Sealant is a substance used to block the passage of fluids through openings in materials, a type of mechanical seal.In building construction sealant is sometimes synonymous with caulk (especially if acrylic latex or polyurethane based) and also serve the purposes of blocking dust, sound and heat transmission.Sealants may be weak or strong, flexible or rigid, permanent or temporary.Sealants are not adhesives but some have adhesive qualities and are called adhesive-sealants or structural sealants.


Concrete is a compound material made up of aggregates bonded by a liquid cement that is cured into a solid in time.Concrete is the second-most-used substance worldwide, after water, and is also the most commonly used construction material.Its usage worldwide, ton-for-ton, is double that of steel wooden, plastics and aluminium combined.When aggregate is combined with dry Portland cement and water, the resultant mixture is a fluid slurry which can be easily poured and then formed into shape.The cement is able to react with water in a process known as concrete hydration, which hardens it over several hours to form the hard matrix which binds the materials together into an extremely durable stone-like substance with a myriad of uses.This time frame allows concrete to not only be formed into forms, but also to have a variety of tooled processes performed.The process of hydration is exothermic, meaning that the temperature is a key factor in the amount of time it takes for concrete to be set.

Concrete is different from mortar. It is made up of aggregates that are bound by polymers or bitumen. It's not a coarse aggregate, and can be placed in a form of thixotropic. It is used to fill in gaps between masonry elements or to cover coarse aggregates that have been laid.

A cement is a binder chemical substance that is used for construction that sets, hardens and binds with other materials in order to bond them together.Cement is not often used as its own, but rather as a binding agent for sand and (aggregate) together.Cement in combination with fine aggregate makes mortar that is used for building, or in combination with gravel and sand creates concrete.Concrete is the most extensively utilized material and is a distant second to water as the most consumed resource.Cements used for construction are typically organic, and are usually limeor calcium silicate based and are either hydraulic or less often non-hydraulic based on the ability of the cement to be set when surrounded by water (see non-hydraulic and hydraulic lime plaster).Hydraulic cements (e.g., Portland cement) form and are made adhesive through a chemical reaction between dry materials and water.The chemical reaction causes mineral hydrates that aren't extremely water-soluble.

This permits setting in wet conditions or under water and additionally protects the hardened product from chemical attack.The chemical process used to make hydraulic cement was discovered by the ancient Romans who made use of volcanic Ash (pozzolana) with added lime (calcium oxide).Non-hydraulic cement (less commonly used) does not set in wet conditions or beneath water.Rather it sets after it cools and reacts to carbon dioxide that is present in the air.It is invulnerable to attack by chemicals after setting.The word "cement" is traced back to the Ancient Roman term opus caementicium for a the masonry that resembles modern concrete. It was made from crushed rock using burned lime to act as a binder.The volcanic ash and pulverized brick supplements which were added to burning lime, in order to produce an hydraulic binder, were later called cementum, cimentum, cament and cement.In contemporary times organic polymers are often utilized as cements in concrete. The process of producing cement accounts for nearly 8 percent of all global CO2 emission in the year 2018. This includes the process of heating raw materials with the burning of fuel in a furnace as well as the release of CO2 stored from calcium carbonate.

It was a pleasure to work with Rick and his crew. From the beginning, Rick listened to my concerns and what I wished to accomplish. Out of the 6 contractors that quoted the project, Rick seemed the MOST willing to accommodate my wishes. His pricing was definitely more than fair as well. I had 10 push piers installed to stabilize and lift an addition of my house. The project commenced at the date that Rick had disclosed initially and it was completed within the same time period expected (based on Rick's original assessment). The crew was well informed, courteous, and hard working. They were not loud (even while equipment was being utilized) and were well spoken. My neighbors were very impressed on how polite they were when they entered / exited my property (saying hello or good morning each day when they crossed paths). You can tell they care about the customer concerns. They ensured that the property would be put back as clean as possible by placing MANY sheets of plywood down prior to excavating. They compacted the dirt back in the holes extremely well to avoid large stock piles of soils. All the while, the main office was calling me to discuss updates and expectations of completion. They provided waivers of lien, certificates of insurance, properly acquired permits, and JULIE locates. From a construction background, I can tell you that I did not see any flaws in the way they operated and this an extremely professional company. The pictures attached show the push piers added to the foundation (pictures 1, 2 & 3), the amount of excavation (picture 4), and the restoration after dirt was placed back in the pits and compacted (pictures 5, 6 & 7). Please notice that they also sealed two large cracks and steel plated these cracks from expanding further (which you can see under my sliding glass door). I, as well as my wife, are extremely happy that we chose United Structural Systems for our contractor. I would happily tell any of my friends and family to use this contractor should the opportunity arise!

USS was excellent. They are honest, straightforward, trustworthy, and conscientious. They thoughtfully removed the flowers and flower bulbs to dig where they needed in the yard, replanted said flowers and spread the extra dirt to fill in an area of the yard. We've had other services from different companies and our yard was really a mess after. They kept the job site meticulously clean. The crew was on time and friendly. I'd recommend them any day! Thanks to Jessie and crew.

The staff was helpful, very nice and easy to work with and completed the work timely and cleaned up well. Communications faltered a bit at times and there was an email communications glitch which was no fault of anyone, but no big deal and all ended up fine. We sure feel better to have this done and hope that is the end of our structural issues. It does seem like (after talking to several related companies), that it would be great if some of these related companies had a structural engineer on staff vs using on the job expertise gained over years - which is definitely valuable! But leaves a bit of uncertainty - and probably saves money for both sides may be the trade-off? So far, so good though! Thank you.

USS did an amazing job on my underpinning on my house, they were also very courteous to the proximity of my property line next to my neighbor. They kept things in order with all the dirt/mud they had to excavate. They were done exactly in the timeframe they indicated, and the contract was very details oriented with drawings of what would be done. Only thing that would have been nice, is they left my concrete a little muddy with boot prints but again, all-in-all a great job
