SPRAY POLYURETHANE FOAM (SPF)
TOPCOR Services, Inc. has installed several Spray Polyurethane Foam and Coating Applications for a variety of client needs. We use specialized plural component heated equipment to apply the Spray Polyurethane Foam and have installed Spray Polyurethane Foam systems in the following applications:
Spray Polyurethane Foam Applications
Sphere Tanks
Urethane foam is far superior to manufactured sheet goods as an industrial insulation material because it is seamless. Heat loss through seams and fasteners is eliminated.
Advantages of Spray Polyurethane Foam:
- Seamless layer insulation
- Conforms to surface to which it is applied
-Spray Polyurethane Foam physical properties are outstanding compared to conventional insulation systems enabling this product to be used in difficult environments with ease. TOPCOR can offer assistance with complicated processes that require high adhesion values with superior compressive and tensile strengths.
-Spray Polyurethane Foam can be the best choice for your application. Contact TOPCOR Services technical department to discuss potential solutions of using spray polyurethane foam for your application.
TANK CHIME SEALS
If you have tanks at your site, you need to be aware of the potential for damage caused by not having your tank chime properly sealed to the foundation. Having the proper seal for your tank chime can save you from expensive repairs, environmental nightmares and costly down time. The most common reason for tank bottom failure is moisture and/or chemicals trapped between the foundation and steel tank bottom. TOPCOR offers a variety of solutions for your tank chime seals.
Because of the difference in expansion rates of the tank and foundation, the best solution is a flexible sealant for your tank chime seal.
From diagnosis to completion TOPCOR has the personnel, expertise and equipment to handle all of your tank chime seal needs. Our dedication to safety, quality and performance, makes TOPCOR the right choice for your tank chime seal needs.
TOPCOR offers a variety of solutions for your tank chime seal needs:
To protect your investment and safeguard the environment let TOPCOR be the solution for your tank chime seals.
TOPCOR has a history of a good working relationship with manufacturers and suppliers of tank chime seal materials and are certified by many of the leading manufacturers to install their tank chime seal products.
TOPCOR has the staff and ability to meet the most stringent specifications and work with our clients to meet their schedules in order to eliminate downtime.
URETHANE CRACK INJECTION
TOPCOR Services, Inc. has a history of solving our client’s most complex leaks in various concrete structures using POLYURETHANE CHEMICAL GROUTS. We are certified with several manufacturer’s products and can offer a variety of repair procedures specifically designed around the situation.
URETHANE CRACK INJECTION is utilized to prevent water leakage or to stop an actively leaking crack using a polyurethane chemical grout.
If there is concern about material leaking out the back of a crack, polyurethane foams can be used. These flexible to semi-flexible, fast-setting foams are effective alternatives for applications involving only crack sealing (waterproofing) and not structural repair. Because of their flexible nature, they are able to accommodate slight concrete movement so the seal stays intact. They also begin to harden and foam within minutes of injection. This reduces the chances of the material flowing out of an injected crack while still in liquid form, and even if some does leak out, the foam will fill the void.
SPECIALTIES:
Materials:
For Urethane Crack Injection, most of the polyurethane chemical grouts used are single component (water activated) or two component (resin/catalyst). These grouts can have two distinctly different properties, either being hydrophobic or hydrophilic. Hydrophobic grout will repel water (push it away), has high expansion, and cures rigid. Hydrophilic grout will absorb the water that it finds in the soil or concrete, has lower expansion, and cures to a flexible foam. Both grout types are water activated for use in wet environments. These polyurethanes will vary in viscosity and can be accelerated depending on temperature and amount of catalyst used.
Equipment and Application:
TOPCOR uses high pressure, positive displacement grout pumps, hand pumps, and multi ratio devices. Mechanical packers are used for injection pressures between 300-3,000 psi. Depending on the location and environment, TOPCOR has access to various sizes and lengths of mechanical packers. Urethane Crack Injection is usually performed in a wet environment, thus requiring a means for injecting the resin through mechanical injection packers.
