RECOMMENDED SYSTEMS
TECHNO-Swell
Water-swelling rubber based on polychloroprene
- For construction joints in structural, civil and construction engineering
- High chemical resistance against sewage, manure, chemicals aviation fuel (Jet A-1) and deicer
- Integrated pressure limit for small wall dimensions
EQUIPMENT
TECHNO-Swell V
One component, hydrophilic sealing compound for bonding of hydrophilic rubber.
TECHNO-Flex
Mastic adhesive and sealing compound for gluing on moist surfaces and even under water.
TECHNO-Flex Cleaner
For cleaning substrates and for bonding dusts and other contamination.
TECHNO-Flex E
For connection and dilatation joints inside and outside and for permanently elastic sealing.
TECHNO-Flex Primer
For priming heavily absorbent surfaces such as weathered concrete, brickwork, aerated concrete, eternit, natural stone, etc.
USES
Sealing of construction joints
Installation is made in the centre of the reinforcement. Depending on the surface condition, fixing is made by adhering with TECHNO-Flex or TECHNO-Swell V. The sealing of pipe breakthroughs is possible by using TECHNO-Swell circular profiles.
Sealing of precast concrete element joints
The sealing of diafragma joints is possible by using TECHNO-Swell circular profiles. Fitting is carried out by knocking the profile in with a pneumatic hammer. Plugging will be made by sealing with TECHNO-Flex.
Corner areas
In corner areas, the hydrophilic rubber profiles are butt-glued at an angle of 90°. The butt area must be secured by TECHNO-Swell
Connection of profile endings
Connection of profile endings is done by adhesion of parallel bands by means of TECHNO-Swell
Sealing of expansion joints
- TECHNO-Swell circular profiles with a neoprene core are used for the renovation of expansion joints. The profile is knocked into the joint once it has been cleaned out.
- When selecting the profile diameter, ensure that pre-compression is achieved as soon as the profile is knocked in. You must also ensure that the TECHNO-Swell profile is well plugged on all sides (see sketch).
Sealing between old/new concrete elements
- HYDROSEAL box profiles are used to seal between old and new structures against non-pressurised and pressurised water. Fixing of the hydrophilic rubber takes place on the old structural concrete by gluing with TECHNO-Flex and additional fixing with dowels.
- The joint is created using rigid foam panels (19 mm thick) so that the HYDROSEAL profile is concreted in around one third of its depth. Joint sealing is carried out permanently elastically by surface-sealing with TECHNO-Flex E.
Water-swelling rubber for sealing of shaft rings
The main use of AQUA TACKSEAL® is the sealing of shaft rings against in-situ groundwater. Shaft rings can be sealed using both sockets and rebates. AQUA TACKSEAL® functions on one hand like conventional sliding ring seals through compression, and on the other hand creates additional sealing through adhesion and expansion pressure.
Water-swelling rubber for sealing of precast unit shafts
Assimilates automatically to the shape of construction. Adhering on concrete, metal, glass and synthetic materials.
