In addition to causing expensive damage to municipal infrastructure, hitting utility lines when digging can also cause electrocution and natural gas leaks,which can lead to worker fatalities. Fortunately, you can easily avoid hitting utility lines by contacting your local utility companies before you dig. Simply call your local 811 agency and allow the required time for the utility companies to mark their lines. Not only will this keep your crew safe, but this will help to prevent your company from being fined since digging without calling is illegal in many states.
Most materials come in standard pack sizes, so quantities of things like insulation, bricks and blocks need to be rounded up. Contractors know that an allowance needs to be made for breakage, both in delivery and on site. Reclaimed materials for renovation projects have an even higher wastage factor. You may need to over-order by up to 20 per cent on second-hand bricks, slates and tiles compared to around five per cent for new. Better order too much than not enough. Any surplus can usually be sold or returned. Renovation work always costs more than you expect. This is because some problems are not revealed until you start work and uncover them, but mostly because items are forgotten from the budget, or because you change your mind and alter the design or specification.
Trenched areas sometimes have depleted oxygen levels, which is safety hazard that must be taken into consideration on excavation sites. The atmosphere in trenched areas can also be contaminated by toxic gases and chemicals. For these reasons, OSHA requires atmospheric testing to be performed by a qualified professional in excavations that exceed four feet. If atmospheric hazards are present, then workers must wear the appropriate respiratory protection equipment depending on the hazard in the excavated area.

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 lay blocks on an unlevel surface. The first course (or row of blocks) sets the stage for the rest of the wall, so it’s vital that you make it perfectly level. If it isn’t, subsequent rows won’t be level either, resulting in a retaining wall that’s lopsided and unattractive. Use a four-foot carpenter’s level to ensure that the gravel layer below the first course of blocks is level before you start setting the blocks. Any discrepancies here will show up higher in the wall. DO stack blocks at a slight backward slope.
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. Discover extra information on https://stormheart.net/.
