Test item and field of application
1.1
Test item This General Building Code Test Certificate (abP) applies to the fabrication and use of the „AQUAFIN-CJ3“swelling tape in connection with the „AQUAFIN-CA“ adhesive, or the „Montageschiene/Befestigungsgitter“ of Schomburg GmbH & Co.KG for internal sealing of construction joints in structural elements made from concrete with a high water penetration resistance in accordance with Administrative Provisions – Technical Building Rules, sequential no. C 3.30. The „AQUAFIN-CJ3“ swelling tape is produced in rectangles of 18 mm x 24 mm (width x height).
1.2
Field of application The swelling tape may be used for the internal sealing of construction joints in structural elements made from concrete with a high water penetration resistance, with a maximum opening width of 0.25 mm, against: -
Ground moisture and non-pressing water Pressing water up a maximum water pressure of 1.2 bar (12 m WC) (dimensions 24 mm x 18 mm), The swelling tape is suited for use in zones of frequently changing water levels. The sealing complies with utilisation-class A requirements for application classes 1 and 2 as set forth in the regulations for watertight structures (WU-Richtlinie)1. The swelling tape must be applied as specified in section 4 (Execution). The sealing effect of the tape is based on its ability to swell.

Provisions concerning the construction product
2.1
Composition, properties and characteristics The “AQUAFIN-CJ3” is a swellable Bentonite- and butyl-rubber-based tape. It comes in rolled lengths of 5 metres. For application of the swelling tape to the hardened concrete, either the “AQUAFIN-CA” adhesive (supplied in 290-ml cartridges) is used, or the Montageschiene/Befestigungsgitter (metal rail in 1-metre sections). The construction products have the characteristic values that are shown in table 1 and annexes 1 to 4, which they must comply with.

The fitness for use of the swelling tape as a sealing means for construction joints in structural elements made from concrete with a high water penetration resistance has been demonstrated in accordance with the test principles for certification with General Building Code Test Certificates (abP) for "joint waterproofing elements in structural elements made from concrete with a high water penetration resistance when in contact with the ground" (PG-FBB, Part 1, May 2020). Results are documented in Test Reports No. 5065/1111, No. 5123/7614 and No. 5059/394/13 and No. 1200/063/15a issued by MPA Braunschweig. Construction joints that are sealed with the swelling tape •
provide adequate stability
•
are adequately impervious to water
provide adequate age resistance
for the fields of application mentioned in section 1.2 above. The construction product fulfils the requirements of fire behaviour class E in accordance with DIN EN 13501-1.
2.2

Execution The DBV data sheet “Injection hose systems and swellable inserts for construction joints”, version December 2020 and the manufacturer's installation instructions (Annex 4) apply to the execution and installation work. In the area of the joint, the concrete surface must be dry, even, clean and free of loose components, cement slurry and separating agents. The swelling tape must always be glued to the concrete surface with AQUAFIN-CA adhesive or fastened with the mounting rail/fastening grid. Immediately before concreting, the swelling tape must be checked for a tight fit and premature swelling. The manufacturer is obliged to incorporate the provisions for execution into his processing instructions without contradiction. This general building authority test certificate and the manufacturer's processing instructions must be available at the installation site.

Instructions for installation •
The AQUAFIN-CJ 3 swelling tape has to be stored in a dry place and left in its original packaging until it is used.
The base material must be dry, plane and it must have been freed from loose material, cement slurry and release agents.
To prevent underflow, the swelling tape has to be glued to the base material with the AQUAFIN-CA adhesive applied to its full face, or fixed with the Montageschiene/Befestigungsgitter and the required steel nails / nail plugs (max. spacing: 35 cm). The processing instructions (technical data sheets) for the adhesives must be complied with.
The swelling tape is placed in the middle of the joint, leaving a space of about 8 cm both at the inner and the outer reinforcement. In members of a relatively large thickness, the swelling tape can be installed within 1/3 d to 1/2 d of the member thickness d (with respect to the exposed side).
In joint areas, ends are abutted and firmly pressed together.
The swelling tape has to be checked for perfect fit and premature swelling before placing the concrete.
Due regard must be given to the regulations in DIN EN 1992, DIN 1045, the regulations for watertight structures (WU-Richtlinie), and DBV codes of practice (DBV-Merkblätter) in designing and providing joints.
