SCHOMBURG • Rapid and extensive expansion GmbH & Co. KG Detmold • Installation possible independent P-5031/9445 of weather conditions, as the MPA Braunschweig special patented coating delays swelling • Self injecting function by penetration in cracks and voids • Extremely dimensionally stable, does not become tacky even at high temperatures in summer • High inorganic content therefore no material fatigue • Positively supports the self-healing process in work joints through special constituents
Areas of application: AQUAFIN-CJ4 is used for the internal waterproofing of construction joints in concrete structures, which are constantly or temporarily subject to loads due to ground, slope and/or surface water. Use in water exchange zones is straightforward. AQUAFIN-CJ4 is suitable for applications of usage class A, wear classes 1 and 2 in accordance with the technical rules for concrete structures that are impermeable to water, from the German committee for reinforced concrete. AQUAFIN-CJ4 excels with its extensive, rapid and reliable swelling abilities, whereby the factory applied protective coating effectively delays premature swelling from rain.
Advice: • Must be covered by at least 8 cm of concrete. • Always store bentonite waterstops under dry conditions. • Waterstops must lie flat and level on the concrete. There must be no contamination beneath the waterstop. • Before installing the concrete visually inspect the waterstop. Heavily swollen waterstops are unsuitable and must be removed. • Follow current relevant regulations and data sheets. So, for example: - The technical rules for “concrete structures that are impermeable to water” from the German committee for reinforced concrete (DafStb) - The data sheet “injection hose systems and swelling construction joint inserts” from the German concrete and construction technology association (Deutscher Beton- und Bautechnik-Verein e.V.).
Product application: Protect waterstops against slippage and floating away. This is ensured by fixing to the concrete substrate by dowels, nails, plugging or bonding with mounting adhesive for waterstops.
