Lime and Hempcrete Specialists
At Platinum Contractors Group LTD we specialise in sustainable renovation solutions for a greener future.
We aim to breathe new life into old buildings like town houses and barns as well as creating eco-friendly new builds. Our commitment to sustainability lies in the products we use, (Lime mortar & Hempcrete) which ensure your build delivers thermal and acoustic properties, in addition to capturing and offsetting CO2 emissions, all of which is backed by full certification on energy savings
Hempcrete is a revoloutionary bio-composite material, consisting of three main components: hemp, shiv, a lime-based binder, and water. The hemp, shiv, which is the inner core of the hemp stalk, is known for its ability to trap air and regulate moisture. Combined with a lime-based binder, the mixture creates a lightweight, durable material with exceptional insulation properties. What makes hempcrete unique is its thermal and acoustic performance. The material absorbs and releases heat slowly, maintaining a stable indoor temperature and reducing energy costs.
Additionally, its porous structure helps absorb sound, making it ideal for noise reduction in buildings. Another key advantage is its breathability. Hempcrete allows moisture to pass through its structure, preventing dampness and mould. This makes it an excellent choice of material for a healthy, sustainable build.
One of the most remarkable aspects of Hempcrete is its Carbon negative footprint.
Hemp plants absorb CO2 from the atmosphere as they grow, and this carbon remains stored in hempcrete even after construction. this makes it a powerful tool in reducing greenhouse gas emissions. Additionally, hemp is a fast growing renewable crop that requires minimal water and no synthetic fertilisers or pesticides. This is in contrast to many traditional construction materials which often rely on resource-intensive production methods. Hempcrete also supports the principles of a circular economy where materials are reused/recycled rather discarded.
Hempcrete can be applied using several techniques, each suited to your different build requirements.
The first technique is, On-site casting. This method involves mixing hempcrete and pouring it into temporary formwork around a timber frame. This approach offers flexibility in design and results in seamless, well-insulated walls.
Another option is the use of, Pre-cast blocks and panels, which speeds up construction and ensures uniform quality. These elements are manufactured in controlled conditions and then assembled on-site.
For larger projects, spraying hempcrete is a very efficient method. This technique involves the use of specialist equipment to spray the hemp-lime mixture onto walls, significantly cutting down on site construction time whilst still maintaining the same standard of insulation and breathability.
