TerraSystem: Water-Permeable Surfaces and Ballast Stabilization

Authorized distributor of German-made TerraSystem binder systems in 24 countries across Türkiye, the Middle East, North Africa and Eurasia.

How is it applied?

The system is laid on site in two layers with standard road construction equipment. Because the stone grains are bonded only at their contact points, water keeps a clear path through every layer.

  1. 1
    Base layer

    Coarse aggregate (from 8/11 mm up to 22/33 mm) is mixed evenly with the binder, spread 10–25 cm thick, levelled and compacted.

  2. 2
    Top layer

    Once the base has hardened, fine aggregate is mixed with the binder and laid 2–4 cm thick in a viscous consistency.

  3. 3
    Compaction

    The top layer is compacted with a smooth-wheel roller, creating a seamless, non-slip and water-permeable surface.

  4. 4
    Opening to use

    With a 25+4 cm build-up, the surface can take full load, including heavy goods traffic, after 24 hours.

TerraSystem — Garden path surfacing

Surfaces that let the rain through

TerraSystem bonds natural stone grains only at their contact points. About 40% of the volume stays open, so rainwater drains straight into the ground instead of pooling on the surface.

  • No drainage gradient or channel system needed

  • No puddles, aquaplaning or spray

  • Seamless, non-slip and easy-to-clean surface

TerraSystem — Application in progress

Two layers, standard road equipment

The system has only two layers: a 10–25 cm base and a 2–4 cm top layer. The aggregate is mixed with the binder, spread and compacted using standard road mixers and pavers.

  • Suitable for heavy goods traffic with a 25 cm base + 4 cm top layer

  • Can be fully loaded after 24 hours

  • Patented production technology; the binder is made in Germany

Made in Germany
TerraSystem — Against desert dust on roads and in cities

Against desert dust on roads and in cities

Sandstorms leave sand hills on roads, cause pollution and reduce driving safety, and cleaning is costly for city administrations. TerraSystem's special binder is sprayed onto the sand and fixes the grains by point bonding.

  • Designed to reduce sand build-up on roads and highways

  • Designed to reduce dust pollution in cities

  • Product development, research and production in Germany

TerraSystem — Pool surround surfacing

From pools to stairs: a wide range of uses

Besides roads, paths and squares, it is used wherever a non-slip, water-permeable surface is needed, even in wet areas. Different colours are possible with natural stone aggregate.

  • Indoor and outdoor pool surrounds

  • Stairs, terraces and balconies

  • Tree discs and landscaped areas

  • Car wash areas and public toilets

TerraSystem — Railway ballast bonding

Ballast stabilization for railways

Epoxy resin is sprayed onto the ballast with a mobile two-component mixing machine. The stones are point-bonded, so the track keeps its drainage capacity and needs less maintenance.

  • Switch areas and transitions between ballasted and slab track

  • Surface bonding against flying ballast and vandalism

  • Easier cleaning at stations and stops

  • Bonded ballast can be recycled and reused

TerraSystem — Application in progress

Strength documented by independent tests

According to a TU Munich research report (No. 2362, 2007), the load-bearing capacity under heavy lorries and forklifts is many times higher than asphalt. The binder's frost and de-icing salt resistance is certified by the Marth engineering office (No. 8307).

  • Tensile strength: base layer min. 13.2 N/mm², top layer min. 12.3 N/mm²

  • No long-term rutting

  • No frost cracking thanks to 40% voids and seamless build-up

TerraSystem — Tree pit surfacing

Environmentally friendly

Unlike asphalt, it does not leach oil or tar. It is water hazard class 0, can be used in water protection areas and needs no special treatment on removal or disposal.

  • Sound-absorbing structure reduces traffic noise

  • Less icing, less winter salting

  • Rainwater returns to the ground, not the sewer

Who is it for?

Municipalities and public bodies

Squares, pavements, parks and tree surrounds; stormwater management and desert dust control.

Contractors and road builders

Road and car park surfaces laid with standard equipment, without drainage channels.

Landscape, architecture and hotel projects

Non-slip, seamless surfaces for pool surrounds, terraces, stairs and garden paths.

Railway operators

Ballast stabilization, transition zones, stations and stops.

Frequently asked questions

How is the price determined?

The price depends on the area (m²), the type of use (pedestrian, vehicle, pool, railway) and the layer thickness. Send us these details and the location, and we will prepare a quote for you.

Which countries do you supply?

Klar Chem is the authorized distributor in these 24 countries: Türkiye, Saudi Arabia, Bahrain, UAE, Iraq, Egypt, Kuwait, Algeria, Morocco, Qatar, Oman, Jordan, Libya, Tunisia, Lebanon, Syria, Russia, Uzbekistan, Kazakhstan, Kyrgyzstan, Azerbaijan, Georgia, Ukraine and Turkmenistan.

Do the pores clog over time?

Standard road cleaning, as with asphalt roads, prevents the pores from clogging, so the surface stays water-permeable.

Is it frost and salt resistant?

Yes. About 40% voids leave room for water to expand as it freezes, and the seamless build-up prevents cracking. The binder's frost and de-icing salt resistance is proven by a test certificate.

When can it be used?

With a 25 cm base and 4 cm top layer, the surface can take full load after 24 hours.
