UNISORB® WTF™ Non-Shrink Grout

Originally developed for the critical grouting of Wind Turbine Generator base structures to their foundations, Unisorb® WTF™ Non-Shrink Grout is a cement-based, non-shrink grout that develops ultra high compressive strength in a short period of time. Unisorb® WTF™ Non-Shrink Grout is uniquely suitable for manual placement at a stiff consistency where it is not possible to utilize traditional forming methods. Unisorb® WTF ™ can be the key to significantly shorter erection times. Unisorb® WTF ™ exhibits the following features:

• Pre-mixed
• Extra high strength (28 day strengths in excess of 12,500 psi)
• Non-shrink
• May be manually placed at stiff consistencies eliminating traditional forming requirements
• May also be placed at flowable consistencies using traditional forming methods
• May be pumped and vibrated
• High yield
• Meets ASTM C 1107

High Quality, Non-Corrosive, Non-Shrinking

Unisorb® WTF™ Non-Shrink Grout is composed of several carefully blended size ranges of pure silica sand, the best quality high early curing Portland cement and a proprietary controlled expansion compound.

Unisorb® WTF™ Non-Shrink Grout is chloride-free, has controlled expansion and will not shrink below its original mixing volume after the recommended water ratio is added. Controlled expansion ensures a full bearing contact between machine base and foundation.

Important Advantages

Because of its unique formulation Unisorb® WTF™ Non-Shrink Grout can be mixed at significantly lower water ratios yielding a product that can be formed by hand and in many cases does not require traditional grout forms for placement. If an ultra high strength flowable grout is required the water to dry powder mixing ratio is simply adjusted to yield a flowable material.

V-1® Non-Shrink Grout exceeds ASTM C 1107 and Corps of Engineers Specification for Non-Shrink Grout CRD-C 621. ASTM and CRD test results are available on request.
