Nuraply 3PT/3PTM

Nuraply 3PT Tanking System is a positive waterproofing system that is watertight immediately upon installation. Nuraply 3PT and 3PTM are thick and tough, reinforced bituminous waterproofing membranes.

The products work together for waterproofing construction features such as foundations, basements, lift shafts, pits and underslab.

  • Nuraply 3PTM is used underneath the slab with a granular finish to key into the poured concrete
  • Nuraply 3PT is a robust product for waterproofing the vertical walls. It can be welded completely onto the underslab Nuraply 3PTM to fully encapsulate the structure
Key Features
  • Long term and low maintenance waterproofing
  • 20 year warranty
  • Authorised applicators
Scope of Use

Nuraply 3PT(M)systems have been developed for positive long-term, low maintenance waterproofing of construction features such as:

  • Foundations
  • Basements
  • Lift Shafts and pits
  • Underslab

Nuraply 3PT(M) provides a robust watertight solution for areas where water is likely. The system can tolerate some hydrostatic pressure but specific design is required for areas of high hydrostatic pressure such as large building sites by the sea.

Limitations on Use

Not suitable for:

  • Areas where tree roots are prevalent (use Nuraply 3PG instead of 3PT)
  • Situations where the tanking may be damaged mechanically
  • Areas with insufficient room for an applicator to work on the substrate in a safe manner
  • Deep multi-storey basements or areas subject to high hydrostatic pressure without the input of a Nuralite technical specialist
