Dirt Removal services in Windsor, Colorado? 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.

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.

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.

Retaining wall drainage is an incredibly important part of building a stone wall. Once a few rows have been stacked, backfill the wall with rock so it matches the grade height in front of the wall, and then lay down perforated drain tile on top of the rock. Install drain tee fittings and a drain grate every 25 feet to 50 feet, depending on how much rainwater is expected to run down to the wall. Cut one block down to accommodate the drain grate. Screw the drain tile parts together so they won’t come apart when they get covered with more rock. Also, drain the tile to daylight at the ends of the walls whenever possible.A wall that leans into the soil it retains is less likely to be pushed outward by soil pressure than a plain-old vertical wall. Design and build your retaining wall to slope at a minimum rate of one inch for every one-foot of rise (height). Fortunately, working with retaining wall blocks makes it incredibly easy to achieve this “step-back” construction! The locking flange on the bottom edge of every block guides it to click into position slightly behind the lower block, preventing the top blocks from being pushed outward.

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.
