Model 405 Solinst Flute Blank Liners

Stop Cross-Contamination and Borehole Collapse Before They Start.

Leaving a borehole open between drilling and characterization is a major risk for hydrogeologists. Open holes allow formation fluids to migrate between different geological units, compromising your data and spreading contaminants. The Solinst Flute Blank Liner provides a temporary, fully removable seal that halts vertical flow and stabilizes your borehole the moment drilling is complete.

Unlike traditional grout or bentonite seals, Solinst Flute Blank Liners provide a continuous, high-pressure seal that is entirely non-permanent. You get the protection of a sealed borehole with the freedom to remove the liner at any time for characterization, profiling, or permanent multi-level installation.

Core Benefits for Environmental Professionals

• Eliminate Cross-Flow: Immediately halt the movement of formation water between fractures, preserving the integrity of your site’s natural chemistry.
• Structural Support: The pressurized liner acts as an internal “scaffold,” supporting borehole walls against sloughing, swelling, or total collapse in unstable formations.
• Removable & Clean: Since no permanent materials are used, the borehole remains pristine and ready for future testing or permanent monitoring systems.
• Instant Deployment: Seal your borehole in hours, not days. The eversion process is rapid and requires minimal ancillary equipment.
• No Grout Required: Avoid the time, expense, and permanence of cement or bentonite while still achieving a hydraulic seal that meets strict environmental standards.

Features of the Solinst Flute Blank Liner

• Impermeable Construction: Fabricated from high-strength, polyurethane-coated nylon for a leak-proof, durable barrier.
• Broad Diameter Range: Available in standard and custom sizes ranging from 2″ up to 19″ (50 mm to 48 cm) to fit any drilling project.
• High-Depth Capability: Standard designs are rated for depths up to 425 m (1,400 ft), with custom options available for even deeper applications.
• Versatile Pressurization: Can be everting using air, water, or drilling mud depending on site requirements and borehole depth.
• Chemical Compatibility: Resistant to a wide range of groundwater contaminants; special polyester options are available for remediation injections.
