Tank Liners


In response to a rapidly changing world with ever increasing budgetary and environmental constraints, there is a very real requirement to “make do and mend”. By refurbishing existing tanks and bunds, whether they’re made of steel, concrete or plastic, Formatank’s lining systems can provide a cost effective solution to your containment, protection and corrosion problems.


  • Formatank linings provide mechanical strength that will bridge perforations and holes.
  • Refurbishment and repair existing in-situ tanks with little or no disruption to existing plumbing.
  • WRAS approved materials for drinking water tanks.

Surface Preparation

Primary surface preparation aims to remove surface contaminants (i.e. existing perished coatings & bitumen, deteriorated product, rust, and foreign matter).

The effectiveness of any tank coating depends on how thoroughly the substrate has been prepared prior to application. Mechanical adhesion occurs when the coating penetrates rough surfaces, bonding to the substrate by flowing into & filling pores and other surface irregularities.

GRP doesn’t rely on adhesion to a near perfect steel, so surface preparation by means of thorough hand and power tool cleaning as defined in ISO 8501-1:2007 to grade St-2 is generally all that is required in most cases.


A practical and systematic approach is followed in the application of the GRP liner, resulting in a quality product with a nominal thickness of 3mm.

The GRP liner is applied by hand-lay or spray deposit technique using materials specific to requirements. The finished product offers a high impact, chemical and corrosion resistant material capable of accommodating structural movement with a life expectancy of 20 years.
