The waterproofing of bridge-deck is necessary to enhance the durability and longevity of road bridges. BMI high performance waterproofing solutions, designed to withstand even the harshest weather conditions, help to prevent penetration of corrosive agents such as water, polluted air, carbon dioxide and de-icing salts that can cause the structural damage to steel reinforcements within the concrete. 
Our high quality bituminous membranes with outstanding mechanical strength are suitable for use on both new and existing surfaces and can either be manually or mechanically torched in place.
