Decks, Fences & Groundwork

Deck boards and framing, fence panels and posts, asphalt, excavation, trenches and pools.

• Asphalt Calculator Hot-mix asphalt in tonnes for a drive or path, from the area and compacted thickness, with the sub-base underneath.
• Cut and Fill Calculator Excavation and fill volumes for levelling a site, allowing for bulking of the spoil and compaction of the fill, with the net to import or remove.
• Deck Board Calculator Deck boards from the deck size, board width and gap — as boards of a stock length, linear metres and screws.
• Deck Framing Calculator Joists, beams, posts and footings for a deck frame, from the size and spacing — count and length only; the member sizes come from a span table.
• Fence Calculator Panels or bays, posts, rails, gravel boards and post concrete for a fence run, with the cost.
• Pool Chemical Dosing Calculator How much chlorine, pH adjuster or alkalinity increaser to add to a pool to move a test reading to a target, from the pool volume.
• Swimming Pool Volume Calculator Pool water volume in litres, cubic metres and gallons for rectangular, round, oval and freeform pools, with fill time and water cost.
• Trench Calculator Trench excavation volume, bedding, backfill and spoil for a pipe, cable or footing run.
