Pavers, kerbs and setts

Materials used for roadworks are often modular and resistant. These qualities facilitate their reclamation. When dismantled, the materials are transported to the contractor’s stock or to third-party enterprises that take charge of their cleaning, sorting and resale.

Sometimes municipalities, such as the City of Paris, manage their stock of roadworks material themselves. In this context, contractors are required to reclaim and reuse pavers whenever it is suitable, either directly on the same site or via a centralised stock operated by the city. This stock is also where contractors have to procure reclaimed pavers for new developments. In 2015, this centre processed over 4,100 tonnes of reclaimed pavers.

In a context such as Belgium, setts are frequently reclaimed from roadworks. They are thus quite frequent on the local market. In comparison, stone pavements are usually kept in place or reinstalled directly on site (especially in ancient town centres). This type of paving is consequently rarer and more expensive to buy.

As well as pavers, the reclamation market offers kerbs in different types of stones. They often come in different lengths. Kerbs are sometimes reused for other purposes, such as stairs, landscaping features, bollards, etc.

In the Netherlands, clay pavers (Dutch clinkers) are very commonplace and their reuse circuit is highly developed. A study carried out in the Netherlands estimates that clinkers have an average life span of 125 years (and over 250 years for almost 10% of the stock) - which generally exceeds the average life span of a typical roadwork development.

Some reclamation dealers can supply batches of reclaimed concrete pavers, although this product is rarely kept in stock by suppliers due to its low value. When reclaimed it is often for reuse directly on another site.

Common products

Among common products, one can find:

  • Setts (porphyry, granite, sandstone and many other types of stone which often reflect local traditions): they often have a rectangular shape, with a width of a minimum 10 cm and a length between 13 and 15 cm.
  • Stone pavers (sandstone, blue limestone and many other types of stone): they are characterised by a square surface and reduced height.
  • Mosaic stones: smaller and roughly cuboid, they are ideal for laying in a fan shape.
  • Kerbs: in blue limestone, granite, etc.
  • Clay pavers (also known as Dutch clinkers): brown, mauve, yellow, different formats.
  • Concrete pavers: irregular supply.
  • Concrete slabs type 'Stelcon': available only at some dealers but with a stable supply.

Available services

The most commonly available services are:

  • Sawn finish for pavers: stone pavers can be sawn to give a perfectly flat upper surface. This treatment can double the price of the pavers, but provides users with greater comfort in use (for persons with reduced mobility, cyclists, etc.). It must, however, be properly implemented to guarantee this even finish.
  • The pavers are usually sorted (according to size, types, stones) and cleaned (of the remains of mortar, asphalt) by the dealers.
  • Ends of the kerbs: some dealers cut off the ends of the kerbs to facilitate their relaying.

Recorded prices

The prices indicated here are based on observations made in Belgium, the Netherlands or France. They are for professionals and do not include VAT.

  • sorted porphyry setts: 20 to 30 €/m²
  • porphyry pavers, mixture of shape and size: 15 to 20 €/m²

  • concrete clinkers: 4 to 6 €/m²

Specifying reclaimed roadworks material

It is relatively simple to specify reclaimed pavers or kerbs, in either a public or a private tender. Specialist suppliers are used to dealing with large orders. The execution methods are very similar to those for new pavers, but close attention should nevertheless be paid to a series of points:

  • In the specifications, allow for some flexibility in the choice of materials. For example, if a specific format of paver is required, but it is not available on the reclamation market at the time of the work, the supply risks being complicated or expensive, whereas a cheaper batch of a slightly different format could be suitable for the same project.
  • Set out the degree of tolerance in relation to the appearance of the required material in the specifications. Pavers or kerbs with irregularities or traces of asphalt are perfectly suited to certain applications and are less expensive than a 'first choice' product.
  • Take account of the variable length of the kerbs during the design and implementation stages.

Did you know?

Belgium has a special history with porphyry paving. Porphyry paving stones have been massively extracted from the quarries of Quenast and Lessine, two villages located between Brussels and Lille. These sites have produced millions of pavers for both the local and export markets since the 18th century. However, production stopped in the 1970s. Today, it is the reclamation sector that keeps this product in circulation and makes it available for new roadworks. This practice is not exceptional and many public contracting authorities are familiar with the reuse of this material.

The pink granite pavers currently found on the reclamation market in Belgium originate from Swedish quarries. These pavers and kerbs were used as ballast in the holds of the ships sailing between Belgium and Sweden, and they were reused for roadworks once unloaded in the port towns.
