RAINWATER MANAGEMENT
a flow rate of 5.10 litres per second (outlet at centre) when compared to 2.43 litres per second for a traditional half round system. For larger scale commercial and industrial projects, the 170mm Deepstyle gutter offers a massive 10.24 litres per second. Brett Martin can assist merchants and their customers with a take-off service to calculate rainwater requirements and if necessary, site visits can be arranged.
Quick to fit
The significant additional weight of cast iron drainage systems makes them difficult to install. Builders must also be extra vigilant regarding health and safety and will require more time to lift and fix the system – leading to increased costs and potential delays in the installation process.
This is where the plastic ranges come into their own as they are so much lighter than cast iron. Installation at height is less hazardous, being effortless to lift, easy to manoeuvre, simple to cut and quick to fit. The systems also benefit from external fixing lugs, enabling easy power tool access, which further speeds up installation. All gutter fitting joints have integral moulded seals and flexible retaining clips, allowing the gutter lengths to simply click into place for maximum sealability. No extra-cost fixing kits or nuts and bolts are required to make gutter joints, as with most traditional systems. These plastic solutions are therefore less likely to under-perform due to poor installation.
To ensure each rainwater system can be designed to meet every client’s demands, there are an expansive choice of colours and gutter profiles available for domestic builds and refurbishments to suit most requirements. Plastic rainwater systems are also compatible with existing cast iron systems and have
been carefully designed to replicate original features, dimensions and detailing. The Cascade cast iron effect rainwater system from Brett Martin is the original cast iron effect system and for the merchant, upselling from a standard rainwater system to Cascade offers the potential to increase margin every time. In addition to the popular Classic Black colour, Cascade is also available in a choice of seven heritage colours including Anthracite Grey, Oxford Blue, Chartwell Green, Olive Green, Graphite Grey, Sandstone and Porcelain White - all of which cater to the subtle nuances of local vernacular architecture. The complete colour range delivers the traditional appearance of cast iron with the convenience of modern plastic materials. Cascade is also UV-stabilised for a maintenance-free system that will stay looking great and working well for years and comes with a 10-year guarantee.
Standard assessment
Regardless of the rainwater system selected, it is critical to check it has been tested to the relevant industry standards as this will ensure it is capable of withstanding the most rigorous performance assessments. A rainwater system’s long term performance capabilities are tested through assessments of impact and tensile strength, load bearing capacity, watertightness, deformation resistance and the impact of accelerated ageing and any reputable manufacturer will ensure rainwater systems perform as such. For example, Brett Martin’s uPVC rainwater systems undergo testing in accordance with BS EN 607:2004 and BS EN 1462:2004.
With inclement weather becoming more frequent, a proven solution to manage the risk of flooding and excessive rainwater run-off, is

Brett Martin’s StormCrate55, an engineered Sustainable Drainage System (SuDS) used where alternative drainage solutions cannot be achieved. The modular crates are stacked or laid to form an underground tank that attenuates water for re-use or discharge after a storm passes, or alternatively through infiltration back into the ground naturally. For housebuilders, mitigating the risk of flooding and making the best use of land available are key, and StormCrate55 is typically installed underneath a car park or ‘green area’ in developments. The crates are made from externally sourced recycled polymers and all- round makes StormCrate55 an environmental product choice.
Sustainable supply
As a company, Brett Martin is very conscious of its environmental responsibilities and is committed to reducing its carbon footprint with investment in renewable resources. All the plumbing and drainage ranges are manufactured at the Mallusk site where 50% of energy comes from on-site and external renewable sources and at the Staveley site which runs on renewable energy tariffs
