Grouting new pavement areas
The advantages of grouting with HAAS®
The joint system HAAS® HP2-3K is permanently economical, extending the life cycle of a paved area.
HAAS ® HP2-3K is based on reaction resins, is high-strength, durable storable and is also used in unbound paving construction.
This is the ongoing maintenance cost of a paving area to be greatly reduced.
Also, the fast processing saves a lot of time.
Unbound joints of sand and gravel
The unbound joint material is permanently washed out or sucked out by the influence of the weather and the use of sweeping machines. The resulting deep, open joints are clearly stumbling blocks for the road users and there are always accidents involving personal injury, in which the / the road operator / liability. Furthermore, it comes to very strong weed growth, as well as shifts and subsidence, which can sooner or later lead to total loss of the paved area. The ongoing maintenance costs are enormous.
Joints made of cementitious grout
The bonded joint material, usually cementitious grout, seals the pavement. Surface water can no longer seep and must be discharged into the sewage system. Again a sealed area! Cement joint mortars are considerably burdened by the natural frost-thaw interaction and the use of road salt. After some time, there will be chipping and breakouts of the joints. Also, the processing, especially the cleaning effort after grouting, enormously labor-intensive and time-consuming and leads to ugly gray shades on the surface.
APPLICATION EXAMPLES
You have questions about our product HAAS ® HP2-3K?
Jointing of unbound areas with HAAS®
In the past, the principle was that unbonded construction also requires unbonded grouting because bonded cement mortars are too "rigid" and can not accommodate the unbound area movements, resulting in breakouts of the grout material.
Jointing of bound areas with HAAS®
The installation of a hydraulically setting cement mortar is very laborious and time consuming. The "eternal laundering" after grouting is tedious and is accompanied by unsightly gray shrouds. The better the surface is washed after grouting, the more the quality of the cement decreases.
