Key Considerations for Your Outdoor Drainage Project

Poor drainage design and surface grading can exacerbate surface runoff (an environmental hazard) and cause substantial damage to landscaped areas.

Moreover, poor drainage flow, resultant from substandard drainage design and placement, remains the chief cause of ponding, which can degrade impervious surfaces and cause serious structural damage to any property. Here are some of the key considerations for your outdoor drainage project to help architects, specifiers, builders and skilled DIY practitioners select and implement the best drainage solutions.

1. Drainage Layout & Availability

One of the chief considerations for outdoor drainage sites is their access to existing plumbing and drainage systems.

The advantage of new building sites is that most allow for drainage systems to be established in order to meet the ‘lay of the land’, ensuring maximised water flow and adherence to best practice water-sensitive design principles (WSUD). However, older properties may offer fewer possibilities for alteration, and may be better suited to more traditional drainage arrangements.

Building surfaces (such as earth, stone or concrete) will also impact one’s ability to move or increase the number of available drains.

2. Use of Outdoor Area

If your drainage area is heavily trafficked or used for vehicular access/parking, it is critical to ensure your drainage solution can bear the weight of these excessive loads.

Many drainage solutions offer superior load ratings to ensure they can withstand these load forces and avoid buckling even under constant load pressures.

3. Environmental Concerns

Australia’s unique environmental challenges will greatly impact on the type of drainage materials and grating required for your outdoor area.

Key external variables such as exposure to airborne salinity (i.e. proximity to seashore), tree debris (e.g. leaves and seeds), exposure to urban pollutants (e.g. PAHs and corrosive chemicals) and even weather (dry arid versus wet tropical) conditions will all have a significant impact on the type of drainage you require and the materials best suited to withstand these unique environmental conditions.

Boasting an unrivaled depth of experience with linear drainage solutions, Stormtech welcomes questions about product selection and compliance, and can advise prospective clients on the most suitable drainage product for your building project.

Our skilled specialists work closely with specifiers, architects and builders to offer tailored drainage solutions, including bespoke drawings and plans for customised drainage designs. We work proactively with plumbing advisory services to ensure drainage is not only fit for purpose, but meets stringent Building Code of Australia (BCA) compliance measures.

How Proper Planning can stop your project going down the drain

Drains are a vital element of any residential or commercial project. When properly installed, they are effectively out of sight and out of mind, and ensure that important everyday activities including bathing, cooking, and washing can be done safely and efficiently. Unfortunately, drain planning is an often-overlooked element of the construction process. In this whitepaper, How Proper Planning Can Stop Your Project Going Down the Drain, we take a closer look at the importance of planning drain installations. The whitepaper outlines the main factors that must be taken into account when planning a drain: location, drainage style, timing of construction, and regulatory compliance and details the complex regulatory framework surrounding drainage products in Australia.

Drainage Selection Guide: 15 Common Applications Areas

The bathroom, and specifically the shower, is often thought of as the most important space to ensure good drainage. However, there are many other spaces that require consideration in relation to adequate drainage. This whitepaper addresses 15 different potential drainage application areas into clear sections, and highlights the importance of ensuring proper drainage in each area. In each section, potential safety hazards, installation shortfalls, and area-specific challenges are identified. The paper goes on to explain how in most cases, Stormtech’s linear drainage systems offer the best solution to these problems.

Compliance of Regulations and Why It Matters

The issue of non-conforming and non-compliant products affects every stakeholder in the building industry. By ignoring regulations, building professionals endanger, not only their own reputation, but also the status of the entire industry. The plumbing industry has a number of regulations that are important to adhere to. Aspects like minimum size requirements, load restrictions and accessibility are vital for the success of plumbing and drainage systems. In this white paper, we examine why it is important that everyone plays by the rules.

The Pitfalls of Investing in Low Grade Drainage

The importance of choosing compliant and conforming products in construction is regularly discussed in the media and within the industry. The most dramatic examples of the failure of substandard products – such as the Melbourne Docklands fire and the Infinity cable recall – are widely broadcast, yet the range of implications involved in choosing cheaper products remain largely underreported. For building professionals, it is important that the hallmarks of sub-standard drainage systems are easily identified so informed decisions can be made. Products demonstrating reduced flexibility can signal low quality, as they are only relevant for general applications. A cheap solution also suggests a lack of testing, or a short research and development period, which could lead to problems later down the line.    

Specifying Balcony Drainage Systems

Balcony design, and in particular drainage systems are a critical design consideration for multi-residential developments. Balconies are an external element of the building that must be properly integrated to work with the internal elements of the building. Balconies require appropriate drainage and isolation from the internal elements of the building.

The Pacific Bondi Case study

In December 2015 Bondi’s newest development, Pacific Bondi, was completed, taking the areas luxury living to a whole new level. To meet the requirements of the hostile beachfront environment, as well as the expected high-traffic hotel and public areas, Stormtech supplied 316 marine grade stainless steel linear drainage for the bathrooms, balconies and panoramic atrium areas.
