Technology to Respyre

Bio-receptive concrete

Respyre has developed –patent pending– an innovative bioreceptive concrete solution. After hardening, the bio-receptive concrete’s surface accommodates the growth of moss.

Several unique characteristics of our concrete make it bio-receptive which include its porosity and water retainment, micropore texture, acidity and nutrients that are included in the mixture. These characteristics create the perfect setting for moss to thrive on.

Moss is incredibly well suited for green facades as moss has rhizoids instead of roots. Roots are very invasive and demand a lot from the substance they grow from. Rhizoids are nondestructive, they mainly function as an adhesive, leaving the façade in perfect condition. Our bio-receptive concrete creates a with specifically with the anchors rhizoids require.

Quick, Easy and cost Effective

The solution can either be plaster, a prefabricated concrete element or concrete poured on location. Meaning that our product can easily be applied on existing structures but also efficiently incorporated into new projects. Making our product a quick, easy and cost-effective way of incorporating nature in the urban environment.

Once placed in a suitable environment the bio-receptive concrete facilitates the spontaneous growth of moss. With the added nutrients moss is incited to grow quickly. Alternatively the moss can also be grafted, leading to even quicker results. Either way, moss will have covered the surface of our solution within a month and immediately start to provide its benefits.

Unlike other green façades our moss façades require no complicated anchoring system. Our solution provides all anchoring the moss needs as well as an environment where it can thrive autonomously. A moss façade based on our solution requires no tending to, making it an even more cost-effective solution.

Autonomous respiratory system

The strength of our product lies in nature’s design, the characteristics of moss. It is moss that provides the benefits we seek, our job is to bring the tiny plant in large amounts in to city. Our bio-receptive concrete provides the accommodation but our work doesn’t stop there. We ensure that these natural systems do not require extra tending and thrive autonomously.

Together with our solution we provide our clients with our knowledge and expertise in moss. We help select the right type of moss for the right environment, advise on suitable locations for our solution and assist in the design of facades when necessary. We do this to ensure everything the system needs is provided by natural precipitation and provides its natural benefits without extra intervention.

The variety in moss species is extensive. This provides us with the opportunity to mix and match the most beneficial types specifically for every project. Choosing the right types ensures the health of the system and its positive contributions to the environment.

Additionally, being able to choose the moss that grows on our solutions, combined with the ability to accurately arrange its growth enables us to provide extremely aesthetically pleasing results.  

A sustainable solution

Aside from the positive effect on the air quality our solution is sustainable all-round. Our bio-receptive concrete is produced by using recycled concrete aggregates and other residual streams. Minimizing waste and pollution generated during our production process.

During its life the green facades facilitated by our bio-receptive concrete can also have positive effects on the structure it is applied on. Through evapotranspiration of retained water the moss can cool the structure down. Additionally the green façade protects the structure from the forces of weather, which can contribute to lengthening the life of the structure.

Currently we are expanding our team, needing pretty much anything that makes a business thrive!
