Joint Sealants

JOINT SEALANTS

Hot-applied bituminous sealants for permanent sealing of joints and cracks in road pavements. We deliver throughout the Czech Republic and Slovakia.

What joint sealants do

The sealant is melted and poured into the joint, where it permanently bonds with the joint edges. It seals the pavement against water, which slows down degradation of the structure and extends the interval between repairs. It stays flexible even as temperatures change, so it works together with the pavement and does not crack.

Which one to use when

All four are hot-applied bituminous joint sealants. They differ in what the manufacturer intends them for — and in how they are handled on site.

TL-82 — the all-rounder, the only one explicitly for bridges

A plastic-elastic sealant to the TL Fug-StB 01 standard. Intended for sealing joints in new and old pavements, for horizontal and slightly inclined joints in concrete and asphalt. It is the only product in our range explicitly listed for bridging expansion joints of asphalt concrete on bridge structures — with the exception of airport pavements. It tolerates a change in joint width of up to 25 %. Processed at 150–180 °C in a boiler with an agitator and no direct heating; pour above 5 °C and only in dry weather. Density approx. 1.1 g/cm³.

N1 — the most elastic, for frost and large movements

A bituminous sealant modified with polymers to DIN EN 14188-1. The manufacturer positions it as the variant with the highest elasticity: it cites higher elasticity than type N2, better low-temperature behaviour than unmodified sealants, and higher resistance to ageing and UV. It targets bridge structures, roads with heavy traffic and locations exposed to extreme weather swings. Consumption approx. 1.15 t/m³.

N-10 — for the joint between asphalt and paving

The only one in the range for which the manufacturer explicitly lists sealing the joint between asphalt and granite or concrete paving — alongside standard expansion joints in asphalt. Processing at 170–180 °C; a boiler with an oil jacket and thermostat is required — above 180 °C the material degrades. Priming the joint walls is recommended. Consumption approx. 1.3 t/m³ — the highest in the range, so allow for it when ordering.

SB-20 — for rails and dynamic loads

A joint filler (jointing compound) to DIN EN 14188-1. Its speciality: joints around rails — tram tracks — and areas with intensive dynamic loading. It is also used for longitudinal and transverse joints in asphalt pavements and for joints in concrete surfaces. Where the substrate requires priming, a primer coat is recommended for better adhesion to the joint walls.

Where they are used

Expansion joints

Horizontal and slightly inclined joints in concrete and asphalt pavements.

Longitudinal and transverse cracks

Sealing cracks caused by thermal and mechanical stress on the pavement.

Construction joints and tie-ins

Joints between construction layers and the interface of asphalt with concrete or granite paving.

Joints around rails

Tram tracks and areas with intensive dynamic loading — sealant SB-20.
