Structural sealing

We are your competent point of contact for all questions relating to the new and further development, use and testing of sealing products and solutions. Alongside practical and large-scale product tests, we also perform expert assessments of moisture damage and defective waterproofing, locate points at which moisture is entering, develop repair solutions, provide advice in the selection of sealing solutions and check that these have been properly implemented.
