Concrete services in Windsor with Stormheart Construction? Collapsing should be avoided by supporting the sides by either battering them or supporting them with sheets. Materials from the excavation should be stored at a safe distance from the excavation, this will help reduce the risk of them falling onto people. Adding barriers to excavation is an essential precaution to avoid people falling into the excavation. It is safer if vehicles are kept completely out of the excavation area but if required the use of barriers and stop-blocks should help mitigate that danger.
There’s a certain amount of paranoia among the public when it comes to dealing with builders. The fact is, most builders try to do a decent job, often despite late payment and awkward clients giving them a lot of grief. Individual tradespeople can actually be a mine of valuable experience. Of course, sometimes there’s an ulterior motive to drum up business. But it’s often the case that the person tasked with doing the job will know a better, less expensive or simpler solution in a specific area than designers focused on the bigger picture. Trades also tend to have a useful knowledge of materials and local suppliers, potentially helping you save time and money. So don’t automatically disregard advice from the person doing the job.
OSHA defines excavating as “any man-made cut, cavity, trench, or depression in an earth surface formed by earth removal.” A trench is a type of narrow excavation in which the depth is typically greater than the width, which does not exceed 15 feet. According to this definition, all trenches are excavations, but not all excavations are trenches. The specific safety requirements for trenches depend on the depth of the trench.

Get the first course right. Use a torpedo level to level each block front to back and either a 4-foot or 6-foot level to keep each course level and even. Set the blocks with a heavy rubber or plastic mallet. Getting the first course flat and level is extremely important, so take your time. Try to lay the course as close to the center of the trench as possible. Even a small pebble on the surface of a block will throw the one above it out of alignment. And that crooked block will affect the one above it, and so on. That little stone could eventually create an unattractive hump in the top course.DON’T forget to allow for drainage. Groundwater is the natural enemy of retaining walls. When it saturates clay-type soils, they swell and put excessive pressure on the backside of the wall. To avoid failure, make drainage provisions at the same time as you go about building the retaining wall. Backfilling the space behind the blocks with crushed stone and then installing a flexible perforated drainpipe (available at The Home Depot), also called “drain tile,” at the base of the wall could create the necessary escape route for groundwater. The perforated pipe will carry groundwater to each end of the wall where it can drain harmlessly away. The ends of the drainpipe should then exit on each end of the wall, and you may cover them with crushed stone to camouflage their appearance.
If the block Retaining wall is more substantial as in a metre high or more then the fence would have to be behind the wall instead of through or on top. Most Segmental Retaining Wall blocks do not have a big enough cavity or void for the fence post to be directly concreted inside them and would lack the strength to hold the weight of a fence. Generally, most walls are built using an aggregate (Gravel) backfill or in some circumstances No Fines Concrete (NFC). Because of this, an allowance has to be made for the fence post at the early construction stage such as installing PVC Piping as a sleave for the fence post to fit into, this would require some forethought and good planning.
