The choice of a polyurethane material provider for your geotechnical contracting business is a critical decision with far-reaching consequences. In addition to top quality concrete and soil repair material, a premier provider will offer reliable high-performance equipment, rock-solid tech support, extensive training resources and even marketing assistance.

Polyurethane Materials

All polyurethane materials are not created equally. Make sure you ask around the industry to see which materials are the most reliable.

Characteristics of High-Quality Materials

• 100% virgin (do not contain recycled polyurethane).
• Easy on your reactor (does not create high-pressure that wears out your equipment).
• Unlikely to catch fire (yes, some sub-par materials out there will char or catch fire while setting up).
• Capable of bonding to concrete.
• Strong and durable after they set up.
• Approved for contact with potable (drinking) water after curing.

Rigs and Equipment

The quality of your geotech rig is not something you want to compromise on. A premier provider will offer state of the art rigs set ups, customized to fit your exact needs. You’ll want multiple door options (side door, choice of barn door vs ramp door), multiple power outlets and slide-out equipment options. These features allow for maximum flexibility in all types of job situations. In addition, a well-insulated rig allows for operation in a wide variety of climates.

Your pumps, air compressors and slab lifting guns need to be reliable as well.

Characteristics of High-Quality Equipment

• Easy to use (not overly complicated).
• Easy to maintain (easy to clean, not a lot of complicated parts to replace all the time).
• Reliable, reputable brands.

Tech Support and Training Resources

A major differentiator separating serious material manufacturers from the rest is the availability of on-the-job technical support and service. A premier provider will offer field service to assist customers on challenging jobs. Phone support should readily available as well, with support techs ready to answer questions when you need the answers. You will also want to look for comprehensive training resources on material installation, equipment use and maintenance, and estimating/billing jobs. A good combination of online videos and articles, training literature and live events is the sign of a manufacturer dedicated to educating their customers.

Marketing Assistance

Look for a provider offering robust marketing assistance. Geotech contractors have many marketing needs, including website content (illustrations, photos, descriptive text), videos, vehicle sign design, advice on lead capture, etc. A manufacturer willing to go the extra mile in this department can help give you an edge of the competition in your market.

Do Your Own Research, Make Your Own Choices

Did we just describe Alchemy-Spetec in the paragraphs above? Of course we did. This is the Alchemy-Spetec blog after all. That being said, we encourage you to do your own research and contemplate your own needs in a material provider. Ask around in the industry. Seek out users of different brands and find out all you can about their experiences. If you think we missed anything in this article, let us know. We’d be happy to hear from you.

As a consultant on many deep soil geotech jobs over the years, I have found myself recommending one critical piece of equipment repeatedly: The Dynamic Cone Penetrometer (aka the DCP). I highly recommend this tool as an essential part of your Deep Lift® rig set up. As Jim Spiegel explained in his blog post on this subject, this device is used to measure the strength of subgrade soils, and can be utilized to identify weak layers of soil within a soil mass. As you can see in the video below, a hydraulic pump drops a 30kg (60lb) hammer, driving the measuring rod into the ground.

To measure soil strength, the operator counts the number of blows it takes to drive the steel rod in 10-centimeter increments. Good soil requires 10+ blows to drive the rod 10 centimeters. Anything less is typically indicative of weak soil conditions.

DCP testing is a widely accepted means of in situ testing. Due to the common acceptance of DCP testing, many municipalities and agencies are willing to pay for this service.

Here is a hypothetical scenario for DCP use:

Soil strength data is needed under a concrete parking lot before a Deep Lift® job. Multiple tests would be performed, spread out evenly over the area. For thorough testing, each DCP test would be executed to a minimum depth of 15 – 20 feet or refusal (when the hammer blows no longer cause movement.) The test results can then be compared and analyzed to find where potential weak soil conditions may be present. This allows for accurate and effective application of the polymer to address the weak layers.

DCP testing can also be utilized prior to bidding any Deep Lift® job to develop effective injection plans, as well as accurately estimate material usage on projects. With that said, it’s not always possible or practical to perform pre-bid testing. When pre-bid testing is not performed, it would still prove highly beneficial to perform DCP testing prior to injection. I have personally encountered many situations where injection plans have been drastically altered after test results were analyzed (injection depth was added or subtracted, the weakest layers were identified, etc.) The Dynamic Cone Penetrometer is a portable tool which can easily be used in many locations where other testing methods are not feasible and it provides valuable insight into the soil conditions that need to be improved.

