Damp Proof Injection Fluid (POAS) - Biokil Crown

Professional-Grade Damp-Proof Injection for Treating Rising Damp in Masonry Walls

Biokil Crown Injection Fluid (POAS) is a highly effective, silicate-free damp-proofing solution designed for pressure or gravity-fed injection into masonry walls affected by rising damp. This ready-to-use potassium oleate/alcohol solution penetrates deeply into porous substrates to create a reliable chemical damp-proof course (DPC), preventing further moisture ingress from the ground. Suitable for use in domestic, commercial, and heritage buildings where traditional DPCs are missing or have failed.

Key Features & Benefits

• Effective Rising Damp Control: Forms a durable DPC within brick, stone, and mortar beds.
• Ready to Use: No dilution or mixing required — ideal for fast application on site.
• Deep Penetration: Reaches into the structure for comprehensive moisture protection.
• For Gravity or Pressure Injection: Compatible with manual and professional DPC systems.
• Low Surface Tension: Ensures even distribution and absorption throughout the wall profile.

Product Details

• Type: Potassium oleate/alcohol-based injection fluid (POAS)
• Form: Clear, ready-to-use liquid
• Application Method: Injection via pressure pump or gravity-fed system
• Suitable Substrates: Brickwork, blockwork, natural stone, and mortar beds
• Typical Usage: Treatment of rising damp in walls up to 600mm thick (or more with dual injection)

Application Instructions

1. Drill Holes: Horizontally drill holes into the mortar bed at the recommended height and spacing (usually 150mm above ground).
2. Inject Fluid: Use gravity or pressure-fed equipment to fill the wall with the fluid until refusal.
3. Allow to Absorb: Let the fluid penetrate fully into the wall before finishing.
4. Replaster: Use a suitable renovating render once the treated wall begins to dry out.

Limitations

• Do not apply to saturated or frozen walls.
• Always use in accordance with current Biokil Crown damp-proofing guidance and local regulations.
