Selection Guide

ribbed flat

Recommended for construction joints or contraction joints, which are stable and with minimal movement.

Ribbed Flat is popular for stationary joints, offering excellent sealing capabilities. The ribbed structure strengthens the connection between the waterstop and the concrete, increasing its effectiveness in preventing water infiltration and enhancing waterproofing performance.

base seal

Recommended for expansion joints, which experience significant movement due to temperature fluctuations and changes in the volume of the concrete.

Ribbed with centerbulb is the most versatile and efficient waterstop currently available . The centerbulb adjusts to lateral, horizontal, and shear movements, with larger centerbulbs accommodating more substantial shifts. The ribbed design, combined with the centerbulb, enhances the waterstop’s bond with the concrete while increasing its flexibility as the concrete moves, ensuring maximum waterproofing effectiveness.

dumbbell

Recommended for construction joints in standard applications such as water tanks and underground culverts.

Dumbbell serves as an alternative for non-moving joints. The large bulbous ends are designed to enhance the connection and flexibility between the waterstop and the concrete. However, this design may face challenges at complex intersections or transitions, where greater flexibility and shaping capability are required.

ribbed with centerbulb

Recommended for construction joints, which are either stationary or have minimal movement, featuring a flat edge.

Base Seal is perfect for joints in floors or retaining walls and can be easily shaped. Despite some limitations at transition points and intersections, this design is the simplest to install. Its thick, raised ribs ensure a strong connection between the waterstop and the concrete.

base seal with centerbulb

Recommended for expansion and contraction joints, which experience movement and changes.

Base Seal with centerbulb adjusts to lateral, horizontal, and shear motions, with larger centerbulbs handling more significant movements. However, Base Seal waterstops have some limitations at intersections and transition points.

dumbbell with centerbulb

Recommended for construction, contraction, and expansion joints in standard applications, particularly at grade-level joints in walls or slabs.

Dumbbell with Centerbulb design provides more effective sealing for joints that experience movement. However, for larger joints or those with significant movement and complex structure, the dumbbell design may not meet the higher waterproofing demands compared to more specialized designs, such as ribbed with centerbulb.
