Professional renovators always leave a contingency of between 10-20% to cover these costs and fully expect to have to spend it. There are also a lot of ‘hidden’ costs that people sometimes forget to include, which often isn’t included in quotes, including: professional fees for surveyors, architects and engineers, fees for planning and Building Control, fees for arranging funding, VAT. A lot of homeowners only discover halfway through the works that their plans are completely unachievable on their budget. So it’s essential to research prices in advance.

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.

Get the first course right. Use a torpedo level to level each block front to back and either a 4-foot or 6-foot level to keep each course level and even. Set the blocks with a heavy rubber or plastic mallet. Getting the first course flat and level is extremely important, so take your time. Try to lay the course as close to the center of the trench as possible. Even a small pebble on the surface of a block will throw the one above it out of alignment. And that crooked block will affect the one above it, and so on. That little stone could eventually create an unattractive hump in the top course.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.

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.
