Decking Systems

Car park decks are constantly exposed to aggressive and corrosive factors such as oil and diesel spills, carbon dioxide gasses, de-icing salts and water, all of which become even more of a problem if cracks already exist in concrete decks.


The use of a deck waterproofing membrane is essential to extend the design life of decking surfaces. Sika’s waterproofing decking systems for car parks go way beyond providing effective waterproof protection, they also provide skid resistance, allow demarcation of parking bays and walkways and enhance aesthetics to create welcoming environments for car park users.

Top Decks & Exposed Areas

Top and exposed decks are amongst the most vulnerable areas of car parks. We offer a range of systems for top decks which offer superb protection against UV attack, water ingress, freeze/thaw cycles and chloride penetration. They have crack bridging capabilities able to withstand structural movement as per design codes.

Intermediate Decks

Although lower decks are not exposed to the weather, they still need protection against de-icing salts, abrasion, impact and other forms of deterioration.


Our systems for intermediate decks offer crack-bridging properties up to -20°C and can positively enhance the appearance of dark environments due to the wide range of colours available.

Protection of Ground Bearing Slabs

We offer a number of protective systems for ground bearing slabs. Able to deal with rising moisture due to damaged or non-existent damp-proof membranes, our range includes vapour permeable systems and Sika® EpoCem® technology for green and damp concrete.


Areas such as ramps and turning circles need heavy duty protection due to mechanical impact and abrasion. We offer a range of tough decking systems for ramps which provide maximum wear resistance and durability.
