Stormwater Drainage Products and Systems

Thinking of building a new home or commercial property?

Have you thought about how you will deal with storm water drainage?

Most people never give a thought to the potentially damaging amounts of storm water runoff that sometimes occurs on their properties...

...that is until there are flooding or erosion issues.

But the problems of dealing with the water that runs off your roof, driveway, footpaths, and patio are complex.

In the good old days simple pipes and culverts drained the water containing leaf litter, oils and other pollutants from your property to where it was eventually dumped untreated into a river or the ocean.

It was effective but it simply transferred the problems elsewhere.

Stormwater Flooding

Modern Stormwater Drainage Systems

The massive increase of in-fill housing, large commercial areas of sealed impervious land cover preventing natural drainage, and water shortages have forced councils and government to find better solutions for dealing with storm water.

The result?

Lots and lots of rules and regulations.

But seriously, modern storm water system designs are much more effective at draining the water, reducing flooding and erosion problems and recycling water runoff for non-potable uses such as watering the garden.

With global warming and the likelihood of increasingly severe storm events it pays to design a really effective storm water system for your new or existing building.

And with the right people on your team it doesn’t need to be a sinkhole for your money.

Stormwater Drainage Design

Modern storm water design focuses on three important areas:

  • Slowing down water flow to reduce flooding or erosion problems downstream 
  • Retaining water on the property for use in gardens as a natural filtration system 
  • Reducing the cost of cleaning and unblocking storm water drains

Expert advice, design and installation are critical to the success of your storm water drainage and are pivotal to keeping your project within the budget.

Some aspects that you will need to consider in your design include:

  • Soil type and depth 
  • Depth of the water table 
  • Slope aspect of the land 
  • Council regulations

At No 1 Roofing supplies we can offer expertise built on experience and a wide range of products to suit even the most challenging situations.

Drainage Pits

Intense rain events and large roof collection areas can lead to enormous quantities of water coming through the downpipes in a very short space of time.

One of the major storm water problems occurs when that water hits the ground; the sheer speed and volume of water can overwhelm standard sized piping and cause flooding.

A similar water volume problem can occur when you have a large surface area such as a sealed commercial car park; in severe storm events the water simply cannot drain away fast enough.

Drainage pits can retain a large volume of water slowing it down and releasing it gradually and harmlessly into the storm water system.

We can supply a wide range of drainage pits and grates including:

  • Reln - uses 100% recycled plastic to create super tough and environmentally friendly drainage pits in a range of sizes and depths and able to cope with up to 175 litres of water and withstand ordinary vehicle traffic. Solid cast aluminium grates in a range of colours make for a perfect finish. 
  • Mascot Engineering Pits & Grates - glass reinforced concrete pits to all sizes and load ratings. Benefits include flexible conduit entry points, impressive strength to weight ratio, and beneficial for the environment (40% less environmental impact than traditional concrete). Matching cast iron or galvanised steel grates are available. 
  • ACO polycrete - drainage pits and risers are made from acid and chemical resistant polymer concrete. From homes to airports ACO polycrete manufactures the right drainage system for your needs along with stainless or galvanised steel grates. 
  • Wilmac - a big range of concrete pits and risers and various litter screens and grates designed for every situation.

The grates are designed for easy removal allowing for a straightforward cleaning process.

All these companies are Australian owned--we’re proud to support Australian made.

Stormwater Grates

Storm water grates and mesh screens play a key role in managing excess water runoff.

Principally, they restrict leaf litter, trash and other objects from going into the drains and clogging up pipes.

But they also provide a safe surface for the passage of people and vehicles and so their design needs to balance up a number of key factors:

  • Load rating—how much weight will the grate have to bear? Will the grate need to withstand the weight of cars and trucks or only the weight of pedestrians? 
  • Aperture size—the holes need to be small enough to prevent leaves and litter from clogging up a drain but not so small that there is insufficient water flow to cater for heavy rain events. 
  • Aperture shape and size may also need to cater for cyclists, wheelchair users, and high heels and we have grate designs specifically targeted to the safety of these users.

Clearing and cleaning your drains is so easy with these click to fit/ quick to clean grates.

Beautify Your Home and Enhance Your Investment with Architectural Panels

Architectural Panels

Renovations and new home builds can make your home stand out from the crowd – if you choose the right materials.

In Sydney, homeowners are spoilt for choice when it comes to renovations.

Whether it’s the facade, landscaping or fashionable interiors, design is limited only by imagination and budget.

First impressions matter the most.

So it’s no surprise many homeowners are ditching the red brick and tile and opting for a stylish roof, smooth rendered walls or perfectly aligned cladding.

‘‘People are more aware of the exterior of their house than ever before,’’ says roofing expert David Scali. ‘They want their house to be a feature ... they want people to see their house and say, ‘Wow, that’s awesome’.’’
Architectural Panels Snapline 45 in Colorbond 1

Australian roofing trends have come a long way since the days of basic shingles and tiles.

Renovators tend to go for metal roofing and wall cladding, a trend inspired by European and American design looks.

