Hard Court Systems

Hard courts are constructed from a rigid base such as asphalt or concrete. It is critical that these bases be designed and laid to the correct ITF standards which include Size, Planarity and Evenness (please see the links below). The size may vary according to the use, a home court does not need to be full competition size however the evenness (+/- 3mm over 3m for concrete) is a critical factor in all courts. As is the planarity, that is the court must be in a single plane and have approximately a 1% fall. Failure to achieve these standards will result in problems long in to the future.

Sadly in Australia there is no specific legislation that requires engineering to be conducted on a sports or tennis court. However this in no way allows for a “one size fits all” approach. Every site is different and getting a geotechnical report and an engineered design is the cheapest insurance you’ll ever buy. In Australia soils can move from just a few millimetres up to more than 100mm, if the court design does not cater for this, ultimately it will fail and no amount of patching will ever fix it. A properly engineered court should last 40 plus years.

Once the base is correctly designed and laid, there are a range of surfacing options which include

  • Rubber matt cushioned systems
  • These provide a very consistent playing surface (as they are made in factory) and do not go hard over time
  •  In-situ pour rubber cushioned systems
  •  Acrylic paint systems

These are extremely durable, low maintenance and suit all levels of play

Hard-Multipurpose-Court-feature-125122_330x220Each has specific advantages and costs associated with them.

  • With any system it is important to ascertain the “true” quality. Some questions to ask
  •  Is this ITF approved (this demonstrates the manufacturers commitment to the product as it is a costly process).
  • Will the installer show you the warranty before you buy? They aren’t all the same and you need to know what it covers.
  • Has the installer and the manufacturer been in business significantly longer than the warranty period they offer.
  • Can they prove warranties were honoured?
  •  Does the manufacturer train and approve the installers?
  •  Is the product tested for Aussie conditions – our UV levels are nearly double that of Europe or the USA
  • Where is the product made? Aussie jobs are important.

The Products We Use.

In August of 2013 the two strongest brands in the Australian market, Plexi and Rebound Ace combined to form California Sports Surfaces (CSS). As with many mergers the new group is so much stronger than its two former halves. Multisport Concepts is very proud to have been selected to install the entire suite of product from CSS range. Our clients will reap the rewards as we are now able to offer a complete manufacturer based solution to every problem and scenario.


Some things to know.

Fence to Fence or figure 8.

When you request a cushioned hard court system, most of us would expect it to cover the entire court that is “fence to fence”. Be aware of quotes that appear cheap; it has been a practice in some place to install the cushioning in a figure of eight or dog bone pattern covering the baseline areas and narrowing at the net. This isn’t a major issue as long as you know what you’re paying for and compare “apples with apples”.

Coats vs Film build

The paints we use are made up of Resins, pigments, latexes that are dissolved or suspended in a solvent (water mostly). The solvents allow the solid particles to flow and spread evenly. At that point the solvent’s job is done and it evaporates off. Clearly if the amount of solvent in a product is high, then there will be only a small amount of solid particles remaining on the surface. The thickness of the coat of paint when immediately when applied is called “Wet Film Build”, the layer left after drying is called the “Dry Film Build”. The latter being the most important to the end user.

The percentage of these non-solvent components can be very low in some manufactures brands leading to a thin film build. Many of us have experienced this with cheap house paints that require many coats to get a reasonable result.

The easy fix is to “slop” more paint on – of course this simply results in runs on vertical surfaces and issues such as “skinning” and cracking on horizontal surfaces. The next fix is to apply more coats, which is how many brands are sold – 4 coats must be better than 3 … wrong. 4 thin “dry film builds” may not be up to the total thickness of 3 coats of a product with a substantially higher solids continent.

In short it simply comes down to the quality of the product and on that front the California Sports Surface product line is unrivalled. Cracks in Hard Courts

Hard courts crack for several reasons

  •  Ageing in asphalt
  •  Expansion and contraction in both concrete and asphalt
  • Soil movement

Of these the last is by far the most common and severe. Please be very aware that the Building Code of Australia DOES NOT HAVE ANY REQUIREMENTS FOR SPORTS CONSTRUCTION.

A concrete slab can expand and contract by approx. 18mm, soil movements can easily be five or more times that. The very best cure is simply prevention; have a Geotechnical report commissioned (a minimal cost) and have the court engineered. All of the major sporting bodies and any reputable court builder will give this advice.

If you already have a court and the base is cracking, then we can patch and repair with the very best products on the market. However we can’t and no one else can give any guarantee as to how long the repair will last. To quote from the Plexipave web site “When the lineal footage of cracks exceeds 150′-200′ per court, and or the area of the crack interferes with the game, it is time to consider reconstruction, i.e. removal of the pavement or pulverization of the pavement, replacing the net post and adding new pavement, surface and colour.” (150’ to 200’ is approx. 46m to 61m)

Court Care

  • DO keep the surface free of dirt and leaves which can significantly shorten the court life
  • DO remove bird droppings immediately
  • DO use the correct equipment
  • DO NOT use high pressure water blasters to clean the court
  • DO NOT drive maintenance equipment onto the court without protecting the surface
  • DO place pads under equipment or chairs with sharp edges to avoid surface damage
  • DO use non-marking soles on footwear.
  • DO NOT drag heavy objects across the surface.
