Performing coating removal on a variety of surfaces and structures is something that Rampart has been successfully doing for more than 25 years.  We have the ability to easily and effectively remove coatings, stains, and other deposits in an environmentally-friendly way.

By using powerful diesel engines and pumps, Rampart forces water through high-pressure lines and then through tiny, rotating nozzles to generate “ultra-high” pressures–up to 36,000 psi.  When released from the cleaning heads mounted on our Blaster trucks, BlasterVac trucks, hand lances, and other equipment, the pressurized water passes through the nozzles at high velocity–at speeds up to 1,500 miles per hour–and friction heats it to approximately 140° F.

That hot water, alone, is effective for removing stains and deposits, like gum, dirt, debris, oil, grease, jet fuel and other items that stick to asphalt, concrete, or metal surfaces. The combination of high pressure and hot water is so effective that no chemical or detergent additives are needed: only clean, potable water.

By controlling the angle of the high-velocity spray in a consistent manner, we are able to throughly clean the surface in a harmless and nondestructive manner. Homeowners are more likely to damage their concrete driveways and sidewalks with 3,000 psi, retail power washers than Rampart is with its large-scale, robotic processes operating at twelve (12) times the pressure.

Within our surface cleaning and coating removal division, we have established a large rubber removal business.  Our process cleans built-up airplane tire rubber from airport runways without damaging the surface. Because of friction between the rubber tires and the runway, during each takeoff and landing, a little bit of rubber is left behind–just like any other sort of skid mark. As the rubber builds up on the surface, the necessary friction is lost and both stopping time and distance increase–thereby leading to potentially unsafe conditions.

Rampart’s nondestructive cleaning techniques are effective and economical ways to clean hard surfaces like concrete, metal, asphalt, and aggregate.  We can remove old coatings, like paint and membranes (sealants), on surfaces and in cracks and expansion joints. That allows the proper application of new sealants and paints to penetrate the cracks and protect the concrete from the damaging effects of salt and chloride penetration.
