stiff , short-bristle brush, using moderate pressure or pressure-wash using a 40 tip and 1,500-2,500 psi for pressure-treated wood and composites. Use 500-1,000 psi for Cedar and Redwood. Move lengthwise with boards to avoid cut marks across grain. Either
25/4/2007· I will suppose that the 100 meters is elevation change and not distance. If it is distance, resubmit the question and state the elevation and the distance. Ideally, cold water could be lifted (by suction) only a little less than 11 meters (33 ft.) by ANY device or means.
Move Concrete Waterproofing Off-site There are an increasing nuer of project delays with contractors placing great importance on worker safety and availability. Learn how companies are using an alternative proven technology to move concrete waterproofing off-site thereby reducing site-activity and accelerating construction schedules.
