Description

BIGUMA®-1401 is suitable for joints in concrete and asphalt surfaces where there is little or no traffic and which are subject to frequent movement, such as on concrete and steel bridges and along curbs. Thanks to its elastic formulation, it can withstand a potential change in the joint gap width of up to 35 %. In addition, this special joint sealant is characterised by its excellent performance properties at hot and cold temperatures and its good adhesion to mineral and bituminous substrates.

Technical standards: TL Fug-StB, DIN EN 14188-1, Type N1

Advantages

Application instructions

a) Melting

BIGUMA®-1401 has to be heated carefully to the application temperature of 160 – 180 °C in a boiler equipped with mechanical agitation, indirect heating and thermometer. The temperature of the sealant must be thermostatically regulated; it must be controllable at all times. Overheating of the sealant should necessarily be avoided, as this will damage the polymers, which were added for the improvement of the product, and consequently it will lead to a loss of the guaranteed properties.

b) Requirements to the subsoil

The concrete and asphalt joints to be sealed should be thoroughly blown with high-pressure-air or cleaned with a brushing machine, whereas you have to pay attention to special separation of cleaning and application works. For artificial dry-out or pre-heating of the joints, hot compressed air lances can be used.
For BIGUMA®-1401 the primer COLZUMIX®-Haftgrund has to be used, which is adapted to this material. The function of the primer is to bind the dust bonding at the concrete or asphalt and to form an adhesive layer, which will fuse with the sealant being filled into the joints.
The primer must cover the joint flanks completely by forming a film. It is recommendable to prime at both sides a stripe of approx. 1 cm width of the pavement. Before filling the joints the applied primer must have dried, i.e. the surface must be touch-dry. The primed joint has to dry and be free from dust to guarantee an intensive bond to the concrete or the asphalt.

c) Filling of the joints

BIGUMA®-1401 can be applied by can or mechanical by the help of an application lance. The joint sealant must have reached the indicated application temperature during pouring work. If the pouring temperature is clearly below the stated temperature, the flow ability of the sealant suffers. The joint sealants may possibly not fill the to be poured joints completely. There is the danger that voids may occur which later can result in sinking of the sealant under rolling traffic.
Before the application of BIGUMA®-1401 a suitable bedding material is to apply. Through the bedding material the height of the joint sealant in the joint will be modulated. At the same time a leaking of the compound into possibly existing voids and the three-flank bonding will be prevented. A three-flank bonding may lead to a failure of the joint sealant caused by the tension. The cooling of the sealant may cause shrinkage dependent on the joint dimensions; a second pouring can be necessary. This second pouring should be made immediately after the first one. The material has to be poured under flushing.

Weather conditions

The prepared joints are only allowed to be sealed at dry weather conditions and at a surface temperature of the building part of 0 °C.

Material consumption

BIGUMA®-1401: joint length (cm) × joint width (cm) × joint depth (cm) × specific gravity of the sealant (g/cm³) = consumption (g).
Primer: The consumption of the primer (COLZUMIX®-Haftgrund) is approx. 3 % of the sealant amount needed.
