Slab Lifting Overview

Over time, concrete surfaces settle and need to be lifted and leveled. Polyurethane foam is an effective slab lifting method. The process involves injecting polyurethane into voids beneath the concrete surface to lift and level the slab. Cost-efficient and effective, this method has become increasingly popular over time.

Slab lifting with polyurethane is non-invasive, quick, and causes minimal disruption to nearby areas. Small holes are drilled into the concrete and foam is injected through them. The foam expands, filling voids beneath the slab and lifting it back to its original position.

So, you have another clog in your boot? Well, your grain elevator boot that is. This means shutting down to clean your grain elevator. Which means loss of production, loss of grain, and delays. Drains and sump pumps clog and can be unreliable. 

A grain cooperative in Washington state contacted Kodiak Concrete Lifting. Alchemy-Spetec's Leak Seal Division Director of Technical Services, Charlie "The Grout Geek" Lerman, met Kodiak on-site and inspected the leaking boots in question. One was poured concrete and the other was poured concrete with a metal interior liner. Both had multiple areas of water intrusion and sumps that were not able to handle the leakage. Charlie worked with Kodiak on developing a grouting plan and an estimate for the co-op.

Powerful Polymer

Spetec PUR HighFoamer was the ideal grout for forming a positive side waterproof barrier known as a curtain wall without having to excavate and with very little downtime.

Spetec PUR HighFoamer is a highly expansive grout (40x-50x) and it is also NSF 61-approved for potable water use.

Painless Procedure

Pumping polyurethane grouts is done with a modified airless paint sprayer. Since this pump is lightweight, it is easy to mobilize in remote or difficult-to-access locations. Normally, the technicians would set up a 2’ on-center grid pattern for curtain wall grouting. With the elevator equipment layout, they had to adjust the spacing. By pumping hole to hole they ensured water-tight grout coverage even with the irregular port spacing.

Rapid Result

A few weeks later, Charlie Lerman and Kodiak met back on-site for the installation. While working in a grain elevator pit and working with urethanes can be a bit messy, the injections went well and the water intrusions were stopped in both pits on time and under budget.

Unstable soil can be a real nightmare. Existing structures, new construction projects, and excavation projects alike require strong supporting soil. Rain, freeze-thaw cycles, erosion, poor compaction, and excessive water saturation all pose a threat. The planet consists of 70% water and 30% land. Unstable soil is everywhere.

Contractors use Alchemy-Spetec structural polymers to strengthen soil supporting existing structures, provide a firm foundation for new construction, and prevent soil collapse during excavation projects. When cured, these polymers are stronger than crystalline bedrock. Alchemy-Spetec structural polymers are environmentally safe and certified to NSF/ANSI/CAN 61 standards for contact with drinking water.

Repair Cracks and Joints in Concrete

AP SlabSeal 142 is a high-performance, single-component, moisture-cure, ultra-low modulus silicone sealant. It is ideal for sealing cracks and joints in concrete. This includes the most demanding dynamically moving joints. AP SlabSeal 142 is often used to put the finishing touch on concrete slabs after they have been lifted and leveled.

Features

• High-performance non-slump, one-part, moisture-curing, room-temperature vulcanizing (RTV).
• 100% silicone sealant specifically formulated for concrete joint applications.
• Protects joints and cracks from water infiltration.
• Ultra-high elongation.

Benefits

• Exhibits excellent unprimed adhesion to concrete, steel, and most other construction substrates.
• Will maintain its integrity on joints with movement.
• Unaffected by sunlight (ultra-violet rays), ozone, temperature extremes, rain, and snow.
• Clean appearance is ensured through professional installation.
• Long service life, under normal conditions it will maintain its physical properties between -60°C to 200°C (-76°F to 392°F).

A major culvert restoration project was recently completed by Geotech Services Inc. in Ohio. The Este Ave culvert is a concrete storm sewer that runs about 1000 feet from 4861 Este Ave to Mill Creek. The culvert includes 200 pipe joints, the majority of which are not watertight, and is 108 inches in diameter. A few of the sealed joints in the culvert have failed, leading to enhanced infiltration at downstream joints. The groundwater infiltration ranges from modest seepage to major leaks. Although there aren't any voids easily seen at the surface, it's expected that some channeling has happened along the pipe's bottom. In 2008, grout was injected to seal several joints near the intake and to fill voids around the outside of the pipe. Controlled density fill was then used to fill voids at the surface around the wing wall. Since that time, the wing wall has remained stable. Unfortunately, the culvert's sealed joints have degraded, leading to more infiltration at downstream junctions.

Powerful Polymer

Geotech Services used Spetec PUR GT500 to seal all the pipe joints in the culvert and to fill voids around the outside of the structure. Spetec PUR GT500 is NSF/ANSI 61 approved for contact with drinking water. This single-component polyurethane resin is designed to penetrate and seal off leaks in cracks, joints, and pipe penetrations. As a hydrophilic polyurethane, it chases down water and gets into the microstructure of the concrete, forming a flexible seal and a mechanical bond with the wet concrete.

Painless Procedure

Every joint in the culvert's bottom half was leaking and allowing groundwater to seep in. Geotech Services drilled one injection hole in the middle of the culvert joint at the bottom and injected the GT500 until the joint was completely sealed. Additional holes were drilled, based on how the material was traveling. About 3500 gallons were injected overall.

Rapid Result

The entire 1000-foot culvert was sealed in just under 30 days.
