Many renovators also have a tendency to underestimate the level of work required to upgrade existing services such as electrics and heating systems to make them fit for purpose. A lot of unnecessary work can be prevented in period properties (1930s and older) by adopting a ‘repair not replace’ approach. Overhauling original doors and windows and retaining period features is often cheaper than replacement, adding value in the process by enhancing period character. In many cases, the original door and window timbers and joinery were of far better quality than today’s equivalents. Fitting secondary glazing to original windows is often a good ‘best of both worlds’ solution. If modern double-glazed units have misted, you can save a lot of work by replacing just the glazing panels, rather than the whole window. With roofs, localised repair may be all that’s needed in most cases. Surveyors can sometimes pass premature death sentences when there may be another 10 or 20 years’ lifespan left.

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.

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.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.

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. Find additional details on this website.
