They can be used for new build or refurbishment projects and are easily cleaned and maintenance-free. Anti-slip grits can be incorporated within the systems to provide slip resistance and surface wear protection and alternatively the membranes are also fully compatible with timber decking, paving slabs or podium finishes.

Polyroof’s range of anti-slip finishes offer an attractive and hard-wearing solution for walkways and balcony flooring. Our standard range of anti-slip finishes is shown below however should you wish to use an alternative grit to achieve a particular aesthetic requirement please call our Technical Team on 0800 801 890 or email technical@polyroof.co.uk

Being maintenance-free and entirely impervious to water, Polyroof membranes are ideal for use with loose-laid timber decking or paving slab systems, such as Caro Pedestal Supports or the Liberty Tiles System. When using timber decking the following points should be noted:

  • Timber decking, slabs or tiles should ideally be loose laid.
  • Timber bearers used with timber decking should not restrict flow of rainwater from the roof.
  • If using the 185, system pre-formed Polyroof GRP reverse right angle trims may be used in lieu of fillet trims where necessary.

Polyroof’s Protec System can be specified as part of a podium roof design, or a “buried membrane” application. There are two types of podium roofs that are commonly used and, depending on which one you chose, the Polyroof specification is tailored to suit.

Decorative Tiles (PU Adhered)


If the specification requires bonded decorative tiles, we recommend the use of Mapei Kerlastic Adhesive, which has been tested and approved for use. This adhesive is flexible enough to accommodate structural expansion movements.

Paving Slabs with Cementitious Mortar


Where cementitious mortars are used additional protection is required to protect from caustic attack, including the use of Polyfinish MMA as a protective barrier and/or a suitable sacrificial layer such as taped polyethylene sheets.

Unique Warm Roof Solution for Balconies

The Polyroof RES Balcony Insulation is an innovative solution specifically designed for warm roof balcony and walkway applications, which eliminates the need for using a plywood deck or mechanical fixings. The system consists of high performance T&G PIR insulation with a 3mm high-strength, non-compressible and puncture-resistant facing board which provides total protection from regular balcony usage.

The boards are coated with the BBA-approved Protec waterproofing system and finished with a durable anti-slip finish to provide a uniquely efficient and effective solution for trafficked warm roof designs.

Key Benefits:

  • High-performance PIR insulation providing excellent thermal conductivity
  • High-strength, puncture resistant and non-compressible facing board bonded to the PIR insulation
  • Boards are directly waterproofed without the need for additional carrier layers or plywood decking
  • Minimises the height of the roof build-up allowing for more flexible designs in terms of upstand thresholds
  • The boards are rot-proof, durable and maintenance-free.
  • Available with bespoke cut-to-falls designs to reduce standing water

Explorer Court, Plymouth

The project included the waterproofing of over 400 square metres on the main barrel roof and lower penthouse balconies for a highly successful and NRFC award winning development by Barratt Homes. The main roof was designed with a wave effect, with an internal radius of 5672mm. For the balcony areas, the designer specified decorative timber decking over the waterproof membrane, which meant that the membrane had to be durable enough to bear the weight from the decking.
