Today, we’ll take a look at the specification Permeation Grouting with Polyurethane. The specification includes documentation on the following:

• Stabilization, consolidation, and binding of water bearing soils through permeation injection of polyurethane resin creating a solid mass of soil and rigid resin.
  
  
• Creation of a barrier in water bearing soils to reduce water migration through permeation injection of polyurethane resin creating a solid mass of soil and rigid resin.

The Alchemy-Spetec structural repair product line consists of products for joint filling, spall repair, anchoring, and bonding.

Poyurea Joint Filler

AP Joint Fill 800 is a two-component hybrid polyurea joint filler with fast reaction allowing for shave time in as little as 5 minutes. The fast reaction allows for minimal down time and facilities to be in operation quickly.  Read more...

Polyurethane Spall Repair

AP Fast Repair 850 is a zero VOC, two-component polyurethane system. The high-quality thermoset is designed for fast repair of concrete (spalls, cracks, etc.). Its low viscosity allows for maximum penetration into cracks and porous concrete. This product can be mixed with up to equal parts oven dry silica sand to increase product yield and compressive strength.  Read more...

Non-Sag Epoxy for Structural Anchoring/Bonding

AP NS950 Epoxy is a two component, non-sag structural epoxy designed to offer exceptional mechanical strength in anchoring/bonding applications. Due to its high bond strength to concrete, it is ideal to use for anchoring threaded rod or rebar dowels. The consistency of AP NS950 EPOXY is good for capping for crack injection or general surface repairs. AP NS950 EPOXY is 100% solids, VOC free and Butyl Glycidyl Ether (BGE)* free.  Read more...

Low-Viscosity Expoxy for Structural Bonding of Cracks

Leaking concrete can be detrimental to safety and property values.  Pressure injection forces polyurethane resin into leaking cracks, joints, voids, and other defects.  After injection is complete, the polyurethane resin rapidly reacts with water to form a flexible, watertight seal.  Leaks in concrete structures can be permanently repaired with water-activated polyurethane and a few assorted leak seal accessories.

From hairline concrete cracks to gushing leaks, virtually any defect can be sealed with the Alchemy-Spetec series of leak seal resins and products.

Get ready for a thorough education in polyurethane leak seal products and applications on Wednesday, October 9th (October 10th is geotech day), 2019 at Alchemy-Spetec HQ in Tucker, GA. You’ll get hands-on training from a technical staff with decades of on-the-job experience. Registration includes both days, but we’ll take a close look at the leak seal curriculum in today’s blog post…

The schedule on Wednesday, October 9th includes presentations on the Alchemy-Spetec leak seal product line, crack injection, curtain grouting, permeation grouting, pumps & packers, leak seal accessories and municipal applications. There will also be live injection demos, product mixing demos, and open discussions for sharing job related tips and solutions from the field.

In addition, you'll get an overview of geotech (concrete leveling & soil stabilization) products and procedures!  Here's a complete schedule for both days...

• Saturating dry oakum to create a flexible gasket for sealing pipe penetrations, joints and larger defects in concrete structures.

If you’re unfamiliar with the terms hydrophobic and hydrophilic, please read the blog post Hydrophobic vs Hydrophilic Polyurethanes.  In that post we clearly explain the differences between the two types of leak seal resins…

Hydrophobic Polyurethanes:

Hydrophobic polyurethanes naturally repel water (similar to the way oil would repel water and stay separate if you were trying to mix them in a glass).  These products push water out of the area in question as they expand.  Hydrophobics are used with catalysts which allow you to adjust the set time.  They also have zero shrinkage after curing.

Hydrophilic Polyurethanes:

Hydrophilic polyurethanes naturally mix with water before curing (similar to the way gin and tonic mix thoroughly in a glass).  This characteristic allows for a very strong chemical and mechanical bond, as water helps pull the material into the pores of the concrete.  These products do not require a catalyst.  You can pump them straight out of the pail.

Click this link, Injection Grouting – Hydrophilic & Hydrophobic, to view a PDF of the specification.  It thoroughly documents the installation process for these two types of products (in our case, the hydrophilic Spetec PUR GT500 and the hydrophobic Spetec PUR F400).  These are both flexible polyurethanes.  For a copy of the specification in Microsoft Word format, please call Alchemy-Spetec at 404-618-0438.

We’re often contacted by spray foam contractors looking to add slab lifting to their skill set.  One of the first questions we’re asked is “what new equipment do I need?”  The answer is “not much”.  With just a few pieces of new equipment, an existing spray foam rig can be converted for slab lifting.  Here’s all the equipment you need:

• MixMaster Pro Slab Lifting Gun with Ports
• Titan 440 Flush Pump with Hose
• Dial Indicator Stand

Don’t bring a knife to a gunfight! Spray foam insulation guns are made for the simple process of spraying foam at constant pressures. The MixMaster Pro slab lifting gun designed to deal with changing pressures and back pressure without backing up or crossing over. Issues like leaky port connections, constant cleaning, and constant fumbling around with a clamp can drastical­ly reduce production - adding a lot of man hours to each project. Not to mention long nights spent rebuilding and cleaning the gun after EVERY job. Kiss all that goodbye, with a leak-proof gun that handles back pressure and is bulit to last! The Titan 440 is a pre-grout injection water flush pump for flushing Alchemy-Spetec’s MixMaster slab lifting gun. The Dial Indicator Stand provides real-time lift measurement during the concrete slab leveling process.

Alchemy-Spetec is pleased to announce that our VP of Sales and Business Development, Jim Spiegel, recently completed Tier 1 of ICRI's Concrete Repair Technician Program.  As the industry leaders in technical support for contractors, distributors, and engineers, we pride ourselves in a company culture that encourages ongoing technical training for employees and executives. 

More on the ICRI Concrete Repair Technician Certification Program from ICRI website...

This online certification program was developed based on industry demand and...outlines repair inspector qualifications for the inspection of concrete repairs, and designates an individual who has been certified as an ICRI Concrete Surface Repair Technician, as a qualified inspector.

The Concrete Surface Repair Technician Certification Program is a competency-based program using current best practices for online training and evaluation. The Educational component is presented and tested online while the Performance component is tested both online through a knowledge exam and assessed by observable criteria (video submission or live recorded).

Tier 1 only applicants are those who may not be regularly engaged in concrete surface repair inspection and testing, yet have an active interest in learning more about the inspection and tests, be introduced to types of concrete deterioration, understand the requirements for a quality concrete surface repair, be aware of repair materials and methods, and be qualified to perform pre and post-placement inspections and testing.
