Bamboo Planting, Bamboo Forest Management and Removal
RHSA offers support to anyone interested in growing, harvesting, and managing bamboo safely and sustainably. We are also able to map existing bamboo forests using GPS technology and assist clients in species identification. Finally, we are able to use the data to model the best solution for our client’s needs.
As there are many uses across the bamboo species, we offer advice to landscapers and growers of bamboo.
Bamboo Consultants and Specialist Contractors
We offer design and build services for the most popular uses of bamboo, including pergolas, screens, fences and cladding. It is also possible to execute a variety of interior designs or non-habitable structures using bamboo, as the material is strong and comes in many shapes and sizes. How do you think bamboo can help with your project?
Skills Development Workshops
RHSA offers a skills development workshop consisting of a theoretical and practical component. Over the course of several days, participants will learn about the bamboo plant as well as get hands-on with bamboo application in craft and construction.
Bamboo is a versatile material and has many building applications. However it is not a silver bullet, and care needs to be taken to protect bamboo from water, particularly at the base of a structure. As such, we recommend using bamboo for frame structures, roofing, screening and cladding. Check out our construction guide for ideas and techniques!
Only if you plant an invasive running species! If you want bamboo, make sure you are planting a clumping species, which has a rhizomic (root) structure which does not spread indiscriminately. Please call us if you need advice on species and propagation. Or, check out our growing guide for extra tips!
Sadly, with immense difficulty. This is because underground rhizomes (roots) can travel up to 30m from the previous growth cluster, making it very difficult to see the extent of the spread, and also to remove the plant. Check out our growing guide for extra tips!
Absolutely yes. Earth building is one of the oldest building traditions of human-kind. Earth buildings perform exceptionally well thermally, and can last 100s of years if built correctly. There are numerous techniques for building with earth, the most popular being: Rammed earth, Compressed Stabilized Earth Blocks (CSEB), earth-bag building and wattle and daub. Each technique has its pros and cons. Interestingly, it is possible to build sound, long lasting structures like arches, vaults and domes, from CSEB. Similarly, sand-bag construction is suited for domed structures.
Earth building is a resource and labour intensive material to work with, the costs of labour generally being worth more than the raw material itself. The process of building with earth demands an in-depth analysis of the soil type to be used, which will help determine which earth-building technique is best suited. Also, quarrying the material needs to be considered within the greater context, and integrated into water management systems, or landscaping. We do not advocate the indiscriminate mining of soil as this results in unnecessary environmental degradation.
Our latest CSEB building is Albini church in Ntshongweni, KwaZulu Natal. RHSA were the CSEB consultants on this heritage project, which saw the tripling the capacity of an old stone church.
We are based in Durban KwaZulu Natal, and we work mainly in the greater eThekwini and Msundizi areas, as well as the North and South coasts of KZN.
