SEALING SAWCUT CONTRACTION JOINTS

With

Hydrophilic Adeka Waterstops

ADEKA WATERSTOPS make the job of sealing contraction joints easier and more secure.

The choice of product depends on expected expansion / contraction and joint width. Either ADEKA P-201 OR ADEKA KBA-1510FP is an appropriate product to use depending on conditions.

Use KBA-1510FP when joint width is between 1/4? ~ 3/8? and expected movement is less than 1/8? (approximately).

P-201 has more expansion ability and will function in a wider range of conditions.  Use P-201 when joint width is between 1/4? ~ 1?.  Amount of allowable movement depends on initial joint width.  If joint width is 1/2?, allowable movement is approximately 1/4?.  The wider the initial joint width the more movement it can withstand.  

Although P-201 has excellent adhesion qualities, we don’t depend on adhesion to stop water.  Water penetration is stopped by pressure developed by containing expansion of the product.  Therefore loss of adhesion (most products will lose adhesion over time) is not a problem.
