Earthworks, external works and drainage in Kuching

Yes. The land is cleared, levelled and compacted, a membrane is laid and crusher run is spread and rolled. It is quick, drains well and can be built on later. We will say at the site visit whether the ground needs anything more than that.

Usually the external apron. If it has settled so it falls back towards the house, rain runs to the base of the wall and rises through it. Re-laying the apron to fall away, with a drain at the low point, fixes the cause; repainting the inside only hides it until the next monsoon.

Often yes: cutting in a linear channel along the low edge and connecting it to the existing sump. Whether that is enough depends on where the water is currently going, which is a site visit question.

The slab has no fall, or it has settled so the fall now runs the wrong way. Kuching gets over four metres of rain a year, so a porch that is a few millimetres out over its length holds water every storm. The fix is to re-lay the apron to a set fall with a channel at the low point; grinding or topping the existing slab only moves the puddle.

Usually yes for a retaining wall above a certain height, and for anything that changes where water leaves your lot. Those are the two things a local authority checks, because both end up as the neighbour’s problem when they fail. We confirm what your address requires and handle the submission where one is needed.
