| Garden edges are distinct lines constructed to divide garden beds and lawn, or garden beds and pathways. Functions of garden edges: Prevent lateral movement, Separate different materials, Restrain and support paved areas, Define different uses of areas, Drainage and run-off, Aesthetics. Material considerations: Cost, Availability, Maintenance, Dura... |

| A retaining wall is a structure built to hold back a slope or increase the stability of a slope.
It's purpose it to prevent lateral movement (movement downhill) of an embankment or slope. There are two types: Solid face/pitch, Dry packed. Batter is the angle at which the wall is constructed. Selection of wall: Consider the points when choosin... |

| The angle of repose of a soil is the gradient of the slope at which the soil settles naturally. A firm soil will have a steeper angle of repose than a loose soil. Probable angles of repose (natural): Very wet clay - 150,
Wet clay - 180, Wet sand - 250, Sandy gravel - 26 - 270, Dry earth/dry clay - 300, Damp sand - 33 - 340, Dry sand - 35 - 360.... |

| Steps for laying garden brickwork: 1. Make yourself a simple gauge rod with the correct measurements for the size of brick you are using. 2. Roll out your string line the length of the wall, wrap it around your pegs or bricks which are further apart than the length of wall and pull the line tight. 3. Mark out the corner of the wall, using a square.... |

| Retaining Walls: • define boundary - security, privacy • stabilize slopes - land degradation, erosion • support structures - buildings, table and chairs • containment - soil, water etc • separation - different areas, level changes • increase usable land • aesthetics. Important points: Water must be drained, strong and durable foundat... |

| Failure of retaining walls: 1 breaks 2 slides 3 rotates 4 weak construction - both wall and foundation 5 water not drained behind wall 6 poor materials. Problem solving: Make wall construction stronger - increase material, type of material. Increase foundation size. Slope reinforcement - shear keys, pins, geo-textile. Tie backs... |

| All garden brickwork must be laid on a foundation (footing). The foundation must be strong enough to handle the required load, even and level. Two types of foundation: Strip: Level ground, minimum 150 mm Deep and twice as wide as masonry bearing on it. Stepped Strip: Sloping ground, each step must be exactly the height of one or more bricks plus mo... |

| A garden bridge is a structure built for people to cross areas that are obstacles to travel across e.g. ponds and watercourses, dry creek beds. Bridges must support their own weight plus the weight of people using it. Types: Beam or Girder - Solid girders rest on supports at each end. Cantilever - Two beams are joined together above middle of water... |

| Once the design of your garden renovation is complete the construction can begin. The first thing to do is clear your existing garden of the items you aren’t using in your garden including trees, shrubs, old pavers, ornaments and structures. If you are fairly fit and reasonably competent you may be able to do this yourself and save some money. To... |

| A garden edge is a distinct line which divides garden beds and lawn areas. They are generally easy to construct and save a lot of time and money when it comes to maintaining your garden. Types of Garden Edges: 1 Cut edge
2 Planted or hedged 3 Concrete edging 4 Paver and brick edge
5 Rock edge 6 Timber edge 7 Pipes and tiles 8 Mixed edges.... |
