Museum of Zoology Cambridge ASP paving support pads

Achieve stunning finishes

  • Convert unused rooftops and decks into attractive, hard-wearing, useful areas and increase the footprint of your building
  • Cover and protect unattractive waterproofing membranes
  • Allows ground floor patio areas to be made flush with the house without compromising damp course

Universal Paving Pad

Suspended System

  • Raising the paving slabs or decking allows water to drain freely and underneath, so there is no standing water left on the surface. This prevents ponding and associated slip hazards and helps to aerate and ventilate the surface beneath.
  • Unsightly objects such as cables, water pipes and drainage outlets can be hidden underneath paving slabs or decking, improving the aesthetics and optimising the building footprint, bringing increased yield to the developer
install of adjustable height adjustable paving and tile pedestal

Fully Adjustable

  • Achieve millimetre precision with our pedestals
  • Create a flat surface irrespective of imperfections on a slab
  • Cope with falls in more than one direction and accommodate large drops and channels
Adjustable Pedestal Paving Applications

Paving applications

The ingenious headpiece incorporates 4 x positioning lugs (fins) laid out in a crucifix formation set towards the edges of the headpiece:

  • Lugs separate paving slabs and tiles to allow sufficient drainage
  • They create a uniform paving line so the slabs are laid completely straight
  • Being a suspended system, the weight of the slab holds everything in place
  • Rainwater runs between and under the slabs so no standing water is left on the surface making the paved area safer

If you need to support underneath the centre of the slab simply snap off the lugs.

If you do not need lugs and are ordering a large quantity of pedestals we can supply a flat headpiece.

Adjustable height pedestal for decking

Decking applications

The lugs (fins) are set out towards the edges of the headpiece giving a 55mm gap between them. This will house a standard 4″x2″ timber joist between the lugs and decking boards are then fixed to the timber joist frame.

Adjusting the pedestals rather than cutting furrings dramatically speeds up installation.

When laying very large joists, or for areas where a junction of joists occurs, simply snap off the lugs.

If you need to order a large quantity of pedestals without lugs we can supply a flat headpiece.

Have an ultra-low threshold? Try our Minipads range. Our time-saving alternative to fixed height pads and perfect for overlaying and retro-fitting. Available from 10mm to 40mm in just three products:

  • 10-25mm
  • 22-30mm
  • 28-40mm

Product benefits:

  • Achieve precise, split-millimetre accuracy in the height of the pedestal to accommodate tiny changes in the level.
  • Designed for use when working with very tight spaces
  • Thread allows 5mm of change to the level
  • Further 5mm extension plate which is fitted to the bottom of the pedestal
  • 5mm extension plate turns 10-15mm pedestal into a 15-20mm fully adjustable pedestal for use in tight spaces
  • Special handle grips allow installers to adjust the height whilst slab is in situ – saves constantly lifting the slab to change the height

This is our standard range of adjustable supports.

The lugs on our universal head are positionined to accommodate both paving slabs and joists for timber decking.

Height range: 35mm up to 365mm
