7 reasons why you need to use paving pedestals

Conventionally, paving slabs are set into sand, gravel or mortar beds over waterproofing membranes. However, surface water accumulation due to improper drainage can cause the paving layer to sag and deform. This can lead to further damage to the underlying waterproofing membrane. It requires you to replace, align and re-level some or all of the slabs, or repair the waterproofing membrane. The repair and maintenance cost of such a paving system can be prohibitively high.

An alternative method is to use a pedestal system when paving over a membrane. Flooring pedestal systems support the floor for raised paving by sitting between the corners of the paving slabs. They eliminate the need for brick piers or sand and gravel beds and provide a long-lasting solution to flooring needs. Find out more about paving pedestals and their benefits below.

1. Cost-Effective:

Plastic pavement supports are made of polypropylene, which is a low-density thermoplastic polymer. It is much lighter and stronger than most other alternatives, such as brick piers. It is also exponentially more economical to manufacture, install and maintain.

2. Easy installation and maintenance:

Paving with pedestals does not involve sand levelling and concrete fixing, thus expediting the process and making paving work easy.

They allow for even spacing of the paving tiles and distribute the tension evenly on the underlying layer.

By design, the supports allow you to remove the paving slabs easily to access the underlying area for repair. It also drains and protects the underlying waterproofing membrane.

Additionally, installing pedestals does not involve puncturing the waterproof membrane, so its integrity and functionality are retained.

3. Height Adjustable pedestals:

Pedestals, when used with proprietary extenders, can be as tall as 1021 mm. It makes them ideal if you want a level floor, deck or pavement on a 0 to 5% gradient.

4. Prevents Water Damage: 

When pedestals support pavers, the chances of water accumulation are greatly reduced. The raised pavement facilitates easy drainage, preventing water damage from accumulated water, ice and snow.

5. Provides better thermal insulation:

The air circulation between the paver slabs and the substrata also allows for better thermal regulation. The waterproofing membrane will, thus, not undergo extreme expansion and contraction, increasing its longevity. You can prevent damages to both the slabs and the waterproofing membrane.

The air cushion also makes the floor soundproof, ideal for incorporating acoustics in your venue.

6. Eliminates algal growth:

High-quality deck supports made of polypropylene for use in paving over a membrane are mould and algae-resistant. They prevent efflorescence and the growth of algae across the pavement system. Ecologically conscious manufacturers make products out of fully recycled plastic. It is durable and maintenance-free for the rest of its life.

7. Versatile:

Well designed pedestals are highly versatile. They can be used under decks or floors, under pavers, beams or bearers. Applications include paved terraces and walkways, roof gardens, plaza decks, pool areas, and even underwater. They are also ideal for temporary flooring in event venues, and exhibition stands.

They can also be used under various paving materials, including granite, marble, porcelain, and precast concrete.

In summary:

Flooring, paving and decking are challenging aspects of construction with long-lasting implications. If not done well, you end up spending much more on reconstruction and repair works. Consult your flooring and paving specialists to find the appropriate solution for you.