‘‘Metal gives architects much more scope – much lower pitches, more shapes, curves, all these things can be achieved with metal which is not really able to be achieved with tile,’’

...says Scali, who runs No.1 Roofing and Building Supplies, an independent manufacturer, wholesaler and retailer.

Architectural panels made from Colorbond, Zincalume and aluminium have become popular in modern Australian home design.

In the trade they are known as standing seam, snap lock, interlocking panels and nail strip and Snapline 45.

The panels either fit with a concealed direct fix screw or clip system.

They give a clean line and flat pan look.

Colorbond is the most popular choice for panels and it comes in a range of colours, with more options than traditional tiles and older-style corrugated roofing.

The trend is to go matt, not gloss.Thanks to technology, Colorbond roofs also fade less than they did in the past, making metal ‘‘very low maintenance’’, Scali says.‘

Roofing Snap Lock
Cladding Snap Lock

‘You probably wouldn’t have to repaint a Colorbond roof until the end of its lifespan most of the time now, whereas people used to do it quite a bit,’’ he says, adding that a roof can have a lifespan of up to 50 years.

The trend to metal roofs is also driven by insurance companies.

Metal is seen as more hardy than tiles. Tile roofs tend to crack and leak in violent storms.

Metal better withstands hail and bad weather.

‘‘Extreme conditions can damage any roof but a metal roof will generally handle poor weather better than a tile roof, including branches falling on it,’’ Scali says.

Architectural panels can be more expensive than traditional roofs.

But, Scali says, from what he has seen, they can add hundreds of thousands to the sale price of a property.

‘‘People may overlook it a bit, but a lot of prospective buyers will actually look at a roof,’’ he says.‘‘

There is definitely value in a new roof – it really highlights a house.’’

Climaseal 5 Roofing Screws for a Longer Lasting Roof

Climaseal 5 Roofing Screws for a Longer Lasting Roof

In roofing construction, as in life, it’s often the little things that can really let you down.

Fortunately, Climaseal anti corrosion screws and fasteners can make all the difference to your roof.

We all know that corrosion is a major problem for roofs in Australia but did you know that using the incorrect roof screws could lead to the complete failure of your roof?

Trying to save some money by using inferior screws is a recipe for disaster.

Using the wrong screw can actually speed up the corrosion process due to:

  • Galvanic corrosion—the wrong screw may actually set up a galvanic reaction with your roofing material and accelerate the corrosion process many times over
  • Build-up of detritus around the edges of poorly designed or inappropriate screws—this will increase wetness around the screw area and may contain conductive salts that foster corrosion
  • Trapped moisture around and under the screw head increasing the length of time the steel is wet—speeds up corrosion
  • Water entering the roof cavity underneath poorly formed or damaged screw heads or washers

Anti Corrosive Roofing Screws Climaseal 5 by Buildex

You need to use anti corrosive screws to avoid premature corrosion and expensive and unsightly damage to your valuable roof.

Climaseal roofing screws by Buildex use a unique formulation and coating process specially designed with our severe marine climate in mind.

Although everybody loves the beach and most Australian housing is affected by marine conditions to some extent these are some of the most severe rust causing environments to build in.

You’ve invested heavily to live in this amazing area and you need to know your investment is protected. You need the special protection of Climaseal anti-corrosion screws.

Climaseal fastenings give you real peace of mind with superior rust protection guaranteed.

Climaseal 5 Roofing Screws provides superior protection

Climaseal 5 provides superior protection against the harmful effects corrosion

What are the advantages of Climaseal fastenings?

The Climaseal advantage includes a wide range of screws and fasteners from roofzips to timber and metal self drilling screws and in a range of Colorbond colours.

Climaseal are world leaders in corrosion resistant fasteners because Climaseal:

  • Screw threads feature increased corrosion resistance for greater structural integrity. The area beneath the screw head is often a weak point in inferior screws and damage during the installation process can lead to complete failure of screw. Unfortunately you might not even be aware of this until the roof is damaged beyond repair
  • Screw coatings display increased cracking and chipping resistance
  • Displays enhanced compatibility between screw and roof material, which helps to prevent galvanic reactions causing rust. This includes the washer, which can be a major cause of early failure in inferior screws.
  • Enjoys superior UV resistance protecting the coating against premature degradation under the harsh Australian sun
  • Promises excellent drill performance minimising damage to screw hole edges or incidence of crooked screw entry (which can severely reduce corrosion resistance)
Roofing Screws that have corroded.

What can happen when fastener coating is not compatible with roof sheeting

Buildex are so confident in the Climaseal difference that they guarantee Climaseal 5 products for up to 30 years in marine and 40 years in urban environments.

A longer lasting roof, no ugly rust stains around the screw heads, no expensive premature repairs—now that’s a real return on your investment.

What is Climaseal Coating?

Climaseal is a superior formulation and method of coating that provides a thicker, more even base and top coat.

This creates a more durable corrosion resistant zone and protects your steel roof for longer.

Cross-sections of inferior coatings side by side with Climaseal show a markedly superior performance in Climaseal’s coating integrity against chipping and cracking.

Other galvanized screw coatings quite literally crack under the strain, not Climaseal.

