Description

Description
Bentorub+ is a green flexible hydrophilic strip of approx. 25 by 20 mm, made of natural sodium bentonite clay and synthetic rubber. Bentorub®+ is manufactured in lengths of approx. 5 metres. The swelling properties are created by the particle structure of the clay. In contact with water and in confined conditions, Bentorub+ will swell to approximately 4V and create a waterproofing pressure inside the joint. The expansive clay mass will thus seal these hair line cracks and voids in the joint. The first expansion is delayed to prevent the strip from reacting too soon with possible rainwater, before or during the installation.

Field of Application
Bentorub+ is designed for sealing construction joints, cold joints and working joints in concrete, around pipe penetrations, in sewer joints, against slurry walls, sheet piling, etc.
Can be used in combination with Infiltra Stop in situations, which are deemed to be high risk.

Advantages
Bentorub+ is a permanently active system, which swells up to approximately 4V.
Bentorub+ is an ecological and user friendly system: simple and quick to install by means of gun nailing or gluing with MS Fixer.
The use of Bentosteel will help the installation and will protect the Bentorub strip against damage during pouring or compaction of the concrete.
The composition of Bentorub+ prevents premature swelling.
Bentorub+ has a proven track record in water treatment plants, water purification plants, underground parking lots, water reservoirs, swimming pools, water tanks, metro works and other concrete structures subject to high water pressure.
Bentorub+ can resist hydrostatic pressures of up to 80 metres of water column = 8 bar.
The durability and performance of the Bentorub+ will exceed the design life of the structure (bentonite is a product of nature).
The highly elastic and plastic properties of Bentorub+ will easily counterbalance the initial concrete shrinkage of the structure.
Bentorub+ can fill small honeycombs.
Bentorub+ will not dissolve in water and is non-polluting
