Westbuild General Purpose Dry-Mix Concrete - 20kg
Product Details:
• Pre-mixed blend of cement, sand and aggregate - just add water
• General purpose strength of 24-25 MPa
• Initial set in 45-60 minutes, giving you time to plumb posts correctly
• Rainproof, tear-resistant recyclable bag
• Ideal for securing fence and screen posts, footings, garden slabs and stumps
We recommend General Purpose concrete for setting aluminium posts. Unlike rapid-set mixes, its longer working time lets you level and plumb each post before it goes off - the difference between a straight fence and a rushed one.
