The Krystol Waterstop System is used to permanently waterproof concrete construction joints, pipe penetrations, tie-holes and control joints. The Krystol Waterstop System works where other waterstops routinely fail. Kryton is the only integral waterproofing company that offers fully integrated concrete waterproofing solutions.

How it Works

The Krystol Waterstop System is comprised of Krystol Waterstop Grout, Krystol Waterstop Treatment, Krytonite Swelling Waterstop and Kryton’s Crack Inducing Waterstop. These products are used in a variety of ways to waterproof all construction joints and details found in concrete construction

Construction Joints

Single Protection: Improved waterproofing performance over common swelling waterstops

Superior swelling pressure and performance that stops water better than bentonite and competing swelling waterstops.

Usage: Horizontal and Vertical Construction Joints

Products: Krytonite Swelling Waterstop (secured w/ Krytonite Adhesive)

Features: Exceptional swelling performance (+1000%) • Proven to stop at least 8 bar of hydrostatic pressure • Fills gaps, voids and contours in concrete to stop water from passing • Maintains cohesive state after repeated wet / dry cycles

Note: like all single protection waterstops, outboard rebar is NOT protected.


Double Protection: When a permanent, long term, hydrostatic waterproofing solution is needed

Superior swelling pressure and performance combined with Krystol technology delivered through a slurry treatment that ensures permanent waterproofing protection

Usage: Horizontal and Vertical Construction Joints

Products: Krystol Waterstop Treatment & Krytonite Swelling Waterstop (secured w / Krytonite Adhesive)

Features: Double protection against water • Protects outboard facing rebar • Preformed material, easy installation • Exceptional swelling waterstop performance • Immediate waterstop

Krystol technology delivered through an internally placed, triangle shaped, waterstop and a slurry treatment that ensures permanent waterproofing protection

Usage: Horizontal Construction Joints

Products: Krystol Waterstop Treatment & Krystol Waterstop Grout

Features: Double protection against water• Protects outboard facing rebar • Easily conforms to rough joint surfaces • Easy/flexible installation • Difficult to damage after hardened • NSF 61 certified

Krystol technology delivered through a slurry treatment and external waterstop that ensures permanent waterproofing protection

Usage: Horizontal and Vertical Construction Joints

Products: Krystol Waterstop Treatment & Krystol Waterstop Grout

Features: Double protection against water • Protects outboard facing rebar • Keyway can be filled anytime after removing form • Easy/flexible installation • Eliminates difficulties around congested rebar • NSF 61 certified


Triple Protection: Use on high risk, critical projects

The ultimate construction joint. Superior swelling pressure and performance combined with Krystol technology that is delivered through a slurry treatment and an external waterstop that ensures permanent waterproofing protection

Usage: Horizontal and Vertical Construction Joints

Products: Krystol Waterstop Treatment & Krystol Waterstop Grout & Krytonite Swelling Waterstop (secured w/Krytonite Adhesive)

Features: Triple protection against water • Protects outboard facing rebar • High-risk waterproofing • Immediate and permanent joint protection

Pipe Penetrations
