Hot press GRP sectional tanks

Tank construction

The Balmoral range of sectional GRP tanks may be specified as either externally flanged base (EFB) or internally flanged base (IFB). This allows the use of either flat continuous foundations, close centre beams, pier walls or bearer beams depending upon the type of base required. The internally built tank (IBT) to be supported as standard on an IFB foundation.

The EFB specification is fully self draining allowing ease of maintenance and cleaning.

  • Flexibility of panel sizes allows connections to be agreed on site to suit actual tank location
  • Modular design provides ease of transport and flexibility of assembly on either a prepared flat and level concrete foundation, support walls or bearer beams
  • Panels are rigidly supported by a combination of stainless steel tie rods internally and galvanised box sections externally
  • Installation is carried out by Balmoral approved installers, fully trained to provide total unified responsibility

Base supports

1 Flat foundation

GRP sectional tank base option

For IFB and IBT tanks. Flat screed concrete foundation to be level and not vary more than 2mm p/m or 6mm p/6m, measured laterally or diagonally. Levelling steels are recommended due to difficulties in achieving +/- 2mm per metre over whole base area.

2 Close centre beams

GRP sectional tank base option
IFB and IBT tanks may also be supported by steel bearer beams.

3 Pier walls

GRP sectional tank base option

For EFB tanks allowing self drain. 1m centres required.
