MAINTENANCE
Green roof maintenance is a service available for all green roofs even if the project was not carried out by Ohasis Tech. Our maintenance team is professional and can take care of your commercial, institutional, industrial or residential green roof.
Our maintenance team has been trained to extend the life of green roofs. Indeed, the main cause of green roof removal is the lack of maintenance and out of control weeding.
The complete maintenance protocol is available here if needed.
Contact us to learn more and to estimate the annual maintenance costs of your green roof.

Tailor-made
All Ohasis systems, from prevegetalised to built-in-place, can be composed of a unique plant mix chosen by the customer.
Ohasis modules can mix up to eight different types of sedum to have colors that change throughout the year.
The 6'' modules and built-in-place systems can accommodate a wide variety of perennials and grasses that allow for stunning rooftop terraces.
We work with local horticulturists to give you access to the largest choice of plants available for a green roof.

CONSULTATION
Our specification consultation service is mainly aimed at professionals like architects.
Specification is an important part of the job and it is sometimes difficult to achieve the desired result if you are not familiar with the available technologies.
Working with specification experts means ensuring your client receives a result that meets their expectations.
We started offering our services in consultation because we see a lot of specification errors that can greatly harm or even completely ruin the outcome of the project.
A one-hour meeting is often sufficient to adequately determine the needs of the project.
