All Types of Waterstops to Prevent Liquid Leaking. Waterstop plays an important role in waterproofing a concrete structure, especially joints, the weakest part which is liable to leakage of water or chemical liquids. So waterstops are designed as a fluid-tight diaphragm embedded in or running along the joints to solve these problems.

Simply lay the waterstop directly on the compacted sub-grade, place and finish concrete, and create control joint using saw cut or other method. The base seal provides a permanent, life-of-structure seal at the bottom of the joint. Base seal is suitable for construction, contraction (control), and expansion joints.

Krytonite™ Swelling Waterstop. Krystol Waterstop System. Krytonite Swelling Waterstop is a synthetic rubber waterstop that uses swelling pressure to seal concrete construction joints and stop water. Krytonite has superior swelling pressure and performance that stops water better than bentonite and competing swelling waterstops.

Compared with waterstop, it can be used in various irregular seams, especially between different materials, wet, pile head and other parts. And it also can be used in vertical surface without sag. Water-swelling sealant can be divided into two kinds according to the swelling ratio: PJ220 and PJ400.

BASE SEAL WATERSTOPS . Base seal type waterstops, sometimes referred to as externally placed waterstops, are installed prior to placement of concrete and reside either on a prepared subgrade, mudslab, or on vertical formwork. Base seal waterstops are positioned such that only the ribbed side of the waterstop engages the concrete.

ment. Base Seal waterstops have some limitations with transitions and intersections. Dumbbell shapes are an alternate profile for non-moving joints. Consider ribbed shapes for better sealing characteristics. Base Seal is ideal for slab-on-grade joints or backfilled walls and are easy to form. Base Seal waterstops have some limitations with ...

Greenstreak PVC Waterstop is a flexible PVC waterstop for joint waterproofing. Embedded in concrete, across and or along the joint, waterstops form a watertight diaphragm that prevents the passage of liquid through the joint. Sika Greenstreak's PVC waterstop is suitable for potable water contact and meets NSF/ANSI Standard 61.
