Technical Documents
Key technical documents for all products including performance and selection information can be easily downloaded from the links on the right.
IMPORTANT: All relevant codes applicable to the location of installation must be observed to achieve a compliant outcome. Regulators also may vary in their approach; a specific guide to the requirements in VICTORIA can be downloaded on the right.
Dam Buster does not provide any project advice and correct usage of our products is entirely the responsibility of the relevant installer/certifier.

Performance Solution Templates
These easy to use Performance Solution templates have been prepared as suggestions to assist with the Performance Solution Process for all original Dam Buster products which have independently certified performance capabilities.
For obvious reasons, none of this information nor any of the other information on this website, applies in any way to any non-genuine Dam Buster product or products. Making fake copies, along with copying these documents in whole or in part is a breach of copyright and our patents, so please just buy the real thing from our Authorised Licensees.
IMPORTANT:
Dam Buster takes no responsibility for any Performance Solution prepared using these templates; they are a suggested format and/or method only and must be used solely by suitably experienced and qualified persons. Users must validate all documents, make all necessary calculations independently, and otherwise take all steps necessary, including the engagement of appropriate additional experts if deemed appropriate, to ensure a fully compliant outcome arises from the use and installation of all our innovative products.

Rainhead Overflow Performance Test Certificates
Independent rainhead testing was carried out by the AHSCA Research Foundation (AHSCARF) at the purpose built National Research Drainage Facility at the University of the Sunshine Coast, Queensland. All Dam Buster rainheads are AHSCARF certified products and independent Test Certificates for each size can be downloaded on the right.
More information about the AHSCARF can be found at https://www.ahscaresearch.com.au
NB: These certificates show images of rainheads with either round or rectangular secondary front overflows, however all testing conducted by the AHSCARF and referenced in these certificates was carried out with these secondary front overflows fully blocked. The AHSCARF testing also confirmed these additional overflows were not necessary and hence have since been deleted from all later Dam Buster production.
The test certificates therefore apply to all Dam Buster rainhead products regardless of series, date of manufacture and/or whether or not they have a secondary front overflow device fitted.
