Why you should specify SPRA
and how to achieve a successful project
Your objectives
You want the client vision to be delivered on time and on-budget.  During the construction phase you will want to achieve:
  • Effective waterproofing of the roof quickly and early in programme, so that internal fit-out can move ahead.
  • A specialist sub-contractor who understands your project, is safe, organised and requires minimum supervision.
  • A roof system that:
    • Has a good track record.
    • Is compatible with other elements and simple to install.
    • Can be tested for integrity.
    • Is adaptable to late change, for example due to Building Regulations Part L.

Reducing risktraining
 For least risk to your project:
  • Make full use of the product support offered by the SPRA membrane manufacturers.
  • Coordinate roofing and M&E trades by technical collaboration at an early stage.
  • Arrange effective roof protection and clear responsibility for maintaining it until PC.
  • Sequence the work to avoid potentially disruptive following trades such as brickwork or rendering.
  • Check the training credentials of installers.
