A large part of annual new paving would not be necessary by timely joint renovations.
The service life of many paved areas would increase many times over and, of course, also the cost-effectiveness. In general, the sooner the maintenance and repair of the joints begins, the more efficient the overall maintenance and total cost of a paved area.
Damaged joints

Damaged joints -
what will happen?

In most paved areas, in particular
in heavily loaded areas such as roundabouts, bus stops or pedestrian areas, frost-thaw interactions, de-icing salt and enormous shear and shear forces destroy the joint material.

Broken joint material sooner or later leads to a temporary and pre-mature effect All costly total loss.

The stones become loose, surface water, frost and de-icing solutions penetrate into the superstructure and dangerous subsidence occurs, which represents a great risk of accidents for all road users.

Renovation with HAAS®

Why a rehabilitation
with HAAS® works well

The advantage lies in the fact that HAAS HP3-3K - in contrast to cementitious grout - adheres from a very small joint depth and expires on grain size or "to zero".

The joint system HAAS HP3-3K is high-strength, absolutely frost- and de-icing salt-resistant, sweeper- and high-pressure cleaner-resistant and fully loadable after a short time. Another significant advantage is the faster processability compared to cement-based mortars.

The rehabilitated area no longer needs to be extensively aftertreated and washed, which makes it possible to achieve an extremely large square footage.

Renovation with cement

Why a rehabilitation with cement does not work

As every street-conserving institution usually knows from personal experience, joint repairs with cementitious or hydraulically setting grout are not effective because the old joints can not be completely removed and thus the existing joint depths are insufficient for maintenance with cement joint mortar.

Furthermore, the paving process is timeconsuming due to the complex post-treatment or the washing of the bricks, which leads to high personnel costs.

Experience has also shown that surfaces renovated with cement need to be recontoured almost every year ,
