If you're involved with any type of major construction project, you know that you have to cater for drainage and must focus on storm water run-off and management. For this reason, it's likely that you will have to have a specific pit or two installed in order to cope with those all too frequent climatological occurrences in Australia. As you're getting ready to order your storm water pits, how do you prepare for their placement?
Selecting the Design
These structures can come custom-made or according to a modular design. A range of sizes are available and they come preconfigured to accept a variety of different pipes from various angles. You will need to consult with your local authority to ensure that you are installing the right type of product for your surface area and according to specification.
Preparing the Site
Make sure that you construct a well compacted and stable foundation to avoid subsidence as much as possible. You may need to measure with special instruments to ensure that the embedded side is capable of bearing the total weight of the structure above.
Once the foundation has been installed and is found to be suitable, sand or gravel should be put on top to a uniform depth. The level required will depend on the underlying foundation, whether it is rock-based or largely earth.
When the unit arrives from the manufacturer it will typically come with lifting anchors so that it can be safely handled and moved. Note that these pits should only be moved using the specific anchors with clutches or the concrete may crack. If the pit needs to be stored in between delivery and installation, it should only be placed on a specially prepared base, resting on timbers.
Having a Downstream Pipe
When the item is installed, take time to ensure that the downstream pipe is properly situated and secure. This may call for the pipe to be raised slightly before the base of the pipe touches the underlying bed so that it can function correctly. You will need to check the level of the downstream pipe carefully to make sure that it is in accordance with design specifications.
Preparing the Pipe
When removing "knockout" sections from the wall of modular pits to accept other piping, be careful not to cause damage to the adjacent area. Knock the concrete away once it has been initially broken, working from the centre in small semicircles.

Hello, my name is Eric and this is my concrete blog. I am not a concrete contractor but I have recently learnt quite a lot about concrete and concrete pumping. I decided to lay a new concrete drive at my home. The drive is very long and very wide so I needed a lot of concrete. I didn't fancy carrying all this concrete so I opted for a concrete pump. I wasn't exactly sure how to operate this piece of equipment so I contacted a contractor who came out and assisted me. I learnt so much from this guy that I decided to start this blog.