These are cross-sectional views of the Buildex® Climasea® 5 coating

What’s the difference between Climaseal 5 and Climaseal 4?

Climaseal 4 are rated as class 4 roofing screws and Climaseal 5 are rated as class 5 roofing screws.

They are designed for the Australian corrosion zones ISO 9223 known as severe marine and very severe marine.

What does this mean for you?

If your house is between:

  • 1km to 50kms from the ocean or 150m to 1km from a salt water creek or inlet Buildex will guarantee Climaseal 4 for 20 years and Climaseal 5 for 30 years.
  • 400m to 1km from the ocean or within 150m of a salt water creek or inlet Buildex will guarantee Climaseal 4 fasteners for 12 years and Climaseal 5 for 25 years.
  • Within 400m from the ocean you need to use Climaseal 5 and Buildex will guarantee them for 10 years

Replacing your roof can be expensive business and you want it to last. Climaseal gives you the confidence that your roof will last the distance and provide a real return on your investment.

Who is Buildex?

Buildex started in Australia in 1917 and has established a global reputation as one of the leading manufacturers of screws and fasteners on the planet.

Buildex is proud of its Australian roots and its 19,500 square metre manufacturing plant in Melbourne supplies all its Australian customers’ needs as well as exporting to 18 countries throughout Asia, Africa, Europe, and the Pacific.

Buildex was the first company to begin testing anti corrosion coatings in real world outdoor conditions in 1994. This continuous research and development programme has put Buildex to provide truly superior fasteners and screws.

One recent unintended test highlighted Climaseal’s superiority to other fasteners in graphic fashion when a builder ran out of Climaseal screws partway through a job and had to finish with an inferior screw.

The results were dramatic with the Climaseal screws remaining free from corrosion while the other screws quickly deteriorated.

If having a dependable roof over your head is important to you then don’t cut corners.

Get your roof screwed good and proper with Climaseal from Buildex.

The rich earth colours are the foundation and promise of an unforgettable building no matter which profile you choose.

What is Cor-ten A Weather Resistant Steel?

Weather resistant steel (or weathering steel) is a cold-rolled steel alloy that forms its own protective layer.

Whereas the galvanizing process adds a zinc anode to steel during production Cor-ten A steel builds up a protective anti corrosion patina over time and under the influence of the weather.

This protective patina takes on a rich reddish-brown rusted weathered look that will provide a real point of difference and transform your building project into a deeply satisfying iconic masterpiece.

The colourful protective layer forms as a result of various alloys in the steel reacting with the cyclic wet/dry action of the weather and the resulting corrosion products protect the steel from further corrosion for many years.

These anti-corrosion properties are even superior to those of ordinary steel in many applications including industrial settings exposed to exhaust fumes from sulphur content fuels or scaling at high temperatures.

Originally developed by the United States Steel Corporation, the Cor-ten A is made under licence by Ruukki, a Finnish company committed to the care and protection of the environment.

Rusted Steel Cladding

Corten - Rusted Steel Cladding

What are its Special Qualities?

Cor-ten A weather resistant steel retains a special ability to change with time. Within 18-36 months the steel will take on its distinctive rustic appearance.

Although its structural integrity remains intact the patina colour will darken as time goes on. Some variation in colour can be expected but this adds to its eye-catching appeal.

Image is so important these days and whether you want your project to blend in with the environment such as a new house design for an environmentally sensitive site or to stand out from the crowd with an iconoclastic juxtaposition of rustic steel and glass or timber Cor-ten A promises to deliver a visual feast of colour.

Cor-ten is a natural work of art with its deep red, brown, and orange colouring and patterns in constant transformation as the light changes throughout the day.

And when night falls, Cor-ten remains alive as the perfect backdrop for artificial lighting effects.Whatever the weather and time of day Cor-ten A will continue to attract attention and impress.

A clever combination of old rustic appearance, stunning natural colourings, superb strength to weight properties, and corrosion resistance will ensure people talk about your building for many years to come.

Versatility

The possibility of using panel lengths of up to 8 m or more, exceptional strength, and resistance to water ingress make standing seam panels perfect for covering large roof surfaces and in areas subject to weather extremes including torrential rain and even snow.

These panels can be used on any pitch from virtually horizontal (1.5°) to vertical and provide almost limitless opportunities for stunning architectural design.

Structural strength

The standing seam technique ensures the joints display exceptional water tightness and strength. Standing seam panels are generally installed installed on 15 to 18mm ply and are held in place by clips (although the Nail strip profile offers some variation to this rule) . The ply provides a great deal of torsion support and strength.

Sliding clips allow room for movement in building materials and all clips are screwed using countersunk screws into timber framing. The clips are concealed leaving a seamless appearance.

Each sheet has a 25mm to 38mm vertical lip that overlaps with the lip on the neighbouring sheet—the lips are crimped together for a superior waterproof seal. manual crimping technique ensures a tight seal and clean lines while reducing installation time.

Standing seam panels are designed for longevity. Colorbond Ultra, Aluminium, Zinc and Copper increase the natural anti-corrosion properties of standing seam panels making them a perfect solution for coastal construction and other projects subject to salt laden winds.

Standing Seam
