CertainTeed has introduced the Certaform Leave in Place Form, which can be used with Form-A-Drain when forming foundation footings in areas where building codes require only one-sided drainage. Composed of 100 percent recycled material, it is engineered to be left in place along the foundation footing. Available 6 in. high and 12 ft. long, it is made from polyvinyl chloride and weighs 0.53 lbs. per foot.
