When it comes to slab-lifting settled concrete this is a more than valid question and it should be asked!!! The traditional method of lifting settled concrete is referred to as “mud’-jacking” which employs hydraulic technology
whereby a low mobility grout is injected at low pressures through a drilled hole and the settled concrete slab is lifted and typically to do a proper job the Mud-Jacking Handbook requires holes to be drilled no farther than 3’ apart. The Poly-Mor technique of lifting settled concrete slabs utilizes a chemical lift whereby two liquid components are mixed and injected through a small hole and the foaming action of the two components lifts the settled concrete slab with ease. The following diagram shows the advantages and disadvantages of grout over foam:
Another valid question to ask once you are convinced that the superior technology is the use of a light weight foam product is “How Long Have You Been In Business?” We suggest this question because lifting using an expanding polymer resin, if not undertaken by seasoned technicians can result in shoddy workmanship and
Poly-Mor has experienced the “learning-curve” as we have been in business for just about 20 years. Our promise to you is “If we do not do what we say we can and will do, we will not charge you!”
From Mr. & Mrs. Rentsch – “Jarrod and Mike just finished up and did a fabulous, professional job and they were courteous and friendly. Please convey our sincere thanks to them.” I will be certain to spread the good word about Poly-Mor. It was a pleasure dealing with you all.”
The Power of polymers
As we explained in a previous Poly-Blog, the formulation of polyurethane comprised the mixing of a polyol and an isocyanate that has to be mixed at the downstream end of the process. In the mixing and subsequent expansion of the two mixed components the chemical reaction that takes place produces an exothermic reaction – ie: the reaction itself produces heat or a thermic reaction. The amount of heat produced is approximately 2750 F. It is important to understand this phenomenon as if polyurethane is used around plastics pipes made of polyethylene or polypropylene where the melting temperatures are less than the heat created by the exothermic reaction of the polymer formulation then the possibility that the pipes could melt would be a reality. It is noted that those experienced in the use and application of polyurethane systems would not be challenged with a scenario where plastic pipes were involved.
R-Value Water Line Insulation
Polyurethane foam is an excellent insulating material. In fact more and more developers are going to polyurethane foam systems to insulate residences and commercial buildings because of the thermal characteristics of polyurethane and the fact that it is applied in situ and provides a vapour barrier as well as a thermal barrier all-in-one. Closed cell polyurethane systems provide superior thermal characteristics. The polyurethane systems used by Poly-Mor for slab-lifting, void-filling and leak sealing have a R-value of some
R-5.5 – R-6.0 per inch of thickness.
I would like to thank you, and your team for a job will done on my concrete pool deck slab lifting at “222 Carson drive, Hamilton, Ontario” . They did an amazing job on my concrete slab lifting. Again, thanks for very good work, and I am sure we will be dealing with your company with lots of work ahead in the near future.
Having briefly covered the fundamentals of polyurethane foam systems we will get into the products Poly-Mor Canada Inc. specializes in and thereafter we will get into the applications under each of Poly-Mor’s unique products.
The Power of polymers
When describing any specific polyurethane system whether it is used for slab-lifting, void-filling, leak-sealing, etc. the system is typically referenced in terms of its density. For example, for slab-lifting, the foam system Poly-Mor uses is a 2 ½ lb. expanding polymer density system. What does this mean? The meaning of density is simply that it takes 2 ½ lbs. of liquid material which will expand into 1 cubic foot of solid polyurethane material. Similarly, if you had a 3 lb. polyurethane system it would take 3 lbs. of liquid material to give you 1 cubic foot of solid material.
Closed Cell Content
It is noted that in order to maximize the closed cell content of any foam system it must have a minimum density of 2 lbs. or more. The low density foams typically used for insulation purposes is well below the 2 lb. density requirement for closed cell material. The polyurethane foam you can purchase at a hardware store is very low density and hence open celled material which will nor stand up to exterior environmental conditions, especially freeze/thaw cycling.
There is a direct relationship between the density of the foam system and its engineering or structural characteristics such as compressive strength, elongation strength, flexural strength and tensile strength. The adjacent chart demonstrates this relationship and the impact of density upon compressive strength. The other relationships can be viewed on our web site at www.Poly-Mor.ca
I would like to take this opportunity to express my thanks and pleasure with the slab treatment Poly-Mor recently completed at my home. I want to express what a pleasure it has been to deal with Uretek. Right from the first contact with Harry, through dealing with the crew at my home, to receiving the bill. You should be proud and comforted to know that such a top-notch bunch of guys represent your company. Next Time
Next time we will briefly review other characteristics of polyurethane foam like exothermic reaction, R-Value, etc.
Over the next number of months, together we will be reviewing the basis of our technology, the products offered by Poly-Mor Canada Inc. in meeting challenges related to slab-lifting, soils stabilization, leak sealing and other applications, as well as advantages of our technology over other technologies like mud jacking, pressure grouting etc.
Everything Poly-Mor does and every product application is based upon the use of a specific expanding polymer system. Depending upon the product application, engineering specification, desired results, etc. an expanding polymer resin system will be employed. In more simplified terms the expanding polymer resin systems are different polyurethane (PU) systems. Polyurethane is a two part chemical system where a Polyol and an Isocyanate are mixed at the end of a specialized injection gun. The Polyol and Isocyanate start to gel within seconds and expand up to 20 times their liquid volume. The below video demonstrates this process.
I would like to thank you and your team for a job will done on my concrete pool deck slab lifting her in Hamilton, Ontario” , they did an amazing job on my concrete slab lifting. I only hired them to do one part of my concrete slab fixing but I will be doing the rest to complete the fixing of all slabs around my house in near future.
I also, will be recommending your company to all our offices of Stantec Consulting for any future jobs requires your expertise. This solution of concrete fixing for slabs and foundation will be a great money saving to lots of our clients and adding to this type of product used as environmentally friendly product and very efficient way of permanent solution.
Again, thanks for very good work, and I am sure we will be dealing with your company with lots of work ahead in the near future.
We will address certain terminology relating to polyurethanes such as density, exothermicity, R-Value, etc.
The Power of polymers
Poly-Mor Canada was inaugurated in 1998 as an alternative technology to mud-jacking. Initially incorporated as Foam-Tek Canada Inc, and shortly thereafter the name was changed to Poly-Mor Canada Inc. In 2008 we rebranded ourselves as Poly-Mor Canada Inc. We are proud to note that we were the first company in Canada to use expanding polymer resins systems to lift and stabilize sunken concrete structures.
Our Company’s objective is simple. POLY-MOR will provide quality concrete slab-jacking, stabilization, leak sealing and restoration services to customers at fair prices. The price of our services will reflect work safety, quality materials, efficient work, and profit margins that provide long-term company growth and stability.
Since or inception in 1998 we have expanding our slab-jacking technology to a point where we are now a national company with offices from Vancouver to Halifax. During this period of time we have undertaken literally thousands of slab-jacking jobs from the smallest or residential jobs to slab-lifting of bridge approaches and concrete paved roads.
I just wanted to thank you and your crew for the very prompt service work on our patio today, it looks great! Couldn’t tell anyone was even there. Will recommend Poly-Mor to anyone down the road that needs work done. Dave
Stay tuned! Our weekly Poly-Blog will be communicated starting next week on what our focus will be over the next number of months.
