Alluvial Ground Wants Checking, Not Assuming
River-laid material varies over short distances and can hide soft spots and old fill. We take the topsoil off and look at what is underneath rather than pricing a base off a guess.

Mowbray sits on a flat-topped alluvial shelf, Mowbray Hill, roughly twenty-eight metres above the Tamar. Alluvial ground is river-deposited ground, and that is worth knowing before you pour a slab on it.
Every suburb in Launceston throws up something slightly different. This is what we plan around here.
River-laid material varies over short distances and can hide soft spots and old fill. We take the topsoil off and look at what is underneath rather than pricing a base off a guess.
The shelf itself is flat, so access and set-out are straightforward once the ground is understood. It is the layers below that decide the base, not the surface.
Development here goes back to the late 1800s, so the housing spans well over a century. The concrete ranges from genuinely old to brand new and the right answer differs accordingly.
Bigger blocks in parts of Mowbray mean more shed pads, workshop floors and hardstand for a caravan or a boat than we pour in the inner suburbs.

Not a problem, but it is worth checking. The suburb sits on an alluvial shelf, and river-deposited ground varies more over a short distance than settled clay does. We strip the topsoil and assess the base rather than assuming.
Regularly. Bigger blocks in parts of the suburb mean more sheds, workshops and hardstand. The question we ask first is what is going to stand on it, because that sets the thickness and the steel.
It varies more than in most suburbs, because Mowbray has been developing since the late 1800s. We have replaced slabs poured in the 1950s and repaired others poured in the last fifteen years.
