A form assembly for installation of paving materials has elongated form sections, each having a first side wall facing the paving material and an opposite second side wall that has a first longitudinal channel defined between brackets. A number of connector elements join adjacent elongated form sections. Anchor mounting elements have a first coupling member configured to fit into the first longitudinal channel of the form section and a second coupling member configured for coupling to a mounting anchor. Each of the elongated form sections has an upper screed contact surface orthogonal to the first side wall and wherein a first wall thickness between first and second side walls that is between the upper screed contact surface and the first longitudinal channel exceeds a second wall thickness of the form section that is between the first longitudinal channel and a base that is opposite the upper screed contact surface.
