CAR PARK SURFACE PREPARATION

Surface Preparation Applications

Surface Planing a Car Park

Single & Multi-Storey Car Parks

All car park surfaces will deteriorate over time…

Mechanical abrasion, wear and tear, de-icing salts via water penetration, chemical spills and the action of Ultra Violet radiation from the sun all contribute to deterioration of the surface. Although temporary remedial work may reduce or slow down the effect of these processes, there will come a time when the whole surface may need to be removed and prepared prior to a new surface layer application.

The Specialist Planing Division of SPE Contracting not only have the relevant experience in preparation of car park surfaces – they specialise in them…

Removing Car Park Decks When Surfaces Have Failed

When it comes down to a complete surface renewal, any asphalt layers, protective membranes and waterproofing layers that have failed need to be removed prior to final preparation of the underlying substrate.

In the majority of cases, any surface being removed and prepared is proceed by firstly micro-milling the surface followed by rotary grinding to remove profile (reducing the consumption of resin coatings). Finally, the correct profile required for re-surfacing as achieved through captive methods of shot blasting.

STAGE 1 – MICRO PLANING

The first stage process is to micro plane the car park surface. Skill and care is needed here to remove only the thickness required to remove the old deteriorating deck surface.

STAGE 2 – ROTARY GRINDING

Secondly, we employ rotary grinding to remove any residual surface profile and provide a level surface ready for re-profiling. This technique causes less damage to the underlying surface than other techniques.

STAGE 3 – CLEANING / REMOVING SURFACE DEBRIS

Cleaning is often carried out in conjunction with the rotary grinding process to remove dust and debris as it is created. This maintains a clean working environment and a perfect base for the final preparation stage.

STAGE 4 – SHOT BLASTING

The final stage employs the captive shot blasting process. Here, skilled technicians utilise heavy duty, dust free, ride on shot blasting machines to create the perfect profile as a base for the installation of the new car park deck.

Consideration must be carefully given to the planning and implementation of such projects – will their be weight limitations? Are their access restrictions? What is the best machinery to achieve an optimum and cost effective service? Our highly experienced staff will help guide you through these considerations.
