BENTONITE WATERPROOFING COMPOUNDS VOLGRIP LH - Light PRODUCT DESCRIPTION Bentonite system suited for the definitive protection of reinforced concrete structures against constant or fluctuating groundwater. Its particular self-gripping structure prevents interface transmigration of water phenomena. It is recommended for waterproofing with a water head of no more than 5 m. PRODUCT APPLICATION • Applications with reinforced concrete castings (beds and foundation walls against diaphragms, sheet pile and Berlinese retaining walls, existing foundations or disposable formwork) in constructions such as garages, cellars, warehouses, safety vaults, taverns, stores, multi-storey car parks, underpasses, tunnels etc with hydraulic load of no more than 5 m Contact Volteco Technical Service for a different use. • Easy and quick application • Natural Sodium Bentonite-based product • Insuperable self-confinement • High impermeability • It can be drilled, cut and shaped to adapt to the structure How it works When in contact with water, or just simply in contact with the ground humidity, the natural Sodium Bentonite contained in VOLGRIP LH turns into a waterproof gel through hydration and expands up to 16 times its initial dry volume while remaining waterproof tank to the self-confinement implemented by outdoor non-woven textile. The special VOLGRIP LH needle-punching allows perfect self-confinement in such expansion once the casting is carried out (which is very important to obtain high waterproofing). In fact, the fibres of the non-woven textile (on the external side) protrude purposely from the textile (on the internal side) and during the casting, the fibres are embedded into the concrete, thereby resulting in excellent mechanical adhesion of all the product layers to the structure (not simple superficial adhesion). See the diagram. Through the calibrated mesh of the porous textile, the bentonite gel partially extrudes, thereby guaranteeing the seal of the overlaps and preventing water seepage between VOLGRIP LH and the concrete. This phenomenon also allows the cracks that are normally caused by concrete shrinkage to be self-

BENTONITE WATERPROOFING COMPOUNDS VOLGRIP LH - Light repaired. Surfaces that are to be waterproofed can be damp, not necessarily clean but must not have great protrusions, cavities or continuous water flows that could compromise the self-sealing process of the overlaps. The sheets can be folded and cut in any direction. Laying the product under slabs Level the surface with lean concrete. Apply VOLGRIP LH with the darker textile surface facing upwards, with staggered joints and overlapping the edges by 10 cm. Apply the sheets with FIX 1 or with nails and FIX 5 every 70 cm (approximately)....
