Environmentally friendly liquid seal


In many situations concrete needs to be waterproofed. It prevents water from penetrating into the construction or to protect the steel reinforcement that is inside the concrete.

Liquid Rubber is the right product to realize a durable protection of concrete. Whether it is to seal entire surfaces like basements or concrete decks, or concrete details and connections, Liquid Rubber has the right solution. Liquid Rubber provides a seamless and highly flexible coating with a durable flexibility of 900%. Because Liquid Rubber is fully seamless, the product has no weak spots or overlaps that could cause leaks.

Liquid Rubber is commonly used as a sealant on basements, foundations, ground level details, parking decks, silos, storage wells, manure pits, construction joints, retaining walls, sand-lime walls, Ytong blocks, prefab elements and many more. This applies to new constructions but also to renovation. Liquid Rubber can easily fix the cracks in concrete. And because of the durable flexibility, it can cover the cracks for a long period of time.

Air barrier construction

Liquid air barrier sealing is a well-known concept in Europe these days. Air barrier is to seal all the unwanted seams and joints in a construction. This way, all the uncontrolled airflows will be prevented. This results in controlled airflows and the energy loss will be minimized. Air sealing is one of the pillars of energy efficient construction.

Liquid Rubber HBS200 is commonly used as a liquid air barrier in all sorts the European construction. Liquid Rubber is an easy but very effective product. The product adheres to light wet surfaces, adheres to almost every surface and can be applied very easily with a brush, roller or airless spray system. Because of the high flexibility (900%) and the lowest possible air tightness measurement (0.0004L/(s.m2)), Liquid Rubber ensures a high quality and durable sealant.

The product can perfectly be used to seal the connection from window frames, connection foundation to wall, around pipes and outlets, joints of prefab elements, connection wall to roof and many more.

Waterproofing roofs can be a difficult job. Liquid Rubber HBS200 and the Liquid Rubber SprayGrade are ideal products for many roof sealants. These products can be applied on many existing roofing products like bitumen, EPDM (pre-treatment), APP, PVC and many more. This way, old existing roofs can easily be renovated without having to remove the old roofing.

The HBS200 can easily be applied with a brush or roller to seal all kind of roof-details like: pipes, outlets, drains, up-stands, roof windows and so on.

Liquid Rubber SprayGrade can also be applied as a waterproofing layer on insulation panels like PIR, EPS, XPS. Liquid Rubber can be applied directly on top to ensure a seamless and durable waterproofing layer.

Liquid Rubber is also the perfect product to waterproof gutters. It adheres perfectly to zinc and lead. Because of the adhesion and high flexibility the product can be applied on new gutters but also on old gutters.

Liquid Rubber is frequently used as a sealing- or protective membrane on all kind of Road- and water constructions. The liquid and seamless membrane is being used on concrete bridge decks, composite bridge decks, parking decks, parking garages, ramps, tunnel constructions and many more.

Liquid Rubber is also suitable as a waterproofed protective layer underneath the asphalt. All the water that will penetrate through the asphalt will not get in contact with underlying construction. This way no damage or leaks will occur. This is perfect for tunnels, bridges and parking garages or parking decks.

All the Liquid Rubber systems are cold applied and fully environmentally friendly. A very interesting feature that comes with this durable sealing product.

Corrosion is the process where metals, which are exposed to oxygen and water, will start rusting. Corrosion is an oxidation layer that grows on the surface of the metal. Corrosion is a major problem and occurs in many different situations. Corrosion prevention or the treatment of corrosion is essential in many circumstances.

Liquid Rubber can be used as corrosion prevention and corrosion renovation. Liquid Rubber is fully waterproof, resistant against chemicals and salt. The product adheres perfectly on almost every metal surface. It seals the surface and will not allow any water or air to get in contact with the metal. If the Liquid Rubber gets mechanically damaged, the corrosion will never expand underneath the Liquid Rubber. The mechanical damage is easy to repair with the Liquid Rubber HBS200 because it will fully vulcanize with the existing product.

Liquid Rubber is also perfectly suitable to cover existing corrosion. The product adheres to corrosion and will seal the corrosion from water and air. This will naturalize the corrosion process. Liquid Rubber is frequently used to protect metals on steel walls, steel construction, steel pillars, halls, panels, silos and many more.
