Using waterproofing technologies for bridge decks and concrete support surfaces reliably protects bridge structures from adverse moisture effects.
Bridge Deck Waterproofing (Silla tekki Hüdroisolatsioon)
Bridge deck waterproofing protects against precipitation, meltwater, and chemical agents used to combat ice.
Work Procedure:
- Inspection and assessment: Evaluating the condition of the bridge deck and identifying areas needing waterproofing.
- Surface cleaning: Removing dust, dirt, and other contaminants from the deck surface.
- Surface preparation: Levelling, fixing minor defects, and applying a primer.
- Laying the waterproofing material: Choosing the appropriate waterproofing material (bituminous membranes, liquid polymer coatings, roll materials, etc.) based on bridge operation conditions and project requirements.
Concrete Surface Waterproofing
Applying waterproofing coatings to concrete bridge surfaces aims to protect the bridge’s support structures from moisture and aggressive environments. The materials used create a waterproof barrier that prevents water penetration into the concrete and reinforcement, reducing the risk of corrosion and damage.
Work Procedure:
- Surface cleaning: Removing dirt, oils, dust, and other contaminants from the surface.
- Damage repair: Filling cracks and potholes, levelling the surface to ensure even application of the waterproofing material.
- Drying: The surface must be dry before applying the waterproofing coating.
- Primer application: Applying primer enhances the adhesion of the waterproofing material to the concrete surface. It is applied with a brush, roller, or sprayer and allowed to dry.
Waterproofing application: Waterproofing coatings based on bitumen, polymers, or liquid rubber are applied in several layers according to technical requirements.
