resin installed on block pavers
A recent enquiry from a local Shirebrook resident asking for us to install our resin bonded stone onto his existing pavers caused a bit of a quandary for us. Why? Because this caller had already obtained two quotes for resin installed on block pavers – one for bonded aggregate and one for resin bound and to install on the top of his existing driveway block pavers . When we have enquiries such as this it is necessary to be honest whilst not sounding as though we are criticsing others.
This Shirebrook client has been quoted two completely different prices for resin installed on block pavers ( quite rightly as resin bonded is not the same price as resin bound) but the problem was with regard to the suitability for resin on blocks and in particular when it is for a driveway not being highlighted.
We regularly say that resin installed on block pavers is a no no for a driveway. The porosity for a resin bound installation on to block pavers would generally not be an issue – a permeable surface for a permeable surface, but the very fact that a weight such as a vehicle would be the concern with reflective cracking potentially being as issue for resin installed on block pavers.
An excellent and informative website provides a comprehensive and unbiased report of which the following is an extract.
“The reason for this is that Reflective Cracking is likely to occur with elemental pavements, and this would ruin the appearance, and the performance, of any resin-based system. Although extremely tough, the resin would be liable to crack when loaded unless it is laid over a suitable base” – the website goes on to provide more detail.
Back to resin installed on block pavers if you are using resin bonded this has an additional issue – resin bonded stone is not permeable so the permeability of the pavers below is compromised.
| “Both systems require there to be an existing base to which the resin system can be applied as an overlay. This base, or substrate as it is sometimes known, can be an existing pavement of tarmac, asphalt, concrete or other monolithic material that has been cleaned and prepared, or it can be a newly laid base.The preferred bases vary from product to product, but, in general either bitmac or concrete are preferred because they are “Monolithic”, that is, they are whole, single ‘slabs’ of pavement, with few, if any joints. Accordingly, “elemental” pavings, that is those made from discrete units with joints between each unit, such as block pavers, setts, flags etc., are NOT suitable for use as the base for a resin-based system.Although extremely tough, the resin would be liable to crack when loaded unless it is laid over a suitable base” | |

Reflective Cracking |
Flags and block paving will move slightly under heavier loads such as cars and other vehicles, which can lead to the aforementioned problem of ‘reflective cracking’ – this is the phenomenon where a joint between two separate paving units is transmitted through the covering material, creating cracks and fissures in the surface. |

Resin bonded stone is an increasingly popular product for the commercial and residential sector. Remember because the original requirement for resin was on a commercial leve so it is well above any requirement a residential property would need.
Imprinted concrete, concrete, tarmac we can help. Paths drives or patios. Anti slip and vbirtually weed and maintenance free.
