Reliable waterproofing for bridge decks

Bridges are crucial connections in our infrastructure and are constantly exposed to heavy loads, weather conditions and thermal stresses. Sustainable waterproof protection of bridge decks is therefore essential. Liquid Rubber BelowGrade offers a proven effective solution as a hydrophobic coating under asphalt pavements.

Choose the durable protection of Liquid Rubber BelowGrade and extend the life of your bridge structure - with assurance under every layer.

Long-lasting protection against weather and traffic

The two-component system of Liquid Rubber BelowGrade has been specially developed for applications that do not involve UV exposure and offers excellent adhesion and flexibility. Liquid Rubber BelowGrade has been extensively tested for its resistance to high temperatures and is fully resistant to hot asphalt application. Laboratory tests show that the seal remains fully intact after asphalt application and does not allow water to penetrate, even under long-term loading.

In addition, Liquid Rubber BelowGrade is resistant to temperature fluctuations and chemical stresses - making it ideally suited to bridge projects where reliability and longevity are key.
