A dining table with a 2 000 × 900 glass-fibre concrete top: 30 mm field, 50 mm edge, so it weighs 125 kg instead of 216 kg — no steel, cast face down, on an oak base with no hand-cut joints. A guide for advanced builders: batch-by-batch mix, a melamine chipboard mould with a profiled screed board and the load capacity of the top worked out.

Before you start building

This guide is informational material, not construction documentation or a professional assessment. Follow the instructions of tool and material manufacturers, safety rules and local building regulations. A piece built at home is not a certified product, even where the guide follows a European standard. Structures that carry people — beds, swings, decks, pergolas, children's equipment — should be checked by a qualified person before use. To the extent permitted by law, we accept no liability for the result of your build, property damage or injury arising from the use of this guide (Terms, section 9).
