Grouting of paved areas

Paved areas in public spaces are more than just functional paths – they shape the cityscape and represent safety and accessibility. However, professional grouting and the use of high-quality paving joint mortar are crucial in order to fulfil this responsibility. With austropox^®, you can rely on a durable solution for grouting paved areas that is both functional and visually appealing.

Paving joint mortar HP2:

Factory-adjusted mortar system based on epoxy resin, with special additives and a graded particle size distribution, for grouting and refurbishment of pavings made of concrete, clinker, and natural stone. The mortar system is also used as a highly resilient, drainable and above all fast-hardening bedding mortar in road construction.

Old and inner city areas
Squares, pedestrian and meeting zones
Roundabouts and bus stops
Edge finishes and shoulder trenches
Trenches and drainage channels
Terminals and platforms
Hotel and park facilities
Driveways and terraces

Advantages:

Faster processing enables work to be carried out quickly, thereby avoiding delays.
The rapid hardening of the paving joint mortar ensures that traffic can be allowed through quickly, reducing long closure times.
Shorter road closures minimise disruption to traffic.
The high resistance to de-icing salt and frost ensures that the surfaces can withstand even extreme weather conditions.
High strength and resistance to mechanical stress guarantee a long service life.
Low modulus of elasticity for greater flexibility, which reduces tension.
Resistance to sweepers and high-pressure cleaners facilitates regular cleaning of the surfaces.
Factory-matched materials ensure optimal processing results.
No rewashing necessary, which reduces working time and increases productivity.
The high output per square metre significantly speeds up the grouting of paved areas.

Sustainability:

Ease of maintenance and long-term use

The sustainability of austropox^® paving joint mortar is based on the high quality of the joints, which can withstand extreme loads and forces.

The surfaces are resistant to temperature-related interactions.
The surfaces are completely frost and de-icing salt resistant.
They can withstand high thrust and shear forces (buses, lorries, freight traffic).
Intensive cleaning measures using sweepers do not affect the stability of the joints.
No need to re-sand, as with grit or gravel.
No open joints where dirt, broken glass or cigarettes can accumulate.
The surface remains permanently clean and is easy to maintain.

Environmental considerations when grouting paved surfaces

austropox® paving joint mortar stands for ecological sustainability and environmental friendliness. As a drainable joint, it is water-permeable, which prevents the paving surface from becoming sealed. Instead, rainwater can seep away or evaporate naturally, which improves the local water balance in the long term. This water-permeable construction supports the surrounding vegetation and actively contributes to the preservation of natural vegetation. In addition, the area is used in a heat-sensitive manner, as the moisture provided by evaporation ensures a more balanced microclimate.

Accessibility for all

Furthermore, the permeable paving surface significantly increases the quality of stay. In urban areas in particular, this means an increase in the quality of life for residents and visitors. Sustainability, aesthetics and functionality go hand in hand with austropox®.

Why are sand and grit problematic as jointing materials?

Paved surfaces are subject to enormous stress: in addition to heavy traffic, freeze-thaw cycles, de-icing salt and weather conditions cause the jointing material to wear out quickly. The following problems often occur, especially with unbound jointing of paved surfaces made of sand or grit:

Washing out and leaching:
The loose jointing material is washed away by rain, frost and sweepers.
Risk of tripping and accidents:
Open, deep joints quickly become trip hazards and increase the risk of accidents.
Weed growth and contamination:
Weeds and dirt quickly accumulate in open joints, which detracts from the appearance.
Shifts and settlements:
The loose substructure becomes destabilised, leading to damage and high repair costs in the long term.

Why is cement problematic as a jointing material?

At first glance, cement-based paving joint mortars appear to offer a stable solution. However, they have many disadvantages when it comes to grouting paved surfaces:

Sealing the surface:
Water cannot seep away, which leads to problems with the sewage system.
Frost and de-icing salt damage:
Cement joints are not resistant to freeze-thaw cycles, which leads to spalling and breakage.
Thorough cleaning:
A grey film often remains on the surface, which must be laboriously removed.
High personnel costs:
Processing is time-consuming and results in high labour costs.

HAAS GmbH:

HAAS GmbH develops and produces reactive resins, binders, and high-quality special mortars under the austropox® brand for road, bridge, and infrastructure construction as well as for civil engineering projects.

Our products are based in particular on solvent-free epoxy resins and polymethyl methacrylates. With our production in Austria and our clear commitment to quality, our products stand for reliability and performance. From the motorway to the airport to the central warehouse.

Thanks to our extensive expertise in the field of polymer technology and in the field of fillers, we are able to produce tailor-made systems. The repair systems from austropox® are used in numerous industries and are extremely resistant, abrasion-resistant, 100% frost-resistant and 100% de-icing salt-resistant.
To minimise downtimes, the systems are fast-curing, which means that the surfaces are fully resilient again after only a few minutes to hours.
