Concrete Driveway Sealers Explained!
What kind of concrete sealer do you need? That is pretty much the simple question most homeowners want answered. In an effort to simplify concrete sealers, there are only two groups of concrete sealers to be concerned about; penetrating sealers and topical sealers. These are essentially the same for other types of materials such as stone, brick, and tile sealer. Penetrating sealers are sealers that penetrate the slab from ¼ inch to 4 inches. These sealers are superior to coating sealers in that they penetrate deep into the pores of the concrete. Coating Sealers are less expensive than penetrating sealers. These types of sealers are still very good at helping the concrete to cure evenly. The downside is that, although cheaper, they will require more frequent applications
Penetrating Sealers (chemically reactive)
Silane; must be applied heavily which may darken concrete, life span 5-8years with good saturation, less stain resistant, cost is higher due to heavy application rates
Silicate; applied after 7-14 days; permanently binds with concrete to seal slab and reduces the porosity of the concrete; heavy application required to get protection on the surface, difficult to penetrate smooth floors, difficult to get heavy coat on broom finished slabs, agitate with a brush
Siliconate; can be used as a cure and seal when applied day of the pour, permanently binds with concrete to seal slab by reducing porosity, best water repellent with long life span, large molecular compound for porous finishes. Overall good choice for driveways.
Coating Sealers (film-forming; similar to paint)
Siloxane; very similar to silicone
Silicone; low UV resistant; low lifespan; low abrasion resistant, low chemical reaction making it a film- forming type sealer
Acrylic; life span of 3-6 years, water based, cheaper alternative, two coats recommended, can yellow with age, basically a clear paint
Polyester; twice as thick as acrylics, most polyurethanes are moisture intolerant; which means the surface must be dry when the sealer is applied or else a chemical reaction will occur that results in foaming.
To summarize, the best topical concrete driveway sealer is a Polyester based product with Acrylic based products being next in line. The best penetrating sealer is a Silconate based product. Coating or topical sealers are cheaper but won’t last nearly as long, requiring more frequent applications. Penetrating sealers are more expensive initially but will require fewer applications and protect your concrete driveway for years to come, never requiring a second application.
The ABC of Skyscrapers – Concrete Boom Pumps
Over the years, the world has witnessed some fantastic buildings being erected in an amazingly short span of time. The exploits in the field of engineering has gifted engineers with some fantastic tools to carry out the various tasks related to construction in a relatively easier way.
Every single step needs to be taken carefully when you start constructing a building from the scratch. Perfection in all these steps ensures a strong and healthy structure. From leveling the ground to the final touch up, constructors can find equipments and tools for every single task.
After the leveling and addition of gravel, you need to start with the huge task of pouring concrete. This particular step is a major defining factor when it comes to the strength of a building. Concrete pump trucks have been used to pour concrete for a long time now. Other than concrete pump trucks there are a large number of options that engineers can choose from. However the most popular amongst the various concrete pumps available in the stores is the Concrete Boom Pump.
Effective and User-friendly
Concrete Boom Pumps: These pumps are used in the construction of high-rise buildings. The ability of these pumps to reach distances up to 175 ft makes them the first choice of engineers. Truck mounted concrete boom pumps available in the markets are widely used as they help in pacing up the whole process of pouring concrete.
Having won accolades all over the world, manufacturers also provide customers with various options like different boom configurations, various pump sizes and remote controls. The truck mounted concrete boom pump is a single entity compiling a frame, a pump and a truck. These devices work in unison and help in pouring concrete in a wide area in a short span of time.
The fact that concrete boom pumps have been appreciated by people around the globe stands to the advantage of customers. A large number of brands and companies manufacture these pumps and the competition amongst these manufacturers has forced them to sell these pumps at decent prices.
Other Concrete Pouring Options
Other concrete pouring devices include line pumps, mortar pumps, gunite pumps and mudjacking pumps. These devices have also proved to be very useful but none has proved to be as effective as concrete boom pumps. Similarly you can find skid mounted and rail mounted concrete pumps. However these pumps can only be used mines and tunnels. While concrete boom pumps are used for bigger constructions, other pumps are used for small scale constructions and hence depending on your need, you get a wide range of concrete pumps to choose from.
If you are looking to purchase a concrete boom pump, you can look for various manufacturers over the internet. The internet is a great shop for purchasing absolutely anything you want and often the deals you get over the internet are better than those you would find in stores.
