Dirt Removal services in Fort Collins, Colorado? 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.
When renovating a property it can sometimes be tempting to give heavily advertised ‘miracle cure’ treatments a try, lured by extraordinary claims such as ‘never paint again’, ‘seal leaks for good — instantly’ or ‘the ultimate solution to all roofing problems’. But some of these products can actually be very damaging when applied to older buildings. Spray-on renders and polyurethane foams can block crucial ventilation paths in walls and roofs, and despite claims to the contrary offer virtually zero insulation benefits. Instant damp sealants are rarely effective and can trap damp in walls. Basically, if something sounds too good to be true, it probably is.
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.

If the wall runs up a hill, continue each base course into the hill until the top of the second course is level with the grade, and then start your second base course at that point. If you have the option, it can be easier to excavate and lay the lowest course before excavating the trench for the next step, especially if you have to step up several times. Save yourself some money and install the cheapest style/color that matches the wall style (usually the gray ones) on the bottom course since it won’t be seen.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.
Ensure you order everything you need at once and set aside an allowance for breakages and cutting. Contrary to popular belief, building a fence on top or behind a Block Retaining wall is rather easy. In some cases where only a small amount of retaining is required as in 200-400mm, the fence can be built directly on top of the wall with the fence posts passing through the walling blocks and concreted into the ground as normal. This method would be ok to use with all forms of fencing such as post and rail, colour bond post and rail, good neighbour fencing, tubular panel and even pool fencing.
