Precast Concrete Retaining Walls

Precast retaining walls are now widely used across a variety of industries, most notably construction and agriculture. Ease of construction and durability are the products two main benefits.

Precast concrete products in general have some obvious benefits over pouring concrete on site. The ability to make something in a factory controlled environment makes it so much easier to produce a good quality product with the right type of finish. This means products can then be delivered to site and installed with minimal hassle.

Concrete retaining walls are used across a variety of areas, one of the most common uses is creating storage bays for aggregates and similar products. Once a flat base has been created, the product can then be installed in a number of ways. The type of product used will depend on what needs to be achieved, the standard product tends to be an L shaped retaining wall unit. This is more often than not bolted down to a concrete slab. The slab itself needs to be approximately 200mm thick or more. The units are then put into place, and then a drill is used to drill out the fixing points. Once this is complete, the holes need to be blown out, and then resin is placed in, and threaded bolts are placed into the resin and then it is all left to go off. The final stage is then tightening the nuts onto the threaded bars.

One potential issue which can arise from this method of installation is that the foot of the units is a potential hazard to machinery or diggers. It also means that the fixing points are left exposed to potentially corrosive materials. If either of these things is an issue, then the other method of installation is to cast in the retaining walls units into the floor slab. This means the units will be tied into the floor slab, and avoid the problems discussed earlier.

The nature of precast concrete means that the units should last for a long time, depending on how careful people are when using them. Obviously diggers can make a large dent in concrete if people are not careful! Barring heavy handed machine drivers, the units will last a very long time.
