Why We Use NSF Approved Polyurethanes

GCS March 29, 2020

As mentioned in our previous blog post, The Importance of NSF Approval…

The National Sanitation Foundation develops public health standards and certification programs that help protect the world’s food, water, consumer products and environment.

In a lot of cases, it’s very important to make sure the products a contractor uses on your property meet NSF/ANSI 61-5 standards for contact with drinking water. This testing covers all products that are usually used in or around drinking water from source to tap.

While the polyurethanes we use rarely come into contact with drinking water, this level of safety certification ensures that the cured product poses no threat to the environment.  Once installed, these high strength polyurethanes will be supporting your slab or structure for many years to come.  Make sure the contractor you choose for your project offers NSF approved lifting and soil stabilization material.

It can also be important to have NSF approval on products that don’t come into contact with drinking water, in order to be sure they’re safe for the environment in general.  Having NSF approval on the products your contractor uses can be critical.  When we evaluate a possible repair job on your property, we will take this into account and use NSF approved products when necessary.

Four Advantages of Lifting vs Replacement

GCS March 28, 2020

One of the main alternatives to lifting a sunken slab is tearing out your old concrete and replacing it.  If your slab is still intact for the most part, it can usually be lifted back into place with polyurethane foam.  If you have a choice between concrete leveling and complete replacement, please consider the following points…

No Excavation

Unlike the disruptive process of tearing out and replacing a slab, polyurethane slab lifting does not require excavation.  No one will have to dig up your drive way and get dirt all over your yard.  Instead, a friendly and professional GCS crew will inject the resin through your existing slab using holes half the size of a dime.  The concrete will be leveled and the small holes will be plugged with either a non-shrink cement grout, durable epoxy or a high strength polymer cement.

Clean & Environmentally Friendly

The main lifting foams we use, Alchemy-Spetec’s AP Lift 430 and AP Lift 475, are NSF certified safe for contact with drinking water after they cure.  With that high level of safety certification, you don’t have to worry about the long term environmental impact.  Meanwhile, what happens to torn out concrete?  Very often, it ends up in landfills.

No Heavy Equipment Required

Slab lifting crews are like a small SWAT team: focused, efficient and precise.  There will be no need for heavy equipment on the job, tearing up your yard or making loud noises that disturb your family and/or your neighbors.  Instead, you would have a small truck parked near the slab and a small crew running hoses out of the truck to the slab surface where they are pumping the foam.

No Permitting Required in Most Cases

One last thing to keep in mind: new construction often requires permitting.  Don’t want to spend hours down at your local permitting office dealing with the bureaucracy?  You most likely won’t have to if you just have the slab lifted instead.
