Waterproofing with a trafficable wear layer

WATERPROOFING WITH A TRAFFICABLE WEAR LAYER

More and more civil engineers prefer the use of a puncture resistant layer on a watertight skirt as an anti-skid wear layer. This way no other build-up of the road “for instance mastic asphalt” is necessary.

THE BUILD UP OF THE SYSTEM

Treat and prepare the surface.
Apply a primer.

ATTENTION, every substrate requires its own specific primer. A levelling layer can be applied with POLYAC® 55 in case the surface is too rough.

Indien de ondergrond te ruw is kan men opteren om een egaliserende laag te plaatsen met POLYAC® 55.

Put on top of this a 1st waterproofing layer (white or colourless) POLYAC® BDM. This can be the manual version POLYAC® BDM-M or the sprayed version POLYAC® BDM-HD.

Apply after 1 hour (depending on the ambient temperature) a 2nd layer POLYAC® BDM-M or POLYAC® BDM-HD. This layer is always an anti-skid layer. The 2nd layer serves primarily as a protection layer of the 1st waterproofing layer, but also functions as a trafficable wear layer and will be broadcasted with large size granulates.

Ideal for applications on bridges, car park decks, roads, platforms, cycling roads, walking strips, etc.

The colour of the 2nd layer should always be different to that of the 1st layer. This is necessary to guarantee complete coverage of the 1st layer during installation. This will also give you the ability to check over time that the wear layer has not worn off or to determine that the waterproofing layer is still intact and has not been mechanically damaged.

After inspection, the damage can be assessed and any localized repairs can be carried out quite easily. This is all thanks to the unlimited “re-coat” time of the entire system.

Cover the system with a topcoat. POLAYC 61 is a watertight topcoat with excellent adhesion, high mechanical and wear resistance.
