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.
Renovation can turn into a nightmare if your builders or subcontractors fail to do a good job. Always be suspicious of an estimate or quote that is considerably cheaper than all the others, or someone who is available for work immediately. Ask for references, and speak to their previous clients. The golden rule when refurbishing older buildings with solid walls is to use traditional materials that are compatible with the way they were originally built, i.e. lime-based mortars, renders and plasters, rather than anything containing modern cement. Old buildings with shallow foundations are affected by seasonal ground movement and because cement is very brittle it tends to develop small cracks. This allows rain to penetrate, which then can’t escape. Modern paints applied to walls can also cause trouble by blocking natural evaporation.
Accidents involving construction vehicles, such as dump trucks or backhoe loaders, are a common hazard of trenching sites. Mobile equipment operators might have an obstructed view and therefore not be able to detect when they are approaching the perimeter of the trench. OSHA suggests that a spotter or a flagger be designated to direct the mobile equipment operator and prevent the vehicle from falling in the trench. When material is being loaded or unloaded from the construction vehicle, workers should be required to stand back in order to prevent being hit by flying debris.

These pros like soapstone because the lines created by grease pencils and markers can stay visible for a long time, whereas soapstone washes off in the rain. The downside is that soapstone doesn’t work as well on wet blocks. You can find these pencils at online retailers. Stagger the overlaps (at least 4 inches for this Versa-Lok product) and try to keep the butt joint between the blocks as tight as possible. Large gaps can create a pathway for water and sediment. Whichever type of block you use, make sure you follow the manufacturer’s instructions.After your drainpipe is in place, you should backfill the rest of the space behind the blocks with either sand or pea gravel—either will allow water to filter through to the drainpipe at the base of the wall. For the best results, backfill with a few inches of the material after laying each course of blocks, and use a hand tamper to compact the material. By tamping the backfill every six inches or so, you’ll ensure that it is packed tightly, which will provide additional support from the pressure of the soil behind the wall.
By using NFC you are basically increasing the depth of your retaining wall. Most masonry blocks would be an average depth of 200-250mm, by using NFC you are increasing that depth of your solid masonry block from 200mm up to 500mm (Infill depth) or more depending on the height of your wall. It is always recommended that every third or fourth block should have part of the back edge removed. This would give a far better adhesion tying the NFC infill layer and the NFC core filled blocks creating a far stronger structure. Find more info on here.
