Our training on A143-2 follows the worksheet DWA-A 143-2:2015 and covers pipe relining and short pipes.
In the existing stock, regular rehabilitation of sewer pipes is required that deviate from the shape of the circular profile or standard egg-shaped profile: dragon or hood profile, stretched or pressed egg-shaped profile, mouth profiles, channels with dry weather gutter (TWR). As an engineering service provider, we design liners and short pipes for such geometries using FEA.
