What is High Lift and Low Lift Grouting?

High Lift and Low Lift grouting are terms used in building codes to define the method of placing grout in reinforced masonry walls. Codes allow the contractor to choose either method unless the structural engineer requires one or the other. Low Lift grouting may or may not require the use of inspection or clean-out openings. High Lift grouting will require inspection openings spaced no more than 32 inches apart or at each rebar location.
Advantages of High Lift Grouting

Smart Masonry Systems has recognized the value of the High Lift grouting method as referenced in ACI 530. Mason Contractors can easily choose the High Lift grout method to increase block production and project efficiency. The following demonstrates the obvious cost advantages of choosing the High Lift grout method over Low Lift grouting:

Commonly Asked Questions

Smart Masonry Clean-Out SystemDoes The Smart Masonry Clean-Out System require precision block openings or cell widths?

No. Smart "T-Bolts" are designed to wedge against the inner shell face of a block opening from 1 inch to 4-1/2 inches wide. The Smart "T-Bolt" can be rotated any degree to accommodate a narrower shell width. We recommend that you order inspection block from your block manufacturer or saw cut your inspection openings. Hammer cutting block is not recommended since it produces block fatigue, produces excessive debris and wastes block units.

Do you need special tools for the Smart Masonry Clean-Out System?

No. The Smart "Nut" is designed to be hand tightened.

What if the specifications restrict grouting to the low lift method?

Many engineers feel that the use of plywood and other non-transparent covers can lead to unfilled or unconsolidated grout cells. Submit the Smart Masonry Clean-Out System to the Engineer and chances are you will be able to switch to High Lift grouting.

What about Tooled finished walls?

Many contractors hide the clean-out opening behind bottom of wall base boards. Building codes allow a minimum clean-out opening of 3 inches by 3 inches.

The Smart Masonry Clean-Out System is a revolutionary system used to form Clean-Out Covers for High Lift grouting. It consists of a "T-Bolt," a re-usable "Nut" and a re-usable transparent "Window." The "T-Bolt" and "Nut" are made from hard ABS plastic. The transparent "Window" clean-out cover is made of poly carbonate, an extremely durable material commonly used in jet fighter canopies. While the "Nut" and Window" are re-usable, the exposed portion of the "T-Bolt" easily breaks off after removal of the "Nut" and "WIndow" to provide a fast, clean, professional and economical means of forming reinforced masonry clean-out covers.
