Dirt Removal services in Windsor by Stormheart Construction? Excavation safety is a combination of safety precautions and mitigations in and around excavations and trenches to eliminate or control hazards in compliance with industry standards and regulations. Why is Excavation and Trench Safety Important? Excavation and trenching are amongst the most dangerous operations in the construction industry. Dangers can include cave-ins, falling loads, hazardous atmospheres and hazards from using heavy equipment. Regular pre-work inspections can reduce hazards and serious risk of injury. Safety inspections should check for the type of excavation being conducted, support and warning systems in place, access areas, weather conditions, heavy equipment and PPE.
Aspiring renovators sometimes get so focused on getting the desired ‘visual result’ with fabulous kitchens, decor and so on, that they risk running out of money for works to the building envelope — sometimes referred to as the ‘unseens’. If you don’t prioritise key works, such as leaking roofs, timber decay and structural movement, it won’t be long before deterioration of the fabric takes hold, at which point it might be a matter of some regret that so much of the budget was showered on top-of-the-range designer appliances.
Trenches 5 feet to 19 feet: OSHA explains that any trench other than those made of stable rock exceeding 5 feet in depth must have a protective system in place. The protective system must be implemented by a competent person. This can be any worker who is qualified and capable of identifying rock and soil composition and hazardous excavating conditions in addition to possessing the knowledge and authority to take corrective action.

Which retaining wall blocks are best? These solid blocks are heavy. Lighter, hollow blocks are available, but they can’t be split because cutting them will expose the voids. Also, some hollow blocks require individual backfilling, which is time consuming. These pros prefer Versa-Lok blocks, which are held together with pins rather than a lip on the bottom because pinned blocks work better on tighter curves, and the flat bottom makes them easier to stack. They have also found that the small back lip on some lipped blocks can be prone to cracking, which will weaken the wall.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.
NFC can either be mixed on-site for smaller areas or purchased from a reputable concrete supplier and trucked in for larger commercial applications. NFC is mixed at a 6:1 ratio by volume of 20mm max size clean aggregate and cement. Water content should be such that the cement slurry evenly coats the aggregate and retains a wet/glossy appearance without excess slurry running off, this is typically around 40 litres per 100kg of cement. With the use of NFC, we are able to build Block Retaining Walls in areas and situations where normal construction methods would not work. Some of these situations are: In areas where excavation behind the wall is limited either due to being on a boundary or close to other structures or footings. Find extra information on here.
