are supposed to be) and shovel off the snow sooner than later. Use salt and de-icing chemicals with care, which can cause natural stone and pedestal elements to deteriorate or discolour.

Level and Re-Level as Often as Necessary

As the years pass, expansion and contraction of the pavers from freeze/thaw cycles or structural changes can cause pavers to become uneven. Pedestal systems available today can be adjusted, and are capable of re-levelling without dissembling the entire paved surface. Regular re-adjustments allow for continued usefulness and appearance, especially in high use areas where wear and settlement is more common.

Protect Edges and Transitions

Paver Pedestal System Since edges and transitions in a paving stone pedestal system are not, the units tend to wear and become loose. Utilize appropriate edge restraints or perimeter trims to keep the final row of pavers in place and help prevent lateral movement. In heavy-traffic zones, adding more pedestals or adhesive on these areas would be helpful for locking stability and prolonging the service life of the system.

Conclusion

Paving stone pedestals don’t require much work, but they do need regular attention and a do-it-now mentality. By checking the installation, cleaning it, and maintaining its proper drainage in addition to some small timely repairs, you can extend the life of your paving stone pedestal installations.
