About our PWR (Penetrating Water Repellent)

Waterstop  Solutions’ PWR treatment can be used on any porous substrate without changing its appearance, to maintain a dry look.

This white spirit-based formulation penetrates deep into the pores and lines them with the product, reducing the pore size so that liquid can longer pass through the substrate, while still allowing it to “breathe”. This can create a water beading “off a duck’s back” effect. This treatment does need to be reapplied, typically every 5-10 years, depending upon the application.


PWR also helps the substrate to effectively self-clean, while also stopping mould and fungal growth and protecting against salt attack and carbonation.




Waterstop Solutions penetrating waterproofing treatments

We employ the latest waterproofing technology in a range of systems applicable to porous substrates, such as concrete, brickwork, mortar or stone.

Depending upon your application, one of these systems may be a more economical option with the added benefits of introducing minimal change to the surface appearance of the original substrate and requiring very low to zero maintenance.

One such water-based treatment is our Hardener Densifier. The hardener densifier treatment reacts with moisture and the free lime or calcium in concrete to permanently improve concrete abrasion resistance, reduce dusting and porosity for easier maintenance, help heal minor static cracks, thus greatly extending the life of aging substrates.


Suitable for a wide range of applications such as:

  • New and remedial waterproofing
  • Dust proofing
  • Reducing mould and dirt build-up
  • Reducing cleaning costs and slip hazards
