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.


The cement reacts with water in a process known as concrete hydration. This process hardens the cement over several hours.

Concrete is distinct from mortar. It is composed of aggregates that are bound by bitumen or polymers. It's not a coarse granular material and can be placed in a form of thixotropic. It is used as a filler between masonry pieces or to cover coarse aggregates that have been set.

The cement used in construction is typically non-hydraulic and lime-based. It is either hydraulic, or less often, non-hydraulic depending on whether the cement is able to set when it comes in contact with water.

This allows setting in wet conditions, or even under water. This further protects the hardened material against chemical attack.The chemical process that makes hydraulic cement was discovered by the early Romans who utilized volcanic ash (pozzolana) with added lime (calcium oxide).Non-hydraulic cement (less widely used) isn't able to be set in moist conditions or under water.Rather it sets once it sets and reacts with carbon dioxide in the air.It is invulnerable to attack by chemicals after setting.The term "cement" is traced back to the Ancient Roman term opus caementicium for a masonry resembling modern concrete that was constructed of crushed rock with burned lime to act as a binder.The volcanic ash and pulverized brick supplements which were added to burnt lime, to obtain a hydraulic binder, were later identified as cementum, cimentum, cament as well as cement.In modern times organic polymers may be used as cements for concrete. The world's cement production is approximately 4.4 billion tonnes annually (2021, estimation), of which about half of it is produced in China and the rest is made in India as well as Vietnam.The cement production process accounts for almost 8percent (2018) of global CO2 emissions, which includes heating raw materials within the cement kiln through combustion of fuel and release of CO2 stored within the calcium carbonate (calcination process).Its processed products that are hydrated like concrete gradually resorb CO2 from the atmosphere (carbonation process), compensating for approximately 30% of the initial CO2 emissions.

As a licensed property manager who manages townhomes and condos, I have used United Structural on many occasions to correct structural deficiencies. The projects have varied, some have been extremely serious in nature. I have always been extremely happy with the outcome, and United Structural has become my "go to" . Highly recommend!

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 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.

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

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!
