“Hemp will be the future of all mankind, or there won’t be a future.” Jack Herer

Our commitment at Haven Earth is to build a bright, eco-friendly future through specialized collaboration and heart focused ethics. By developing prototype holistic living models, structures, homesteads and communities that are self-regenerative, and fully supporting and integrative into natural settings, we are taking our first steps towards the creation of our future reality. By including food, energy and water independence, and creative ways to up-cycle waste element, we see a vision of the future, worth living for. We believe in quality in creating legacy projects with the use of Hemp. To do this, we nurture relationships with producers that support building homes and structures with hemp. We are working toward bringing together all the elements of the Hemp related model, through actualizing its versatility and uses in real time with real life examples. We are creating the ‘Way’ and bringing hemp to life in these dormant agricultural region by utilizing this amazing plant to build relationships within the region and support the development of Hemp Agri business and eco- communities from ‘seed to home’.

Hemp

Hemp is a phenomenal plant, and has finally come of age, offering a massive range of solutions that are much needed at this time. Not only that, but the Hemp plant brings people together, and into balance with the natural world, through conscious agrarian models of business, building, clothing, food, and much more. Hemp gives us the opportunity to regenerate our forgotten relationships and abundance with and in nature, as we learn to grow our lives again.

Hemp Processing

We are working with the growers of the Hemp plant in many areas in the United States, on a range of projects, developing strong relationships with those that are at the forefront of the chain, the ones who are putting the seeds in the ground, and nurturing the plant to its maturity through its short growing cycle of around 3-4 months.  From there, a mechanical process is presently employed to separate the parts of the plant that are of use as building materials, and textiles. On the processing side of things, we are working alongside the innovative companies who have been in the business of pioneering the machinery for the processing of hemp for fiber and building materials, with the aim of providing the tools to grow this industry. We see these collaborative relationships as an essential part in working with Hemp as a building material, as it’s the entire chain of people working from growing to installation, that can make this happen, and the construction industry is primed to pivot to more ecological natural ways at this time.

Hemp Hurd

After the decortication process is complete, and the different elements of the plant are separated, we get to the parts we can use in building, which is called ‘Hemp Hurd’. Hemp hurd is the soft woody core from the center of the stalk of the Hemp Plant. The fibrous coating around the stalk, which is used for fiber (textile), is removed from the woody core through a process called Decortication, and then it is chopped into small pieces (between ½ – 1”) to be used in the mix. The quality of the hurd is essential for a positive outcome, and is why we only source our hurd from quality sources, and as local as possible. This guarantees our projects are robust, long lasting and very well executed.

Hemp-Crete

The process for working with hemp that we utilize for our projects is often called Hemp-Crete (or Hemp-Lime), and is a mix of Hydrated Lime, Hemp Hurd, Clean Water, and Natural Mineral Binders. Together this combination creates a non-structural building infill material that is natural, mold and rot resistant, fire resistant, super insulating, and has amazing acoustic properties. Not only that, but hemp-create walls and infill are a breathing system, that utilize the open cellular structure of the Hemp Hurd (Shiv) to retain moisture and other impurities, and release them again when the conditions are appropriate, essentially our structures become living/breathing systems requiring little if any ventilation in the space, as the air is not trapped inside the interior spaces, but rather a constant flow of fresh air is felt and experienced inside the building.

Hemp Binder

When we mix Hemp Hurd and Hydrated Lime together, we enable the process of calcification, yet the mixture takes too long to dry. To speed the process up to a point where we can work with the materials, we use mineral binders to create a hydraulic action on the lime, which speeds the process up, and the lime essentially turns back to limestone.

Hemp eco Systems (link www.hempecosystems.org) who’s mineral binder products we have been using thus far, reflect more than 25 years of experience with hemp building in Europe. Based in Switzerland their formula for the mineral binders are offering great solutions, tried and tested methods and materials to create our structures to the highest level and integrity, from 100% natural materials.

Basalt

Basalt is a natural material that is found in volcanic rocks originated from frozen lava. Basalt fibers are 100% natural and inert, and Basalt products have no toxic reaction with air or water, are non-combustible and explosion proof. It is an outstanding product for concrete reinforcement, and other products for building in place of steel, such as Besalt mesh for plastering. It weighs 4 times less than steel and its tensile strength is 3 times higher. Basalt rebars are manufactured from basalt fibers by pultrusion technology. The surface is profiled and sanded.

Basalt applications are well known from roman age where this material was used in its natural form as a paving and building stone. Basalt is known for its excellent mechanical properties, resistance to moisture absorption, resistance to corrosive liquids and environments, durability in service and great versatility. Basalt rebar is resistant to a corrosive environment, and makes it an amazing material to use in conjunction with Hemp and Lime.

Super Adobe

Super Adobe, is a technique of utilizing long tubular polypropylene bags, filled with a  mixture of earth, clay, lime, and/or cement. The bags are durable yet biodegradable and used in combination with Barbed wire, which creates tensile strength and anchors the layers together.. This technique is very versatile, and some of its most appealing properties are; its ability to resist seismic activity due to the nature of the layered system, and its resistance to fire. The limited amount of materials required, make it a great building technique for projects that may not have easy access to material transportation, remote locations, and low budget projects. At Haven Earth we see Super Adobe as a very useful method we can incorporate when the project requires it, and have successfully pioneered the technique with great success in several countries, and locations.
