Car Park Cleaning Cardiff

Decks, bays, stairs and lobbies are four different problems

• Surface bays collect oil drips, leaf mulch and moss along the edges and islands.
• Multi storey decks carry tyre rubber and dust, and the run-off cannot simply go over the edge or down an open drain.
• Stairwells and lift lobbies are usually about odour and staining rather than dirt, and they need a different chemistry.
• Ramps and pedestrian crossings are the slip-risk areas and the ones an auditor looks at first.

The run-off question on a multi storey

On an upper deck there is nowhere for water to go except the deck drainage, which on many car parks runs to surface water. That means the wash water has to be contained and recovered rather than chased towards a gully. We plan this before quoting: where the falls run, which outlets can be blocked, and how the recovered water leaves site.

It is also why we ask about the deck waterproofing. Some older decks have a coating that high pressure will lift, and finding that out with a lance is expensive.

Keeping the car park open

Almost nobody can close a car park for a day. We work in sections, usually with your coning and signage or ours, taking a bay run at a time and moving as spaces free up. For retail and hospitality that normally means overnight; for an office park, a weekend.

Line markings and signage

Tired thermoplastic markings can lift under pressure, so where the paint is at the end of its life we clean around it and tell you rather than taking it off and leaving you a re-lining bill. If markings are due for renewal anyway, cleaning first and lining after is the right order and we will say so.

Cleaning without closing the car park

Almost nobody can lose their parking for a day. We work a bay run at a time behind coning and signage, moving as spaces free up, so the car park stays open throughout. For retail and hospitality that is normally overnight; for an office park, a weekend.

Deck drainage on an upper level

This is the part that catches people out. On an upper deck the water cannot go over the edge and cannot simply be pushed to the nearest outlet, because most deck drainage runs to surface water. It has to be contained and recovered, so before quoting we work out where the falls run, which outlets can be temporarily blocked and how the recovered water leaves site.

Deck coatings and line markings

Some older decks carry a waterproof coating that high pressure will lift, and tired thermoplastic markings come away with it. Finding either out with a lance is expensive, so we establish what the deck finish is first, and where markings are at the end of their life we clean around them and tell you rather than handing you a re-lining bill.
