Dewatering & Stabilization
Dose Rate

Megaslab, a new innovation in the concrete industry, was set to be laid in its first major project – a 48,000 SF headquarter expansion. Due to tight timelines & wet, unworkable soil, Calciment® LKD was chosen as the solution to quickly dry & stabilize the soil to keep the project on schedule.


Project Overview

  • MEGASLAB™ is a new joint-less, impermeable concrete system using nanotechnology.
  • Calciment® LKD was used to quickly dry and modify the soil
  • Calciment® LKD allowed the project to continue in adverse weather conditions, improved bearing capacity, and eliminated the need for aggregate, resulting in cost savings.

Jason Adams, of Sinclair Construction Group, and Sylvester Schmidt, an industry expert, recently developed MEGASLAB™ as the first ever jointless, impermeable concrete system utilizing nanotechnology. Their concrete mix utilizes this sophisticated nanotechnology, paired with a proprietary blend of durable and flexible admixtures and is the first major disruption the concrete industry has seen since Portland Cement was created in the 1800s.

The elimination of control joints and unmatched durability brings down total project costs, reduces maintenance issues, and extends the overall life of the concrete. Calciment® LKD was introduced into the market over twenty-five years ago and has been used to facilitate construction and support slabs on thousands of projects.

A nationally recognized product developer teamed up with Sinclair Construction Group and Mintek Resources on a 48,000 SF headquarter expansion project in NE Georgia. MEGASLAB™ was ready to tackle their very first project of scale and show the impact this new solution would have on the industry.

The Challenge

The project timeline required MEGASLAB™ to be poured in November 2018 during the second wettest winter on record in NE Georgia. This timeline proved difficult, as the in-situ material was unworkable and unable to achieve the bearing capacity required to support the building. The three options were to remove the poor soil and import aggregate, chemically treat the building pad subgrade, or wait until the weather improved. As the cost of cut-and-fill and postponing the project was prohibitive, a solution was needed that would dry out the soil quickly.

The Solution

While reviewing options to accelerate drying of the in-situ soil, MEGASLAB™ discovered Mintek Resources, a company that supplies a variety of solutions that assist with drying, modifying, and stabilizing wet, weak, unworkable soils in construction applications. Mintek’s flagship product, Calciment® LKD, has been used for decades on projects across the U.S. to keep projects on track by offering fast drying and improved workability of native soils. This economical reagent contains a unique blend of lime and pozzolans to allow fast dewatering, PI adjustment and strength gains for long-lasting pavement structures.

After reviewing all of the options, Calciment® LKD was selected for this inaugural MEGASLAB™ project due to its high economic value versus alternative methods and its ability to quickly dry and modify the soil to keep the project on time and on budget. Calciment® LKD was spread at a 5% dose rate and mixed to a depth of 12” with a road reclaimer.


Calciment® LKD allowed the project to continue in the midst of a cold and wet fall season. However, the results didn’t stop there. In a typical warehouse slab design, aggregate is placed at a predetermined thickness on the building pad prior to pouring a concrete slab.

However, after Calciment® LKD was incorporated into the subgrade, the bearing capacity was improved to the point that the aggregate was value engineered out of the project – providing a significant cost savings to the overall project!
