## Product and limitations
GidroBent combines woven and nonwoven geotextiles with sodium bentonite, joined by needle punching. Bentonite needs confinement under concrete or compacted soil. The installation guide covers foundation slabs and underground structures, not all GCL applications. Project and approved work plan take priority. Saline/aggressive water and high pressure require technical review. Batch-specific properties must be confirmed by the quality passport. Do not infer certifications, guarantees, price or performance numbers from example quantities.

The guide's 5.0 kg/m² refers to mat surface mass. A 4 × 30 m roll is an example. Slab overlaps are at least 150 mm longitudinal, 300 mm end; end joints offset at least 600 mm. Guide granule consumption is approximately 0.4 kg per linear metre; approved project requirements govern.
