This type of construction job entails pouring concrete on a horizontal plane, creating a perfectly flat and smooth surface. Concrete flatwork installations are popular with property owners due to the material’s strength and decorative options. Concrete Stormwater detention systems manage and control the volume and discharge timing of stormwater runoff. Our detention solutions temporarily store runoff in large underground precast concrete chambers before releasing it at a controlled rate. This helps to mitigate many of the harmful effects of high volumes of stormwater runoff, such as erosion and flooding.
