 Area & Distance Conversion Calculators – if you require a conversion for metres, yards, feet & inches etc. Sub Base Calculator – this estimator will provide the area in square metres (length x width) and the required compacted depth and the estimator will provide the approximate quantity of crusher run required for a consolidated sub base. Excavated Material Calculator (Metric) (also known as bulking) – enter the length, width and depth of excavation in metres. The results estimate will be given for the cubic metres of resultant spoil. Includes quantity and tonnes of excavations for sound rock, chalk, earth, clay, sand & gravel.Or if you prefer Excavated Material Calculator (Imperial) Concrete Calculator Readymix (Metric)– enter the length & width in metres and the depth in millimetres and the estimator will work out the total volume of concrete required for your project.Imperial Concrete Calculator Mix – On Site Concrete Calculator Mix on Site – enter the dimensions asked for and this will calculate the required quantities of sharp sand, gravel (aggregate) and cement.On Site Concrete Calculator – Imperial Plaster Estimator Calculator – calculate plaster. Enter the width & length or height of the wall or ceiling to be plastered in metres. The results will be provided for 25kg bags of bonding, browning, hardwall, multi finish, board finish, & 1st coat render. Assuming 11mm thickness. (see below for a more extensive internal plastering estimator). Stud wall Calculator (Metric) – calculate metal, wood or timber quantity. Enter the length and height of your wall or walls and this will estimate the quantities of stud partition, insulation, plasterboard, scrim tape, screws and plaster.Imperial Stud Wall Calculator Enter the length & width and either the height of the gable or the fall to calculate the areas for tiles, slates, felt etc. Mortar Calculator – enter the area of brickwork in square metres and this calculates the sand & cement requirements for a general 4:1 mix. (see below for a more extensive estimator). Brick, Block & Mortar Quantities Estimator – Calculator for Brick, block, sand, cement quantities for single skin, 6″, 9″ walls. Ready Mixed Screed Calculators– this calculates the approximate volume of ready mix screed required for the given dimensions. Screed Quantities Estimator – calculator for floor screed. Enter the dimensions asked for and this calculates individual quantities for sand, cement, lime, plasticiser etc with many variables. Render/Stucco Quantities Estimator – calculator for render. Enter the dimensions in the yellow boxes and this will calculate the approximate quantities required for external rendering including sand, lime & cement etc. Paving Bed Calculator – enter the square metres of your project and this will provide you with an estimate of the building materials required, including opc/cement by number of 25kg and tonnes of sand. Paving Cost Estimate – estimator for a given area and slab size, this works out the overall cost in square metres & yards of any size of flag or slab.
