Horizontal Applications

Vehicular Wearing Surfaces

The container docks in Singapore are on suspended structural slabs. The surface of these slabs take a lot of beating and wear and tear from heavy, rubber-tired mobile cranes that exert high traction forces on the concrete decks. Normally, the patching of these decks by conventional means require saw-cutting and excavation of the top surface of the concrete to place a patch thick enough to withstand heavy traffic forces. The patching material is normally an epoxy or polymer concrete. Not only is it expensive to prepare and install, but the down time element is a major factor. Furthermore, these conventional materials last only six to twelve months before repairs become necessary again. Space on the container docks is at a premium and containers are stacked seven high in order to preserve space. To shut down any one area for repair would involve severe interruption of scheduling, movement of the containers and loss in revenue.

With DURUS® High Tech Cement, there is no need for saw-cutting or demolition. The areas to be patched are washed clean and DURUS® is applied directly on the rough concrete. The thickness of the application can vary from 1/8” (3 mm) or more and feather edge down to zero. This product has been laid on the Singapore docks for over five years and is performing extremely well. It is now the standard material for patching and repairing dock surfaces at the Singapore port.

Skid Resistant Surfaces

This product is also used extensively in coating smooth concrete surfaces to develop frictional resistance in preventing vehicular skidding. This hazard is particularly present in aircraft baggage transfer areas where trucks and carts are exposed to rain. The wet tires tend to skid on the smooth slabs and collisions due to loss of control of the vehicles occasionally occur.

To prevent skidding, DURUS® High Tech Cement has been used successfully to coat baggage transfer areas of Sinagpore’s Changi International Airport and Honolulu International Airport.

Concrete pavements at bus stops in Singapore have also used DURUS® High Tech Cement coatings to resist wear and prevent skidding.

Levelling Surfaces

DURUS® High Tech Cement is also used to fill in low areas where water ponds, as was the case at Honolulu International Airport’s Interisland Terminal roadway. DURUS® High Tech Cement is an excellent fill material for ponding problems as the edges can be feathered from any thickness down to zero.

At Singapore’s Changi Airport, ponding of rain water on the aircraft parking aprons often hinder operations. DURUS® High Tech Cement is used to fill low areas to effectuate drainage and eliminate standing water.

Surface Crack Repairs

As a filler for shrinkage cracks, DURUS® High Tech Cement fully bonds to all contact surfaces and free edges and provides full restraint against cracking in the free edges. In addition to filling the existing cracks, the entire surface immediately above and slightly beyond the crack-filled areas is coated with a thin 1/8” (3 mm) layer of DURUS® High Tech Cement to provide a shield along the patched area and develop total monolithic action between the new patch and the older concrete, protecting against further cracking or spalling.

At the San Francisco International Airport, DURUS® is used as a standard method of patching and refinishing aircraft parking aprons. The patching is needed because loose slivers of concrete along the cracks tend to get sucked up by jet engines causing damage to jet engine fan blades. To prevent these slivers from forming and being sucked up by the jets, the cracks are repaired with DURUS® High Tech Cement to form a monolithic surface.

Asphalt Concrete Coating & Restoration

When DURUS® Asphalt Armor is applied on asphalt surfaces to protect it from potential penetration of water. Water seeping through the asphalt concrete layer can soften the subgrade, which would result in foundation failure and potholes.

DURUS® Asphalt Cement will coat and bond to deteriorating asphalt greatly prolonging the life of the pavement. The cement prevents further unraveling of the asphalt pavement producing a new and more durable wearing surface. DURUS® Asphalt Cement is finished with DURUS® Asphalt Armor for additional protection.

This DURUS® Asphalt Cement and DURUS® Asphalt Armor treatment was employed successfully on the helicopter repair pads and taxiways at Kaneohe Marine Corps Base Hawaii. DURUS® Asphalt Crack Filler is also utilized to fill asphalt runway cracks at this military base.

DURUS® Asphalt Cement and DURUS® Asphalt Armor will extend the life of asphalt pavements with minimum down time required for application.

Vertical Applications

DURUS® Plaster Basecoat

In London, the exterior wall and facade of the Gloucester Hotel was originally surfaced with a blue mosaic and chestnut brown colored ceramic tiles. Over time these tiles aged in the weather, resulting in efflorescence and unsightly stains and some tiles peeling off. The building was nearly 30 years old and the new owner desired a change in its color and texture. The proposed conventional treatment of removing the ceramic tiles, applying the standard cement plaster coat with wire mesh and painting the surface would have involved considerable nuisance as the ceramic tile would have to be jack hammered out resulting in noise, dust and the need to haul away the debris. It would also cause a partial shut-down of the hotel operation resulting in significant down-time and loss of revenue.

With the DURUS® method, the ceramic tile was simply washed clean and coated with a layer of 1/8” to 1/4” (3 mm to 6 mm) thick DURUS® Plaster Basecoat. A colored synthetic plaster coating was then applied on the DURUS® base. By employing the DURUS® method, the conventional nuisances of noise, dust, and debris removal were eliminated.

This DURUS® method saved the hotel owners over $3 million and no room nights were lost as the hotel was in full operation with virtually 100% occupancy during the resurfacing. The project is now complete and the owners are extremely pleased with the results.

DURUS® Cement Wash

DURUS® Cement Wash is applicable to precast and cast in situ concrete buildings. A 17-story apartment building in Hawaii that was only five years old had painted surfaces that was peeling off. The ordinary cement wash basecoat used was not water tight allowing moisture penetrate this surface which resulted in spalling and deterioration of the cement wash and paint surface.

As a solution, the existing paint and cement wash was removed by water blasting and DURUS® Cement Wash Basecoat was applied to seal the base concrete from moisture penetration. The DURUS® coating products produce a long lasting water resistant surface.
