    Hi
    I have recently had a porch built and now need to look at re landscaping the front of my house which is set over a metre above pavement level some 5-6 metres back.
    Currently it is semi held with a low retaining wall and a real slope of garden. I want to retain at the top to ensure my porch doesn't go anywhere and then build different levels into the sloped garden.
    Will using blocks be ok for the retainer and then use normal bricks to face it with? Tied in of course.
    What would be the best blocks to use and how best laid?
    Will build on a concrete footing etc at 1ft below ground level.
    How best to incorporate drainage into both types of walling?
    Hope you can assist, thanks

    The porch found's should be built so they "don't go anywhere" irrespective of what the adjacent groundwork is doing.

    Hi
    Thanks nosall

    Sure hope it wouldn't go anywhere :)
    Its just that the ground just in front of the porch does drop away quite sharply thus need to extend the pathway on exit anyway hence the need to build the retaining wall.
    Any assistance re the best way to construct the wall much appreciated. Thanks Lisa

    As with any wall, the foundations will be dictated by the ground conditions.

    So, the depth of the foundations will likely be affected by the sloping ground, i.e deep enough to be suitable. Similar with any walls.

    A typical 1m high wall would need say a minimum of 150mm of concrete for the foundations. A retaining wall would prolly need something like 200mm thickness and be at least 150mm wider than the wall each side. The concrete would need to be laid on 'good' ground.