When two adjacent slabs are touching, there is a high likelihood of them being bound. This is definitely something to look out for on slab lifting jobs for a variety of reasons.

Bound Slab Basics

If you try to lift a slab that is bound to an adjacent slab, you could end up:

• Lifting a part of the slab that you did not intend to lift.
• Cracking the slab.
• Lifting the adjacent slab unintentionally.
• Wasting valuable extra material trying to lift a slab that is stuck.

Even if a seam between two slabs or a control joint (a joint meant to break when the slab is under pressure in order to prevent cracking) is already loose - it's still best to run a saw through it just to be sure before attempting to lift. A concrete saw blade is 1/8-inch wide. When you cut between slabs, you are giving them a 1/8-inch gap to ensure smooth movement.

Pros and Cons of Two Types of Concrete Saws

There are two types of concrete saws to choose from when stocking your arsenal of slab lifting gear. Here are the pros and cons of each…

Circular Saw

PROS

• Fast cutting rate.
• Low operating cost.
• Easily sourced blades.

CONS

• Requires overcuts (the blade typically extends 4 to 6 inches past the edge of the slab).
• Requires a wide berth. Cannot cut up against edges of walls and structures.

Concrete Chainsaw

PROS

• Doesn't require overcuts.
• Can cut up against the edges of walls and structures.
• Can cut up to 12 inches deep.

CONS

• Has a high operating cost (chains and bars tend to be expensive).
• Low cut footage per bar and chain compared to circular saw blade.

As the Director of Technical Services for the Leak Seal division at Alchemy-Spetec, I often find myself assisting customers with some interesting jobs. Such was the case when I was called in to consult with a contractor who was sealing a leak in a historic district below-grade, multi-course brick wall. As is often the case with below grade, historic spaces, water infiltration was unsightly, gave off a musty odor, and was damaging to finishes. This was a very old brick wall, approximately 8 x 15 feet in size and at least three courses thick. The owner wanted to find a way to waterproof this vintage brick structure while at the same time preserving its unique appearance. In addition to the water flow issue, the leaks were causing mold/mildew on the walls.

We proposed injecting Spetec PUR AG200, a high-strength elastic acrylic injection resin, into the cementitious grout between the bricks where the water was migrating through. In order to monitor the efficacy of this leak seal job, we employed the QP Factor® leak seal testing and quality control system. As stated on our website, “The QP Factor® system offers quantifiable water flow, pressure, and flow/pressure metrics before and after leak seal injection that will provide clients, contractors, and design professionals the industry’s first patented method for proving Leak Seal® success.

The method of testing requires additional drill holes to be placed at pre-determined locations along the crack, joint, or substrate being sealed. Prior to injection of chemical grouts such as Spetec PUR F400, Spetec AG200, or Spetec PUR GT500, the test hole is connected to a digital touch-screen device that is calibrated to provide water pressure, flow, and flow/pressure information that is extractable in excel format from a convenient USB port.”

We ran the QP Factor® system on three test areas in the wall before beginning the injection process. This revealed to us the amount of water that was flowing through the wall. After injecting Spetec PUR AG200 into the existing cementitious grout around the bricks in two of those test areas, we ran the QP Factor® tests again and realized that wouldn’t have to inject the third area due to the efficacy of the Spetec PUR AG200.

In addition to stopping the water flow, sealing the leaks made it possible for the bar owner to keep the walls clean in appearance. See the treated area of the brick wall vs a non-treated area.

Why Use Polyurethane for Seawall Repair?

Non-Intrusive Application
Polyurethane can be injected through pipes directly into voids and loose sandy soil using small portable equipment.

Proven Solution
Seawall repair resins are used extensively seal cracks, voids and defects as well as for filling voids and stabilizing the soil.

Creates an Impermeable Mass
Polyurethane seals leaks along the wall, fills the voids that have occurred, and mixes with the soil to form a solid, impermeable mass.

What Are the Results of Polyurethane Seawall Repair?

Long Lasting Solution
Alchemy-Spetec seawall repair resins cure to a strength greater than crystalline bedrock. Combined with proper drainage, this method can greatly extend the life of your seawall.

Water Tight Seawall
The resin reacts with water or moisture in the soil and expands to fill voids while it permeates sandy soil to form a solid, strong, watertight mass.
