    Diving into chemistry

    Most common problems with pool water chemistry can be attributed to five factors: free available chlorine residual, total chlorine residual, pH, total alkalinity, or calcium hardness. Fortunately, each factor can be corrected easily through careful monitoring, testing, and managing.

    Porous pavements move stormwater efficiently

    Porous asphalt pavements with stone recharge beds are rapidly gaining popularity as major components of a storm-water management system. These pavement/stormwater systems are designed to reduce peak and total volume of runoff and also are effective in removing total suspended solids.

    Repair or replacement

    The key is understanding the asphalt life cycle and how roadways deteriorate. Combine this understanding with an effective pavement life-cycle management (PLCM) approach and roadway managers can save thousands, if not millions, in roadway repair or replacement costs.
