CONRETE MANHOLE ADAPTERS (Waterstops) (CMA)

Help eliminate leaks around pipe entering manhole walls, yet are flexible enough to permit pipe movement without destroying seal integrity. It is particulary usefull for pipe to which concrete will not adhere, such as plastic pipe.

The CMA, made of elasomeric plastic, is corrosion-proof and is unaffected by acid or alkali. However, the CMA is subjected to any various conditions beyond the manufacturers control, and it`s effectiveness as a seal is directly related to the quality of the grout, workmanship, and field conditions under which it is installed.

CMA`s are available for 4, 6, 8, 10, and 12" (101, 152, 203, 254, and 304mm) pipe.

CMA`s in sizes larger than 12" (304mm) are also available.
