Pavingexpert.com Revisiting GftK vdw 850 Granite Sett Pointing in Hitchin Market Square after 8+ years (in 2017)

This installation including the preparation and application of the vdw 850 was also witnessed and filmed at the time by the PavingExpert team, and this video is also available in this YouTube Channel (NCC Streetscape).

“After 8 years it looks like it was jointed yesterday!” - were the words from Tony and the technical impaction team from PavingExpert.com when they visited to inspect the paving refurbishment that they had last witnessed underway on the site eight years ago, when the traditional granite sett paving of the historic Hitchin Market Square in Hertfordshire, was fully refurbished, and repointed with GftK's vdw 850 Paving Joint Mortar. The expert continues: “Oh yes - The paving had been patched and pointed, re-pointed and grouted, glued and all sorts over the years, but nothing lasted long. They might get a couple of years, but before you knew it, the setts were a rocking and rolling all over again. Faced with the prospect of having to lift and re-lay the whole square, at huge cost, the Local Authority and their Consultants undertook some tests and decided to have one last roll of the dice with what looked like a very promising product: VDW 850 resin jointing mortar by NCC Streetscape. ”Like many old town centres and their market squares around the UK, these are a very demanding environment for paving and particularly the paving pointing. This is due to the more joint-dependent nature of small-format paving, especially with the multiple heavy-duty loadings, from articulated trucks to vans and market stalls selling everything under the sun, plus all sorts of traffic exposure, then frequent cleaning, including with large mechanical street cleaners etc. However, despite this after more than 8 years the paving was looking good - and “like it was jointed yesterday!” – Some testaments to the performance of GftK vdw 850+ from NCC Streetscape.
