Advance Products & Systems End Seal

Advance Products & Systems End Seals outperform the costly and labor intensive brick and mortar method of sealing casing ends. While soil stress and pipe movement cause mortar to crack, the APS products move with the pipe insuring the integrity of the seal. And, unlike link-type sealing blocks that are limited to carrier/casing differential and can only be used on a concentric profile, the APS seals are totally flexible. APS offers four types of end seals which can accommodate any combination of pipe sizes.
