BENTONITE WATERPROOFING COMPOUNDS VOLCLAY PANELS VP1 and VP1F PRODUCT DESCRIPTION Cardboard panels, with differing degrees of biodegradability, filled with granular natural Sodium Bentonite which, in contact with water or simply humidity, turns into an expansive gel that adheres firmly to the structure, effectively waterproofing it. PRODUCT APPLICATION • Protection and waterproofing of underground concrete structures and buildings such as garages, cellars, warehouses, safety vaults, taverns, storage rooms, car parks, underpasses, tunnels etc. against groundwater • Existing tanking structures Contact Volteco Technical Service for a different use. • Easy and quick waterproofing of underground rooms in general • Simple installation by nailing it onto the surface • They can be drilled, cut and shaped to adapt to the structure • They quickly repair damage caused by settling or shrinkage of the concrete • Tanking existing structures How it works When in contact with water, or just simply in contact with the ground humidity, the natural sodium bentonite turns into a waterproof gel through hydration and expands up to 16 times its initial dry volume while remaining in its waterproof gel state. If this expansion is previously contrasted with a concrete casting or a soil surface, this capacity is used to rapidly and independently repair every crack caused by concrete shrinkage or settlement. When in contact with humidity, the biodegradable cardboard deteriorates, thereby allowing the gel to firmly adhere (overlaps seal) and to the structure, making it evenly waterproof. 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 panels must be folded and cut according to the undulations of the cardboard. Transverse cuts must be immediately sealed by wetting the edges of the panel with water. Laying the product on vertical surfaces Remove the formwork spacers by cutting them very close to the wall and plastering them with BENTOSEAL; seal cracks and gravel nests with BENTOSEAL. To seal all accesories with AKTI-VO 201 or WT 102 according to the type and size of the through body.

BENTONITE WATERPROOFING COMPOUNDS VOLCLAY PANELS VP1 and VP1F sections. Start applying the panels from the lower part, overlapping the first vertical row at the fold of the previously applied panels beneath the bed. Stagger the subsequent overlapping rows, paying particular attention to the overlaps. Fasten the panels with nails in the corners and along the overlaps, using the relative Volteco FIX washers. If the panels start from a surface that is not waterproofed, apply the HYDROBAR TUBE curb at the bottom of the panels. Protect VOLCLAY PANELS with 250 g/m² polypropylene spunbound non-woven...
