Twinwall Drainage Junction - 45 Degree x 300mm x 300mm BlackTWINWALLTwinwall drainage is predominantly used in stormwater applications where the strength of the pipe is key, such as under roads, sports pitches and landscaped areas. Because of their high compressive strength they can also be buried much deeper than standard PVC drainage pipes as they can easily support a greater weight of soil backfill.There are two options when connecting fittings to twinwall pipes; they can either be loose jointed or sealed joints. Sealed joints, used with unperforated twinwall pipes in stormwater drainage applications, require separate seals to be inserted over the pipe prior to the fitting being connected
