With its two strong brands Rajasil Bausanierung and HECK MultiTherm, Colfirmit Rajasil is one of the leading producers of renovation and refurbishment products and heat insulation systems in Germany. Based in Marktredwitz, Colfirmit Rajasil has been active on the market for 100 years now. With a current work-force of about 200 employees, Colfirmit Rajasil is part of the BASF group, the world’s largest chemical company.
At Colfirmit Rajasil’s fully-automated production facilities we produce mineral-based dry factory-mixed mortars and specialized construction materials for the durable refurbishment of precious historical building fabrics as well as for new construction projects.
Our portfolio comprises products for the renovation of masonry, truss, and natural stone constructions and facades, as well as render and coating systems and exterior insulation finishing systems.

Growing technological, economical, and ecological demands require an ongoing adaptation process for products. Our company, which is certified according to DIN EN ISO 9001:2000 as well as DIN EN ISO 14001:1996 (quality- & eco-management), particularly emphasizes the use of environmentally sound materials during the production process. In our state-of-the-art laboratories, scientists and engineers are working tirelessly to make existing product systems even better and to develop new ones. In this, we have additional support from BASF’s own Construction Chemicals Competence Center in Trostberg as well as from various BASF research facilities all over the world. In our laboratories we also analyze historic building materials for the development and production of specialized formulations for the preservation of monuments and historic buildings.
On-time delivery is ensured by the utilization of company-owned trucks and our sophisticated logistics infrastructure that includes several off-premises warehouses. In most cases, we are able to deliver standard products to Germany-based customers the day after receipt of the order.

We ensure the best-possible customer service and support through regular in-house trainings for our employees; application and demonstration engineers complement our on-site service teams.
Our additional services include a broad selection of trainings and seminars for architects, applicators, and specialist retailers.
