BENTOTELO

Bentonite-based waterproofing product

Manufacturer DIASEN

Bentonite and self-sealing geo-compound, made of natural sodic bentonite, pre-treated with the addition of special additives and adhesives, active also in presence of waters with high hardness or with high level of contaminated elements. ADVANTAGES • High tear resistance • Easy application • Quick application • Easy maintenance USES All the application in containment works where are required low hydraulic conductivity, stability during the time, lastingness, easy application, self-sealing overlaps and power of self-healing. APPLICATION SETTING OF THE SURFACE Concrete bed For the horizontal laying, it is necessary a layer of concrete (lean concrete as cleaning) to realize a uniform base where create the geo-synthetic bentonite barrier. Thickness must not be lower than 10 cm on the whole surface. Walls of foundation To waterproof the vertical wall of foundation (post-concrete casting waterproofing), it is necessary to remove all the roughness. Eliminate any hollow by smoothing with fibre-reinforced cement mortar. Partition To waterproof vertical concrete partition wall (pre-concrete casting waterproofing), it is necessary to realize a uniform base with neither roughness nor hollows. All roughness must be removed. Hollows must be eliminated by smoothing with fibre-reinforced anti-shrinkage mortar. BARRIER LAYING Horizontal laying In horizontal applications, lay the rolls by spreading the polypropylene geo-fabric (black sheet) downward, so toward the lean concrete as cleaning; polyester geo-fabric (white non-woven) must be upward and so visible. Cloths must be lay, “spreading” them on the lean concrete, avoiding to create traction tension by an extreme speed in laying the mechanical mean used. Likewise, it is necessary to avoid folds caused by a wrong spreading of the barrier. On the joint with the foundation wall, Bentotelo® must be spread till the wall and then covered with a pannel Vertical laying On vertical application, post-concrete casting, lay the rolls from up to down, spreading polyester geo-fabric (white non-woven) in contact with the vertical structure to be protected (foundation wall); polypropylene geo-fabric (black fabric) must be turned outward and so be visible. During the filling up, the black geo-fabric will be in contact with the ground. OVERLAPS SETTING Apply BENTOTELO®LARGE in such a way to guarantee the following minimum overlapping between contiguous sheets. minimum of 20 cm for longitudinal overlaps (overlap realized in the same direction of rolls unrolling) minimum of 40 cm for transversal overlaps (those top/top between two rolls, or by the short side of the roll). Apply BENTOTELO®MEDIUM in such a way to guarantee the following minimum values of overlap between contiguous sheets. minimum of 15 cm for longitudinal overlaps (overlap realized in the same direction of rols unrolling) minimum of 30 cm for transversal overlaps (those top/top between two rolls, or by the short side of the roll). Apply BENTOTELO® SMALL in such a way to guarantee the following minimum values of overlap between contiguous sheets: minimum of 10 cm for longitudinal overlaps (overlap realized in the same direction of rolls unrolling) minimum of 20 cm for transversal overlaps (those top/top between two rolls, or by the short side of the roll). Transversal overlaps (small side) should be staggered of , during the horizontal application, not lined with a minimum of 50 cm in the unrolling direction. STORAGE Keep rolls in a cover, clean and dry environment, avoiding direct contact with the ground. It can be used wooden pallet, taking care to assure an uniform contact between rolls and support. If there is not a cover space to store the rolls, it is necessary to cover them by a polyethylene sheet TECHNICAL DATA Bentonite Natural sodic granular Bentonite content 5,0 kg/m2 minimum Water permeability coefficient (DIN 18130) < 1E-11 m/s Static punching (EN ISO 12236) > 2250 N Resistance to tensil stress – longitudinal (EN ISO 10319) > 15,0 kN/m Deformation with max load – longitudinal (EN ISO 10319) < 20 % Traction resistance – transversal (EN ISO 10319) > 15,0 kN/m Deformation with max load – transversal (EN ISO 10319) < 15 % Overlaps adhesion The geo-compound is self-sealing
