Understanding soils as they relate to interlocking concrete paver (ICP) installation is vital to a successful project. Identifying soil types and knowing what effect each one can have on project length and labour requirements is also imperative. Further, knowing the soil type …

One of the benefits of interlocking concrete pavers (ICPs) is the relative ease and speed of routine maintenance and minor repairs. For example, in cases where paving units may have settled as a result of rainfall, severe weather, or repeated loads from heavy vehicles, it is a relatively simple procedure to…

Interlocking concrete pavers (ICPs) are typically constructed as ‘flexible’ pavements on a well compacted soil subgrade and compacted aggregate base. Hand-sized concrete paver units are then placed on top of the base on a thin layer of bedding sand. The pavers are then compacted; sand is swept into the joints, and…

Those in the Canadian pool industry know how seasonal climate change can affect an inground pool surface. It is one reason why many pool owners turn to specialists when they are finally able to see what lies beneath their cover when they open their pool in the spring.

Conventional or gravity segmental retaining walls (SRWs), referring to manufactured retaining walls, as opposed to natural stone walls, effectively limit the movement of the soil behind them, primarily by the weight of their blocks. The maximum wall height of a single-depth wall is typically directly proportional to its weight, width, batter (face slope), soil condition, and site geometry. (Contractors should, in all cases, refer to the manufacturer’s instructions for specific recommendations.) The theory behind these retaining walls is to effectively alter the landscape to increase the area of usable land. On occasion they may be used in cases where there is a very steep or rapid change in the site grading. Retaining walls actually have an extensive history dating back to the introduction of primitive agriculture. These early efforts to improve agricultural production often used readily available local materials to alter the existing natural terrain and drainage patterns.
