Hycrete Benefits

Proven in Difficult Conditions

Because Hycrete waterproofing and corrosion inhibition solutions are poured with the concrete, they are flexible and able to fit into complex shapes. With full service for Hycrete System W, your project can be successfully waterproofed even in areas where waterproofing is usually difficult, if the application is approved. Examples include:

Waterproofing shotcrete applications
Uneven surfaces
Penetrations
High water table
Salt water

Waterproofing Shotcrete Applications

Shotcrete waterproofing is often challenging. Tough membranes have to be used to minimize damage from the pressure of pneumatically projected concrete, and they have to be held in place with strong systems. These solutions are not always successful. Along with poor consolidation often found in shotcrete, there are often numerous penetrations and voids which can lead to leaks and corrosion. With Hycrete System W, there is no need for a separate membrane. The waterproofing is inside the concrete. With guidance on mix design and quality assurance on site, shotcrete consolidation is improved. The result is waterproof shotcrete. This is a great way to value engineer your shotcrete wall*.

Uneven surfaces

Blasted rock, caissons, soldier piles – there are many situations where a lot of surface preparation to uneven surfaces is required before applying waterproofing membranes. In some cases an additional layer of concrete is applied, and in other cases timber or other permanent formwork is used. These are time-consuming and costly. With Hycrete waterproofing solutions, concrete can be poured directly on the clean uneven surface, without need for surface preparation, saving time and money.

Soldier piles and lagging are uneven and may require considerable preparation before membranes can be applied. Hycrete waterproofing products can be used without surface preparation or risk of punctures.	A considerable amount of preparation is usually required when waterproofing caissons. Hycrete waterproofing products can be used without time-consuming and expensive surface preparation.

Penetrations

Tie-backs, rakers, and other penetrations are notoriously difficult to waterproof. They require special details, which are time-consuming and often leak. With Hycrete waterproofing solutions, waterproofing of penetrations is made simpler.

With Hycrete integral waterproofing, penetration details are a lot more simple	Penetrations through membranes are complex to detail and to install, and often the source of failures in waterproofing

High Water Table

When you are building in the water table, leaks can be devastating. For select applications, Hycrete System W can provide membrane-free, leak-free waterproofing even below the water table, reducing cost, time, and risks*.

Salt Water

If your project is in brackish or salt water, there is a risk of corrosion. Hycrete products all protect against corrosion in several ways. Hycrete waterproofing admixtures are dual-action corrosion inhibitors, which (a) reduce the permeability of concrete, so water and corrosive salts are less able to penetrate the concrete, and (b) form a protective layer around rebar, so the corrosive agents are less able to attack it. They also help close small cracks. In slightly cracked concrete, they outperform calcium nitrite and high performance concrete in corrosion inhibition. They may be used to replace both the coated rebar and the corrosion inhibitor or permeability reducer. They may also be used in addition to coated rebar and supplementary cementitious materials for extra protection. Find out more about how Hycrete admixtures work.
