Contractor Training • Spring 2026
Learn when and how to use single-component polyurethane resins — so you can read soil reports, choose the right product, and confidently sell stabilization projects from solar fields to DOT road work.
Your Instructor
VP of Sales, Alchatek
Andy Powell brings years of hands-on field experience with single-component polyurethane applications. He lived in Florida during the company's breakout years in permeation grouting, working alongside contractors on sinkhole remediation, DOT road stabilization, and large-scale soil permeation projects — including NASA's Vehicle Assembly Building at Cape Canaveral.
In this session, Andy walks you through the full single-component product line — AP 600, AP 700, and AP 720 — and shows you how to read soil boring reports, identify permeable soils, and select the right product for every application from elevator pits to solar fields.
What You'll Walk Away With
Single-component polyurethane opens applications that two-component foam can't touch. This session gives you the technical foundation and real project numbers to sell and deliver single-component work.
Understand N values, SPT blow counts, sieve analysis, and the number 200 fines percentage so you can evaluate whether a site is a fit for single-component permeation before you ever show up on the job.
Know when to reach for AP 600 (ultra-thin permeation), AP 700 (expanding permeation), or AP 720 (high-expansion seawall/cutoff) based on soil conditions, application type, and project goals.
Use engineer outreach, geotech reports, and proven case studies — including NASA and Florida DOT — to position yourself for road stabilization, infrastructure repair, and commercial soil permeation projects.
The solar field case study breaks down every line — 3,750 gallons at $42/gal material cost, $337K invoiced, four days of production with two Poly Sharks. You'll leave with the math to price your own single-component projects.
Inside the Session
Session Walkthrough
Andy covers every aspect of single-component polyurethane — from soil science to field execution to job pricing. Here's the complete roadmap.
Andy opens with the fundamental question: is the soil permeable? Single-component resins permeate between soil grains — they need sandy, gravelly soil to work. Clay and silt are too fine. Understanding this distinction is the first step to knowing when single-component is the right call versus two-component foam.
The deep dive into geotech reports: Andy walks through a real Florida DOT boring log — what SPT blow counts mean, how to read N values for sandy vs. cohesive soils, what “weight of rod” and “weight of hammer” tell you about void conditions, and why the number 200 sieve percentage (fines under 12%) determines whether you can permeate the soil.
Andy breaks down the product lineup: AP 600 (37–40 centipoise, ultra-thin, for excavation walls and elevator pits), AP 700 (100 centipoise, 30x expansion, for grid-pattern compaction and water cutoff), and AP 720 (40–50x expansion, for seawalls and bulkheads). All are heavier than water, hydrophobic, and work in the water table without dewatering. The Poly Shark pump system — gas over hydraulic, two 400-foot hose reels with flow meters — lets you park on the street and run hoses to the work area.
The Cohen Building in New Jersey: a federal courthouse with deep infrastructure, heavy foot traffic, and settling walkways. Nine totes of AP 700 at 5% catalyst, pumping from depth and pulling rods up — a gallon per vertical foot. Then the elevator pit at Archer Sand in Gainesville: a 55-and-up community where you can't drive sheet pile inside a building. AP 600 permeation built the excavation walls so they could dig the pit safely.
Andy runs through the full market: DOT road stabilization in organic soils, water cutoff walls for soil dams and spillways, excavation assist for zero-lot-line buildings, foundation support next to existing structures, historic building stabilization with brick foundations, and seawall/bulkhead erosion repair. Every application where you have permeable soil is a single-component opportunity — and the work is everywhere once you know where to look.
Frank shares the NYC project: a 64-unit occupied building that was sinking, with the building department demanding evacuation. The team used single-component to fill voids at depth, then two-component on top for lifting — 220 injection points, 23 feet deep, two and a half years of work. Single-component curtain walls on both sides stopped an underground stream. It proved that single-component and two-component work together in the most demanding conditions.
The definitive single-component case study with full financials: 40,000 total H-piles, 5,000 failing pull tests. Three-quarters of a gallon of AP 600 per pile, four feet down. Material cost: $42/gallon, $157K total. Production: 1,200 piles per day with two Poly Sharks and four operators. Invoiced at $90/gallon — $337K total, done in four days. Then Hurricane Ian hit as a Category 3: out of 5,000 treated piles, only 9 moved.
The Breakers Hotel courtyard project: a seven-foot permeation wall done at 12 inches on center with multiple injection rows, engineered to resist overturning forces. Andy covers grid pattern spacing — 3–4 feet for soil stabilization, 12–15 inches for excavation walls — and the critical technique of letting the first gallon set before stacking to avoid bell-shaped columns instead of clean pillars.
Andy closes with the message that hasn't changed in years: you're already making the same sales calls — now you can offer deep soil stabilization on every one. Single-component is fast to install, proven in service for 40+ years, less invasive than excavation, requires no permits for most work, and combines with helicals, manta rays, and traditional underpinning. The NASA VAB, Florida DOT, and solar field projects prove it works at every scale.
