Blue Circle have developed a sand, cement and additive blend to create their strong and long lasting Postcrete formula. The purpose of Postcrete is to securely fit wooden, concrete and metal posts quickly and easily with just the addition of water and no mixing required. This product has a setting time of 10 minutes, cutting down on construction time and the time that posts must be manually supported for. All of Blue Circle's products comply with BS EN 9001 and ISO 14001 regulations to ensure the highest quality product possible. 1 bag of Postcrete will usually fix a square post with dimensions of 10 cm (4”) with a hole 20 cm (8”) wide x 75 cm (30”) deep.
It is important to note that Postcrete should not be used in projects that require particular compressive strength and normal up to standard site practices should always apply. It is also suggested that the product should be used for the 8 month shelf life indicated.
We also stock Blue Circle's Mastercrete formula.
