Areas of application of our pavement jointing mortars

Using ROMEX® pavement jointing mortars, all types of paved stone and slab surfaces in various areas can be jointed quickly and easily. Whether in the the private sector such as patios, garden paths, driveways or on public roads, pedestrian zones or on market squares. Yearly innumerable surfaces are jointed with our jointing mortar. They are much loved thanks to their easy of application in just a few steps. All ROMEX® pavement jointing mortars are frost and de-icing salt resistant as well as resistant to street sweepers and weed growth.

You are always guaranteed a clean and permanently jointed surface. Worldwide our products contribute to the high quality construction or repair of paved stone surfaces, garden and landscaping and parliament squares and have made their mark on the image of communities.

Private sector

Residential patios and driveways
Pavement jointing mortars are often used on surfaces around the house. It is mainly patios and garden paths that are jointed, in order to permanently prevent weed growth. Synthetic resin pavement jointing mortars are especially liked for use on patios paved with high quality stones. They are not only the best solution agains weeds and ants, but also offer longterm visually attractive surfaces. The classic product for all non trafficked areas around the house is our jointing mortar ROMPOX® - EASY ROMPOX® - EASY. This comes mixed and ready to use and can be easily worked into the at least 5mm wide joints using rubber squeegee or broom. Ideal for all who like to do DIY.

Our 2 component systems offer further possibilities for jointing. If you have joint widths below 3 mm, then you can use ROMPOX® - D1. Thanks to its pouring capability it is most suitable for jointing 3 mm joint widths. We also recommend ROMPOX® - D1 for the jointing of polygonal slabs (also called broken stone or wild form slabs). If large quantities of rainwater need to be dispersed quickly into the ground or if standing water is left after rain showers because it doesn’t drain off quickly enough through the joints, then we recommend our pavement jointing mortar ROMPOX® - DRAIN. This jointing mortar has a water permeability value of 15 l per minute per m² and is the most water permeable one.

If the joints are less than 3 mm wide, which is often the case with concrete stone slabs, then we recommend against using pavement jointing mortar for the joints. In this case we recommend using ROMPOX® - JOINT STRENGTHENER, a special liquid for strengthening sand joints. The joints are filled with dry quartz sand before the joint strengthener is poured into the joints.

In order to prevent weedgrowth on surfaces around the house with higher loads, such as driveways or parking spaces, using our high quality 2 component systems are just the thing. Due to higher compressive strengths and better adhesion to edges compared to 1 component pavement jointing mortars, the systems ROMPOX® - DRAIN and ROMPOX® - D1 are ideal for driveways with traffic loads up to 7,5 t. The highly water permeable pavement jointing mortars allow rainwater to drain away quickly, which communities count as surfaces that are not sealed and thus contribute to environment protection.

Public sector

Residential and public areas
The most commonly planned regulation construction methods are carried out as unbonded or open construction methods according to DIN 18318. Due to ever increasing traffic loads, delivery traffic, weekend and christmas markets, extreme weather effects and the effect of paved stone cleaning using vacuum sweeping machines, the joints disappear and erosion of the entire paved stone surface commences. Each period of frost causes hydraulically bound joints to have weak areas which crack and break out. Longterm the result is empty joints, dislodged paving stones and a damaged surface. A major problem in this is that the surface becomes dangerous to walk on and the risk of accidents for residents and tourists increases.

Thanks to our synthetic resin pavement jointing mortar, frost damage is a thing of the past, as well as unsightly cement residue. With our jointing systems, all your surfaces will be made to look particularly appealing. A further advantage of synthetic resin systems is the quick re-opening to traffic after jointing. In comparison to most hydraulically bound pavement jointing mortars where re-opening to traffic usually only can happen after 28 days, surfaces jointed with our pavement jointing mortar ROMPOX® - D2000 can be re-opened after just 24 hours.

Even surfaces (with an appropriate superstructure) meant for heaviest loads such as bus and lorry traffic can be jointed using our jointing mortar ROMPOX® - TRAFFIC V2, our strongest pavement jointing mortar with a compressive strength of well over 50 N/mm², able to withstand such loads.

Acc. to ATV DIN 18318:2006 the joint widths for gutters should be between 8-12 mm, the paving stone should be set „fresh on fresh“ and jointed using bonded pavement jointing mortar. For jointing gutters made of natural stone or concrete stone paving stones, which drain surface water into the drainage system, we recommend ROMPOX® - D2000. This jointing mortar combines high compressive strength with very good application properties.

Special solutions

Asphalt repair and curbstone repair
Potholes, damaged areas and breakages on curbstones are annoying and a source of risk. For this reason communities are interested in making sure that these occurences are permanently resolved as soon as possible, in winter as well. With ROMPOX® - D4000 HR we have a unique, highly reactive repair mortar, which can be laid even at temperatures of up to -10 degrees Celsius. This means that road maintenance companies can use the product all year round to keep on top of damaged areas and potholes. Thanks to it’s property of high strength mortar system, even broken off curbstones can be permanently repaired.

Repairing old cement joints
Until now, the repair of old paved stone surfaces was limited. Depending on usage and degree of damage to the paved stone surface, the only way was to re-lay the surface as new, which is very expensive. The old joints can be repaired without having to take up and re-lay the paving stones, if the surface is still in good shape and can be walked and driven on. Using ROMPOX® - D3000 it is possible to re-work and repair old cement joints. Narrow joints and cracks in the paved stone surface can also be repaired with this repair mortar. ROMPOX® - D3000 is suitable for joint widths from at least 3 mm and joint depths from at least 10 mm.
