Gravel is just one of those things where we know it when we see it. If someone asked us just what gravel is, we might have a hard time expressing it, but we know we see it almost daily. Gravel is everywhere, and used in everything. But gravel doesn't come from just any old rocks; it has to come from a certain kind of gravel rock deposit and meet other qualifications to be considered gravel.So what kind of rock is used to make gravel, and how do they effect the gravel that is used in common [...]
Concrete acid stain can be applied to new or old, plain or colored concrete surfaces. They are available in 10 basic colors. Although they are often called acid stains, acid is not the ingredient that colors the concrete. Metallic salts in an acidic, water based solution react with the concrete to permanently color of the surface. Siliceous aggregates such as gravel or sand, do not react with the stain. Surfaces containing a higher content of cement will react more than one with less cement [...]
Stone cobbles are one of the most beautiful materials to use in paving. Done properly they have a European elegance and robustness which is hard to match.Cobbles come in several types of material, including granite, porphyry and even concrete. They can be laid on a sand base if they are at least 60mm thick and grouted with gravel, sand, tar or mortar. For the best results though they should be glued onto a concrete slab and this article discusses this procedure.Cobbles can be purchased either as[...]
You're probably planning a Shotcrete or Gunite pond, but I bet you do not know what Shotcrete and Gunite are. Come on. Take a guess. If you answered, a sprayed concrete, that would be incorrect. In reality, Shotcrete is an all-inclusive term used for describing the process of spraying concrete or mortar through either a wet or dry application technique.Gunite, on the other hand refers only to the dry-mix process in which the dry cementitious mixture is blown through a hose to the nozzle, [...]
Catchpits refer to a pit inside a drainage system. This piece in the drainage system collects matter that could potentially cause blockage. On draining systems that do not make use of any sort of geo-membrane, a catchpit system is appropriate. This will minimize the collection of soil particles and other pieces of sediment like grits and silts. This pit must be considered before setting up outfall.When you look at a catchpits piece, you will see an empty chamber. It will also have an inlet pipe [...]

There are many different varieties of concrete blocks. But, the majority of building blocks are simple rectangular blocks of cement, which are gray or white concrete. The average concrete block measures 1ft 6in x 9in and can range in thickness from 3 inches to 9 inches. There are special instances where this thickness may differ a classic example of this would be a foundation block which although maybe thicker if required will still measure about the same.There is another terms you may come [...]
Two frequent questions I get from homeowners: My driveway sounds hollow... is that bad? Sand runs out the end of my drive after it rains... is that bad? If you have significant voids or space between the concrete and sub grade or if your drive is on a steep grade, this can certainly be "bad". Does your drive make a thumping noise when you drive in on it? Maybe it rocks when you drive over it. Can you see between the joints? Are there visible cracks? Does it look like your driveway concrete is[...]
