Boode BGP™ - Gravel Coated PVC Screen

Boode BGP is a gravel-coated PVC screen for water well installations in areas where suitable gravel packs are not readily available, but a sand-free water supply is essential, where multiple aquifers are targeted or where installations are very deep and a filter pack needs to be correctly & accurately placed.
 

Ideal for the rehabilitation of damaged or corroded wells or where a smaller diameter borehole is required.

There is virtually no permeability loss as the powerful waterproof bonding replaces normal capillary retention. The gravel coating consists of carefully selected, uniform silica gravel (>98,6% SiO2).
 

BGP Screen is available in diameters from 33mm to 400 mm.


 

 

Advantages of Boode BGP Screens

  • Uniform gravel coat ensures 100% coverage.
  • Excellent sand control
  • Recommended for rehabilitating damaged or corroded wells.
  • Ideal where a smaller diameter borehole is required
  • Increased collapse resistance
